    Abstract: Methods and systems are provided for treating wastewater to simultaneously remove nitrogen, carbon, and phosphorus. The process includes an anoxic tank that receives at least two streams, including plant influent wastewater and return activated sludge. These streams are mixed in the anoxic tank to promote phosphorus release and fermentation of particulate and dissolved organic matter. The mixed liquor is transferred to an aerated tank having low dissolved oxygen concentrations to promote development of phosphorus-release bacteria that is eventually recycled to the anoxic tank by way of the return activated sludge. Simultaneous nitrification, denitrification, and phosphorus release occur in the aerated tank. A membrane tank separates treated effluent from activated sludge in a membrane tank.

    Abstract: Disclosed are apparatus and method for alternative aeration-effluent wastewater treatment using a ceramic membrane, which allows the biological treatment to be performed sufficiently in an intermittent aeration tank by combining an anaerobic tank with a plurality of intermittent aeration tanks and selectively changing an inflow path of influent water according to an operation status of the intermittent aeration tanks. The present disclosure is directed to providing an apparatus and method for alternative aeration-effluent wastewater treatment, which allows the aeration and treated water to continuously discharge through two intermittent aeration tanks by independently forming an air injection line and a treated water discharge line at a ceramic membrane provided in each intermittent aeration tank.

    Abstract: A method for the biological treatment of wastewater containing pollutants, using an aerobic biomass, includes a plurality of successive cycles of a predefined duration in order to achieve pollutants removal efficiency of 90% or higher, each of the cycles including the following steps: introducing a wastewater effluent containing phosphorus and calcium into a reactor containing biomass; applying an aerobic phase by introducing into the reactor a gas flow containing oxygen for a predefined length of time, sufficient to form aerobic biomass granules; decanting the aerobic biomass granules thus formed; and removing at least part of the treated effluent. After each step of introducing effluent into the reactor, the pH in the reactor is maintained at a value above 8 for a length of time at least equal to 10% of the cycle duration.
