Biomimetic Solid Separator

Technology Benefits

Low operational energy requirement In-expensive scalable device No clogging due to absence of membrane Capable of treating fragile particles Little or no device cleaning process required Device can either replace the existing filtrating system or can be used as a complementary device to filter fragile particles before or after other particle separation operations

Detailed Technology Description

The efficiency of conventional separation methods such as centrifugation, filtration or sedimentation is generally poor. When the target solids are small, have a density similar to that of the fluid phase and are fragile, the energy consumed during separation is high. There is a need for new technology to address the deficiencies of conventional separation methods. Researchers at the University of California, Davis have invented a new device for separating solids from liquid or air that is based on biomimetic concepts. This new device uses fluid dynamics principles to overcome some of the deficiencies of conventional methods and provides an economical and effective alternative for the separation of difficult to remove particles. Details of the device such as dimensions, shape and structures can be modified to achieve optimum performance with particles of different size and specific gravity. The device can be scaled up or down depending on the amount of fluid to be treated hence can be used in diverse settings.

Title: Photocatalytic reactor and process for treating wastewater
Usefulness: Photocatalytic reactor and process for treating wastewater
Summary: As a photocatalytic reactor useful in treatment of wastewater from a confined aquaculture, by removing ammonium, nitrite and dissolved organic matter from the wastewater, to purify and disinfect the wastewater (claimed) obtained from confined aquaculture such as culture systems for fish, shellfish and crustacean, on their egg-larvae production phase, juvenile-seeds, fattening-growth, antibiotic application and maintenance of reproducers.
Novelty: Photocatalytic reactor for purifying and disinfecting wastewater from a confined aquaculture, comprises UV light sources; and titanium dioxide based catalyst, supported on glass plates that are fixed at a distance from UV light source
