Treating Industrial Waste Water With Vacuum Evaporation

The best procedure for effectively separating solid wastes and contaminations from water is the vacuum evaporation technique. Industries that require large or medium flows of water for their productive usage can rely on this indispensable technology that can distill up to 95% of the water with only 5% of rejection. As there is a very high concentration of the residues, the rejection amount is very low. Hence, industries that are in need for huge amount of water for their production causes always prefer to choose this technology for treating the wastes from water. A water treatment plant in Kolkata will offer this water treatment technology for different industries.

Why choose vacuum evaporation?

This water treatment procedure has a range of benefits and they are –

• Distils more than 95% of water, making it reusable
• Minimum waste of water
• Compact and flexible machine design
• Very low power consumption
• Concentration an reduction of liquid residues
• Possible treatment of complex effluents
• Little maintenance and easy to use technology

Suitable application of vacuum evaporation technology:

The vacuum evaporation technology of treating waste water is a highly effective procedure for eliminating the wastes from water. However, it is especially suitable for certain kinds of wastes like –

• Oil emulsions, degreasing water and oily substances
• Dissolved hydrocarbons
• Heavy metals
• Dissolved salts
• Galvanic plating

When the water has these effluents and contamination, it is quite suitable and desired that the industries apply other complementary effluent treatment technologies like physical-chemical processes and membrane filtration to eliminate the initial wastes and make the liquid ready for pre-treatment in the vacuum evaporation technique. With these pre-treatment methods, the further treatments and evaporation techniques are more useful. This will ensure that the concentration is even better.

How to achieve better concentration?

If you are looking for better concentration, the crystallizing technology is always useful. It is done in two ways. In one case, the crystallizer can be used once the vacuum evaporation technique is applied and the other way is the one in which both evaporation and crystallization procedures are done together during the same time. However, using the crystallizers along with the evaporation technique is suitable only when the solution that is being treated is small in volume. It is unsuitable for large volumes of solutions.

When evapo-crystallization procedure is applied, the separate and recuperated product can be sold and reused. For example – the oil that is separated from the oily water can be reused or sold in market.
