Dixon rings Ranging in size from a quarter to a sixteenth of an inch, Dixon Rings can be packed in their millions into distillation columns, producing an increased surface area for filtration. They have traditionally been used in difficult applications such as removing tritium from water, but specialist filter manufacturer Croft Filters has carried out extensive research, uncovering further uses for them, such as counter- current absorption (also known as scrubbing columns), which scrubs CO 2 from the air or flue gases. Due to advances in technology and automation of many manufacturing processes, Croft Filters states that Dixon Rings are now widely regarded as being superior to other packing options, as they offer an extremely low pressure drop, low height equivalent

to a theoretical plate (HETP) and a large surface area, making them suitable for use in a wide range of applications. Other uses include extracting Galantamine from daffodils, which is used to treat

many industry sectors in the UK and overseas. Working with a wide range of materials, the company’s experts offer consultancy on any aspect of mesh filters, filter elements and filter housings to help meet individual filtration requirements.

Alzheimer’s disease; removing particles or gases from renewable energy production, industrial processes and chemical, medical and hazardous waste processing; and stripping – a physical separation process where harmful contaminants from industrial processes are removed from waste.

Cutting edge technology closes the gap Asset International Ltd, a UK water management solutions company, has made substantial investments in two CNC cutting machines for use in its manufacturing facility in South Wales. The investments will help ensure that Asset, which produces Weholite large diameter plastic pipes, continues to offer safe, efficient and cutting edge productivity. seeks to capitalise on, and consolidate, recent growth. Before making such a large investment, an internal taskforce was set up to establish safer and more efficient methods of working. After identifying specific machines and tools that suited the purpose, they embarked on fact-finding missions to Sweden, Turkey and Germany to ensure that the final investment was sound.

for an extreme level of accuracy and precision. The computer-controlled saw cuts variable angles and curved radii in pipe sizes up to 3m diameter and lengths of over 14m. As well as quality and efficiency improvements, the saw contributes benefits to health and safety, such as elimination of working at height and substantial reductions in exposure to vibration. The CNC gantry miller is a versatile machine that allows endless cutting options and has already allowed Asset to develop new water management products that provide unique solutions for the housing sector. used throughout the water management and construction industries, both in the UK and internationally. Industry sectors include flood defence, housing, sewerage, biogas, drainage, marine solutions, venting, ecological heating and cooling, and engineered SUDS. Weholite products are
