Automatic Backwash Multimedia Quartz Sand Filtration for Water Treatment

Product Description

Automatic Backwash Multimedia Quartz Sand Filtration For Water Treatment
Automatic Backwash Bypass Sand Filter is consisted of a filtration system and a control system. Filtration system generally consists of the filter unit, three automatic valves, import and export pipeline, sewage pipeline. The filter unit includes a filter medium. Control system usually consists of PLC timing controller, differential pressure controller, and electromagnetic three-way valve.

Automatic Backwash Bypass Sand Filter is a high efficiency filter, It can effectively remove the suspended substance, microorganisms, and other fine particles in water. Ultimately achieve to reduce water turbidity, purify water quality.


Used in the treatment process, mainly for turbidity water treatment, reverse osmosis, and pretreatment preparation of ion exchange softening desalination system


Also used for sediment removal of surface water and underground water. Inlet turbidity less than 20 degrees, the outlet turbidity up to 3 degrees below.


It can be widely used in electronic power, petrochemical, metallurgy electroplating, paper textiles, pharmaceuticals dialysis, food and beverages, drinking water, factories and enterprises water, swimming pool. It also can meet the needs of liquid filtration in various industries

Advantages:
Multi-media carbon/sand filter tank in water treatment
A) High filtration efficiency.
B) Low resistance, high capacity, high sewage interception capability, long service life.
C) High cleanness of filter and no pollution of filtering media.
D) Anti acid-base.
E) High strength, high temperature resistant, no deformation.
F) Low purchasing cost and operation cost, easy to clean and replace filter cartridge.
G) Easy operating & maintenance
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.
