New Logic Research's VSEP helps turn cow manure into clean water
MARKET PROSPECTS 3D design allows the biofilm to grow in a controlled and protected way until reaching a predetermined thickness. The use of these supports will eliminate the biodegradable filtered COD from the water and avoid the possible formation of calcium precipitates.

Evoqua to upgrade clarifiers at Dayton water reclamation facility
E
voqua Water Technologies is to provide clarifier upgrades for the Dayton Water Reclamation Facility in Dayton, Ohio, USA. The Evoqua Municipal Division will replace eight 160-ft clarifier tanks with stainless steel secondary clarifiers featuring the Tow-Bro Hydraulic Sludge Removal System and FEDWA Energy Dissipating Inlet (EDI), both part of the Envirex product family. The FEDWA EDI reduces flow velocities and improves flocculation for more efficient solids settling and increased treatment capacity. The Tow-Bro System removes settled solids with a hydraulic unitube header. Evoqua worked closely with its sales representative Henry P Thompson Company, on the upgrade project.
New Logic Research’s VSEP helps turn cow manure into clean water

ew Logic Research has announced the successful commissioning of a VSEP vibrating membrane system in the Italian Alps region of Wipptal to make clean water from digested cow manure. The VSEP system takes the effluent from an anaerobic digester and transforms it into clean water which can either be reused or safely discharged to the environment. The project was implemented with the assistance 4
Pump Industry Analyst
of OB Impianti, New Logic’s distribution partner in Northern Italy. VSEP’s patented vibratory shear mechanism coupled with an innovative filter pack design means it can create clear permeate from water heavily laden with biological material like cow manure. The Wipptal project takes cow manure from more than three dozen local farmers. The liquid manure is transported to the treatment facility where more than 60% of it is transformed into clean water, while the remainder is turned into concentrated organic fertilizer. The only pretreatment between the digester and the VSEP is a 100 micron screening device to remove large particles from the feed material. OB Impianti and New Logic are currently working on two additional installations in Europe.
Proposal to refreeze Arctic ice calls for 10mn wind-powered pumps
A
proposal to tackle global warming by thickening Arctic ice using millions of wind-powered pumps to move seawater on to the surface of the ice has been outlined by scientists at Arizona State University (ASU). The cost to deploy the devices over 10% of the Arctic would be about US$500 billion but current trends of ice loss caused by climate change could be reversed. In the article Arctic Ice Management published in the journal Earth’s Future, the ASU scientists outline a geoengineering proposal to create more ice during the Arctic winter by pumping water directly to the surface where it can freeze more rapidly, thickening the ice. This idea is not new but the implied scale of the technique (which involves the production of ice over millions of square kilometres) may have discouraged further investigation. The proposal states that a wind-powered pump mounted on a large buoy could perform the function of capturing wind energy to pump seawater to the surface. There is enough wind power in the Arctic for a single wind turbine with 6 m diameter blades to pump 1.3 m of water over about 0.1
km2 over the Arctic winter. About 10 million wind-powered pumps would therefore be required to cover 10% of the Arctic Ocean, or 1 million devices per year assuming an implementation period of 10 years. These devices would have to be manufactured and delivered to the Arctic Ocean and maintained in the harsh Arctic environment. The engineering challenges of this task are evident but an equally important question concerns its financial feasibility. In the ASU scientists’ estimates, the cost to manufacture and deploy each pumping device is around US$50 000. To deploy the devices over 10% of the Arctic over 10 years would therefore cost about US$50 billion/ year. To deploy such devices over the entire Arctic would require about US$5 trillion over 10 years, or about US$500 billion/year. The scientists conclude that winter ice thickening by wind-powered pumps should be considered and assessed as part of a multi-pronged strategy for restoring sea ice and arresting the strongest feedbacks in the climate system. Questions about the feasibility of the device and its local effects would probably be best solved by building a prototype for experimentation in the field.

Emefcy and RWL Water partner to target Chinese market
A
ustralia’s Emefcy Group Ltd and RWL Water have formed a strategic alliance to accelerate both companies’ penetration of the water treatment market in China. Emefcy will enlist RWL Water’s engineering expertise in designing and producing a range of packaged plant solutions for the China market. Under the terms of the agreement, Emefcy will pay RWL Water for engineering services in expediting the design of the spectrum of packaged plant solutions for China, as well as engineering and production services to complement Emefcy’s MABR technology. Each company will also receive commissions on the sale of the other company’s products.
