Abstract: Systems for venting odors from a toilet bowl include a toilet having a bowl defining a headspace and having a plumbing connection to a vent stack, a plurality of micro-vacuum pumps in fluid communication with the headspace of the bowl of the toilet and in fluid communication with the vent stack. The fluid communication with the vent stack can include a saddle configured to mount to the vent stack. The saddle has an elongate seat that includes a plurality of tubular taps extending therethrough at an orientation transverse to a longitudinal axis of the saddle, and a means for attaching the elongate seat to the vent stack. When the saddle is mounted to the vent stack, each of the tubular taps creates fluid communication between the interior of the vent stack and one each of the plurality of micro-vacuum pumps.

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.
