Case Studies


Aerospace manufacturers achieve 100% membrane regeneration after four years with SmartLogic

Learn more about how this facility reduced operating costs by 40% and recovered 85% of its wastewater — all while using the original membranes.  The client has benefited from exceedingly high recovery rates and ongoing low operating, repair and maintenance costs. After four years of continuous use, their system’s membranes still appear untouched and consistently regenerate to 100% performance. This benefit alone has saved the customer thousands of dollars in membrane replacement and installation.


Semiconductor creators reduce operating costs and extend system lifespan

Learn more about how this facility’s Kontek system has remained completely intact over the past eight years — despite being exposed to extremely corrosive wastewater conditions. Based on Kontek’s ability to treat and recover complicated multi-acid wastewater, Kontek is renowned by many microchip, photovoltaic, semiconductor and silicon wafer manufacturers across the world. 

Heavy Metal Removal Technologies

Conventional Treatment


Our conventional wastewater treatment systems use chemical precipitation to consistently remove contaminants. Efficiently treat your wastewater prior to re-use or safe environmental discharge with durable and long-lasting automated systems.


Filter Press

dual filter press


Quickly transform your liquid discharge into a solid form that passes the slump test. Presses consistently transform aqueous solution containing 2 to 5% total suspended solids  (TSS) to solid sludge cakes containing less than 65% moisture for easy disposal. Paired with a sludge dryer, your filter press is an important step in achieving Zero Liquid Discharge (ZLD).

Sludge Dryer

sludge1Sludge dryers are designed to match your filter press capacity, giving you an efficient semi-continuous  batch process. Its compact and customized build minimizes both floor  space requirement and operator interference. Sludge falls directly from the filter press into your dryer, minimizing handling and exposure to hazardous waste.

Liquid Crystallizer

Slurry + Catwalk

Perfect for low-volume, corrosive liquid solutions, ConRec Liquid Crystallizers quickly remove moisture content, leaving behind crystallized salts for disposal. With a trustworthy design used in the industry for over 25 years, the liquid crystallizer eliminates contaminated haulage and disposal costs.




ReKon Ion Exchange is a reliable and cost-effective method of removing dissolved heavy metals and salts from wastewater and producing high quality deionized water for recycling. Some of the applications: raw water purification, softening and deionization; wastewater treatment, wastewater recovery and recycling; polishing and targeted ion recovery.




SmartLogic’s intuitive design protects your water quality, safeguards your parts and conserves chemicals – all while minimizing labour requirements. Sophisticated, yet user friendly HMIs enable you to quickly fine-tune parameters  with precision, view analytics and respond to alarms.
