摘要： A wastewater recycling system includes a biological reactor having anaerobic, anoxic, and aerobic chambers. A lift station including a pump is operatively connected to the biological reactor. The lift station receives biologically treated liquid from the biological reactor and pumps the liquid from the lift station. A filtration subsystem is operatively connected to the lift station. The filtration subsystem receives and filters the liquid pumped by the lift station. The filtration subsystem includes a salt-rejecting membrane filter comprising a concentrate recirculation conduit operatively connected to recirculate salt-rejecting membrane filter concentrate to a point along the wastewater recycling system upstream of the salt-rejecting membrane filter, thereby forming a salt concentration loop between said point along the wastewater recycling system and the salt-rejecting membrane filter. A post-filtration subsystem is operatively connected to receive salt-rejecting membrane filter permeate, and comprises a water disinfection system that disinfects the permeate thereby generating potable water.

摘要： Inside structure to insert into a tank in order to form a reactor for waste water treatment. The structure is obtained by assembling two matching modular elements or "walls". Each element comprises planar portions which are brought into abutment with each other. Each element comprises the shell of a half inverted cone, the two shells of the two elements matching so that a separation chamber in the form of an inverted truncated cone is formed when the two elements are assembled. The two elements can form other chambers or pipes when they are assembled, such as an inlet chamber into which a strainer basket can be inserted, or an air-lift recirculation pipe for instance. Together the two elements provide the functional components essential to the functioning of a reactor in a compact volume, and they can be inserted in a tank in order to construct a reactor. The reactor can be used to treat water by nitrification and denitrification. In an alternate embodiment, the two elements comprise a quarter cone each, instead of a half cone. When they are assembled, they form a half cone, which is fixed to a surface of the tank in which it is inserted. In the last embodiment, there is only a single modular element, which is a quarter cone, and can be inserted in the corner of a rectangular tank in order to form an inside structure.

摘要： Biological reactor for wastewater treatment from minor sources of pollution using activation process with activated sludge in upflow and/or with growth culture, where all processes of biological treatment with activation process take place in a single-tank biological reactor, where functional areas of mechanical pre-treatment, aeration and activated sludge separation are spatially separated. The biological reactor contains a tank (1), in which a separation chamber (4) is centrally situated, an area between a casing (5) of the separation chamber (4) and a casing (2) of the tank (1) is divided into two parts by two vertical partition walls A (7) and B (8) spanning from a tank bottom (3) to a bottom of a discharge piping (29), namely into a mechanical pre-treatment chamber (11) and an aerated chamber (12). Recirculation of activated mixture from the oxic aerated chamber (12) into the mechanical pre-treatment chamber (11) is provided in such manner that pre-treatment chamber (11) and the aerated chamber (12) are connected by an opening (19, 22) in the upper parts of both vertical partition walls A (7) and B (8), wherein aeration elements A (36) and B (37) located near the bottom of the aerated chamber (12) in front of partition walls A (7) and B (8) are situated so that a height of the water column over the aeration element A (36) is lower than a height of the water column over the aeration element B (37) and/or an air flow regulator (42, 43) for the aeration elements A (36) and B (37) provides air flow regulation in such manner that the amount of the air conveyed into the aeration element A (36) is higher than the amount of the air conveyed into the aeration element B (37), which allows to create horizontal circulation of water surface layer of activated mixture around the upper part of the casing (5) of the separation chamber (4), namely from the opening (19) in the partition wall (7) through the mechanical pre-treatment chamber (11) of to the opening (22) in the partition wall B (8) and through the opening (22) in the partition wall B (8) to the aerated chamber (22) and further to the opening (19) in the partition wall A (7).
