This study aimed to investigate the efficiency of the enhanced coagulation (EC) process for the simultaneous removal of turbidity and humic substances (HS) from raw water from the Sanandaj Water Treatment Plant (SWTP). This study was conducted on a laboratory scale using a jar test device and ferric chloride (FeCL3) as the coagulant. Accordingly, the effects of pH and coagulant dosag...

Background: Coagulation is a treatment procedure for metalworking fluids (MWFs). This study aimed to optimize coagulation using four coagulants and compare the results. Methods: In this research, the outputs of a coagulation procedure in chemical oxygen demand (COD) removal, turbidity, and the release of oil were investigated using four coagulants, ferric chloride (FeCl3), ferric sulfate (Fe2(...

Carbonaceous aerosols including organic carbon and black carbon have significant implications for both climate and air quality. In the current global climate or chemical transport models, a fixed hydrophobic-to-hydrophilic conversion lifetime for carbonaceous aerosol (τ) is generally assumed, which is usually around one day. We have implemented a new detailed aging scheme for carbonaceous aeros...

The production of biodiesel through the transesterification method produces a large amount of wastewater that contains a high level of chemical oxygen demand (COD) and oil and grease (O&G). In this study, coagulation was adopted to treat the biodiesel wastewater. Two types of coagulation were examined using a standard jar test apparatus, i.e. polyaluminium chloride (PAC) and aluminium sulphate....

The use of coagulation-flocculation process as means wastewater treatment is gradually becoming more popular. This research work to evaluate the efficiency in abattoir effluent. Samples effluent were collected from a slaughterhouse at Ede, Nigeria, and Alum was used physico-chemical bacteriological analyses untreated treated carried out these determining process. values obtained (from analyses)...

Coagulation process is an essential part of drinking water treatment operations. The jar test is a widely-used laboratory procedure to determine the quantity of coagulation chemical dosages for water treatment plants. However, the test is not effective for real-time control of this process due to the nonlinear behaviour and rapid variations of water quality parameters. In this study, empirical ...
