Reverse Osmosis (R/O) is a water treatment process in which water is forced through a semi-permeable membrane that has very small holes or "pores". It is extensively used for treating water from the impurities. Some of the attractive features include: Helps in removing and separating possible water contamination. Used in water treatment plants where high purity of water is required.

RO can be used for the following feed water types and applications: brackish water, potable water, water re-use, polishing waste water, UF permeate, and sea water desalination.

Deionization (DI) or Demineralization System, through ion exchange, is a two-stage process used to virtually remove all ionic materials in water. In the ion exchange process, positively and negatively-charged minerals present in the feed water are exchanged with the hydrogen and hydroxyl ions in the cation and anion resins, respectively, to produce pure water.

This process results in high-purity water from a system that is easy to use and maintain. It can be used to remove unwanted minerals in water, to treat boiler feed water, and to obtain high-resistivity production water for semiconductor industry.

Water Softener Systems employ the principle of ion exchange, a reversible chemical process. The hardness ions present in the feed water, such as calcium and magnesium, are replaced by sodium ions from the resin. This is an important process in different applications because hard water can clog pipes, restrict water flow, and reduce heat exchange efficiency of heat exchangers.

The benefits of using Water Softener include the following: less scale build-up in pipes, fixtures, and appliances and reduced mineral-derived odors. It can also be used for industrial applications such as treatment of boiler feed water.

Media Filtration Systems serve as pre-treatment for Membrane and Ion Exchange Systems. These are used to remove contaminants in water such as suspended solids, odor, color, chlorine, iron, and manganese.

Multimedia Filtration reduces turbidity and suspended solids as well as coagulated contaminants. It makes use of layers of anthracite and silica sand.

Activated Carbon Filtration operates through the principle of absorption. It removes taste, odor, color, organics, and chlorine.

Ultrafiltration (UF) Systems are widely used in water purification to remove contaminants such as suspended solids, bacteria and viruses. Features of UF include: minimum pumping energy requirement, chemical resistant, can handle wide pH range, backwashable, easy to operate and maintain, low investment cost, no phase change, no contaminant residue caused by chemical reaction, and high recovery ratio (up to 95%).

It has a wide range of applications including: potable water treatment, wastewater recycling, juice clarification, wine filtration, dairy processing, and pharmaceutical drug processing.

Membrane Bioreactors, simply called MBRs, offer the optimum solution wastewater treatment and recycling. The membrane barrier eliminates the secondary clarifier and allows the activated sludge to be more highly concentrated.

The benefits of using MBR include the following: improves water quality, adds as an option for wastewater reuse, lowers down capital cost, reduces plant space requirements, minimizes operational problems, reduces energy demand, and provides high reliability.
