Tekleen filters are self-cleaning Automatic water filter specialist Tekleen has developed the LPF series of fully automatic selfcleaning water filters. The range has a working pressure as low as 15 psi and features Tekrinse screen cleaning technology, which can save up to 90% of rinse water. The filters range from 1 inch to
36 inch line size and can filter down to 2 microns. Tekleen water filters are suitable for a variety of plastic processing applications including extrusion lines, spray nozzle protection, mould cooling water, chiller water and utility water. www.tekleen.com
Dow film technology used in Mongolian treatment plant Dow Water & Process Solutions’ film technology will be used in the treatment of water at the Ordos Dalate municipal drinking water treatment plant, in Inner Mongolia, China. The plant, which cost a total investment of RMB270 million, is located in the Dalateqi of Ordos, covering an area of approximately 200 acres. Starting construction in 2009, it is a supporting project of the 200,000-ton central urban water supply project built by Ordos to meet demand in the Dongsheng District. At present, drinking water supplied daily by phase I of this plant is 100,000 m3 and after completion, the plant will become the main drinking water supplier for the one million population in Ordos’s central urban area. The plant has adopted the latest model of Dow’s ultrafiltration film module Ultrafiltration DOW SFP-2880 and nanofiltration film module FILMTEC Nanofiltration NF90-400 to purify local underground raw water resources containing traces of pollutants. The capacity of the two modules can reach 5,396 m3/hr and 2,083 m3/hr respectively. The two sets work together in order to reach the best filtration and purification effects. By assistance of the traditional coagulation filtration technology, precipitation filtration technology and granular activated carbon filtration technology, safe and reliable drinking water is guaranteed for
local residents. Through this series of filtration processes, the quality of water from the plant has already completely reached the Hygiene Standards of Drinking Water (GB5749-2006) issued latest by the country. In recent years, Ordos of Inner Mongolia has already become one of the prefecture-level cities with the fastest growth in China. Due to its location in the deep desert hinterland of Inner Mongolia and lack of rain throughout the year, Ordos faces severe water shortages. Before the rise of the coal and chemical economy, local economic development was relatively slow, leading to a backward infrastructure. With the rapid economic development of Ordos, there has been a substantial increase in the life quality of local residents, which also raised the requirements on the quality of drinking water. “Dow feels proud of being able to provide advanced and quality technical support of ultrafiltration and nanofiltration to this project that brings benefit to people,” said Dr. Wang Xiaolan, commercial director of the Asia-Pacific region, Dow Water & Process Solutions. “We will provide clean and safe drinking water through advanced water purification technology. To help Chinese residents enjoying a healthier life is the objective that the enterprise strives for.” www.dow.com
Cyclone specialist formed A new US company, Heumann Environmental Co has been established to design and build cyclones to separate microscopic particles from gas streams. Heumann Environmental Co.’s (HEC) main applications will be industrial processing, recovery and pollution control applications in a variety of industries including pharmaceuticals, petrochemicals, wood products and utilities. Besides the cyclone technology, HEC will also provide scrubber, filter and electrostatic precipitator (ESP) equipment. Industry expert, company founder and CEO William L. Heumann who previously worked at another environmental services company, says HEC was formed to address the most vexing particle/gas separation challenges. “Maximising process efficiency,
and doing so quickly and efficiently, provides the greatest value to customers,” he said. “We are here to solve problems, assembling knowledgeable teams, and recommending and manufacturing equipment as needed to custom engineered solutions.” The company can develop entirely new systems for new industrial operations, or analyse existing industrial systems to determine the causes of underperformance and recommend actions to optimise processes. It also provides troubleshooting and optimisation, balanced air ventilation system design, fluid bed system design, aerodynamic particle size analysis (liquid sedimentation), pilot testing education and technical resources. www.heumannenviro.com
Cummins Filtration releases new fuel filter Cummins Filtration, a division of Cummins Inc., has introduced the Fleetguard® FF5782 fuel filter with nanotechnology-based filtration media. The company says that this is the first of its kind for fuel filtration. The FF5782 was developed specifically to meet the high-performance demands of Cummins QSK high-horsepower engines. With field-testing over a threeyear development cycle, this latest in the Fleetguard fuel product line has been developed to deliver protection and improved uptime for customers. Trapping 98.7% of all particles as small as 4 microns, the FF5782 exhibits 13 times greater retention of particles during fuel surge and engine vibration than its closest competitor, claims Cummins. Fuel surge results from the fluctuation of fuel flow due to the increase and decrease in the engine output. Focused on reducing injector failure by removing harmful
particles and by delivering fuel that meets Fuel Injection Equipment (FIE) manufacturers’ suggested ISO 12/9/6 cleanliness level, engines equipped with the FF5782 fuel filter showed no signs of injector wear after more than 190 hours of testing. An engine in identical condition, using standard fuel filters, showed significant wear after only 50 hours, ultimately leading to premature injector failure. “The most important and expensive component in today’s high-pressure common-rail fuel system is the injector. Hard particles in the fuel flow can cause significant wear, disrupting its precise operation, reducing fuel efficiency and leading to premature injector replacement,” said Kevin Westerson, chief technical officer, Cummins Filtration. “Our FF5782 fuel filter with nanotechnology-based media protects up to 13 times better than its predecessor, so injectors work better, longer.” www.cumminsfiltration.com
