Working principle of mechanical filter:

When the water contains 5-10mg / 1 iron and 1mg / 1 manganese, single-stage treatment is adopted: water oxygenator and water tank pump Single-stage filter water tower. If the content of iron and manganese is higher than the above concentration, it is only necessary to change the single-stage filter to the double-stage filter. If the pH value and alkalinity of the raw water are low, lime milk can be added in the oxygen filling process.

During the initial operation of the equipment, the backwash water volume is not easy to be too large, so as to avoid affecting the formation of biofilm. Equipment working pressure ≤ 0.4MPa, working 25 ℃.
