EVALED PC - 2

The EVALED™ PC Solution is the range of evaporators which uses heat pump for the treatment of many kind of waste waters. This technology has been refined over many years in terms of flexibility low energy consumption and Main benefits of heat pump: © Significant reduction of COD in the distillate © High yield and and low quantity of © Excellent separation of surfactants ©Total separation of metals ©Consistent distillate quality © Fully automatic operation The battle against the climate change is a priority VWS Italia has a real commitment to reduce C02 emissions: we are working to make sure...

EVALED PC - 3

VWS Italia, in co-operation with respected materials research centres, selects the most suitable materials for the safe management of aggressive liquids. The resistance to corrosion is the main features of every EVALED™ evaporators, essential when dealing with extremely concentrated liquids. Austenic stainless steel AISI 316L Austenic weakly bound structure, non-hardening, non-magnetic. The low percentage of Carbon in this alloy reduces the risk of intergranular corrosion at high temperatures. Uses: alkaline liquids, acid liquids (pH>4) with a low percentage of chlorides, oil emulsions,...

EVALED PC - 4

E series is designed to produce maximum distillate quality with minimum capital and operating costs. Each model is a compact skid-mounted unit, simple, safe and easy to move. Control is by a PLC, including the functions of feed and discharge, therefore allowing automatic operation and minimum supervision. All models are designed for continuous operation, 24hs/day, and require just an electrical supply and compressed air. E series evaporators operate in a high vacuum condition, with the boiling chamber pressure set at 5-6 kPa (absolute), in order to save the thermal energy produced by the...

In the R series the exchanger of heat is via a conical jacket at the base of the boiling chamber, while the inner heating surface is continuously cleaned by scrapers, which also act to stir the concentrate. This configuration is designed to produce a concentrate with a high final concentration and a distillate R Series is particularly suitable where: © the waste water has a high initial content of dissolved or suspended solids © the waste water is already pre-concentrated © the daily volumes are relatively small © the distillate has to be of the highest quality R Series is is the best...
