Abstract: A method for wastewater treatment which comprises (a) separating and/or collecting urine from the wastewater for pretreatment, (b) removing phosphorus from urine using seawater, (c) optionally oxidizing nitrogen from urine, and (d) discharging the phosphorus-removed and/or nitrogen-oxidized urine to a sewer.

Abstract: Biological wastewater treatment of wastewater is performed by oxidizing organic carbon with sulfur or a sulfur compound as an electron carrier, and reducing the sulfur or sulfur compound to sulfide. The sulfide is oxidized with nitrate or oxygen. If necessary, ammonia is oxidized to nitrate and then reduced to nitrogen gas. The process is effective for saline waste water facilities, as well as non-saline waste water facilities.

Abstract: Wastewater influent is supplied to an aeration zone having a membrane module. Activated sludge is established in the aeration zone and an oxygen surplus is maintained by controlling a rate of oxygen supplied to the aeration zone. Wastewater influent is mixed with the activated sludge to form a first mixed liquid. A portion of the first mixed liquid is filtered to form a filtrate and unfiltered activated sludge. The unfiltered activated sludge is mixed with the activated sludge in the aeration zone to form the first mixed liquid. A portion of the first mixed liquid is transferred from the aeration zone to an anaerobic zone, and a second portion of first mixed liquid is mixed with activated sludge in the anaerobic zone to form a second mixed liquid. The second mixed liquid is recycled to the aerobic zone.
