The effluents, which are formed from the waste in the process of production of yeast and molasses, contain a large amount of colouring substances (melanoidins, etc.) and can give dark brown painting to the effluent leading to high organic load on the

The digestion of baker’s yeast wastewater was monitored by gas production intensity and composition of gaseous and liquid phases. Favorable coexistence of sulfate reducing bacteria and methanogens was explained by the presence and metabolism of tri

The wastewater from baker’s yeast production contains above-average concentrations of organic pollutants (25 000 mg/L total chemical oxygen demand, TCOD), nutrients (1500 mg/L Ntot, 100 mg/L Ptot) and sulphate (2900 mg/L SO4 � ). Baker’s yeast

Anaerobic digestion of distillery waste was studied in a mesophilic two-stage system consisting of an anaerobic filter (AF) and an upflow anaerobic sludge blanket (UASB) reactor. The experiments were conducted with hydraulic retention times (HRT) ran

The most critical issue in municipal waste management in Estonia is the biodegradable fraction because the source sorting and central collection and treatment of that fraction is neither economically nor environmentally cost effective. Over the last

During the last 5 years, four types of wastewaters from the food industry (yeast, cheese whey, distillery, vegetable oil) with different technological schemes of anaerobic mesophilic digestion (one or two stages) and different types of reactors (cont
