DOW RO Membrane Model - BW30-365 8040

DOW RO Membrane Model - BW30-365 8040


Specifications :-

  • BW30-365 produces every unit of purified water at minimal cost and very quality.

  • Chances of membrane fouling are very low due to the thick feed spacer provided.

  • Has good filtration capacity and is very durable for long life.

  • As the shell is made up of fiberglass hard shells so it can withstand high pressure drops.

  • Due to its widest cleaning pH range  of (1-13) it is able to provide the most effective cleaning performance.

Reverse osmosis (RO) is a water purification process that uses a semi permeable membrane to separate ions, unwanted molecules and larger particles from drinking water. Water is forced through these membranes with the use of pressure and force (typically from a pumping system), the usual process of osmosis is reversed via feed water being pushed through the semi-permeable membranes.

One of the most important parts of the Industrial RO system are its membranes , these  are made of spiral wound sheets of semi-permeable material designed to let pure water flow through, while keeping back all other impurities. For water purification in Industries generally the membranes with size of 40 inches length are used and for higher quantities of water membranes with 80 inches are desired. 

Application areas of DOW RO Membrane BW30-365 8040 :

These are industrial membranes and used in larger filtration applications of RO Plants , Demineralization Plants , Municipal Water Treatment etc. With a Pore size of about 0.0001 micron, this excludes most dissolved contaminants while allowing water molecules to pass through it. Reverse Osmosis Process being the most efficient and economical process of filtration has got high acceptability used in industrial applications.
