Abstract
420,720. Treating sewage. PORTEOUS, W. K., 6, Netherton Road, St. Margaret's, Twickenham, Middlesex. Nov. 18, 1933, No. 32219. [Class 111] Plant for treating sewage sludge by the wet-carbonization process comprises a recuperator through the heating portion d of which sludge is passed from a receptacle a by a pump b for delivery through a multi-way valve e to one of a series of receptacles f<1>, f<2>, f<3> while sludge is drawn from another of the receptacles through the valve e by a pump h and passed through the cooling portion j of the recuperator to a filter-press k, or other device for separating solid from liquid. Sludge held in the third receptacle is heated therein by steam coils or a steam jet or jacket. The valve e is of the rotary plug type which allows of one receptacle being connected to the pipe d while another is connected to the pump h. It is stated that the sludge may be transferred from the receptacles f<1>, , f<2>, f<3> to the filter-press by steam pressure. The recuperator may be arranged in a heated chamber.
