GE Power & Water has a new membrane, the AG LF series, that purifies tough-to-treat water such as industrial wastewater. The low-fouling reverse osmosis (RO) membrane resists degradation from bacteria, colloids and other fouling materials. It has less frequent cleaning cycles leading to extended life, lower operating pressure and high efficiency.

Lystek’s biosolids management system involves a combination of heat, alkali and high shear mixing to breakdown biological material from wastewater treatment plants. The resultant liquefied biosolid material provides fertilizer for farm lands, while recycling processed biosolids to anaerobic digesters enhances biogas/methane production by 25%. Lystek, based in the Waterloo, Ontario region, won an award for its innovations at the 42nd Annual Water Environment Association of Ontario Conference in Toronto in April.

Power-Pipe Drain Water Heat Recovery Systems from RenewAbility Energy of Kitchener, Ontario are all-copper, double walled heat exchangers. They recover heat energy from wastewater and use it to warm incoming cold water, based on a “falling film” effect. The systems are UL-listed for potable water and scalable for large and low flow applications. Ontario is the first jurisdiction to provide direct energy credits for DWHR technology within its building


A new generation of “off-the-shelf” Movitec vertical multi-stage pumps from KSB Canada are efficient high-pressure in-line pumps with seal variants rated from -30 C to + 140 C. The centrifugal pumps handle a variety of media and applications ranging from fluid transfer to instant pressure boosts. They handle volumes up to 113 m3/h and discharge up to 2,496 kPA.
