Rekon Ion Exchange

Industrial Wastewater Recycling and Heavy Metals Recovery

Kontek has been a leading manufacturer and pioneer of fully automated self- regenerating ion exchange industrial wastewater recovery systems for over 35 years. ReKon Ion Exchange Systems have proven to be a reliable and cost-effective method of removing dissolved heavy metals and salts from wastewater and producing high quality de-ionized water for recycling.

Kontek’s customers use ReKon technology for a wide variety of applications, including: raw water purification, softening and deionization; wastewater treatment, wastewater recovery and recycling; polishing and targeted ion recovery.

Carousel and CIX Systemhttp://kontekecology.com/wp-content/uploads/2013/09/Rekon-and-Pilot-300-by-1421.png

Efficiency Configurations:

Carousel Design: Consistently rotate three columns sequentially through the lead/lag/standby positions to optimize  24/7 system productivity.
Cyclic Ion Exchange (CIX): Reduce costs for brine by reusing RoKon RO reject for regenerating resin beads in precursor water softeners.




Orbite Resin System Overview

RoKon Reverse Osmosis Purification

Reverse Osmosis


Reverse Osmosis Purification removes 99% of contaminants. Designed for efficiency, Kontek’s Reverse Osmosis systems recover up to 85% of the raw city or recovered process feed water by re-circulating the reject water portion back a second pass for retreatment.

Self-regenerating resin systems


Lead and standby modes enable complete resin regeneration, reducing system downtime and cutting costs. Protect your resin by automatically pre-treating wastewater with chemical precipitation and carbon filters.



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.
