ERG to market rotary press

ERG to market rotary press Environmental Resource Group Plc (ERG) has acquired the rights to market the new rotary press, manufactured by Fourier Industries Inc. of Canada. Developed for the dewatering of sludge, the rotary press has undergone extensive trials at a waste water treatment Works in West Sussex, UK.

Low power consumption, small footprint and a final cake with high solids content, gives the rotary press major advantages over conventional dewatering methods, claim its manufacturers. The agreement gives EKG the rights to market the rotary press within the UK and the Republic of Ireland.

A circular chamber contains a number of slowly rotating filtering elements. These elements form channels into which the feed sludge is pumped. The specially designed filtering elements allow liquids to freely drain away whilst retaining any solids. I

Improved stainless steel filter powders developed

‘,

~

MBC Metal Powders, who has been producing stainless steel powders for over 40 years, has developed a new range of high quality filter powders. The breakthrough has been achieved using a high tech proprietary separation technique developed at its Birmingham, UK plant. With conventional melting, even using metal filtration, there is always the possibility of a small number of slag particles entering the atomising stream and carrying over into the final product. A few particles per million of slag in stainless steel filter powders can have deleterious effects on the final product. The new technique eliminates all slag particles with present levels of detection. MBC Metal Powders, Montgomery Street, Birmingham, B17 IDT, UK.

Production scale HPLC system A new production scale High Performance Liquid Chromatography (Prep-HPLC) has been introduced by Prochrom. This system, the LC 300.700.VE.70, is designed to meet both the technical and the economic demands of production scale chromatographic purifications. The column, of 300 mm of internal diameter and capable of operation at pressures up to 70 bar, is equipped with Dynamic Axial Compression (DAC) technology. The maximum bed length is 400 mm, which allows a column volume of 28 litres. Typical capabilities of this system are up to 300 grams per injection. The various modules making up the system (column, solvent, collection and automation) may be customised to meet specific user needs, both from the technical point of view (capacity, flow rates, detection, fraction collection, automation and CIPSIP) as well as from that of safety.
