Physical cleaning is to wash the membrane elements through appropriate pressure and flow, and remove pollutants and sediments attached to the membrane surface in a short time. The key points of cleaning are high flow rate, proper pressure and increasing cleaning frequency.

  First, we use ordinary water guns instead of high-pressure water guns, which are easily damaged Membrane structure parking shed Because of the membrane structure and the shape of the external protective film, the high-pressure water gun should not be used as much as possible. It is difficult to clean the shed. Because it is high, the water gun is generally used for cleaning. First, the water gun is used to clean the surface.

Alkaline detergent is used as the detergent, which may cause damage outside the membrane structure apron. Low pressure flushing frequency ".

  It is recommended to clean the system regularly if conditions permit. It is more effective to increase the cleaning times than to extend the cleaning time. It is recommended to clean it more than once a day. According to the specific situation, the user can specify the cleaning times. Generally, qualified pretreatment water can be used for clean water.
