Abstract
The present invention relates to an anaerobic reactor for the treatment of industrial and other wastewaters at psychrophilic temperatures, the reactor comprising a mixing chamber in which is located, during use, a granular sludge fluidised bed, the reactor further comprising a biofilm chamber fed from the mixing chamber and housing a biofilm colonised pumice-based carrier material, and a separation chamber in fluid communication with the biofilm chamber and in which treated effluent and biogas produced within the reactor are separated.
Claims23
An anaerobic reactor for treating liquid effluent at psychrophilic temperatures, the reactor comprising a hydroxyl, aluminum, manganese, sodium, potassium, calcium, iron and/or magnesium ion releasing biofilm carrier material for effecting, in use, the biologically-mediated attenuation of phosphate from the effluent.
A method of anaerobic treatment of a liquid effluent at psychrophilic temperatures, the method comprising the step of introducing hydroxyl, aluminum, manganese, sodium, potassium, calcium, iron and/or magnesium ions into the effluent in order to effect biologically-mediated attenuation of phosphate from the effluent.
