vacuum evaporation

NATURE HAS GUIDED US TO DEVELOP OUR TECHNOLOGY:

Waste management by low temperature distillation developed by ZEWATECH is based on the natural physical phenomenon of evaporation with a great optimization of the whole process to achieve a REDUCED ENERGY CONSUMPTION

TECHNICAL BASIS ZEWATECH

The vacuum evaporators transform a residual industrial effluent into two currents:

A) One corresponding to the high quality totally purified distillate which can be reused and re-circulated in the production process of the desired product of each company in specific or used for another purpose but completing a circular economy.

B) On the other hand, a concentrated waste or a solid waste is also generated which significantly reduces the costs of waste management and treatment.    In other applications this waste is used as CONCENTRATE for reuse

ZEWATECH TECHNOLOGY HIGH PRODUCTION PERFORMANCE

It is the most effective technology in terms of the minimization and treatment of liquid industrial waste with an aqueous base. This technology from vacuum evaporation is clean, safe and versatile as it adapts to any situation and industry.

A vacuum evaporator is powered by electric energy or other alternatives such as thermal oil, steam, hot water, etc. The Standard ZEWATECH equipment uses the technology of heat pump and steam thermocompression to distill waste at a low energy cost.

The main reason why evaporators represent an important technological advance is that through vacuum pumps, a vacuum of 33 mbares is carried out in the installation and this allows the desired product to boil at a temperature of approximately 31ºC. Boiling effluents at this temperature not only allows evaporation without a very high energy cost but also the water after condensate has high quality properties and in most cases is reusable in many functions.

The product (0) enters the evaporator and is deposited in the boiling chamber (1) where the temperature increase begins, at the same time, the vacuum pump (3) as its name indicates, reduces the pressure of the evaporator.

Once the bubble temperature has been obtained, evaporation begins. The gas particles of the treated effluent travel through the condensation chamber (2) and are extracted by means of an injector (4) in a distillate accumulator (5) which is finally where the desired product is and the distillate is extracted (6).

On the other hand, a heat exchanger (7) and a generator (8) are used to maintain the high internal temperature and the temperature of the refrigerated condensation chamber.

The equipment at all times is controlled by pressure gauges to have control of the pressure at all times as it is the most important part of this operation.

At the bottom of the exchanger is obtained the concentrate or dry residue in many cases (9).
