Wastewaters from the food and beverages industry, the pulp & paper industry and the chemical industry are highly loaded with organic pollutants and can be treated advantageously by means of anaerobic processes.
Aerobic treatment converts the organic pollutants (COD, BOD) in wastewater into a fair amount of excess sludge, and oxidizes the rest with oxygen (air) to carbon dioxide. This causes high operating costs for sludge treatment and disposal and for aeration, so that anaerobic treatment systems are normally to be preferred. The aerobic process however removes more pollution, so that it is always needed as a complementary polishing treatment, if...
