Cooling Tower Filtration Rate

Keep in mind the filtration rate will highly depend on the application and filtration technology at hand.

Cooling tower filtration rate.

Stream filtration for cooling towers. 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. Current flow rate and total daily flow up to 63 days which is useful in determining how many times system volume has turned over along with many other. The evaluation provides a characterization of side stream filtration technology describes typical applications and details specific types of filtration technology.

Cooling tower water filtration and basin cleaning systems lcf filtration systems have a small footprint and are available with flow rates from 11 to 334 m hr 50 to 150 gpm. Featured in process cooling magazine. Various schemes can be implemented. Modern day cooling tower systems have thus adopted side stream filtration of the water from the cooling tower.

Almost all process cooling systems involve water which over time accumulates dust sand pollen algae and pipe scale particles that originate from cooling towers and makeup water. An important design criterion is sufficient screen area to handle varying water quality. Full flow cooling tower filtration drastically reduces heat exchanger and chiller upkeep and improves the overall operation of equipment. This method involves removing particles at a higher rate than accumulation.

Plant engineers discovered that the small 400 gpm side stream four bag filtration system on their 5 300 gpm cooling tower system did not provide the protection they needed for heat exchangers condensers vessel cooling jackets and an 800 ton chiller. Why do cooling towers require filtration. At worst they can degrade system heat transfer capacity and lead to steep increase in dosing rate and consequently the cost of water treatment chemicals e g bactericides. Over time filtering 1 10 of the cooling loop flow results in the filtration of the total volume of water every 12 72 hours.

In order to achieve full flow cooling tower filtration it follows that a system flow rate of 500 gpm requires a filter sized to treat 500 gpm. Ameriwater high efficiency filters are much more efficient at removing the extremely fine particles that cooling towers scrub from the air. System economics are also discussed providing an example project with life cycle. Not only do filtration efficiencies improve dramatically but the filters require up to 10 times less backwash water.

Benefits of cooling tower filtraton cooling towers are excellent air scrubbers.
