PATENTSCOPE
It is a reactor for the treatment of water or other liquids based on an Advanced Oxidation process, with different working capacities depending on the volume requirements and characteristics of the fluid to be treated. It is a multifunctional water treatment system, which simultaneously removes ammonium, nitrite and dissolved organic matter, in addition to disinfecting the water continuously and stably. This reactor is called a "Photofilter".
Uses
The technology can be used in aquaculture for water treatment in recirculating culture systems; in the agricultural industry for the treatment of liquid waste from slaughterhouses or slaughtering plants and seafood processing plants; in the forest industry for the treatment of cellulose residues; in mining for the treatment of arsenic; in the treatment of percolated liquids from landfill sites.
Benefits
Multifunctional product: with a single device, functions that must be fulfilled together by the biofilter, the UV filter, the ozone filter, the foam fractionator, and the carbon filter are satisfied.
No pre-conditioning is required to start water treatment.
It can operate in a wide range of water temperatures.
Technological Offer
Technology is available for licensing.
Development status
TRL 4, since it has a functional prototype at a laboratory scale, developed and successfully tested for water recirculation systems in culture (closed systems), in the removal of ammonium, nitrite, nitrate, COD, BOD5, water colour and taste; disinfection of bacteria associated with BKD and SRS, or related to IPN and ISA virus.
