Product Description

Multimedia Quartz Sand Filter Sand Media Pressure Filter



 

The Multigrade Sand Filter is a depth filter that makes use of coarse and fine media mixed together in a fixed proportion. This arrangement produces a filter bed with adequate pore dimensions for retaining both large and small suspended particles.
This filter performs at a substantially higher specific flow rate than conventional filters. Specific flow rates of 15-30m/h have been successfully obtained for treating water containing 50-25ppm suspended solids respectively to produce a filtrate with less than 5ppm.

Features :
? Higher specific velocity.
? Raw water can be used for backwashing the filter.

Advantages :
? Higher specific flow rate than conventional down flow filters thereby saving on Space & cost.
? Very little maintenance required.
? Lower backwash water requirement.
? In most cases, raw water can be used for backwash.
Applications :
? The Multigrade sand filters filter is an ideal choice for all applications where a conventional sand filter is used.
? It is extensively used in side stream filtration of cooling water & in potable water treatment.
? It is ideal for filtration of clarified water.
? In addition it finds application in sea water filtration & in filtration of chemical solutions.
? For these types of filtrations rubber lined or epoxy painted filters can be offered.

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.
