Climate change and human actions will exacerbate eutrophication cases in inland waters. By external or internal inputs, there be an increase nutrient concentrations those systems worldwide. Those nutrients bring faster trophic changes to waters possible health recreational advisories. A novel approach using a floating filtration system, silt curtain, geotextiles (woven non-woven) is under inves...

The polysaccharides and proteins of various seeds have bioflocculant properties. The performance of naturally occurring Strychnos potatorum was evaluated against the chemical coagulant alum. The study involved extensive jar test experiments using Strychnos potatorum suspension and alum solution either independently or in combination with spiked turbid water prepared in the laboratory. It was ob...

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...

The search for alternative solutions sustainable management of faecal sludge in the area dewatering with biocoagulants/bioflocculants remains unfulfilled. Some available and accessible indigenous plants northern part Ghana have been characterised subsequently evaluated their suitability use as biocoagulant/bioflocculants. Yila (Crossopteryx febrifuga) Voulo (Grewia mollis) were used this study....

BACKGROUND Electrocoagulation is a technique involving the electrolytic addition of coagulating metal ions directly from sacrificial electrodes. These ions coagulate with turbidity agents in the water, in a similar manner to the addition of coagulating chemicals such as alum and ferric chloride, and allow the easier removal of the pollutants. Purpose of this study was to conduct experimental in...

the effluent quality of a sewage treatment plant using activated sludge process and finally secondary treatment depends on the flocculation efficiency and settling of the flocs. the survey of various treatment processes in water and wastewater treatment shows that temperature and ph are the important factors affecting efficiency of flocculation and settling properties. this study was performed ...

The plastic recycling industry generates a high volume of wastewaters. In this study, an unprecedented use Moringa oleifera and tannin (Acacia mearnsii bark) associated with magnetite was proposed for the treatment these response surface method (RSM) central composite rotational design (CCRD) methodology applied to optimize influence operational variables (pH, temperature, electrical conductivi...

Turbidity (T) has been widely used to detect the occurrence of pollutants in surface water. Using data collected from January 2013 to June 2014 at eleven sites along two rivers feeding the Taihu Basin, China, the relationship between the concentration of five metals (aluminum (Al), titanium (Ti), nickel (Ni), vanadium (V), lead (Pb)) and turbidity was investigated. Metal concentration was deter...
