With the development of society, the requirements for waste disposal are higher and higher. Wastewater evaporation technology becomes the main method for wastewater treatment.
In the wastewater evaporation process, the effluent boils at low temperature under vacuum and it may be solid-liquid mixture or liquid containing particles, which require high-quality plastic valves. KOSCN MV300, 303 series pneumatic diaphragm valves are designed to eliminate leakages, suitable for vacuum work environment and transportation of media of solid-liquid mixture or media containing particles. KOSCN plastic valves provide solutions to the vacuum evaporation wastewater system from feed and transportation of effluents to discharge of distillate. During the whole process, the constitution of the effluent is changing all the time and it may contain fluorine, phosphorus, solid impurities, and particles, etc. which may be corrosive and require the valves have outstanding sealing performance. KOSCN industrial valves are competent to the wastewater treatment process in following industries:

• Electroplating: eluted fluids of resins plants, fluids from chrome, nickel, and copper washing
• Mechanical: oily emulsions, washing fluids
• Garbage fluids
• Fluids from bleach plants
• Reverse osmosis
• ZLD: total recycle of waste water
