Basic Examination on Inclusion Immobilization Method of Actinomycete Suitable for Continuous Treatment of Highly-concentrated Wastewater

Abstract

There are growing concerns about severe water shortages in recent years. One of the factors of the water shortages is the recurrent depletion of dams caused by extreme little rain due to climate change. At present 90% of organic effluent treatment used in the aeration tanks at sewage treatment facilities is activated sludge method. The process has to include dilution in pretreatment because there is a limitation in processable concentration. This dilution process has caused many shortcomings, such as water waste, prolonged treatment time and expansion of facilities. This study aimed at continuous treatment over long periods by inclusion immobilization method with the focus on actinomycetes which can treat highly-concentrated wastewater. The result showed that the continuous treatment by inclusion immobilization method lasted for one month with added inclusion at intervals of fifteen days, and it can be a new treatment method.
