摘要： A round meander septic tank includes an elongate baffle that divides the interior space of the tank into two semicircular chambers. Untreated wastewater is introduced to the first chamber through an inlet located near the first end of the baffle. The wastewater flows through the first chamber to a portal at the second end of the baffle and passes through the portal into the second chamber. A wastewater outlet from the tank is located in the second chamber near the first end of the baffle. Wastewater passing through the portal flows through the second chamber to the outlet and out of the tank. The baffle and the shape of the septic tank increase the distance that the wastewater must flow from the inlet to the outlet as compared to a rectangular meander tank with a single baffle.

摘要： A method and associated system for processing waste gases, liquids and solids, produced by human activity, to separate (i) liquids suitable for processing to produce potable water, (ii) solids and liquids suitable for construction of walls suitable for enclosing a habitat volume and for radiation shielding, and (iii) other fluids and solids that are not suitable for processing. A forward osmosis process and a reverse osmosis process are sequentially combined to reduce fouling and to permit accumulation of different processable substances. The invention may be used for long term life support of human activity.

摘要： The invention relates to a system and a method for treating waste water using a passive phosphorus-capture filter lined with wood activated by the impregnation of a metal in the form of hydroxide, more specifically aluminum hydroxide or iron hydroxide. This system demonstrates phosphorus removal performances which are very closely linked to the release of iron and which support the observation that iron releases follow a cyclical trend. The method according to the invention also clearly demonstrates the cyclical nature of the reduction of phosphorus, directly linked to the same cycle of iron release at the outlet. When the medium is aerobic, it can precipitate the released iron in the form of hydroxide and thereby limit the release of iron into the outflow water and consequently its residual phosphorus. This model thus allows the service life of the system to be extended, while simultaneously taking advantage of the precipitation/solubilization cycle of the iron observed in the medium under reducing conditions.

摘要： A wastewater treatment system for communities not connected to sewer infrastructure. The wastewater treatment system comprises a control unit electrically coupled to an ecologic cleaning system (i.e. phytoremediation), activated sludges and disinfection process (i.e. ultra violet light) in a re-circulation and continuous flow arrangement.
