EVALED - Evaporator - Veolia Water Technologies Italia Spa products

PC R series evaporators combine the versatility of heat pump technology with the effectiveness of the scraping system installed inside the boiling chamber. The combination of these two technological solutions therefore allows the treatment of wastewater at low temperatures (max. 40° C), offering the opportunity to achieve high degrees of concentration. Scraped evaporators with heat pump and forced circulation.

The AC R and AC S series evaporators are designed for wastewater treatment and offer the highest level of concentration and solids separation in the entire EVALED range. The models in these series add an internal surface scraping system (auger or oscillating depending on the model) to the effectiveness of low-temperature evaporation provided by the vacuum condition in the boiler, that enables to obtain a semi-solid final concentrate with a dry matter content higher than 75%.

The RV F series is the EVALED range of evaporators designed to offer maximum reliability in heat transfer while minimizing fouling and scaling. The application of mechanical vapor recompression technology is the basis of the reduced energy consumption that distinguishes this line of evaporators from other technologies on the market. Calories and refrigerants needed to heat and cool the inlet and outlet streams are in fact provided by the treated liquid, allowing a specific electricity consumption of only 35 - 45 kWh/ton. Evaporators with mechanical vapor recompression and forced circulation.

EVALED evaporators in the RV N series are specifically designed for the treatment of oil-containing wastewater and are the ideal product line for the treatment of oily emulsions typical of the mechanical engineering and surface treatment industries. Evaporators with mechanical vapour recompression and natural circulation.
