Multi Grade Sand Filter 20 to 30 Microns Water Filtration
Multi Grade Sand Filter offered by us consist of a vertical/ horizontal pressure vessels with a set of frontal pipe work & valves. The media consists of different sizes & grades mixed and supported by layers of pebbles and gravels. It also features a top distributor for achieving effective distribution of the incoming water uniformly throughout the cross section of the multi grade sand filter and an under drain system for collecting filtered water.
The basic difference between Pressure Sand Filter (PSF) & Multi grade Sand Filter (MGF) are media used in vessel and velocity variation. Multi grade sand filters perform at a substantially higher specific flow rate than conventional filters.

Working principle:
For the by-pass filtration, the filter is installed in the main circulating pipeline to filter all the circulating water,
but apart of the circulating water led from the main circulating pipeline is filtered, which is a repeated
circulatininterception step by step to filter the impurities within the system and finally remove the impurities
by thenecessary backwash out of the system. Installing a by-pass filter in the circulating water system can
prevent the terminal pipe of device from sludge blocking and remove the impurities in the system with
chemical dosing.
By-pass filtration is used to reduce the turbidity of the water circulation system, exactly, to reduce slime
and
prevent its deposition in the heat exchanger, so that the effect of agent will be better.
Generally speaking, if your filter is a quartz sand filter, it usually has two main functions:
1. To reduce suspended solids (turbidity). Otherwise, as the system is running, suspended solids increases
, which will exacerbate the deposition and other problems.
2. Degreasing. Especially the oily turbid circulation, such as steel rolling and continuous casting, has high
oil content and is easy for breeding microorganism and blocking the nozzles.
