Cooling Tower Side Stream Filtration Calculation

Recirculating cooling water systems often experience sludge and solid build up.

Cooling tower side stream filtration calculation.

Sidestream filtration as the name suggests refers to the partial filtering of liquid in a system. The basin water inventory may only be filtered and or side stream filters may be employed at the discharge of the cw recirculation pumps. Make up water source is high in suspended solids iron biological and organic activity. The evaluation provides a characterization of side stream filtration technology describes typical applications and details specific types of filtration technology.

System economics are also discussed providing an example project with life cycle. This method involves removing particles at a higher rate than accumulation. 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. Vortisand filters can be used anywhere media filtration is considered.

Due to its outstanding ability to remove submicron particles vortisand filters are especially prized as a pretreatment step for reverse osmosis seawater desalination or ultrapure water production as a side stream filter cooling towers chilled and hot water loops or as a polishing filter after secondary clarifiers or. 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. 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. 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. Modern day cooling tower systems have thus adopted side stream filtration of the water from the cooling tower. 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. 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.

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. Side stream filtration is an effective tool for the control of deposition and fouling in a cooling water system. 6 signs your cooling tower requires a side stream filtration consider the following signs your facility requires a side stream filtration system. Various schemes can be implemented.

Determining the proper type for your system includes examining various factors and filter media types. Choosing the right filtration side stream filtration system can yield significant savings.
