Coagulants can be extracted from vegetal material and applied in the treatment of wastewater. These coagulants are derived seeds, leaves, bark, roots fruits. This study focuses on use mucilaginous extract Stenocereus griseus (known as Cardón Guajiro) for removal biochemical oxygen demand (BOD5), chemical (COD), total solids, turbidity color domestic wastewater a pumping station city Cartagena (...

background; water treatment sometimes needs a coagulation and flocculation process to remove suspended and colloidal materials. inorganic coagulants used create concerns about pollution of the environment and harmful effects on the human’s health. the studies carried out previously indicated the capability of an active coagulant agent extracted from descurainia sophia seed to remove turbidity o...

The widespread use of reagent coagulation in the technology purification natural and waste waters is due to complexity chemical composition phase-dispersed state aqua systems these waters, on one hand, multifactorial action coagulants them, other. mechanisms interaction between pollutants wastewater which are different states include physicochemical phenomena coagulation, heterocoagulation, ada...

<p>Industrial wastewater has become a great concern due to high concentrations of several hazardous contaminants, particularly heavy metals. Heavy metal contamination and its consequences for human health the environment have gained interest in developing low-cost, long-term cleanup technologies. Biologically based treatment approaches being more effective than conventional methods are ge...

The use of Moringa oleifera seed in water purification has reduced the chemical-based coagulants which is detrimental to both human and livestock. This project aimed at testing microbial properties M. oil extract on some selected pathogens (Bacterial fungi). was extracted using Soxhlet apparatus with ethanol as solvents. Gas-chromatography-mass spectrometry (GCMS) analyses were carried out for ...
