Founder

Jerry Hanna

Founder, President & CEO

Jerry Hanna founded Clearflow in 2005 after four decades in water and wastewater treatment, with a focus on environmentally safe chemistry, sediment and erosion control, and meeting regulatory standards without building complex plants.

As inventor and patent holder of Clearflow’s Gel Flocculant line, Lynx solids-management products, GFR treatment systems, and Accelerated Solids Removal Technology (ASRT), Jerry has driven collaborative research with the University of Alberta and grown a distribution network spanning multiple countries.

His founder story continues to guide Clearflow’s mission: practical, passive treatment that restores healthy watersheds for mining, construction, municipal, and industrial clients worldwide.

    Dr. Edyta Jasinska

    Aquatic Biologist & Limnologist

    Dr. Edyta Jasinska is an aquatic biologist and limnologist with over 25 years of experience in the field. She has a Ph.D. from the University of Western Australia and has completed three postdoctoral fellowships in Alberta. Her work in Australia and Canada dealt with the sensitivity to anthropogenic impacts of aquatic ecosystems including ponds and wetlands, lakes, springs, streams, and cave waters. Since 2015, Dr. Jasinska conducted research with Dr. Greg Goss on the effects of polymer flocculants on fish gills, physiology and effects on aquatic invertebrate communities. Edyta worked directly for Clearflow Group in collaboration with other U of A scientists on a research and development project to develop techniques for low level detection and measurement of polymers/flocculants in water and to define best conditions for amelioration of cationic polymer toxicity to fish. The development of a method for measurement of cationic polymers in fresh water has been very successful and presently, Edyta is continuing to work on the collaborative project between Clearflow and U of A to help with developing a similar method for measuring anionic polymers in fresh waters.
