CHEMICO-BIOLOGICAL SEWAGE TREATMENT PLANTS FOR PE <= 9.999
Journal Title: Civil and Environmental Engineering Reports - Year 2007, Vol 1, Issue 2
Abstract
Removal of nitrogen and phosphorus compounds is not required in the case of sewage treatment plants serving the settlement units of up to 9.999 citizens and not charging treated sewage into staying waters. Therefore, it is possible to reduce the range of water treatment to merely two requirements: the BOD5 and the concentration of suspended solids. It gives a possibility to use another technological solution in such sewage treatment plants. As a result, due to chemical pre-treatment, size of biological reactors can be substantially reduced. Such approach is justified not only by technical, but predominantly by economical issues.<br/><br/>
