<p>A system for treating sanitary wastewater using membrane filtration is disclosed. Designed principally for complete on-site sewage treatment and disposal, the system separates wastewater into permeate (22) and concentrate (23) components by membrane separation subsystem (32); then dries, disinfects, and deodorizes the concentrate (23) component by a variety of methods to render it reusable or more easily stored and disposed. The permeate (22) component is discharged or reused as is, or is further treated to render it disposable or reusable for particular applications. Alternatives for treating the concentrate (23) component include mixing with alkaline admixtures and composting with other cellulose-based wastes. Alternatives for treating the permeate (22) component include deodorization and biological stabilization by ultraviolet radiation and ozonation. The apparatus includes membrane separation subsystem (32), a liquid treatment subsystem (34), and a solids treatment subsystem (36).</p> |
