The purpose of this study was to conduct a literature review determine the understanding current research on use Cassava Peel (CP) in field wastewater treatment, especially as coagulant. This reports types coagulant modification CP, coagulants characterization CP for each modification, performance under various conditions, and applications treatment. takes references from 51 articles period 201...

This paper reports the potential of watermelon seed as a natural coagulant for water treatment. It was aimed at identifying watermelon seed as a possible replacement for alum and other synthetic polyelectrolytes in treating water. Laboratory scale studies using jar test experiments were performed on medium turbid water to determine the effect of dosage, pH stirring time and speed on coagulation...

The efficiency of Moringa oleifera (MO) seeds as a natural coagulant in the coagulation/flocculation process, followed by nanofiltration (NF) for the removal of cyanobacterial cells and cyanotoxins is investigated. "Synthetic water" prepared for the tests comprised de-ionized water with an inoculum of microcystis protocystis cells to obtain turbidity within the 50-450 NTU range. Methodology fol...

hlorine is the most widely used oxidant in the United States for water disinfection. But chlorine reacts with the natural organic matter (NOM) that remains after treatment and forms halogenated by-products. Only some of these by-products have been identified, such as trihalomethanes (THMs) and haloacetic acids (HAAs), which are suspected to be human carcinogens. In 1979 the US Environmental Pro...

The aim of this study is to develop novel composite coagulants that are versatile and effective in removing natural organic matter from water. Herein, novel polyaluminum chloride-chitosan composite coagulant was prepared by combining the two reagents at different chitosan/aluminum ratio. The coagulation performance was tested using two different water sources (synthetic water containing 10 mg.L...

the removal of organic precursors of disinfection by-products (dbps), i.e. natural organic matter (nom), prior to disinfection is considered as the most effective approach to minimise the formation of dbps. trihalomethanes (thms) as the main group of dbps are categorized and considered to have the potentiality of increasing the rate of liver, kidney and cns adverse effects. this study which pre...

in the current study, the efficiency of starch and plantago ovata extract as coagulant aids is compared in water turbidity removal. the coagulant is ferric chloride and the experiments are run in two ranges of ph 7 and 8. the achieved results of turbidity removal in different turbidity levels of 100, 50 and 20 ntu caused by different concentrations of starch and p.ovata as coagulant aids besid...
