Process to abstract potable water from effluent water by sedimentation, fluidised bed reactor, microfiltration and ultraviolet light disinfection |
摘要 |
<p>In a process to extract potable water from water effluent, the water effluent is subject to preliminary sedimentation, and then treated in an intermediate biological process, followed by filtration. The intermediate biological process takes place in a fluidised bed reactor. The filtration stage is a micro-sieve, followed by immediate disinfection. The first-stage treatment consists of one or more flocculation followed by a lamella screen separator and surrender to the fluidised bed reactor. The fluidised bed reactor has plastic grains with a specific surface area of 800 and 1200 m(2/m(3. The micro-sieve is a steel gauze with a 20-40 m mesh drum. The disinfection process is by ultraviolet radiation.</p> |
