The evaluation of metham sodium and dichlobenil impacts on activated sludge nitrification
… and oxygen concentrations typically found in sewage collection systems and so undergoes little degradation after application. Powdered activated carbon (PAC) is effective in absorbing metham sodium from raw sewage. In bench scale reactors, application rates of 10 mg PAC per 1 mg metham sodium …

Removal of nutrients and heavy metals from domestic and industry using botryococcus sp.
Microphytes or microalgae are the most basic food source of many types of organisms on earth and blooms during the presence of dissolved inorganic phosphorus. Wastewater is a body of water that is dangerous to organic life forms when consumed or used. It contains many pollutants that can cause …

Study of recycled concrete aggregate as filter media for phosphorus removal in synthetic wastewater
Phosphorus is one of the key nutrients that lead to eutrophication in surface water. However, existing conventional wastewater treatment systems for removing phosphorus are expensive and complex. Recycled concrete aggregate (RCA) may be an alternative solution for phosphorus removal. It can reduce …

Phycoremediation using botryococcus sp. as nutrients removal in organic wastewaters coupled with hydrocarbon production
Rapid population growth and industrial development are expected to contribute extremely to the world environmental crisis due to the excessive wastewater generation, global warming, climate change and increased use of petroleum fuels. In response to the problems, new technology via phycoremediation …

Audio for Flow Monitoring in Wastewater
Digitalisation can greatly improve process control in wastewater systems but requires increased sensing and monitoring that can provide actionable information. Audio is underutilised as a sensor input despite fluid flow naturally generating sound through different physical processes. This thesis …
