Thanks to mechanical cleaning, suspended particles in the form of rust, lime, sand, clay, and other mechanical impurities are removed from the water. From the efficiency of mechanical filtration, depends the quality of further purification.
By the way of filtration, mechanical filters can be divided into:
More rational to use reticular, or more precisely, reticular drum filters.
The main part of this type of filter is a hollow drum with reticular filter elements attached to hi surface. Processed water enters through the inlet pipe into the drum and, passing through the reticular, leaves some of the contaminants on them. The clarified water is collected in the chamber in which the drum is located. And sent further to the relevant facilities.
To avoid rupture of the reticular from excessive water pressure on them and maintain the operability of this aggregate, it is necessary to stabilize the water level in the chamber with a reticulated drum filter. This can be achieved with the help of an overflow wall, which is installed in the end part of the chamber.
Advantages of this filter:
The chemical method of water purification is carried out thanks to chemical reagents, which are very harmless to the human body and other living creatures. However, when the ratio of pluses and minuses, does not give up their positions.
When cleaning wastewater, the most important thing is to organize the chemical reagents correctly in water. This will require a high-quality laboratory analysis of water and impurities in it. Such an analysis will accurately determine the dosage.
There are two main methods of chemical water treatment:
In general, chemical wastewater treatment is quite effective and ensures compliance with sanitary standards, and this is an additional opportunity to reuse purified effluent and thereby save water resources.
