Joint Treatment

The National Board of Waters in Finland has proposed a study on the joint treatment of industrial and municipal wastewaters of the City of Kotka. This study is of great interest due to the large forest products industry and food industry in Kotka. All of the wastewaters from the forest products and the food industry and the municipal sewage have been found to be suitable for biological treatment, which makes the joint treatment applicable. An activated sludge process is selected because it takes advantage of the large amount of nutrients in the municipal sewage and it has proved to be the most efficient treatment method for forest industry wastewaters. However, municipal wastewater contains more nutrients than needed for the biological process, which can cause eutrophication problems in the watercourse. To reduce the pollution caused by the nutrients, chemical treatment of the wastewater is also proposed in the joint treatment. It was concluded that the joint treatment of wastewater is economically, technically and environmentally the best way to arrange wastewater treatment for the industry and the city.

Treating Effluent

The requirements imposed on the Finnish forest products industry by the water authorities have focused on the reduction of BOD and suspended solids in the wastewaters. The industry has tried to comply with these requirements, first through internal measures such as process changes and closed systems. When these have not been sufficient, external treatment has been resorted to. The Wilh. Schauman Company in Jakobstad has chosen activated sludge with extended aeration from among the available methods for treating effluent. The plant has operated since the beginning of 1986 with extremely good results. In addition to the reduction of BOD and suspended solids, there has been a marked decrease of chlorinated phenols. Chlorinated substances with higher molecular weight are also removed during the process.
