New Technology of American Entrepreneurs Will Help to Reduce Phosphorus and Nitrogen Pollution

Aug 21st, 2017

Clearas Water Recovery, the company from the city of Missoula, Montana, has patented the technology of cleaning water from phosphorus and nitrogen in water-treatment stations.

The aim of the chemical engineers was to prevent the poisoning of local waterways with the chemicals, which cause fatal harm to aquatic flora and fish. The technology involves the use of algae for water purification and algae as biofuel and fertilizers. The problem of water pollution with phosphorus and nitrogen waste is becoming strongly relevant to the world. If these two substances get into the water, so-called “dead zones” appear where algae intensively bloom. It causes oxygen starvation of other plants and living inhabitants of water bodies and finally kills them.

Clearas Water Recovery offers to get rid of this environmental nightmare plus earn money from this. Wastewater containing high concentrations of phosphorus and nitrogen is a favourable environment for the active growth of algae. The idea of American businessmen is that they remove harmful substances from wastewater before they get into streams, rivers and lakes. The advantage of this method is biological safety while other existing cleaning technologies involve the use of chemicals.

The company was created after Bitterroot Valley farmers began to use nitrogen and phosphorous from wastewater of local cleaning stations as biofuel. In addition, the administration of the treatment facilities had to think about the idea to create a technology for cleaning wastewater from hazardous elements. They constructed a test installation of a new technology that was able to clean up to 15 thousand gallons of sewage per day. As a result, water, which has become much cleaner, can be safely discharged into the water body.

A new sewage treatment technology allows receiving of many byproducts that can be used with advantage. New technology recovers nutrients in the water, and also uses centrifuges, which turn algae into any form acceptable to the customer. For example, algae can be turned into aqueous sludge to use it as a fertilizer, or be processed in the dry semifinished product for the production of fuel or plastics.

The representatives of Clearas Water Recovery say that their technologies have already attracted many of the national farmers as well as companies from Europe and Asia. New technological solutions of wastewater treatment can solve many environmental, political, and economic problems.
