Solids Build Up The centrifugal separators were replaced with two VAF V-500 filters which are effectively maintaining the cooling tower basins in a clean state. This results in a very thorough cleaning of the screen, very low volume of flush waste and minimal loss of chemicals. Over a period of time these surfaces become fouled and insulated causing equipment to run hotter until replacement or repair is necessary. Accounting 248-844-8200 X10 Brentwoods Separator System works in tandem with your chemical treatment program to improve its efficiency, as well as overall tower performance.

In those cases, the separator removes the larger and heavier particles while the filters remove the remaining particulate that pass through the separator. This website requires certain cookies to work and uses other cookies to help you have the best experience. The solution also reduced maintenance and downtime costs while improving thermal efficiency in downstream equipment. The short answer is, normally you dont need a separator. Piston operated screen filters are also known as hydraulic filters and are the lowest cost option for an automatic self-cleaning screen technology. Lets talk purchasing: When specifying and purchasing industrial process cooling equipment, what about an equipment supplier is the most important to you? In general, if you switch the words around you know what a product does. 0000006488 00000 n In this months conclusion, we take a closer look at centrifugal sand separators, piston operated self-cleaning screen filters, and finallywhat is becoming the technology of choice for cooling tower filtration applicationsautomatic self-cleaning screen filters. ,1gU)3`l!at*;TM$Q!

This reduction in cleaning frequency resulted in substantial savings in maintenance costs. Centrifugal separators are cleaned either by purging the particle collection chamber or by allowing a continuous small flow from the collection chamber to a drain. It has all the advantages of drawing C except it does not filter the water before the pump seals. Figure 7: Typical Piston Type Hydraulic Filter Controls The fan on a cooling tower draws in thousands of cubic feet per minute of outside air that contains sand, dust, insects, and fibers from vegetation. 0000033743 00000 n Tower Scour can be spliced into any existing piping system. The primary reason is that the screen filtering element acts as a barrier removing ALL particulate (both organic and inorganic) down to the micron rating of the screen. Debris accumulates in the bottom of the separator until a time-actuated valve at the bottom of the separator opens and the debris is flushed to the sanitary sewer. Cooling towers propel air through water to enhance evaporation. Do You Look For in a Process Cooling Equipment Supplier? 0000014442 00000 n The LAKOS separators now reduce cooling tower problems by about 95%, allowing for a reduction in downtime and maintenance costs. endstream endobj 2112 0 obj <>>>/MarkInfo<>/Metadata 68 0 R/PageLabels 2105 0 R/Pages 2107 0 R/StructTreeRoot 220 0 R/Type/Catalog>> endobj 2113 0 obj <>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/Rotate 0/StructParents 0/TrimBox[0.0 0.0 603.0 783.0]/Type/Page>> endobj 2114 0 obj <>stream The particles become trapped in a water shear layer at the wall of the cylinder and cascade down toward the blowdown at the bottom. This has resulted in a reduction of cooling tower cleaning frequency from six times per year to the minimum Australian standard requirements of two times per year. Photo Gallery Learn More, A General Electric plant in Cleveland, Ohio producing tungsten wire and powder constantly suffered from contaminated, dirty cooling water. H\j >w%PrNReby6l*s)do@q;@. 0000007252 00000 n Also, the hydraulic controls for a piston filter are relatively complex and are inherently problematic, as they can easily empty a cooling tower basin should the unit fail in the open position. Another hotel complex cooling plant comprises of one main system of three common dual cell cooling towers of 7925.16 gallons (30,000 liters) total system volume. Tower Scour removes the solids and supplies a constant, metered blow-down to assure a clean, clear flow with minimum water use. The omnipresent cottonwood seeds and fall fresh leaves will not be filtered. The very basis of heat dissipation employed by a cooling tower is evaporation. 0000036351 00000 n There are hundreds of processes that cooling. hbbd``b`$/ @})IhSX3HX ~ n05 Z"tD6o5NDP#9 _> ,h 0000010630 00000 n With the lower flush volume required to clean the screen, it is much easier to show that none of the flush water is wasted since it is only a small portion of the cooling towers blowdown requirements (see reference 4). Glenn Dobbs is president of VAF Filtration Systems, Arvada, Colorado, and has developed the company into providing state-of-the-art self-cleaning screen filtration products worldwide removing suspended solids down to 10 micron.

If the pump head includes the separator pressure drop, this system can work fine in a constant flow system. Drawing A has the advantage of using the pump pressure coming into it. Meyer, W. Craig. Clean water is discharged up through the center of the separator and back into the system. Thank you for your email!

This problem reduces the piston filters capacity to keep up with the dirt load it is filtering which results in higher flush waste and hence excessive chemical losses. Piston operated self-cleaning screen filters have been around for more than fifty years and were originally founded for low pressure irrigation applications. I show it in a bypass so the separator may be serviced without chilled water shut down. the engineered tangential entry and sloped inlet guide steers the fluid into the SPIREX body where it spins inside the vessel. 0000033393 00000 n ASHRAE and the EPA have both stated that the organic particulate such as algae, combined with the sedimentation that remains in the cooling tower basin after centrifugal separation provide an ideal habitat for bacterial growth such as Legionella (see references 2 and 3).
