Abstract
An apparatus for cleaning of wastewater comprising a submerged membrane biological reactor system (MBR) and a submerged membrane module (MBD) wherein the MBR is in fluid communication with the MBD for feeding excess sludge from the MBR to the MBD and wherein the MBR comprises an outlet which releases permeate passed through the membrane of the MBR and the MBD is in fluid communication with the MBR for feeding permeate passed throug the membrane of the MBD back into the MBR and comprises an outlet for releasing gas.
Claims11
An apparatus for cleaning of wastewater comprising:
- a submerged membrane biological reactor system (MBR);
- and
- a submerged membrane module (MBD);
- wherein
- said MBR is in fluid communication with said MBD for feeding excess sludge from said MBR to said MBD, and wherein said MBR comprises an outlet which releases permeate passed through the membrane of said MBR;
- and
- said MBD is in fluid communication with said MBR for feeding permeate passed through the membrane of said MBD back into said MBR and comprises an outlet for releasing gas.
A process for cleaning wastewater using an apparatus according to any of the preceding claims, wherein said process comprises:
- feeding wastewater to be treated into a submerged membrane biological reactor system (MBR);
- feeding excess sludge from said MBR into a submerged membrane module (MBD);
- dispersing said excess sludge in said MBD;
- feeding permeate passed through the membrane of said MBD back into said MBR;
- releasing permeate passed through the membrane of said MBR;
- and
- releasing CO2 produced in said MBD.
