Design principle and composition of the media filter
- Aug 18, 2018 -

A media filter is a device that uses one or several filter media to pass a turbidity water to a certain thickness of granular or non-granular material under a certain pressure, thereby effectively removing suspended impurities and clarifying water. Water treatment removes turbidity, softened water, pre-treatment of pure water, etc., and the effluent turbidity can reach below 3 degrees.


The medium filter is mainly composed of a filter body, an auxiliary pipeline and a valve, wherein the filter body mainly comprises the following components: a simplified body; a water distribution component; a support component; a backwashing pipe; a filter material; an exhaust valve. The filter materials commonly used in the medium filter are quartz sand, anthracite, manganese sand, etc., through which the medium filter can be used in the industrial circulating water treatment system to remove impurities in the sewage, adsorb oil, etc., so that the water quality conforms to the recycling. Claim.


In the filter material of the medium filter, the pebbles mainly play a supporting role. During the filtration process, because of its high strength, the gap between the gaps is stable, and the pores are large, which facilitates the smooth passage of the filtered water during the washing process; Similarly, in the backwashing process, backwashing and backwashing air can pass smoothly. In the conventional configuration, the pebbles are divided into four specifications, and the paving method is from the bottom to the top first and then small.
