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.
