Multi Media Filtration Drinking water treatment project
Benefits:
More cost-effective with smaller footprint than most membrane filtration or sand filter systems
Minimal use of chemicals
Warranties
Naturally mined media
Low volume of water for backwash
Low whole of life cost
Simple annual maintenance
A beneficial alternative to membrane filtration and cheaper in systems over 6,000 litres per day if underground or 3,000 lpd if above ground
Generally filters suspended solids to 0.5 micron depending on influent.
Fully automated backwash
Integral self cleaning backwash system
Deals with contaminate concentrations of up to 500 mg/litre - filtering to less than 0.5 NTU (officially classified as "ultra-clear")
Plant description
Through the use of automatically controlled backwashing, the filter will operate "on-line" for extended periods of time prior to the short backwashing cycle. Automatic filter operation is monitored on both elapsed time as well as pressure differential. When the controller "calls" for a backwash as a result of pressure differential or elapsed time, the backwashing function utilizes a portion of the clean filtered water produced by the system to clean the media bed. Single tank systems utilize unfiltered water for backwashing. Optional external backwash water sourcing systems are available for both single and multiple tank systems.
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.
