Clear - Pure - Water

For the marine Enthusiast, it is well known that the waters surrounding coral reefs are among the cleanest and the most beautiful in the world. So, if you intend to bring the beauty of a coral reef into your home, you must provide the cleanest water possible.

Ordinary tap water, contaminated by substances harmful to delicate aquatic life, is a growing problem for the concerned hobbyist. These toxic substances must be removed from the water to help insure your aquarium success is one of worry-free enjoyment.

SpectraPure offers a variety of Reverse Osmosis (R.O.) and Deionizing (D.I.) systems. These include our new improved wall-mounted CSP and CSP-DI models. Accessories can easily be added such as the drinking water kit, liquid level control, booster pumps, and the new SpectraPure Auto-Fill water replenishment system. Auto-Fill completely automates replacing the evaporated water in your aquarium, and then automatically fills an additional reservoir with purified water.

Going a stage beyond Reverse Osmosis (R.O.) Spectrapure has combined the most effective known methods of water purification into one integrated unit. Our new improved CSP-DI systems incorporate solid sediment and carbon block pre-filtration, an advanced Thin Film Composite (T.F.C.) R.O. membrane, and our custom formulated mixed bed deionization (D.I.) cartridge (no mess - easy to change D.I. cartridge).

The result is laboratory grade purified water, suitable for demanding ultra-high purity applications such as marine, reef and fresh water aquaria.


How Does Reverse Osmosis (R.O.) Work?

Tap water first passes through a high efficiency solid block sediment filter where silt, sediment and particulates are removed. Water is then forced through a solid block carbon which efficiently adsorbs chlorine, chloramines, pesticides, and other harmful organic chemicals.

The water, now stripped of membrane-damaging particles and chemicals, then flows into the R.O. module where pure water molecules are forced through the R.O. membrane leaving salts, bacteria, viruses, hardness and other impurities to be flushed from the system.

Reverse Osmosis membranes, although very good at removing contaminants, still allows trace amounts to pass through. Nitrates, phosphates and silica are among these substances that are not as efficiently removed. By further processing Reverse Osmosis water through mixed bed deionizing (D.I.) resins, even those difficult to remove chemicals, are reduced to almost undetectable levels.


Introduction

Line Pressure Operated RO systems will:

SpectraPure Reverse Osmosis Systems provide superior rejection of ionic, organic, and particulate impurities and thus produce contaminant-free water.   We use superior quality, 100% tested, TFC membranes in our RO systems.   Line-pressure operated systems operate on household water pressure.   Your feed water pressure should be between 40 - 100 psi. (2.75 - 6.9 bar).   TFC membranes used are rated at standard feed conditions of 60 psi (4.1 Bar) at 77F (25C), and 500 ppm TDS (750 uS conductivity).  

Important Note:  For every gallon of purified RO water there will be 3 gallons of waste water.


New - Improved Models
Two Stage Deluxe CHP Systems (CHP-D)

MODEL CHP DELUXE Countertop - Portable Two Stage. Provides high performance water filtration with an economical configuration. This two stage system uses the same TFC membrane used in the CSP series. By omitting the wall mount bracket and sediment pre-filter, a significant cost reduction is possible. Yet in low sediment feed water applications, performance is equal to the CSP models. Includes TFC membrane, clear filter housing and 5 micron carbon filter block pre-filter which greatly enhances chlorine and contaminant removal. Also includes a pressure gauge to monitor pre-filter plugging. Order this model if you do not have a lot of sediment in your water. Deluxe model includes a clear carbon filter housing.







CSP DELUXE RO
Three Stage Deluxe CSP System (CSP-D)

Wall Mounted Three Stage. New Improved CSP Model comes standard with pressure gauge, filter wrench and 3/4" standard connect. By replacing our spun polypropylene filter with a high efficiency solid block sediment filter, we are now able for the first time to use a 0.5 micron carbon block pre-filter. The 0.5 micron carbon block has greatly enhanced chloramine and chemical contaminant removal while further protecting the TFC membrane from damage or plugging. Clear filter housings included. Purity monitor optional.


Introduction
RO/DI Systems will:

SpectraPure Reverse Osmosis & Deionization Systems (RO/DI) provide superior rejection of ionic, organic, and particulate impurities and thus produce contaminant-free water. Line-pressure operated systems operate on household water pressure. We use superior quality, 100% tested, TFC membranes in our RO systems. TFC membranes used are rated at standard feed conditions of 60 PSI (4.1 Bar) at 77F (25C), and 500 ppm TDS (750 uS conductivity).  Every single membrane is tested for flow and rejection. The deionization cartridges have a mixed-bed multi-layered design especially optimized for muse after RO and Distillation systems.



