More than 40% of the homes in Georgia use onsite systems to manage household wastewater. Because of water quality concerns as the number on onsite systems increases, advanced wastewater treatment components to reduce biological oxygen demand (BOD), total suspended solids (TSS), and nutrients are more commonly used.. The objective of this study was to evaluate passive, low-maintenance onsite sys...

The effect of adding alum water treatment residues (WTR) on the methanogenic activity in digestion primary domestic wastewater sludge was evaluated through laboratory experiments sedimentation columns, using total suspended solids (TSS) concentrations from 0.37 to 1.23 g/L. addition WTR clarifiers can benefit its effluent quality terms colour, turbidity, chemical oxygen demand (COD), and TSS. H...

Decentralized treatment of stormwater runoff from heavily polluted surface can be a good solution for effective source control. systems (DS) and test procedures to monitor their performance, have been developed in recent years. At present Germany, only lab-based tests are officially established determine the removal efficiency Total Suspended Solids (TSS), situ monitoring is still lacking. Furt...

This paper presents a study on the use of best management practices (BMPs) for controlling nonpoint pollution in the Xikeng Reservoir watershed located in Shenzhen, China. A BMP treatment train design, including a pond, a wetland, and a buffer strip placed in series was implemented at the reservoir location. A separate grass swale was also constructed at the site. Low impact development (LID) B...

The removal of Total and Volatile Suspended Solids (TSS/VSS) was studied in a pilot-scale UASB (Upflow Anaerobic Sludge Bed) reactor treating settled sewage under subtropical conditions (Salta, Argentina). The effect of sludge bed height (hsb) and upflow velocity (Vup) on the removal of TSS and VSS was assessed. TSS and VSS removal efficiencies of up to 95% have been achieved when Vup ≤ 0.43 m/...

Government and NGO funded conservation programs are being implemented in developing countries with the potential benefit of reduced sediment inflow into fresh water lakes. However, these claims are difficult to verify due to limited historical sediment concentration data in lakes and rivers. Remote sensing can potentially aid in monitoring sediment concentration. With almost daily availability ...

Environmental monitoring through the method of traditional ship sampling is time consuming and requires a high survey cost. This study uses an empirical model, based on actual water quality of total suspended solids (TSS) measurements from the Prai River estuary Penang, Malaysia, to predict TSS based on optical properties of digital camera imagery. The proposed algorithm is based on the reflect...
