Water & Wastewater Treatment

The Ovivo® screw compactor incorporates the original Jones+A wood™ features that have a proven record of reliability and robustness. Our new design now receives flows from water powered launders and incorporates a 9mm thick drainage trough for ruggedness and 6mm TAPERED holes for improved drainage– built with lowering TOTEX in mind. Available in 5 standard sizes the Ovivo screw compactor loading capacity ranges between 0.5 and 9.5 (M³/Hr) and launder flows up to 8.0l/s.

"Our focus has been on biological treatment – nurturing of and separation of that biology. These systems take energy and much of our R&D ef- forts are looking at applying different technologies at a wastewater treatment plant to make it energy neutral." "We are extremely ex- cited by the prospect of pro- viding systems that generate enough electricity to run themselves. We are focusing on the future and reducing clients' operational costs by installing pieces of the puz- zle that will allow them to be energy neutral." "The newest product RESEARCH ROUND UP Early Career Researcher prize Swig is running its biennial Early Career Researcher Prize 2014. The shortlisted post- ers will be displayed at the WWEM Conference on 5-6 No- vember 2014. The first prize of £1,000 will be presented at a dinner at the confer- ence on 5 November 2014. "Swig invites students and employees involved in the field of water sensor research to design a scientific poster summarising their work. This is an opportunity for re- searchers within the water and environmental sectors to showcase their work," says Swig. The Swig Early Career Researcher Prize is open to under-graduates and post- graduates in full-time educa- tion or within the first four years of employment. Research critical for wastewater solutions coming out of our R&D work is an energy-positive waste- water treatment solution that we've called Water En- ergy. It's a next generation wastewater treatment design in which wastewater plants actually become power plants and sources of water." The technology produces clean water by removing organic impurities and sus- pended solids – all while consuming 40-70% less energy than other technolo- gies. This patent pending process promises to deliver a minimum of 5-30% energy positive wastewater treat- ment, he says. World Water Works is working on other technolo- gies that provide similar energy positive wastewater treatment solutions tailored for specific types of waste- water and water reclamation facilities. "We are working on a new technology that produc- es a high quality effluent at a fraction of the total energy consumption of conven- tional wastewater treatment plants. The new technology, developed by Aquanos En- ergy, and further enhanced by World Water Works, captures and harnesses the symbiotic relationship be- tween bacteria and algae." "This natural process results in a 90% reduction in plant energy, reduces a wastewater treatment sys- tem's operational costs by 40-60%, and significantly reduces capital expendi- tures. It is far more sustain- able than other biological wastewater treatment sys- tems that use micro-organ- isms to treat wastewater, so it is ideal for use in India and other energy-constrained countries." ● 44 Getting to grips: gearbox design ● 47 Digging deeper: managing shut downs ● 50 Technically speaking: piano-key weirs ● 52 Nuts & Bolts: products, solutions and services Posters must be submit- ted by 5 September 2014 in high resolution pdf for- mat.

Doctoral study funds Cranfield Water Science In- stitute has received Tranche 2 funding of £3.8m for the Cranfield-led Stream pro- gramme, an Industrial Doc- toral Centre for the water sector. The funding will support the training of fi¢y EngD and PhD students and is being matched by invest- ment from the UK water in- dustry. The university has also finalised its list of short courses and events for 2014, which includes the annual Lorch Lecture, this year on the theme of flood resilient cities with Professor David Balmforth of MWH Global. The majority of Cranfield's short courses are accredited by CIWEM and offer Cran- field credits towards taking up a full MSc. Current research at Cran- field for the water industry includes the Gates Foun- dation funded Nano Mem- brane Toilet, an innovative waterless toilet that requires no access to community in- frastructure. The prototype has re- cently been exhibited at the 'Reinvent the Toilet Fair' in India, where it was highly commended as a design. The team hope to contin- ue work on this project and will be appearing at the Uni- versities Week exhibition at the Natural History Museum in July. INNOVATION HUB Water challenges need new ideas Innovative thinking and collaborations are key to meet global water challeng- es, says engineering company Arup's new publication, 'Out of the Blue'. Mark Fletcher, global water leader, Arup, said: "Sustainable solutions that integrate social, economic and environmental perspectives require new collaborations – fusing insights and ideas from engineering, planning, economics, managerial, environmental and social sciences." The book includes case studies from around the world including: long-term wastewater infrastructure planning in New York a er Hurricane Sandy in 2013; water security in South Africa; the Mersey Basin Campaign (a government-backed cross sectoral partnership) and ecosys- tems services in the Humber Estuary. In a section called 'Water and the Future', Anders Berntell, executive director, 2030 Water Resources Group, highlights the urgency of tackling the problems of flooding and droughts worldwide. "Within 17 years, under a business- as-usual scenario, we are on track to require 40% more water than the earth can supply," said Berntell. "It is the com- bination of widespread practical action and far-sighted processes, approaches and partnerships that will take water out of the top five global risks register and prevent us from requiring more water than the earth can supply." 65% say public's views on infrastructure in uK should be heard even if it delays the project 28th The uK's world ranking for infrastructure quality 27% of Britons are not satisfied with state of national infrastructure 50% of Britons think uK infrastructure is adequate STATS 64% of people trust technical experts over politicians to make national infrastructure decisions
