Kemco Systems, a long-time innovator of water and wastewater treatment within the laundry industry, recently announced the award of patent for its KLEENWATER system. The patented process employs the combination of Kemco’s ceramic membrane filtration system and specialized reverse osmosis technology which conserves water and thermal energy. Kemco says it is the only company in the industry with the ability to combine these treatment systems while maintaining thermal energy.
The system presents a cost-effective means of combating rising water, sewer and energy costs by removing emulsified, suspended and dissolved contaminants including PFAS and microplastics from wastewater without utilizing high volumes of chemicals. The well-established process has demonstrated consistent reuse of 75% to 85% of a plant’s water and thermal energy in the same process, all while reducing consumption of wash aisle chemistry.
“This patent is recognition of Kemco’s pioneering approach to recycling wastewater and recovering thermal energy within the laundry market," said Tom Vanden Heuvel, Kemco CEO.
This patented approach not only delivers solid returns, but also enables plant operators to demonstrate a commitment to environmental stewardship. The process reuses water and reduces greenhouse gas emissions by lowering the plant’s heating load.
The core of the system is the combination of the company's ceramic membrane filtration and reverse osmosis technology. This ceramic membrane process is based on high-velocity crossflow filtration with wastewater being filtered through ceramic ultrafiltration elements. The result is a filtrate free of oils, greases, suspended solids, viruses, bacteria and microplastics.
The high-temperature reverse osmosis process uses specially designed and purpose-built membranes to remove remaining dissolved constituents, color and PFAS from the filtrate. The approach allows laundry facilities to return the highest quality water to their wash aisle, reducing chemical usage and ultimately delivering softer goods and whiter whites.
Kemco has built its business on helping clients reduce operating costs while improving their environmental footprint. The award of this water recycling process patent is validation of the company's commitment to transforming how the industry protects vital water resources while achieving system ROI and sustainability goals.
