Mest indikken met zonne-energie
Om mestafzetkosten te verlagen kan de mest op het varkensbedrijf ingedikt worden. Mestsilo's kunnen hiertoe voorzien worden van een zonlichtdoorlatende afdekking. Hierbij wordt de verdamping gestimuleerd.
Control of calcium carbonate precipitation in anaerobic reactors
Anaerobic treatment of waste waters with a high calcium content may lead to excessive precipitation of calcium carbonate. So far, no proper methods were available to predict or reduce the extent of precipitation in an anaerobic treatment system. Moreover, it also was not clear to what extent precipitation in an anaerobic reactor can be tolerated be...
Impact of location of CaCO3 precipitation on the development of intact anaerobic sludge
The development of intact anaerobic granular sludge was studied in UASB reactors under varying conditions of CaCO3 precipitation and biomass yield. Varying precipitating quantities were obtained using different calcium concentrations in the influent and different biomass yields were obtained by feeding with completely or partly acidified substrate....
