Grey water contains organic matter that is directly disposed to the environment without any treatment previously, will cause pollution and impacting life in water. Treatment can be done using microorganisms. One of its kind microalgae Chlorella sp. which utilizes as a source nutrients for growth. In this study, Kaldness 1 (K1) bio carrier was added medium attaching microorganisms Sequencing Bat...

The reduction and dehydration treatment of contaminated sediment from rivers lakes is a prerequisite for ensuring the subsequent safe disposal. In this study, micro-nano bubbles (MBs) technology was creatively proposed conditioning to improve its sedimentation performance. Orthogonal experiment single factor were conducted optimize factors such as bubble size, intake air volume time. effect ana...

Know days, pollution made by the wastewater in rivers and other water body’s is one of the main concerns of environmental engineers. Membrane bioreactors are one of the earliest methods for treating swage and also to produce water that is acceptable for reuse purposes. The term membrane bioreactor expresses a combination of activated sludge and membrane separation processes. The need to process...

In this study, granulated sludge synthesized in a sequence batch reactor (SBR) and then granulated sludge was transferred to continuous feeding and intermittent discharge (CFID) bioreactor. Two independent variables (air flow rate and hydraulic retention time (HRT)) were considered to optimize the process. Subsequently, long term performance (150 days) of the bioreactor was assessed by monitori...

A synthetic pharmaceutical manufacturing facility was experiencing recurring upsets of nitrification at its wastewater treatment plant. The main treatment train consisted of trickling filters followed by a conventional activated sludge process with ostensibly adequate treatment capacity (average F/M of 0.1, COD/MLSS-based). An evaluation of the plant’s operating conditions and performance indic...
