Three Backwashing Knowledge of Sprinkler Irrigation Belt
Sprinkler belt is an indispensable device in medium pipeline. It is usually installed at the inlet of pressure relief valve, pressure relief valve, constant water level valve or other equipment to eliminate impurities in the medium to protect the normal use of valves and equipment. You may not know much about its backwashing. Here are three backwashing knowledge for you.
1. In the process of sprinkler irrigation belt filtration, suspended substances in water accumulate continuously through the adsorption of filter layer. Finally, filter cake is formed on the surface of filter layer, and the loss of filter head is increasing, so backwashing is needed.
2. Water quality deteriorates due to head loss, so it is necessary to clean the filter material in order to restore the ability of the filter material layer to absorb pollutants.
3. Sewage contains a lot of suspended substances. Long-term residence in the filter will lead to a large number of bacteria, which need to be cleaned regularly.
