Analiza niezawodności działania stacji uzdatniania wody (SUW) wykorzystuja̧cych techniki membranowe

Four com. membrane water treatment plants were analyzed for their operability and reliability. The reverse osmosis-based plants for purifn. of drinking water consists of coagulation with FeCl₃, flocculation, neutralization with HCl, two-stage filtration, two-stage permeation and disinfection with ClO₂ (capacity 40 m³/h). Another plant for mine water treatment based on reverse osmosis yields drinking water with a capacity 800 m³/d. The microfiltration-based water treatment plant is used for purifn. of mine water used for techn. purposes. It includes oxidn. of crude water with KMnO₄, disinfection with NaOCl and cleaning the capillary membranes with an air stream. Another plant uses microfiltration for purifn. of river water delivered as drinking water after addn. disinfection with NaOCl.