CSP-DI
Four Stage CSP-DI Systems
Wall Mounted Four Stage. For a level of purity beyond R.O., these units offer the most effective known methods of water purification into one compact system. The finest available ultra purified mixed bed deionized (D.I.) resins are now combined with high performance R.O. systems.

The addition of mixed bed D.I. provides the highest capacity removal of nitrates, phosphates, silica, ammonia and other harmful contaminants. These ultra purified resins, in no mess disposable cartridges have been rinsed of all traces of harmful residual chemicals. The result is laboratory grade water suitable for the most demanding ultra high purity water needs. RO/DI water use includes - marine/reef aquariums, fresh water aquariums and many other high purity water uses. Standard electronic purity monitor, unlike visible dye indicators, ensures exhausted D.I. cartridges are quickly replaced prior to reintroducing captured impurities to the water. Includes TFC membrane, 0.5 micron high efficiency solid block sediment filter, 0.5 micron carbon block filter, pressure gauge, clear filter housings, electronic purity monitor and D.I. resins. The average life span of the resin cartridge is between 300 to 900 gallons depending on the quality of the water being processed.


Five Stage SpectraPlus RO/DI systems

SpectraPlus Five StageSpectraPlus systems are a major improvement over all other RO/DI Systems using single DI cartridges, because they assure you never unexpectedly running out of DI water nor releasing contaminants from exhausted DI resins. These systems come with two 10" Deionization cartridges with the electronic purity monitor between the first and second cartridges. This provides a major advantage over systems using just one DI cartridge. When the purity light turns red, it indicates that only the first cartridge is exhausted and that the second cartridge still has about 99% of it's original capacity left. By removing the exhausted cartridge, rotating the second cartridge to the first position and putting a new cartridge in the second position, you are assured of never releasing any contaminants into the water while maintaining extremely high levels of purity. The electronic monitor gives you a 50% exhaustion point which is more than ample warning for replacement of the second DI cartridge.

Going two stages beyond Reverse Osmosis (RO), SpectraPure has combined the most effective know methods of water purification into one integrated unit operating from line-pressure (no electricity required). Our new SpectraPlus RO/DI systems incorporate solid sediment and carbon-block pre-filtration, an advance Thin Film Composite RO membrane, and our custom-formulated multi-layered, mixed bed deionization cartridges. The result is laboratory grade purified water, suitable for demanding ultra-high purity applications.

Tap/well water first passed through a 0.5 micron micro-tec sediment filter where silt, sediment and particles are removed. Water is then forced through a high efficiency 0.5 carbon block filter. This matrix of micro-pulverized carbon efficiently adsorbs chlorine, chloramines, pesticides and other harmful organic chemicals. The water, now stripped of membrane damaging particles and chemicals, flows into the RO module where filter water molecules are forced through the RO membrane leaving salts, hardness, bacteria, viruses, pyrogens and other impurities to be flushed from the system. Reverse Osmosis membranes, although very good at removing contaminants, still allow trace amounts to pass through. Nitrates, phosphates and silica are among these substances not fully removed. By further processing RO water through two multi-layered, mixed-bed deionization cartridges, even those difficult to remove chemicals are reduced to virtually undetectable levels.

The SpectraPlus systems standard with a 10" 0.5 micron sediment pre-filter, a 10" 0.5 micron carbon block pre-filter, a Thin Composite membrane, two 10" DI cartridges, easy to use electronic purity monitor, pressure-gauge (to indicate pre-filter replacement and input line pressure gauge.


New!  Spectra+ 2000 5-Stage RO/DI System


Spectra+ RO/DI In a continual effort to provide the reef aquarist with the latest and best technological improvements, SpectraPure introduces the new SPECTRA+2000 RO/DI System. SpectraPure's new 99% UltraHigh Rejection Membranes have the highest rejection available and remove twice as much silica, phosphates and nitrates as 98% rejection membranes. These UltraHigh Rejection Membranes produce a much higher purity reverse osmosis water then conventional TFC membranes. This in combination with our super-capacity two-bed deionizing system provides the ultimate removal of algae promoting substances and the longest deionizing cartridge life, significantly reducing the cost of ownership.

