Fill Line Residential RO System
Our fill line Reverse Osmosis filtration system comes in a compact, shelf-mount design, making it easier to install. You can use it to auto-fill your swimming pool, so you can treat the water before it enters the pool.
The fill line RO system is also ideal for light commercial use. It provides reliable water filtration for smaller quantities, such as spot-free rinses in car washes or lab humidification. Prices start at $4,512.00 plus shipping.

Nano Membrane RO Systems
The nanofiltration line is a simple water purifier intended to remove hardness and other contaminants using the pressure from a typical tap or well water line. Using nanomembranes, this system produces soft water while leaving low levels of minerals important to many food and processing applications. The inclusion of an optional dolly-mount makes these systems highly portable.
The nanosystems are available in the mid-range model sizes of 1500 and 3000 gallons per day (GPD) product water output.
Frame – welded tubular stainless steel
Membranes – 4040 thin-film nano
Vessels/Filter Housings – 4040 stainless steel/reinforced PP
Filters – 2.5” x 20” spun poly 10-micron sediment and carbon block, 1/2” fpt port housing • Water Quality Monitor – Digital feed water & product water TDS
Prices start at 5170.00 plus shipping.

THE BENEFITS OF A RESIDENTIAL INLINE RO
With an inline RO system plumbed directly to the swimming pool return system, you can always control the minimum and maximum TDS (Total Dissolved Solids) in the swimming pool. The benefit of this is that your swimmers will always have a defined water quality that they can count on. Plus, the RO filtration system allows you to continually keep the pool water within the parameters specified by plaster companies and equipment manufacturers in regard to warranties.
The ability to control the water quality will prolong the life of plaster. A new interior finish is a very expensive and time-consuming process (a re-plaster can shut a pool down for weeks and having a pool down for that period of time unnecessarily is something few desire). Installing a Reverse Osmosis filtration system greatly reduces the need to refinish your pool plaster, avoiding temporary closures.
Negate the need for a drain and refill to address water quality. While the accepted process for dealing with hard water or unbalanced water in the past has been a drain and refill (or partial drain and refill), this is not only wasteful but time-consuming. In addition, this process does not always address every issue (hard water, for example) and can also lend itself to a closed pool if the process is disrupted for any reason. A drain and refill will only provide water that is of the quality of the supply source and you are left to deal with that “quality”; RO systems allow you to control the water quality.
Chemical levels can be much lower and still provide a safe and sanitary pool. When the water chemistry is properly balanced, the chemical levels can be maintained at much lower levels, yet still meet Health Department spec. The ability to keep calcium, salt and even Cyanuric Acid (CYA) in range are the product of RO and cannot be obtained with chemical adjustment (like pH or Total Alkalinity (TA) can for example). The control of these inline Reverse Osmosis system means less time for the staff to struggle with proper water chemistry and safe swimming.
Waterborne disease and the possibility of sick swimmers are a very real concern and can (and do) provide the ability for extremely bad press and consumer scare. RO has the ability to filter out a very high percentage of solid material from water, as well as non-solids such as bacteria, viruses, giardia, e-coli, cryptosporidium, etc. There is no other process that is able to filter down to the level of RO or provide this level of safety or water quality. While typical chlorine and swimming pool equipment do a good job of providing safe water, the truth is that even the best pool filter system will only filter down to a particulate size of about 4 microns. RO far exceeds this level and removes much more than any pool filtration system can achieve.
Damage to pool equipment and visual impact to pool waterline tile and decking areas. High levels of calcium and salt (every gallon of liquid chlorine contains 10 ppm of salt) are very detrimental to swimming pools and their equipment. Excessively high salt levels (over 4,000 ppm) can become corrosive to not only the metals in the pool like handrails and light rings, but also to the heat exchanger of a pool heater. In commercial usage, pool heaters are a very expensive component of the pool circulation system, and no manufacturer will warrant a pool heater that has been damaged or ruined by high salt levels or calcification. RO allows you to always keep these items in a range that you choose, keeping them low enough to avoid damage or build up on expensive pool equipment, waterline tile or decking. A pool with stained and dirty calcium build up on the tile or deck is not inviting and does not look sanitary.
Fecal Incidents. This is possibly the most feared of occurrences possible in any swimming pool, and one that can cause many issues. Fecal incidents close pools and can (and do) cause severe health issues. The CDC (Center for Disease Control) has a specific protocol when dealing with these situations, which could include shutting the pool down completely, draining, sanitizing and refilling. This protocol, while inconvenient and time consuming, can also create concerns as to the safety of the water even after clean up.
General sanitization. All pools require a certain degree of attention to keep sanitary and balanced. When looking at the cost of the required pool equipment and chemicals (and/or chemical automation), the manpower to keep a swimming pool balanced, chemical demand and any automation (chemical feeders, remote monitoring, UV light, Ozone, etc.) a pool obviously becomes an expensive investment from day one. The ability to provide a safe and sanitary swim environment for guests, as well as maintaining the facility to avoid premature expense adds up quickly. Products that automatically monitor and maintain swimming pools in a safe state cut operating expenses and labor costs, not to mention the downtime costs or inconvenience when a pool is out of service.
