CARBON FILTER
This carbon block filter is manufactured with high purity Coconut Shell activated carbon with extruded activated carbon block construction. They do not release carbon fines and they are FDA compliant and they are NSF certified. These solid carbon block filters have combined the adsorption capability of carbon, with the ability of a solid block material to selectively strain out particles from the water that is being forced through the filter.
Activated carbon has an electro-positive charge added which results in this type of carbon attracting more chemicals and impurities. As the water passes through the positively charged carbon, the contaminants with their negative ions, are attracted to the carbon granules and thus extracted from the water.
The block of carbon strains out sediment, dirt, bacteria, microscopic worms, algae, asbestos and cryptosporidium. With just water pressure, this compacted solid carbon block is designed to filter sub micron size particles. This microstraining of the water will provide the cleanest and clearest drinking water available.
Activated carbon bonds to thousands of known chemicals. As water is forced through this solid block of carbon, it is forced to slow its flow speed and thereby increase the contact time with the carbon. This slowing of the flow allows the carbon bonding to take place and remove chemical pollutants like toxins, THM's, chlorine, pesticides, bad tastes, odors, etc.
Solid block carbon filters are very uniform and do not channel or bypass as conventional granular activated carbon (GAC) filters are know to do.
Because of the density of the solid block carbon filters, there is no room for bacteria to grow, so these filters do not become an incubator for bacteria as GAC filter are known to be.
These carbon block filters will fit most types of 10" x 2.5" filter housings on the market today and as noted previously, they will fit into the housings on nearly all water filtration and reverse osmosis systems. CTO carbon block filters preform well in both commercial and residential applications and they are the most widely used carbon filters on the market today.

PERMEATE PUMP by Aquatec
What does a Permeate pump do to improve my RO system?
A permeate pump is a simple, yet revolutionary devise. Powered only by the hydraulic energy of the brine water lost to the drain (i.e. no electricity required), the permeate pump forces product water into the storage tank, reducing membrane back pressure and maximizing available feed pressure. These pumps dramatically improve the efficiency of the RO systems water production, while reducing wastewater by up to 80%. In other words if your current system requires 6, 7 or more gallons of tap water to produce a gallon of pure water, adding a Permeate Pump should reduce this ratio below 3:1. Permeate Pumps can also bring storage tanks up to line pressure and then shut the system down when these tanks reach capacity, eliminating the need for an ASO shut-off valve. Other benefits include higher delivery pressures, faster R.O. water production, superior water quality, and extended filter/membrane life.
A Reverse Osmosis drinking water system requires strong water pressure to force water through the R.O. membrane and at the same time to flush the contaminants (bad elements) to the drain. The lower the water pressure, the less "good" water (permeate) you get and the more "waste" water you send to the drain. The average membrane rating is based on a constant feed water pressure of (50) psi using 77 degree water. The average "real life" application provides much less favorable conditions than this. The end result is that your R.O. system is drastically under-performing because of lower pressure and water temperature. To make matters worse, the pressure storage tank that stores your RO water compounds this problem. When full the RO storage tank has an internal pressure of about 60% of your tap water . This pressure is fighting the inlet water pressure (water coming into your RO system from your tap water source). The incoming water pressure is trying to force water through the RO membrane and into the tank. Even if you have good incoming water pressure of 60 psi, as the tank gets close to full, the actual pressure on the membrane is only 20 psi because of the off-setting pressure from the storage tank. This will result in reduced permeate (good water) production and vastly increase the flow of water to the drain.
A permeate pump will improve water quality through better membrane efficiency. In the typical RO system, increased tank pressure causes decreased pressure across the membrane. This decreased pressure causes a substantial decline in system performance and efficiency. A Permeate Pump enhanced RO system maintains full pressure across the RO membrane, even as tank pressure reaches its maximum levels. This reduced back pressure from the storage tank ensures better water quality (maximum TDS reduction), longer filter life and extended membrane life. In the standard RO system, increased tank pressure results in decreased recovery rates. A Permeate Pump enhanced RO system, by automatically minimizing back pressure will accelerate recovery rates (and reduce tank refill times) by up to 65%. Reduces wastewater. In typical R.O. systems, several gallons of wasted tap water (discharged to drain) are required to create a single gallon of purified R.O. water. A Permeate Pump enhanced R.O. system, will reduce wastewater by up to 80%.
HOW DOES THE PERMEATE PUMP REDUCE WASTE WATER BY 80%
The product water production rate is dependent on the pressure across the membrane, while the waste water production rate is mostly dependent on tap water pressure. As a bladder tank fills with water, its back pressure quickly starts to reduce the working pressure across the RO membrane, while the waste water flows as always. A curve can be plotted that shows progressively worsening ratios as the tank continues to fill. Half-way through the filling time, the ratio is already 8 or 10 to 1 and can be higher than 20:1 at the moment the ASO valve shuts off completely. The permeate pump makes the membrane perform like the bladder isn't there. The pump removes the pressure from the back side of the membrane and allows the system to function as if it were not forcing water into a tank. All of the work goes into making water. So, yes the pump can save up to (80%) of the normal waste water. The permeate pump works to eliminate this line pressure and allows the water to flow freely through the RO membrane and into the pressurized storage tank. An added benefit to the permeate pump is it drastically reduces the amount of waste water an RO produces. These pumps are used for pressure ranges from 30-75psi
A RO unit with a permeate pump and 60 psi coming in will continue to produce water until pressure in the tank reaches almost 60 psi. This is especially helpful for low-pressure installations. If, for example, you have a well system that provides only 40 psi, a standard RO unit will run, but it won't run well. The unit will shut down when storage tank pressure reaches 25 psi or so. With a permeate pump, the unit will put almost the full 40 psi into the storage tank.
What's best about the permeate pump, though, is the increased efficiency. With a standard shutoff system, as the pressurized storage tank fills, the RO unit must push against an increasing amount of storage tank pressure. With the permeate pump, the unit is shielded from this pressure and the RO membrane works in a virtually pressure-free situation, even when the tank is almost full.

If, for example, you have a well system that provides only 40 psi, a standard RO unit will run, but it won't run well. The unit will shut down when storage tank pressure reaches 25 psi or so. With a permeate pump, the unit will put almost the full 40 psi into the storage tank.
What's best about the permeate pump, though, is the increased efficiency. With a standard shutoff system, as the pressurized storage tank fills, the RO unit must push against an increasing amount of storage tank pressure. With the permeate pump, the unit is shielded from this pressure and the RO membrane works in a virtually pressure-free situation, even when the tank is almost full.
