Abstract
Apparatus is disclosed for treating textile desizing effluent so as to provide effective pollution abatement, and to render feasible the recovery of sizing material from the effluent for reuse as well as the conditioning of the effluent so that it may be recycled for desizing purposes.
Claims6
Apparatus for treating textile desizing effluent comprising means for maintaining said effluent at a substantially level size content, means at which said effluent is received as a feed for concentrating and separating a predominant portion of the effluent size content in an effluent concentrate portion, and means for recycling a remaining effluent permeate portion for textile desizing use, said concentrating and separating means being formed by a hyperfiltration system including at least four serially arranged stages yielding permeate in parallel and operating serially to increase the size content in and concentrate while passing degraded size with said permeate, the effluent feed to said serially arranged stages being initially and solely pressurized ahead of the first stage to control system pressure, and the size concentrate discharged at the last stage being controlled by valve means regulating said concentrate discharge suitably for reuse as textile sizing.
