In this work, the coagulation-flocculation and electrocoagulation treatments were compared in removal of pollutants from wastewater Conchucos slaughterhouse, Lima. For treatment, we worked with 4 independent variables their respective experimental ranges, coagulant dose (600-1000 mg / L), flocculant (4-8 mg/L), fast stirring speed (250-350 rpm), slow (80-100 for parameters rpm) time (15-30 rpm)...

The aim of this work is to investigate the enhancement UVC-based tertiary treatments; for purpose, real wastewater treatment plant (WWTP) effluent was spiked with a model pollutant, namely acetaminophen. UVC irradiation resulted in some photodegradation acetaminophen, which enhanced upon addition hydrogen peroxide (11 mM), but higher amounts oxidizing agent no significant acceleration process. ...

Flocculation is a key unit operation in domestic and industrial water treatment, beneficiation of minerals, dewatering of sludges and in many industrial solid-liquid separation processes. Coagulants and flocculants are commonly employed as additives to induce aggregation and improve subsequent filtration or dewatering operations. The characteristics of these additives have a strong influence on...

Introduction: Textile wastewaters from dyeing and finishing processes are heavily polluted with dyes, textile auxiliaries and chemicals and have a broad range of pH, high COD concentration and suspended particles. In this study, the efficiency of color and turbidity removal from synthetic textile wastewater samples were investigated by combined process of coagulation/ flocculation and electron ...

Point of use (POU) household water treatment is increasingly being adopted as a solution for access to safe water. Non-tuberculous Mycobacteria (NTM) are found in water, but there is little research on whether NTM survive POU treatment. Mycobacteria may be removed by multi-barrier treatment systems that combine processes such as coagulation, settling and disinfection. This work evaluated remova...

Plant-derived coagulants have exhibited a good potential in wastewater treatment due to their “green” characteristics, high coagulating-flocculating activity, cost-effectiveness, and biodegradability. Nevertheless, research studies focused mainly on bench-scale experiments; pilot-scale full-scale simulations are still limited. Herein, we firstly report study of real domestic textile using Cassi...

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 city of Bekasi is experiencing rapid development so the demand for water increasing. To increase service coverage and meet drinking needs people City with a quality that meets Minister Health Regulation No. 492 2010, it planned to up rate capacity Teluk Buyung 4 WTP has 300 L/second raw source, namely West Tarum Secondary Channel. use design criteria from Equivalent evaluation, 3 literature...