This super-capacity DI system consists of a newly developed color-indicating DI resin cartridge with twice as much phosphate/silica removal resin as in previous designs. When the resin changes color upon exhaustion, the cartridge should be removed and replaced with a new cartridge before any contaminant's can be passed on to the next stage. The final stage consists of a semiconductor mixed-bed cartridge with an electronic purity monitor to determine the exhaustion point.

The SPECTRA+2000 is available in 15, 25, 35, and 70 (twin membrane) gallons per day systems. The 70 GPD system uses two 35 GPD membranes in series, maintaining a 99% rejection rate, which the membrane life of the system in comparison to a single 70 GPD membrane system.

SPECTRA+2000 Systems are equipped with the finest pre-filtration 0.5 micron MicroTec pre-filters and 20,000 gallon chlorine capacity carbon black pre-filters. Clear Ametek filter housings and a standard pressure gauge mean better visibility to system performance. No more guessing plugged pre-filters. Also included is a filter wrench and a 3/4 inch garden hose adapter.



Sizes available - 15, 25, 60, 80 and 160 gallons per day.
Numbers indicate delivery rate in gallons per day (GPD) at standard feed conditions of 60 PSI and 77 F. Lower pressures or temperatures have significant effects on production. TFC membranes provide overall (TDS) rejection of 98%.

FOUR STAGE DELUXE DRINKING WATER SYSTEMS (DWS)

Drinking Water Systems SpectraPure's deluxe drinking water systems (DWS's) operate entirely on city water pressure - no electricity required It offers you a superior four-stage filtration which combines 2 pre-filters (0.5 micron micro-tec sediment & 0.5 micron carbon block) with a TFC membrane and a 60 cu. inch, granulated post carbon filter. The water first passes through the pre-filters. where sediment, chlorine, pesticides and many other organic chemicals are removed. Water then flows into the RO module where dissolved solids (hardness, sodium heavy metals), bacteria, viruses are removed. The filtered water is then collected in a pressurized storage tank. After the tank is full, the automatic shut-off valve turns the system off. When water is withdrawn from the unit, it passes through the final carbon polishing filter, assuring fresh, great tasting drinking water every time the system includes a pressure-gauge which makes it easy to trouble-shoot. A 15-2O% drop in the feed water pressure indicates pre-filter plugging. The pressurized storage tanks are available in 3 and 10 gallon sizes. The system also comes with code-approved air-gap faucet, manual tank shut-off valve. an auto-shut off valve & a filter wrench for easy cartridge replacement.

AUTOMATIC LEVEL CONTROLLERS

Liquid Level Controller (LLC-S)


LIQUID LEVEL CONTROL











Liquid level controller for Single Tanks (LLC-S) is a the most advanced means of controlling liquid levels on single or multiple reservoirs and is ideal for replenishing evaporate water in aquariums or liquids in other constant level containers. An on-board air pressure activated electrical switch opens a solenoid valve when the liquid level drops approximately 1" and closes it when the liquid level rises back to the original level. Research at Spectrapure shows that the liquid level controller provides a significant advantage over conventional float and back-pressure activated automatic shut-off valves by maximizing the duration of membrane operation. This minimizes the build up of impurities due to membrane creep (the small amount of impure water that is characteristic of the membrane at the onset of pure water production).

LLC requires no drilling and all wetted components are constructed of inert and saltwater safe materials. Power is provided by a plug-in 24 volt AC (UL listed and CSA approved) transformer. Highly recommended! Prevents overfilling and floods. After flooding my basement twice, I now use one!
The single reservoir model comes with the LLC unit (which includes a switched 24 VAC outlet for controlling a booster pump or other 24 VAC operated devices), compression fittings and 10 feet of tubing for remote mounting of the sensor.

Multiple Tank Liquid Replenisher (LLC-M)




SpectraPure´s liquid level controller (LLC) is the most advanced means of controlling liquid levels on single or multiple reservoirs and is ideal for replenishing evaporated water in aquariums or liquids in other constant level containers. A sensitive air pressure switch opens a solenoid valve when the liquid level drops approximately 1" and closes it when the liquid level rises back to its original level. Research at SpectraPure shows that the liquid level controller provides a significant advantage over conventional float and back-pressure activated automatic shut-off valves by maximizing the duration of membrane operation. This minimizes the build up of impurities due to membrane creep (the small amount of impure water that is a characteristic of the membrane at the onset of pure water production). LLC requires no drilling and all wetted components are constructed of inert and salt-water safe materials. Power is provided by a plug-in 24 volt AC (UL listed and CSA approved) transformer.

