Types of wastewater treatment technologies for facilities with a capacity up to 1000 m3/day

The article presents an algorithm of making a decision for choosing a technological scheme of wastewater treatment for facilities with a capacity up to 1000 m3/day. There are factors, which help to determine the scheme: plant performance, amount of suspended solids and indicator of wastewater pollution with organic compounds - biological oxygen demand. The best solution according to these parameters can be one or more from 14 considered options of technological schemes, that simplifies and speeds up the process of selecting and designing the main structures of a wastewater treatment plant.
