Product Description

PRESSURE SAND FILTER multiple layers Graded quartz sand





PRESSURE SAND FILTER PROCESS
Raw water is passed through the pressure sand filter, the filter media is supported on gravel bed that consists of multiple layers of Graded quartz sand, Fine sand, Super fine white sand and pebbles of progressively larger sizes. During the filtration cycle the filter bed retains the dirt and suspended particles from the water and accumulates within the filter the water and accumulates within the filter bed. As the filtration progress the filter media gets loaded with retained suspended particles, this results in a continuous increase of pressure drop across the filter, when a predetermined pressure drop level is achieved the filter is shut down for cleaning.

BACK WASH
As the filtration progress the filter media gets loaded with the retain the suspended particles, this results in a continuous increase of pressure drop across the filter, when a predetermined pressure drop level is achieved the filter is shut down for cleaning. The filter media is cleaned by backwash system. After backwashing the filter is rinsed with raw water and after the required quality of water is achieved the filter is put back into service. Depending on the filtered water quality required backwashing is either done with raw water or with filtered water.







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.
