    Abstract: A method for cleaning and preventing diffuser membrane fouling of an aeration system can include: transporting a liquid acidic solution into a downcomer pipe or a purge line positioned in a reservoir of an aeration system containing a body of water such that the liquid acidic solution flows into a manifold and air distribution pipes; allowing the liquid acidic solution to vaporize; and blowing the vaporized acidic solution into a plurality of diffusers supported by the air distribution pipes. An aeration system that can implement the method is also included.

    Abstract: A method of processing waste water to produce a filtrate is provided. The method includes the steps of: introducing untreated wastewater to an inlet zone of a bioreactor; introducing a concentrate of treated waste water with at least 10,000 mg/L of total suspended solids into the inlet zone of the bioreactor to form a biological active mixture; aerating the biological active mixture in an aeration zone of the bioreactor to produce treated waste water; filtering the treated waste water to produce a filtrate and the concentrate, wherein the filtrate created by the filtering has total suspended solids of less than 10 mg/L; transferring at least a portion of the concentrate to the inlet zone of the bioreactor; and transferring the filtrate external to the bioreactor as clean water.

    Abstract: A wastewater treatment method provides a bioreactor including: an inlet zone, a filtration zone, and a reaction zone including: a biofilm supporting media including a biofilm of bacteria thereon. The supporting media is sufficient to enable the bacteria thereon to consume contaminants from the wastewater to produce water with a total suspended solids of less than 5 g/L and water including suspended bacteria. Wastewater is introduced to the inlet zone of the bioreactor. Anoxic and/or aerobic conditions are provided in the reaction zone to cause the consumption of the contaminants by the bacteria on the supporting media and the suspended bacteria contained in the water to produce filterable water. This water is filtered at the filtration zone to produce a filtrate and a sludge, the filtrate having a total suspended solids of less than 10 mg/L with a flowrate of at least 2,000 L/h/m2 of filter area.
