Abstract
Small-scale waste water treatment plant as described in the parent patent comprises a single vessel in which the water is aerated, flocculated and decanted to produce a purified effluent acceptable for disposal in local drains or rivers. Purified effluent is piped to the vessel's outlet from a collecting channel of large area. The channel is maintained, pref. by float supports, at a level below the surface of the liq. but above the settled sludge. Improvement is that gas under pressure, usually compressed air, can be injected into the pipe between the collecting channel and the vessel outlet in order to eject treated effluent from the outlet. Rapid discharge of treated effluent without pumping or gas pressure within the vessel. These other two methods tend to stir up the settled sludge which is carried out in the treated effluent.
