Reverse Osmosis Plants

Reverse osmosis is a high-pressure energy efficient water separation process. It is a method of extracting essentially pure and fresh water from polluted or salt water by forcing the water under pressure against a semipermeable membrane, which passes the pure water molecules, but filters out salts and other dissolved impurities.

In the DWTPL RO System, the water is treated at the molecular level by the reverse osmosis process thus ensuring the removal of all impurities such as excessive salts, micro-organisms, and other products left behind by disinfection products and chemical toxins. This principle is also used in our Desalination Plants for extracting pure and fresh water from sea water.

FEATURES – The DWTPL R. O. System is a viable economic alternative as compared to other conventional distillation processes due to the multiple benefits it offers.

  • Requires less than 50 % of energy as against Thermal Plants.
  • Operates at Ambient Temperature.
  • Uses non-corrosive Polymer Materials.
  • Compact sized, requiring a very small place for installation.
  • Quick start-up and shut down.
  • Easy to operate with minimal operator training.
  • Any layman can be trained to operate the plant within few days.
  • Only one person is enough to operate the plant.
  • Operating cost is negligible.
  • The ready availability of spares at low cost.

Desalination

Reverse osmosis is an increasingly common method of desalination, because of its relatively low energy consumption.

Reverse osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other effluent materials from the water molecules.

Sea water reverse osmosis (SWRO) desalination, a membrane process The typical single-pass sea water reverse osmosis system consists of:

  • Intake
  • Pretreatment
  • High pressure pump (if not combined with energy recovery)
  • Membrane assembly
  • Energy recovery (if used)
  • Remineralisation and pH adjustment
  • Disinfection
  • Alarm/control panel
