This study investigates the hypothesis that the mechanisms of chemical coagulationflocculation and electrocoagulation produce specific imprints in nature, and the structure of sludge aggregates-floccules (flocs). Scanning electron microscopy (SEM) methods were used to produce 480 images of 32 types of wastewater sludge. The analyzed sludge was obtained by chemical coagulation and electrocoagula...

This research aimed to investigate the performance of seeds extract Moringa Oleifera (MO) as an eco-friendly coagulant and alternative practice in enhancing primary domestic wastewater effluent treatment by coagulation/flocculation, sedimentation. The were dried, crushed, sieved, content oil was extracted with n-hexane a solvent employing soxhlet apparatus (electro thermal) then used residue co...

The goal of this study was to investigate the performance coagulation-flocculation, and sedimentation tests reduce contaminant concentrations in domestic wastewater ecologically acceptable levels. were performed at (ONEE) laboratory using a jar test apparatus (GPB FLCDidatec, France) for enhancing primary treatment effluent from plant Ain Aouda City, Rabat, Morocco. Aluminum sulphate Al 2 (SO 4...

Currently with the progression of the pollution in water sources, considerable attention has been given to the application of membrane filtration technology using microfiltration or ultrafiltration membranes to the surface water treatment as an alternative to conventional coagulation sedimentation and sand filtration. The microfiltration and ultrafiltration membranes are appropriate for complet...

Hagfish slime is an ultra dilute, elastic and cohesive hydrogel that deploys within milliseconds in cold seawater from a glandularly secreted exudate. The slime is made of long keratin-like fibers and mucin-like glycoproteins that span a network which entraps water and acts as a defense mechanism against predators. Unlike other hydrogels, the slime only confines water physically and is very sus...

The objective of this research was to optimize the coagulation-flocculation process for abattoir wastewater by utilizing a bio-coagulant derived from Carica Papaya seed (CPS). (CPC) extracted using 2M NaCl solution, and carried out bench scale jar test. Applying design expert (13.0.5.0), 23 full factorials with 5 center points, effects three factors: coagulant dosage (X1), pH (X2), temperature ...

This study explores the potentials of Brachystegia eurycoma coagulant (BEC) and Vigna subterranean (VSC) as natural organic polymers (NOPs) for decolourisation Crystal Ponceau 6R (AR 44) in wastewater. Materials characterisation studies were done on precursors. A detailed kinetics was employed. The procedures evaluated through time-dependent reduction concentration particles, with variation ind...

Resource reuse has become an important aspect of wastewater management. At present, use sludge in agriculture is one the major routes. Conventional municipal treatment does not involve any designated process for removal heavy metals, and these distribute mainly between effluent sludge. Enhanced metals during primary may decrease metal concentrations both from secondary promote long-term This re...

Heavy metals are one of the greatest elevating threat to mankind and other living organisms it is released into environment due increasing dumpsites, transports, industrial sectors. The wastewater containing heavy metal ions easily enters food chain through air, water, soil; results in bioaccumulation biomagnifications human beings. It causes severe chronic health disorders affecting nervous sy...

Xanthate is the most widely used and effective collector in flotation of sulfide minerals. However, residual xanthate wastewater may cause serious environmental pollution even human health hazards. At present, a variety treatment technologies have been developed to degrade pollutants wastewater, with aim meeting safe discharge standards. This work reviews research status recent years. Treatment...
