Anaerobic Digestion Technology for Industrial Wastewater Treatment
نویسندگان
چکیده
Anaerobic digestion is the most suitable option for the treatment of high strength organic effluents. The presence of biodegradable components in the effluents coupled with the advantages of anaerobic process over other treatment methods makes it an attractive option. This paper reviews the suitability and the status of development of anaerobic reactors for the digestion of selected organic effluents from sugar and distillery, pulp and paper, slaughterhouse and dairy units. In addition, modifications in the existing reactor designs for improving the efficiency of digestion has also been suggested.

Anaerobic Biotechnology for Pharmaceutical Wastewater Treatment
The wastewater generated from the pharmaceutical industry contain high organic load and the treatment are primarily carried out using two major types of biological methods; aerobic and anaerobic. However, due to high strength, it is infeasible to treat some pharmaceutical wastewater using aerobic biological processes. As an alternative, an anaerobic process is preferred to remove high strength ...
متن کاملZero Valent Iron Significantly Enhances Methane Production from Waste Activated Sludge by Improving Biochemical Methane Potential Rather Than Hydrolysis Rate
Anaerobic digestion has been widely applied for waste activated sludge (WAS) treatment. However, methane production from anaerobic digestion of WAS is usually limited by the slow hydrolysis rate and/or poor biochemical methane potential of WAS. This work systematically studied the effects of three different types of zero valent iron (i.e., iron powder, clean scrap and rusty scrap) on methane pr...
متن کاملAnaerobic Wastewater Treatment Process
Anaerobic wastewater treatment differs from conventional aerobic treatment. The absence of oxygen leads to controlled conversion of complex organic pollutions, mainly to carbon dioxide and methane. Anaerobic treatment has favourable effects like removal of higher organic loading, low sludge production, high pathogen removal, biogas gas production and low energy consumption. Psychrophilic anaero...
متن کاملEvaluation of pre-treatment efficiency of fats, oils and greases using low frequency ultrasonic waves to accelerate the process of anaerobic digestion
Background and Objective: Hydrolysis of fat, oil and grease by ultrasonic waves is a pre-treatment method before anaerobic digestion which can change their physical, chemical and biological properties. The main purpose of this study was to investigate the efficiency of ultrasonic waves to improve the hydrolysis process and its use as an auxiliary substrate to increase the efficiency of anaerobi...

Worldwide, environmental regulatory establishments are setting strict standards for discharge of wastewaters from industries. Anaerobic digestion is an environment friendly technology to treat industrial wastewaters. Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen. For the treatment, cheese-dairy wastewater is taken...
