Fuel polishing system filters out water and dirt
Reverso Pumps Inc’s newly designed FPS-150DC fuel polishing system features highefficiency Racor filters to separate water from fuel on both recreational and commercial boats. By eliminating water and dirt, the fuel polishing system improves engine operation and fuel system efficiency, claims the company, which is based in Fort Lauderdale, Florida, USA. The unit’s Racor turbine filter removes 100% of water and any algae build-up in fuel tanks, to keep diesel fuel clean and reliable. With a high-capacity Racor Aqua Block II element, the filter processes 568 litres of fluid an hour. Monitored by a built-in vacuum gauge, use of the filter element can reduce maintenance costs. For additional treatment, an optional magnetic fuel conditioner is also available. To deal with the harsh marine environment, the fuel polishing system is constructed from powder-coated metal. The unit features a brass pump body, bronze gears and a stainless steel shaft. Equipped with a six-hour timer, it is easy to use and operate, says the company.
Particle filtration is carried out at high flux-rates US company Dynaflow Inc has introduced a system that is designed for enhanced, high fluxrate filtration of particles from liquids. Called Dynaperm, it is based on cross-flow microfiltration, and uses thick-walled microporous plastic tubes. The pore-size range and structure is controlled during manufacturing. The tubes, made from a variety of thermoplastics, are rugged, and chemically and biologically inert.
Dynaperm increases the flux rate and economy of particle removal from liquid by combining features of cyclone separation, flow interruption and cross-flow filtration. This almost completely removes suspended particles down to a micron in size. Laboratory experiments conducted with the system have produced flux rate increases of a factor of 50 over conventional crossflow filtration with comparable or improved effluent
quality, claims the company, which is based in Jessup, Maryland, USA. Applications include stream and effluent treatment roles such as pretreatment for suspended solids removal before reverse osmosis, carbon adsorption, or ion exchange; polishing, for removing fine suspended solids after chemical or biological treatment; and valuable materials recovery and dewatering.
