In the chamber, pure water is allowed to pass through the membrane material and exit as purified permeate water. Dissolved mineral salts are not allowed to pass through the membrane and become a concentrated reject stream that is sent to drain. These RO systems use high-rejection membranes to achieve a minimum average NaCl ionic rejection of 95 percent. This series comes with a pre-selected assortment of features for monitoring and operation. Stainless steel membrane housings, inlet and outlet pre-filter pressure gauges, low pressure switch with delayed auto restart, permeate pressure switch, adjustable reject recycle, permeate and reject water flow meters, permeate water check valve, inlet solenoid valve, membrane feed water pressure gauge, adjustable reject valve, and membrane auto flush are all standard features.

The standard systems are designed to feed an atmospheric storage tank or a pressurized bladder tank. Reverse osmosis water has a wide variety of applications including municipal water treatment, steam boiler and steam sterilizer make up, laboratory use, spot free rinsing, ice and beverage water, water for cooking, food processing, metal plating and finishing, as well as water for humidification.

Reverse osmosis is also the pretreatment of choice for ion exchange type de-ionization DI systems. Using RO water as make up to a DI system reduces the exhaustion rate of the DI resin by up to 95 percent saving time, money, and chemicals associated with DI resin regeneration. The Series PWRO uses advanced design with state-of-the art technologies and high-quality components to assure years of trouble-free performance.

Includes many standard features that are only available as options on other reverse osmosis systems. Note: Feed Water must be pretreated for scale prevention softened , de-chlorinated carbon filter , and free of sediment. May be operated on other feed waters with reduced capacity.

Percent rejection is based on membrane manufacturers specifications; overall system percent rejection may be less. Reduce installation labor with these complete tank and pump packages with components pre-installed to save time and money. Grundfos MQ3 Pump This unique pump is included in the package for re-pressurization. It is a stand alone component, operating independently. Simply plug it in directly to a VAC outlet and the pump turns itself on and off and adjusts speed based on flow.

The OneFlow system is a single cartridge-based system that may be installed on a cold water line prior to a water-using device water heater, hot-beverage system, appliance, steamer etc. OneFlow prevents scale by transforming dissolved hardness minerals into harmless, inactive microscopic crystal particles.

These crystals stay suspended in the water and are passed to a drain, thereby having a greatly reduced ability to react negatively with plumbing surfaces, as opposed to dissolved hardness minerals. The system requires very little maintenance, no backwashing, no salt and no electricity. Typical hardness problems, especially build-up of scale in pipes, water heaters, boilers and on fixtures are no longer a concern. OneFlow is not a water softener.

It does not add chemicals. It is a scale prevention device with proven third party laboratory test data and years of successful Food Service and Commercial applications.

OneFlow is the intelligent scale solution and is a great alternative to water softening ion exchange or scale sequestering devices. Cartridge should be replaced every 12 months Cartridge should be replaced every 12 months Cartridge should be replaced every 12 months.

The OneFlow system is a dual cartridge-based system that may be installed on a cold water line prior to a water-using device coffee maker, espresso machine, post-mix system or other appliance that requires protection from the ill effects of hard water.

OneFlow works exceptionally well where the water is being heated or brought to steam. The system requires very little maintenance, no backwashing, no salt, and no electricity. Typical hardness problems, especially build-up of scale in heating elements, boilers, and steamers, are no longer a concern.

It does not add chemicals or remove any minerals. OneFlow is the intelligent scale solution with chlorine reduction as a great alternative to water softening ion exchange or scale sequestering devices. Cartridge should be replaced every 12 months Cartridge should be replaced every 12 months Cartridge should be replaced every 12 months Cartridge should be replaced every 6 months Cartridge should be replaced every 6 months Cartridge should be replaced every 6 months.

The OneFlow system is a single cartridge-based system that must be installed on a cold water line prior to a water-heating device water heater or tankless water heater for single tankless heaters. These crystals stay suspended in the water and are passed to a drain. Typical hardness problems, especially build-up of scale in heating elements, pipes, water heaters, boilers and on fixtures are no longer a concern. It is a scale prevention device with proven third party laboratory test data and years of successful commercial, residential and food service applications.

Media should be replaced every 3 years Media should be replaced every 3 years Media should be replaced every 3 years Media should be replaced every 3 years Media should be replaced every 3 years.

OneFlow prevents scale by transforming dissolved hardness minerals into harmless, inactive microscopic crystal particles, as water travels through the media filled tank. These precipitated micro-crystals stay suspended in the water and are passed to a drain, thereby having a greatly reduced ability to react negatively like dissolved hardness minerals do.

They are suitable for commercial applications with dechlorination flow rates up to gallons per minute with media bed sizes ranging from 1 to 35 cubic feet in size. If higher flow rates are required multiple units can be installed in parallel.

The media bed is cleaned of captured sediment by periodic backwashing and flushing. This cleaning cycle is time clock demand initiated and can be programmed to occur at any time that is convenient for the user. All steps of the cleaning cycle as well as returning to service are fully automatic and do not require manual actuation.

Watts Pure Water Series PWC activated carbon filters are designed for point of use or point of entry applications where dechlorinated water is required. Chlorine, an oxidizing agent, is added to municipal water to destroy micro-organisms.

Chlorine causes the destruction of reverse osmosis membranes and polymer based ion exchange resins. Chlorine also causes objectionable tastes and odors in certain applications. Activated carbon in general is used for dechlorination, removal of taste, color, and odor caused by organics, as well as trace hydrocarbon removal from water.

For applications involving trace hydrocarbon removal or taste, color, and odor removal due to organics, consult your Watts representative for proper sizing and carbon selection. Watts Series PWC activated carbon filters utilize 12x40 mesh coconut shell carbon granules which are tailored for chlorine removal. Coconut shell carbon media has a high micro-porosity which makes it ideally suited for the removal of low molecular weight contaminants such as chlorine.

Another advantage of this carbon is its superior hardness, which combined with a de-dusting process in its production, creates an exceptionally clean product with low fines. These systems are ideal for food and bottled water processing, restaurant drink station water treatment, commercial ice production, soft drink water processing, reverse osmosis pretreatment, ion exchange resin pretreatment, and general dechlorination of municipal water.

They are suitable for commercial applications with flow rates up to gallons per minute with media bed sizes ranging from 1 to 20 cubic feet in size. Micro Z is a naturally occurring form of Zeolite that offers superior filtration characteristics over and above sand, anthracite, and garnet products currently in use today.

The key to Micro Zs performance is its hydrophilic properties combined with a jagged external surface texture. This gives Micro Z a sediment holding capacity of 2. Micro Z has a micron nominal particle size removal rating versus micron with other conventional back-washable medias. Reverse osmosis pretreatment, micro and ultra filtration system pretreatment, cartridge filtration pretreatment, sediment reduction in city and rural water, municipal water filtration, as well as general turbidity reduction are all common applications for the Watts Pure Water Series PWM Micro Z filter systems.
