Reactor Application

Ammonium, a form of nitrogen, causes eutrophication and also can be toxic for fish. The existence of ammonium in surface water arises from human and animal waste, as well as from organic materials oxidation derived from industrial or residential wastewater. Consequently, wastewater with high ammonium content must be processed properly prior to disposal. One of the commonly used treatments for wastewater is attached biological wastewater treatment, which can be applied with a fixed bed reactor. Fixed bed reactor was being inoculated with ecotru bacteria which were fed with artificial wastewater containing ammonium of 50 mg NH4+-N/L. In this study, it was found that the microorganisms contained in ecotru are Geobacillus toebii bacteria. The ammonium removal efficiency was 99,63% and the way Geobacillus toebii contribute on ammonium removal was experimentally studied in this study.

The Relationship

The relationship between the filter media and the behaviour of anaerobic bacteria was studied using anaerobic fixed-bed reactors. At an HRT of 48 hours, the number of suspended acidogenic bacteria was higher than those attached to the filter media. On the other hand, the number of attached methanogenic bacteria was more than ten times as higher than that of suspended ones. The numbers of suspended and deposited acidogenic and methanogenic bacteria in the reactor operated at an HRT of 3 hours were almost the same as those in the reactor operated at an HRT of 48 hours. Accumulation of attached bacteria was promoted by decreasing the HRT of the reactor. The number of acidogenic bacteria in the reactor packed sparsely with the filter media was higher than that in the closely packed reactor. The number of methanogenic bacteria in the sparsely packed reactor was lower than that in the closely packed reactor.
