Abstract: The present invention relates to a process for the treatment of industrial alkaline streams comprising sulfide and carbonate, comprising the steps of: a) providing an industrial alkaline stream comprising sulfide and carbonate; b) supplying the industrial alkaline stream to a bioreactor comprising sulfide oxidizing bacteria and removing sulfide from the industrial alkaline stream by subjecting said stream to sulfide oxidizing bacteria in the presence of oxygen, and supplying a pH adjustment agent to the bioreactor to maintain a pH in the range in the range 8 to 11, to oxidize the sulfide to elemental sulfur, c) withdrawing from the bioreactor a treated industrial alkaline stream comprising elemental sulfur, wherein a portion of the sulfide oxidizing bacteria is removed from the bioreactor and mixed with the industrial alkaline stream prior to supplying the industrial alkaline stream to the bioreactor in step b).

Abstract: The invention relates to a process for producing a microbial storage compound, in particular polyhydroxyalkanoate, using micro-organisms capable of accumulating such microbial storage compound, wherein such micro-organisms are selected and the microbial storage compound is accumulated by carrying out the so-called feast phase of the selection step and the accumulation of the microbial storage compound in selected micro-organisms in the same reactor and carrying out the so-called famine phase of the selection step in a separate, smaller, reactor.

Abstract: Hydrogen sulfide can be removed from a liquid effluent of an anaerobic reactor, by subsequently: —contacting the effluent liquid in counter current with a treated product gas of the anaerobic reactor to absorb hydrogen sulfide in the gas, —collecting the desulfurised effluent liquid after said contacting, —discharging at least part of the collected desulfurised effluent recirculation liquid as a treated effluent. To a remaining part of the desulfurised effluent waste water can be added and mixed, and the mixed water can be fed to the anaerobic reactor. Spent gas of the contacting step can be combined with sulfide-containing product gas of the anaerobic reactor and treated by desulfurisation.

Abstract: Wastewater containing a significant level of dissolved readily biodegradable organic compounds matter, such as short-chain fatty acids, and ammonia can be efficiently treated to remove most or all of the organic compounds and the ammonia, with the production of microbial storage compounds such as polyhydroxylkanoates, by (i) subjecting the wastewater storage compound-accumulating microorganisms (SCAM) in the presence of oxygen, (ii) subjecting at least part of the resulting partly treated wastewater to ammonia-oxidising microorganisms (AOM) in the presence of oxygen and (iii) feeding a gas containing molecular carbon dioxide produced during step (ii) to step (i) so as to lower the pH in step (i).
