Patent number: 11339068Abstract: A process for treating domestic wastewater may include directing wastewater into a tank containing a membrane filter and mixed liquor. The process may include recirculating wastewater and mixed liquor from a top end of the tank into a bottom end of the tank via a recirculation conduit. The process may include introducing a flow of wastewater and mixed liquor from the recirculation conduit into an aeration device and drawing ambient air into the aeration device using the flow of wastewater and mixed liquor from the recirculation conduit. The process may also include drawing wastewater and mixed liquor proximately surrounding the aeration device into the aeration device using the flow of wastewater and mixed liquor from the recirculation conduit.

Patent number: 9993742Abstract: A process for production of minerals using an evaporation unit comprising an evaporation element for exposing thereof to the atmosphere for evaporation of a liquid solution therefrom. The evaporation element comprises an evaporation surface and a texture for deflecting the solution during movement along the surface, leaving minerals on the surface as a result of evaporation of the solution. The texture allows the minerals to detach from the element under the sole influence of normal forces of nature before the minerals reach a weight capable of damaging the evaporation unit. The process includes wetting the element with the solution, which at least partially evaporates and forms precipitated minerals, at least some of which are left on the surface; and letting the minerals detach from the surface solely under the influence of normal forces of nature before the minerals on the surface reach a weight capable of damaging the unit.Type: GrantFiled: August 25, 2015Date of Patent: June 12, 2018Assignee: LESICO TECHNOLOGIES LTD.Inventors: Efraim Ramon, Jack Gilron