The multiple reservoir model comes with the LLC unit (which includes a switched 24 VAC outlet for controlling a booster pump or other 24 VAC operated devices), compression fittings, 10 feet of tubing for remote mounting of the sensor, a Turbo Bladder, auto shutoff valve, ball valve, check valves and fittings and one float valve for one additional reservoir. The system may be expanded to include more reservoirs by adding the optional LLC expansion kit (see table below). For additional overflow protection a secondary mechanical float is also included with every LLC.

Hook-Up Diagram



Power Liquid Level Controller (PLC)




The Power Liquid Level Controller uses a sensitive air pressure switch to energize or de-energize an AC outlet which can be used to switch a power head or a 115 volt pump up to 3 Amps continuous duty. The unit can be set to turn a pump on or off with changing water level and is extremely useful for continuous water change systems.

Hook-Up Diagram



Float Level Controller (FLC)

SpectraPure FLC provides an economical way to automatically fill open reservoir storage tanks. The automatic shut-off valve in conjunction with the mini-bladder provides positive shut-off and completely shuts off the waste water and product water lines thus conserving water. Float level controller includes ASO valve, stainless steel float, check valve, mini-bladder tank, a straight ball valve, tubing and necessary fittings. Buy one float kit for filling every additional sump or reservoir. Our float kit (SPFK) includes a stainless steel float, union T, and other necessary fittings. The installation of float requires a 9/16" mounting hole in the tank. Note: Do not use the float level controller for automatic replenishment of evaporated water. For those applications, we recommend either our SpectraPure Auto-Fill system (SAF) or our liquid level controller (LLC).

Pre-Filter Replacement Guide
For maximum contaminant removal and long membrane life, the sediment and carbon pre-filters must be changed at 6-month intervals. If your water contains a great deal of sediment or chlorine, the pre-filters might have to be changed at more frequent intervals to maintain an adequate production rate. A main function of the Carbon Block pre-filter is chlorine removal to protect the TFC membrane from damage. Carbon filters have a finite capacity for removing chlorine, and the lifetime will depend on the level of chlorine in the water and the amount processed.
CARBON FILTER


Replacement Carbon Block Pre-Filter - 5 micron for CHP. 0.5 micron for CSP models. Carbon Block filters remove chlorine, organic chemicals and chemicals that contribute to taste and odor. These filters act as almost absolute-rated sediment filters. They are much more efficient than the granulated carbon filters because there is no channeling or bypassing of fluids. They also have higher adsorptive efficiency and higher turbidity reduction than granular filters.



SEDIMENT FILTER Replacement Micro-Tec Solid Block Sediment Removal Pre-Filter - 0.5 micron for CSP & CSP-DI models.
High efficiency depth gradient density filter cartridges with almost absolute micron ratings. Strongly recommended for areas with extremely high sediment levels. The gradient pore structure of these cartridges captures larger particles in the outer sections of the filter cartridge while providing highly efficient and consistent removal of smaller particles in the inner most sections. The proprietary core provides the cartridge with greater mechanical strength and temperature resistance than core less melt blown filter cartridges. These cartridges are constructed of 100% high purity polypropylene and are surfactant, binder and adhesive free.

Replacement Micro-Spun Sediment Removal Pre-Filter - 1.0 micron for CSP & CSP-DI models. Micro-Spun cartridge's gradient density affords substantially increased filter life and effectiveness over string wound and pleated sediment filters. These filters remove larger particles which blind-off ordinary surface filters on their outer layers, while reducing the finer particles on their inner layers. The design maximizes the utilization of the filtration en-us/media. There are no leachables or extractables from these filters as they are made of 100% virgin polypropylene en-us/media.


DI CARTRIDGE

Replacement Mixed Bed DI No-Mess Cartridge - For CSP-DI models. Mixed bed multi-layer deionization cartridges are fabricated with semiconductor grade resins for the highest purity. They are capable of producing greater than 17 MegaOhms/cm purity water. They are the first deionization cartridges designed to reduce silica, nitrates & phosphate levels in the low ppb range. These newly formulated cartridges far exceed the performance of previous cartridges, offering enhanced contaminant removal, longer life and higher purity.

Replacement Mixed Bed Color Change DI No-Mess Cartridge - Same as above with color changing from purple to yellow when DI Resins are exhausted. IMPORTANT NOTE: DI cartridges have a shelf life of one year. The average life span of the resin cartridge is between 300 to 900 gallons depending on the quality of the water being processed.
