Industrial iron and manganese removal filters that do not require pre-aeration in the water treatment process thanks to the use of a special catalytic medium. The devices can be used in installations with diaphragm tanks. The medium used in the filtration process is regenerated with potassium permanganate.
A central industrial filter for reducing concentration of iron and manganese compounds without water pre-aeration. The Klarsan GS filter removes iron and manganese thanks to the highly effective Greensand Plus catalytic medium. This method is recommended especially for installations with a diaphragm hydrophore tank. The Greensand Plus iron and manganese removal medium requires periodic regeneration with potassium permanganate. The failure-free Clack control valve is responsible for controlling automatic backwash process and regeneration of medium oxidising properties.
