Abstract
Methods and systems for treating waste water in residential, industrial and agricultural environments are disclosed. The methods and systems for treating waste water can be localized and self-contained with no need to channel sewage to a remote location. The waste water treatment methods and systems result in recycled clean water, concentrated effluent, and disposable solids. The recycled water can be used for landscaping and domestic use. The concentrated effluent can be channeled to an anaerobic digester to generate biogas, such as hydrogen, methane, and/or carbon dioxide, which can be used to generate power or as fuel for heating and/or cooking. The disposable solids may be used as fertilizer for farming or gardening.
Claims21
An apparatus, comprising:
- a) a first chamber for receiving waste water;
- b) a plurality of filters, arranged radially around a central axis, configured to receive the waste water from the first chamber and, upon being rotated around the central axis, retain elements of the waste water having at least a first minimum size and to allow a filtered mixture to pass through, the filtered mixture having particles therein with a size less than the first minimum size;
- c) a second chamber configured to collect the filtered mixture;
- d) a connector path configured to carry the filtered mixture from the second chamber;
- and
- e) a plurality of filtration modules, arranged radially around the central axis, configured to receive the filtered mixture at a near end of each filtration module to the central axis and, upon being rotated around the central axis, separate a concentrate from the filtered mixture and produce substantially clean water from the filtered mixture, the concentrate having particles therein with a size greater than a second minimum size, the second minimum size being significantly smaller than the first minimum size, and each filtration module having:
- i) at least one porous filter separating an inner chamber of the filtration module from an outer chamber of the filtration module and allowing a permeate to pass from the inner chamber into the outer chamber,
- ii) a permeate outlet connected to the outer chamber that transports the permeate away from the outer chamber, and
- iii) a concentrate outlet at a distal end of the inner chamber and/or the porous filter.
