There are various kind of wastewater treatment method though, this article is about coagulating sedimentation. This is a method which is based on flocculation treatment.   ■ Coagulating sedimentation method   This is a method to add inorganic flocculant (inorganic coagulant) or polymer flocculant into small particles such as colloidal particles in wastewater, and to […]

In wastewater treatment, wastewater purification is done by settling particles in wastewater as sediment. However, wastewater cannot be purified unless particles in the water is settled. There is a treatment method called flocculation treatment and it separates particles in wastewater by settling them. Although particles in wastewater can settle down when their size are large, […]

There are various activated sludge methods in wastewater treatment though, membrane bioreactor method is one of activated sludge method where treated wastewater and activated sludge are separated by microfiltration membrane or ultrafiltration membrane in stead of conventional settled tank. It is often called MBR method or just MBR as well. Other than that, it is […]

There are various activated sludge methods in wastewater treatment though, this article is about fluidized bed method which is one of three types of biofilm processes.   ■ About  Fluidized bed method   This is a method to purify wastewater by filling carriers (contact materials, filer materials) in reaction tanks and generate biofilm, which is […]
