Can the method of using water to make the filter not blocked? Membrane filtration method, generally, uses a specific semi-permeable membrane, which can only pass through the membrane with water or only pollutants, thus achieving the method of separating pollutants.Homemade sewage filterTools: cups, mineral water bottles, scissors, cloth, crushed stones, sand, soil, tap water, activated carbonSteps1. wrap the bottom of the cut mineral water bottle with a piece of cloth, put a plastic cup under the cloth, and make a simple funnel. It should be noted here that the cloth gap at one end of the mineral water bottle should not be too large. if the gap is large, the cloth can be stacked into two or three layers. Because this cloth is also one of the key factors that can filter.2. Spread the filter material into the container, that is, the mineral water bottle. The first layer on the bottom is paved with a few centimeters thick gravel layer, which is to prevent the sand from flowing out of the bottom of the co

What are the structural principles of precision filter? Precision filter also known as security filter,Usually set before the pressure vessel,To remove fine particles with turbidity above 1 degree,To meet the requirements of the subsequent process for water intake;Sometimes set at the end of the whole water treatment system,Prevent small particles (such as broken resin) from entering the finished water.The shell of the precision filter cylinder is generally made of stainless steel,The inside adopts tubular filter elements such as PP melt spraying, wire burning, folding, titanium filter element, activated carbon filter element, etc,Different filter elements are selected according to different filter media and design processes,To meet the requirements of the water quality.The body can also be installed quickly,Replace the filter element and clean it conveniently and quickly.The equipment is widely used in pharmaceutical, chemical, food, beverage, water treatment, brewing, petroleum, printing and dyeing, env
