Industrial effluents are a menace to the environment and the fact that their characteristics vary from industry-to-industry only adds to the complex challenge they offer to the engineers and scientists. Resource-efficient and environment-friendly solutions to this hazard are a call of the hour. Coagulation, by synthetic chemicals, has been used as a cost-effective and efficient method for manag...

In this present study the dissolved air flotation (DAF) system was investigated for the treatment of Kermanshah Oil Refinery wastewater. The effect of three parameters on flotation efficiency including of flow rate (outflow from the flotation tank), saturation pressure and coagulant dosage on chemical oxygen demand (COD) removal was examined experimentally. All the experiments were done under a...

Plantago ovata is a medicinal plant of plantain, Plantaginaceae, family used to treat intestinal disorders and stomach diseases. P. ovata grain has relieving effects and healing inflammation and irritation of the mucous layer of stomach and duodenal ulcer. Beside the medicinal benefits, this plant is useful for water turbidity removal. Coagulation and flocculation are important processes in wat...

Pumice and the Moringa oleifera (MO) seed were investigated as alternative natural materials for drinking water treatment based on problems identified at the Stretta Vaudetto water treatment plant in Eritrea. Lab and pilot scale studies showed that pumice was a suitable alternative material for dual media filtration. Conversion of the sand filters at Stretta Vaudetto to pumice-sand media would ...

The present study is focused to optimize the coagulation process for treatment of water sourced from the Palar River Basin and supplied to the Vellore Municipality. The research was progressed to evaluate the water treatment efficacy of natural coagulant i.e. moringaoleiferaseed, available locally in abundance, as well as conventional coagulants viz. alum and ferric chloride. Primly the basic o...

AIMS The aim of this work was to analyse the coagulant and antibacterial activities of lectin isolated from Moringa oleifera seeds that are used for water treatment. METHODS AND RESULTS The water-soluble M. oleifera lectin (WSMoL) was separated from nonhemagglutinating components (NHC) by chitin chromatography. WSMoL fluorescence spectrum was not altered in the presence of ions that are often...

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...
