Determining the proper type for your system includes examining various factors and filter media types.
Cooling tower side stream filtration calculation.
The basin water inventory may only be filtered and or side stream filters may be employed at the discharge of the cw recirculation pumps.
Filtered water is then pumped back into the main condenser line through a nozzle or re turned to the cooling tower basin called the sump.
System economics are also discussed providing an example project with life cycle.
In cooling water systems sidestream filtration is generally sized on 5 10 of the total cooling tower water flow rate.
For example if the total flow of a system is 1 200 gal min a 400 ton system a sidestream filter with a 120 gal min capacity is specified.
Modern day cooling tower systems have thus adopted side stream filtration of the water from the cooling tower.
Make up water source is high in suspended solids iron biological and organic activity.
Many engineers size the system to continuously filter the cooling tower basin water at a rate equivalent to 10 of the total circulation flow rate.
Sidestream filtration as the name suggests refers to the partial filtering of liquid in a system.
Benefits of side stream and media filtration in cooling towers.
Choosing the right filtration side stream filtration system can yield significant savings.
Properly sizing a side stream filtration system is critical to obtain satisfactory filter performance but there is some debate over how to properly size the side stream system.
Various schemes can be implemented.
It is typical to size the side stream filter to continuously filter the cooling tower basin water at a rate equivalent to 10 of the total circulation flow rate.
The evaluation provides a characterization of side stream filtration technology describes typical applications and details specific types of filtration technology.
Cooling tower with side stream filtration examples technology characterization side stream filtration systems continu ously filter a portion of cooling water to remove debris and particles.
The technology evaluation assesses side stream filtration for cooling towers.
Vortisand filters can be used anywhere media filtration is considered.
Recirculating cooling water systems often experience sludge and solid build up.
Side stream filtration is an effective tool for the control of deposition and fouling in a cooling water system.
What is sidestream filtration.
The water is pumped from the cooling tower cold water basin through the side stream filtration system into the heat exchangers and chillers and then returned back to the cooling tower basin.
