Cooling Tower Side Stream Filtration Calculation
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.
Cooling tower side stream filtration calculation. Side stream filtration is an effective tool for the control of deposition and fouling in a cooling water system. 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. System economics are also discussed providing an example project with life cycle. 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.
The technology evaluation assesses side stream filtration for cooling towers. What is sidestream filtration. Determining the proper type for your system includes examining various factors and filter media types. Recirculating cooling water systems often experience sludge and solid build up.
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. 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. In cooling water systems sidestream filtration is generally sized on 5 10 of the total cooling tower water flow rate. Make up water source is high in suspended solids iron biological and organic activity.
Various schemes can be implemented. Benefits of side stream and media filtration in cooling towers. The basin water inventory may only be filtered and or side stream filters may be employed at the discharge of the cw recirculation pumps. The evaluation provides a characterization of side stream filtration technology describes typical applications and details specific types of filtration technology.
6 signs your cooling tower requires a side stream filtration consider the following signs your facility requires a side stream filtration system. Sidestream filtration as the name suggests refers to the partial filtering of liquid in a system. Modern day cooling tower systems have thus adopted side stream filtration of the water from the cooling tower. Choosing the right filtration side stream filtration system can yield significant savings.
Vortisand filters can be used anywhere media filtration is considered. 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.
