Abstract
A process for treatment of biological waste includes passing biological waste liquid downwardly through at least one substantially vertically oriented curtain having a reinforcing layer of support material. Attached thereto is at least one layer of flexible reticulated open cellular material having a plurality of communicating cells which form a support for filamentous micro-organisms and/or symbionts included in the filamentous micro-organisms. The filamentous micro-organisms and/or symbionts form a dense mat of cellular material adhering to the support. The biological waste is collected after passage through the curtain for ultimate disposal.
Claims25
A process for treatment of biological waste including the steps of:
- (i) passing biological waste liquid downwardly through at least one substantially vertically orientated curtain having a reinforcing layer of support material and attached thereto at least one layer of flexible reticulated open cellular material having a plurality of communicating cells which form a support for filamentous micro-organisms and/or symbionts included in said filamentous micro-organisms and wherein said filamentous micro-organisms and/or symbionts form a dense mat of cellular material adhering to said support;
- and
- (ii) collecting said biological waste after passage through the curtain for ultimate disposal.
A waste treatment plant for treatment of biological waste including:
- (i) at least one hanging curtain having a reinforcing layer of support material and attached thereto at least one layer of flexible reticulated open cellular sheet material having at least one broad surface for supporting growth of adherent filamentous micro-organisms;
- (ii) means for applying biological waste in liquid form to the broad surface of the hanging curtain;
- (iii) means for passing pressurised air over the broad surface of the hanging curtain;
- and
- (iv) collection means for collecting processed waste effluent after passage through the curtain.
