ABOUT PG CleanWater Solutions
Innovative solutions with solid partners and products
For the last 30 years, in addition to supplying the pulp and paper production industry, the focus has been on addressing environmental challenges and introducing new, efficient technologies for process water treatment and water conservation, as well as the efficient handling of various sludge qualities from effluent treatment plants. In 2017, our company became the European partner of Fournier Industries Inc., Canada, enhancing its focus on solid-liquid separation and dewatering solutions for the biomass/gas, effluent treatment, and aquaculture industries.
From paper to biomass:
![]() Founder & Board member |
PG Clean Water Solutions AS, formerly know Lange Lyche Teknisk AS has its roots dating back to 1973. Founded by Jens Fredrik Lange Lyche, the company had a long history of serving the pulp and paper industry before shifting focus towards air and water purification.
Since 2017, we've partnered with FOURNIER INDUSTRIES Ltd., supplying the innovative FOURNIER ROTARY PRESS™ for solid-liquid separation for the industries of Europe, marking our expansion into new markets.
In 2023, a collaboration with Norwegian pump specialist PG Flow Solutions was established. PG Flow Solutions, a provider of bespoke pumping solutions since 1982, enhances our offerings, especially with their in-house capabilities at PG HQ in Sande, Norway. This partnership grew stronger when PG Flow Solutions invested into LLT, helping solidify our position as a comprehensive system supplier catering to diverse sectors including Aquaculture, Energy, and Wastewater Treatment industries.
In September 2023, Lange Lyche Teknisk secured an exclusive distributor agreement with FOURNIER INDUSTRIES for the FOURNIER ROTARY PRESS™ in Europe (excluding France), reinforcing our market presence.
The year 2024 saw PG Flow Solutions increase their stake further by securing 100% ownership of Lange Lyche Teknisk AS. With an ever-increasing focus towards wastewater and sludge treatment, it was only natural for the company to take on a new profile in line with the rest of the PG Group. Thus a new company name, "PG CleanWater Solutions AS" was launched in March 2025.
Today, PG CleanWater Solutions is a hub of specialized expertise, guiding decision-makers in Aquaculture, Biomass/Biogas, Pulp & Paper, and municipal Wastewater and Sewage treatment towards sustainable, cost-effective solutions.
Our dedicated team of engineers and technicians is committed to helping clients optimize their processes and propel industries forward.
