S uDS supplier SDS Limited has entered into a partnership with o -site build specialist Asset International to step up UK manufacturing of sustainable drainage systems in response to demand. Increasing local authority planning requirements for compliant sustainable drain- age systems (SuDS) in major developments is boosting de- mand for water quality treat- ment components, prompt- ing supplier SDS Limited to establish a UK manufacturing base to service its growing order book. Increasing sales of the SDS Aqua-Swirl hydrodynamic vor- tex separator, used to remove polluting silts and sediments from surface water runo as part of SuDS, have prompted a new partnership between SDS and the o -site build specialist Asset International. The innovative technol- ogy of the Aqua-Swirl was introduced by SDS to the UK market in 2015 and its new sis- ter high-performance † ltration system the Aqua-Filter was added to its range last year. Production of both devices has already begun at Asset's plant in Newport, using Weholite HDPE components, and the † rst products have been deliv- ered to site. The arrangement has more than halved the delivery times to SDS customers as well as providing more opportunity to engineer bespoke components to meet the precise require- ments of a drainage design. 30 | NOVEMBER 2018 | WWT | www.wwtonline.co.uk The Knowledge Supplier News W igan-based CPL Activated Carbons has dramatically increased its capacity for reactivating 'amber list' spent carbons from industrial puri- † cation processes, following a major expansion at its Im- mingham production facility. Activated carbons are used in a wide range of gas and liquid phase † ltration applica- tions, such as air treatment, water puri† cation and numer- ous other environmental protection applications. When carbons are 'spent' and no longer achieving the required level of † ltration, they need to be replaced. In most cases, spent carbons can be regen- erated by a process called thermal reactivation, which involves passing the spent media through a high tempera- CPL trebles carbon reactivation capacity A team from Cran- † eld University who developed the Nano Membrane Toilet has been recognised with two awards at the 2018 International Water Association (IWA) Project In- novation Awards in Tokyo. The Cran† eld team picked up the Kiran and Pallavi Patel Grand Innovation Award, presented to an outstanding example of innovation in the water sector, as well as the Gold award in the 'Break- throughs in Research and Development' category. The Nano Membrane Toilet is being developed in response to the Bill & Melinda Gates Founda- tion's 'Reinvent the Toilet Challenge'. The challenge was to develop a toilet that pro- vides a safe sani- tation solution for the develop- ing world, at minimal cost to the user. Many areas that lack access to this basic need are also those with non-existent or unreliable water, sewage and electricity supplies. Cran† eld's solution is able to treat human waste on-site without external energy or water, allowing it to be safely transported away and poten- tially reused. Dr Alison Parker, lecturer in International Water and Sanitation at Cran† eld Univer- sity, said: "We are absolutely delighted to be recognised in this way and it is a credit to everyone who is working on the project." Cranfi eld team win award for Nano Membrane Toilet rotary kiln at the Immingham site. The kiln, which is the largest 'amber list' regenera- tion facility in the UK, and one of the largest in Europe, has a sophisticated thermal oxidiser and scrubber system to ensure full environmental protection and compliance. ture rotary kiln to restore its † ltration capability. Spent activated carbons from the various puri† cation applications are generally cat- egorised into two broad types, which dictates how they are subsequently handled and re- processed. Spent carbons from industrial applications such as air and biogas † ltration, waste water and remediation projects are referred to as 'amber list' materials. Carbons that have been used in drinking water or food grade applications are referred to as 'green list' materials. CPL's carbon regenera- tion facility is located at the group's UK manufacturing site in Immingham, Lincolnshire, where it has been successfully reactivating 'amber list' spent carbon † ltration media from industry since 2013. Following a major invest- ment by the parent organi- sation, CPL Industries, the company has dramatically increased its capacity for treat- ing these 'amber list' spent carbons, with the installation of a brand-new, state-of-the-art Development' category.
