Sewage Treatment Plants Treatment Process Performance
1. Determination Of Per Capita Load & Water Consumption In Sewage Design
Determine the actual loading of various parameters in raw sewage e.g. BOD5, SS, COD, TKN, P, NH3 and oil and grease as well as determine the per capita loading and water consumption in sewerage systems by per capita organic loading, sewage generation quantity and study the strength of untreated sewage.
V-notch weir installed at inlet of STP for flow measurement
2. Inflow And Infiltration In Sewerage System
Investigate the causes and associated relationship between the quantity of in flow and infiltration in the sewer system. The study shall also derive the relation of inflow and infiltration to the design peak flow. Verify infiltration rate and peak flow factor "K" and determine whether they are acceptable for local conditions and to evaluate the flow characteristics.
3. Cost effective Upgrading Techniques of Oxidation Pond System
Investigate and identify cost effective methods of oxidation ponds upgrading. The study proposed to install baffles to improve hydrodynamic flow in the oxidation pond.
4. Application Of Magnetic Technology In Assisting Sedimentation Of Sewage
To study the feasibility of using magnetic technology in assisting sedimentation of suspended particles and to study the effect of magnetic fields to other physical parameters of sewage i.e. pH, Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD).
1. Application Of Bio-Chemical Products In Assisting/ Improving Treatment Performance Capability Of Sewage Treatment Plant
Investigate the expected effect to existing biological process and to the surrounding receiving water. To select five products based on their potential usage and economic considerations. Identify the most optimum operating conditions, application method and any by products. Carry out field test of each selected product.
2. Waste Stabilization Pond (WSP) Upgrading For Organic And Nutrient Removal Of Municipal Wastewater
To study the available technologies and processes in order to upgrade WSP. Optimizing the hydrodynamic patterns in upgraded pilot scale WSP for optimum retention time using computational fluid dynamics. Studying microbial transformation in upgraded WSP for both organic nitrogen. Proposing process and design criteria for upgraded WSP based on COD fractionation.
3. Self- Purification Capability Of Malaysian Rivers And Sewage Loading -Purify Or Pollute
Investigate various river systems in Malaysia and systematically monitor the pollutant levels and its self-purifying capacity. To review available water quality data and identify ultimate waste assimilative capacity of Sg. Skudai. Utilizing mathematical models to predicts the mixing and dilution of sewage treatment plant effluent discharge. Development of hydrodynamic and water quality model and demonstrate the application of the developed model.
4. Study On The Permissible Limits Of Industrial Effluents Into The Sewerage System In Malaysia
To study critical parameters and the effects of industrial effluent parameters to the domestic wastewater treatment plants. Identify the types of industries, suggest tariff charges and legal amendment needed before discharging critical parameters as well as pre-treatment systems needed for the industries before discharging into sewerage system.
5. Sewage Effluent Reuses-Potential Application In Malaysia
To identify the potential users for sewage effluent reuse and their required quality, including the most cost effective method to improve the quality of sewage effluent for suitable reuses. Membrane technology method of wastewater reclamation has been successfully experimented at Shah Alam public sewage treatment plant.
