G) Easy operating & maintenance




Working principle:


For the Pressure Sand Filter, 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.

Pressure Sand Filteris 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 Pressure 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.
