Conditioning Process of Fresh Activated Sludge
The effect of polyelectrolytes; cationic and anionic charges and coagulants have been investigated for fresh activated sludge at different concentrations and pH values in a comparative fashion. The results from the experiments indicate that the cationic polyelectrolytes have a significant effluence on the sludge characteristic, degree of flocculation and water quality such as turbidity and SVI....
متن کاملUltrasonic monitoring of fish thawing process optimal time of thawing and effect of freezing/thawing.
INTRODUCTION Fish quality is traditionally controlled by chemical and microbiological analysis. The non-destructive control presents an enormous professional interest thanks to the technical contribution and precision of the analysis to which it leads. This paper presents the results obtained from a characterisation of fish thaw-ing process by the ultrasonic technique, with monitoring thermal p...
متن کاملImprovement of Rooster Sperm Quality by Adding Different Levels of Naringenin after Freezing-Thawing Process
Artificial insemination is a reproductive technology that uses the best male breeders. Successful artificial insemination is affected by several factors, one of the most important and most one is the availability of fertile sperm after the freezing-thawing process. The purpose of this study was to investigate the effect of different concentrations of naringenin after the freezing process. Sp...
متن کاملA modified oxic-settling-anaerobic activated sludge process using gravity thickening for excess sludge reduction
Oxic-settling-anaerobic process (OSA) was known as a cost-effective way to reduce the excess sludge production with simple upgrade of conventional activated sludge process (CAS). A low oxidation-reduction potential (ORP) level was the key factor to sludge decay and lysis in the sludge holding tank of the OSA process. However, the ORP control with nitrogen purge or chemical dosing in the OSA pro...
متن کاملProgress in Hydrolysis of Excess Activated Sludge by Additional Enzymes
Additional enzymes pretreatment technology can promote the hydrolysis of excess activated sludge, while increasing gas production. Single enzyme pretreatment of sludge, alkaline protease has a better effect of hydrolysis. The optimum working conditions for alkaline protease: pH value of 8.0, the solid-liquid ratio of 1:4, the enzyme concentration of 2%, the working temperature of 55°C, reaction...
