Financial Prospects in the Application of Decanter System for the Treatment of Sludge Wastewater in Water Treatment Plant System

This study focuses on the financial aspects in the application of decanter system for the treatment of sludge wastewater with a case study of Buaran Water Treatment Plant System. Engineering cost estimates was made to predict investment of the decanter system as well as their operational cost. Financial analysis was then developed by using a mathematical model to look at a bankability of the investment. With a reasonable water tariff it appears that the application of decanter system for the treatment of sludge wastewater is financially prospective and bankable, and is thus environmentally very beneficial.
