PRAB EVALED® VACUUM EVAPORATION DECREASE WASHWATER & DETERGENTS COSTS UP TO 75% No air emissions ever! EVALED evaporator technologies operate as a closed loop system under vacuum. Atmospheric evaporators lose valuable energy through air emissions and may require an air permit or waiver for compliant operation. EVALED evaporators have an efficient design with one inlet and two discharge streams- concentrate and distillate. PC- Heat Pump Vacuum Evaporators PC heat pump evaporators offer flexibility, low electrical energy consumption, and superior reliability. • • • Operating pressure of 7-9 kPa...

PRAB EVALED® VACUUM EVAPORATION ACHIEVE ZERO LIQUID DISCHARGE GOALS AC- Hot Water/Cold Water Vacuum Evaporators Reduce operating costs by utilizing excess hot water/steam and cooling water. • • • Operating pressure of 4-30 kPa (0.6-4.4 PSIA) Lower Boiling Temperatures: 30-70 °C (86-158 °F) Single and multiple effect units available Capacities range from 20,000-60,000 L (5,300-15,800 gal) of distillate production per day. Forced circulation reduces scaling, deposits, and fouling. Scraped surfaces allow treatment of precipitating waste streams or crystallization of concentrate to achieve Zero Liquid...

PRAB EVALED® VACUUM EVAPORATION ELIMINATE HAUL-AWAY COSTS RV- Mechanical Vapor Re-compression Engineered for the treatment of large wastewater flow rates with low energy consumption. • • Operating pressure of 60-70 kPa (8.7–10.2 PSIA) Low Boiling Temperatures: 80-90 °C (176–194 °F) Capacities range from 10,000-120,000 L (2,600-31,700 gal) of distillate production per day. Forced circulation reduces scaling, deposits, and fouling. Electrical energy consumption: 30 kWh/ton of distillate (0.11 kWh/gal). Capacities range from 100,000-200,000 L (26,400-52,800 gal) of distillate production per day....
