cases where soluble oxides of nitrogen are present and are reduced by the biomass to elemental nitrogen. In accordance with one described embodiment the excess nitrogen is removed by degassing of the mixed liquor in the effluent pit of the system by deepening and widening the usual pit in such manner that the rate of descent of mixed liquor therein to a discharge outlet is less than 0.4 feet per second and the depth is greater than 4 feet, thus permitting the gascontaining macrobubbles to rise to the surface of the pit where these are degassed. The mixed liquor thus freed of macrobubbles is then passed through a hydraulic pressure zone enroute to the clarifier in which pressure zone the nuclei microbubbles are caused to dissolve.

by weight based on solids in a sludge to be treated and an inorganic coagulant or polymeric coagulant are added to the sludge to coagulate the sludge, and water is removed from the coagulated sludge to obtain a filter cake having a low water content.

4558173 HAZARDOUS LOCATION EXPANSION FITTING Padej Gajajiva, Eigil Wium assigned to General Signal Corporation A fitting which couples two conduit members in a manner to permit relative longitudinal motion therebetween and which prevents the gases within the fitting from escaping at a temperature which might ignite an external ambient atmosphere. One form of the fitting includes a bushing affixed to an end of one of the conduit members and positioned and configured to mate with the interior of a body member affixed to an end of the other conduit member to permit sliding motion therebetween. The bushing has sufficient surface area in close proximity to the interior surface of the body member as to cause any gases passed between the bushing and body member to approach a temperature equilibrium with the body member.
