250m3 /H Partial Stream Filtration Multimedia Filter

250m3/h partial stream filtration multimedia filter pharmaceutical



Cooling water
 
Cooling systems are divided into three types:
 
Once-through systems
Closed loop systems 
Open loop systems
Open loop systems are the most widely used system and examples of this are cooling towers and evaporative condensers. At the same time, water treatment is most prevalent in connection with open loop systems. Water treatment is carried out in order to minimize scaling and deposits, fouling, corrosion, and biological growth.
 
Complete solutions
An optimum cooling water solution is achieved by continous drainage of correct water volume, softening of make-up water, partial stream filtration, and correct dosing of polyphosphate and hypochlorite respectively. 
 
Optimum economy
A correct treatment of cooling water gives optimum service conditions and extends the life of the cooling system significantly.

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.
