Latest Patents

One of Rath's latest patents is a biological wastewater treatment system containing a salt-rejecting membrane filter and recycle conduit. This system includes a biological reactor with anaerobic, anoxic, and aerobic chambers. A lift station, equipped with a pump, is connected to a tertiary filter downstream of the biological reactor. The lift station receives biologically treated liquid from the tertiary filter and pumps it for further processing. The filtration subsystem, which is connected to the lift station, filters the liquid and includes a preliminary filter and a salt-rejecting membrane filter. This filter has a recycle conduit that recirculates the salt-rejecting membrane filter, creating a salt concentration loop between the biological reactor and the filter. Additionally, a post-filtration subsystem is designed to receive permeate from the salt-rejecting membrane filter, incorporating an adsorbent and oxidation system.

Another significant patent by Rath is a method and apparatus for residential water recycling. This system also features a biological reactor with anaerobic, anoxic, and aerobic chambers. The lift station in this system is connected to the biological reactor and pumps biologically treated liquid. The filtration subsystem filters the liquid and includes a salt-rejecting membrane filter with a concentrate recirculation conduit. This conduit recirculates the concentrate to a point upstream of the filter, forming a salt concentration loop. The post-filtration subsystem receives permeate from the salt-rejecting membrane filter and includes a water disinfection system that generates potable water.
