RevoTec Reverse Osmosis

REVOTEC produces demineralized water perfectly suited for beverages, as boiler feed water and for treatment in subsequent purification steps. If a semipermeable membrane is placed between pure water and water with dissolved ions (salts) osmosis will come into play.



Technical Description – RevoTec

Reverse Osmosis

The reverse osmosis system REVOTEC produces demineralized water that is perfectly suited for manufacturing of beer and beer-based mixed drinks. Considering the quality of the raw water, the unit is designed individually for each specific application.

A Closer Look

Reverse osmosis (RO) is the reversal of natural osmosis. If a semipermeable membrane is placed between pure water and water with dissolved ions (salts) osmosis will come into play. The pores of the membrane only allow the passage of H2O, but not of salts, suspended solids, bacteria and larger molecules. Osmotic pressure due to a concentration difference on both sides of the membrane causes the pure water to pass through the membrane to dilute the solution on the impure side. This will continue until osmotic equilibrium (the same concentration on both sides) is reached. In the REVOTEC unit this process is reversed. To separate pure water from water containing dissolved salts and solids, pressure is applied to the contaminated water. When the applied pressure overcomes the natural osmotic pressure, pure water will pass through the membrane into the pure water side. The purified water (permeate) is practically free of all impurities. This crossflow technology minimizes fouling of membrane elements by quickly removing the impure water (concentrate). However, depending on the contamination of the raw water, pre-treatment may be required to prevent scaling and chemical attack from oxidizing agents like chlorine. To exactly reach the desired water quality and to increase the capacity of the system, permeate can be blended with raw water.
