Reverse Osmosis is a process used to remove dissolved ions from water. When designing RO Treatment systems a complete analysis of RO water chemistry should be done in advance. Reverse Osmosis relies on pressure forces the water through a semi-permeable membrane element normally contained in a reinforced Fiberglass Housing. RO membranes reject most of the dissolved solids (Salts and minelrals) as well as any small particles in the feed water. Thus the permeate water which has passed the membrane contains a relatively low concentration of ions compared to the reject (or concentrate) which contains all of the ions which did not pass the membrane.

Applied Water Solutions provides reverse osmosis systems capable of removing 95 to 99% of the dissolved minerals and at least 99% of the bacteria, particles and organics (including pyrogens) having a molecular weight greater than 250.

Typical RO Membranes are constructed from TFC or polyamide material for operation using feed water that may range in pH from 2 to 12 with a maximum temperature of 140 degrees F. The standard RO unit design provides a minimum of 70% overall operational efficiency. All Water Systems are controlled through central Microprocessor Controls with integrated monitoring and control of the following:

The Moving Bed Biofilm Reactor or MBBR process is based on the Aerobic Biofilm Principle utilizing activated sludge and other Biofilm systems. The process, the Biofilm carrier elements constructed from polyethylene provide large protected surface area for the Biofilm, leading to optimal conditions for the bacteria culture to develop and grow. The Biofilm provides greater environmental stability for the bacteria to grow, resulting in required space allocation compared with other biological systems. MBBRs can be designed for new facilities to remove BOD/COD from wastewater streams or for nitrogen removal. Existing activated sludge plants can also be upgraded to use MBBR technology. This new purification Technology has been installed in several facilities around the globe with exceptional water quality results.

The two types of UF that are offered today are spiral wound, and hollow fiber. Spiral UF has been successfully utilized as pretreatment to RO, including potable water treatment applications, waste water treatment applications, and in the food and beverage industry for liquid concentration.

Ultrafiltration is a membrane process with the ability to separate molecules in solution based on size. It is a pressure driven process with a typical nominal pore size of 0.01 micron (100,000MWCO), and configurations are either cross flow or dead end filtration. UF removes bacteria and protozoa, including Giardia and cryptosporidium. Ultrafiltration reduces turbidity to < 0.1 NTU and removes 6 log of viruses. UF serves as an ideal as pretreatment for reverse osmosis systems, final treatment in the pharmaceutical industry, and for potable water applications for a wide range of feed sources in the municipal drinking water market. Hollow fiber multibore membranes are the most resilient and reliable membranes being manufactured today.

Media Filtration Technologies
Pretreatment is a critical parameter in the design of any water treatment system. Included below are some standard design protocols associated with media filtration technologies. Correctly sizing the pretreatment system and understanding feed water composition will serve to minimize maintenance and allow for greater efficiency and control of all subsequent downstream water systems equipment.

Multimedia Filtration
The filter body shall be constructed of reinforced, lined fiberglass; epoxy coated steel or other such materials of sufficient thickness as required by operating conditions to insure a five-year minimum operational life. The vessel shall be designed for a working pressure of 150 PSIG and shall be provided with manholes for loading and inspection of media. The unit shall incorporate a central bottom distributor designed to insure even flow distribution over the entire media bed. The media shall consist of layers of anthracite, quartz or silica sand and garnet, graded in density. Unit backwash shall be initiated by a central microprocessor and controlled automatically using a multi-port valve. The filter shall automatically cycle through the positions of backwash, rinse and return to service.

Water Softener
The filter body shall be constructed of reinforced, lined fiberglass; epoxy coated steel or other such materials of sufficient thickness as required by operating conditions insuring five-year minimum operational life. The vessel shall be designed for a working pressure of 150 PSIG and shall be provided with manholes for loading and inspection of media. The unit shall incorporate a central bottom distributor designed to insure even flow distribution over the entire media bed. The unit shall be provided with high-capacity, non-phenolic ion exchange resin having a minimum exchange capacity of 30,000 grains/ft3. Unit regeneration shall be initiated on totalized process flow by a central microprocessor and controlled automatically using a multi-port valve. The filter shall automatically cycle through the positions of backwash, brine draw, slow and fast rinse, brine tank refill and return to service. Normal unit design shall be provided with a brine tank of sufficient capacity to provide for seven days of continuous service prior to refill.

Activated Carbon
The filter body shall be constructed of reinforced, lined fiberglass; epoxy coated steel or other such materials of sufficient thickness as required by operating conditions, ensuring ten-year minimum operational life. The vessel shall be designed for a working pressure of 150 PSIG and shall be provided with access ports for loading and inspection of media. The unit shall incorporate a central distributor designed to insure even flow distribution through the activated carbon elements. The unit shall also monitor total gallons processed and provide feedback when activated carbon replacement is required.
