METHOD AND DEVICE FOR TREATING AQUEOUS FLOWS IN A BIOREACTOR, AN ULTRAFILTRATION UNIT AND A MEMBRANE FILTRATION UNIT |
摘要 |
<p>A novel method for purifying, by means of an essentially closed circuit water purification system, an aqueous flow from a processing unit includes the steps of: (a) supplying to a bioreactor, and combining therein, the aqueous flow, as well as a discharge flow from a membrane filtration unit; (b) allowing microbiological conversion of biodegradable constituents to take place therein, thereby, generating an effluent flow; (c) supplying the bioreactor effluent flow to an ultrafiltration unit, thereby, separating the effluent flow into permeate and concentrate flows; (d) supplying at least some of the permeate flow to a membrane filtration unit, thereby, generating a product flow and the discharge flow; and (e) supplying the discharge flow to the bioreactor, as noted in step (a), and supplying at least a portion of the product flow to the processing unit. Apparatus related thereto are also disclosed.</p> |
