The reverse osmosis systems work by using pressure to force a solution through a membrane, retaining the solute on one side and allowing the pure solvent to pass to the other side. This is the reverse of the normal osmosis process, which is the natural movement of solvent from an area of low solute concentration, through a membrane, to an area of high solute concentration when no external pressure is applied.

Its essentially a cross flow filtration technique wherein water is passed parallel to membranes at higher pressure.the

Advantages of reverse osmosis system :

• Doesn’t require any regenrants
• Low maintenance & hassles free automatic operation.
• Easy maintenance

With the use of sophisticated software's we at DME design reverse osmosis system which removes TDS up to 99%. The product water can be used for different applications with further specific treatment such as:

• Packaged drinking water plant with ozonation & UV disinfection
• Pharmaceutical industry for bulk drug manufacturing
• High pressure boiler feed water
• Power generation plants
• Hospitals
• Specialty chemicals manufacturing

MOC: SS/FRP/PVC

Pressure sand filters are most suitable for removing the suspended solids from water. In these filter, the filtration medium has multiple layer of sand, where each layer has different specific gravity.

Pressure sand filters are provided with water pump for generating necessary operating pressure. For Filtration, water is passed through multi-grade sand filter at a pressure of 3.5 kg/cm2 that reduce the presence of suspended solids in the water.

The filter effectively removes suspended solid of sized up to 30-50 micron to around 5 ppm. The pressure sand filter requires to be washed for 20-30 minutes with normal water.     

Application:

• Turbidity arresting
• Suspended solids, organics & in organics removed for water

• MOC: MS, MSRL, FRP

MODES of operation : Manual, semiautomatic, fully automatic
