ABSTRACT:
A waste water system adapted to receive liquid waste from a septic tank or the like and purify the same.
There is a primary processing section comprising a first processing tank to receive the waste water. This primary section has air operated valve means to cause the operating steps, namely the opening and closing of the inlet and outlets of the tank, aeration of the liquid in the tank, supplying a dose of a treatment liquid into the liquid of the tank, and also causing recirculation of some of the biomass in the tank back to the septic tank. The liquid from the first processing section is transmitted to a second processing section where the liquid is circulated through filters, and also through an ultra-violet heater to cause final purification of the liquid. There is a control system which is responsive to liquid level in the two tanks, and also responsive to air pressure in a compressed air manifold that supplies pressurized air to various valves to control the operation of the system.
