  • System for biological treatment of water and wastewater
    Patent number: 9181117
    Abstract: A system and method for treatment of ammonia-containing raw water from low-temperature sources is designed to provide optimum treatment conditions, particularly temperature of the raw water in the bioreactor(s) containing nitrifying bacteria. The raw water supply is split into two streams, of which one stream is heated before remixing with the other stream. The split-stream heating is optionally supported by the provision of a retention tank on the heated-water stream. A three-way valve is provided to control compressed air supply to be mixed with the raw water in dependence on water level in the bioreactor.
