Kalebodur invests in new magnetic technology
New evidence indicates lower costs to achieve dine particulate reduction The US EPA has proposed a new ambient air standard for fine particulates which has generated concern relative to the cost for compliance. A new analysis by the Mcllvaine Company shows that power plants could achieve twice the reduction originally estimated, thereby eliminating the need for reduction by smaller sources. Furthermore, the cost borne by the utilities to achieve compliance would not affect the US industrial competitiveness abroad, since other developed nations have already invested in the same equipment which would be required in the US.
Mcllvaine, which has been compiling data on utility air pollution control equipment for 20 years, has been able to make an estimate on a plant-by-plant basis. The EPA is advising states that an economical route to fine particle reduction will be the installation of scrubbers at power plants. Since these scrubbers will remove both the fly ash particles as well as the sulfates, the use of scrubbers will remove up to 90% of 2.8 million tonnes of particles, rather than the 1.6 million tonnes originally estimated. Since the scrubbers are a fixed cost, regardless of the quantity of particulates, the net result is that there is twice the reduction per dollar spent. A detailed analysis of utility emissions is contained in ‘Air pollution management’, published by the Mcllvaine Company. The Mcllvaine Company, 2970 Maria Avenue, Northbrook, IL 60062, USA.

The EPA has calculated utility fine particle emissions of sulfates at 1.5 million tonnes per year. The EPA estimate of fly ash particle emissions is only 99,000 tonnes per year. A Mcllvaine analysis shows actual fly ash particle emissions from utilities at between 700,000 and 2 million tonnes per year. The original EPA estimate was based on general rather than specific information.

alebodur inves magnetic technolo Kalebodur Seramik San AS, part of the Kale Group in Turkey, has purchased and installed a range of magnetic separators from Eriez Magnetics Europe Ltd. The investment was made to reduce the amount of product rejects, and to improve the overall product brightness of its tiles. Kalebodur Seramik is one of the largest tile producers in the world, with a production capacity of 27 million m* of tiles per annum. Its product range includes glazed and unglazed floor tiles and granitor or porcelain tiles. The importance of quality resulted in the company’s investment in Eriez technology. Kalebodur installed a range of Eriez magnetic separators including high-intensity magnetic filters, suspended permanent magnets, rare-earth plate magnets, rare-earth magnetic drums and rareearth magnetic tubes. After detailed technical work between Eriez and Kale, specific designs of magnetic separators were

recommended, depending on the process line. Each magnetic separator was selected to achieve a specific objective, culminating in meeting the overall objective of lower rejects and improved brightness. Kalebodur undertook evaluation on the effects to product quality in its three factories. This assessment took into account all the magnetic equipment installed. The company compared the quality percentage of product and iron defects before and after all the installed magnetic separation. In all three plants the levels of iron defects were halved, and the number of first-quality tiles increased significantiy.

Alan Toms, founder of the Aldershot company, retired in March, but continues in a consultancy capacity. His role as managing director will be taken over by John Lawrence, MD of Hodge Separators. Martin Wheeley, who has several years’ experience at Aldershot, will operate from Penryn, with specific responsibility for the Hodge
Stetfield product range. Hodge Stetfield says the move will enable it to increase efficiencies and enhance its service to customers. The company has gained international recognition as a specialist in the field of industrial oil separation, notably the techniques of tramp oil removal, single and two-stage oil interception for factory and site applications, and ultrafiltration. Dissolved air flotation was added to the range for treating soluble oil waste. Hodge Separators Lid, Jennings Road, Kernick Industrial Estate, Penryn, Cornwall TRIO 9LY, UK.
