Treatment plants are faced with the challenge of stricter regulations and higher standards for finished water quality. New developments in control strategies and instrument design have overcome some of the previous limitations of monitoring and controlling the coagulation process. An online floc analyzer provides valuable information on the dynamics of particle aggregation subsequent to coagula...

Arsenic is a carcinogenic metalloid that is currently regulated in drinking water. The levels of arsenic in finished water in an existing water treatment plant are exceeding the current regulation of 10 μg/L. One of the available technologies for arsenic removal from groundwater is adsorption onto coagulated flocs and in this field, ferric chloride is the most commonly used coagulant for arseni...

One of the major sources, which wastes the environment is the wastewater produced from the human activity. At present, in order to decrease waste hazards and to restrict the resulted effects on the environment, investigators studying the possibility of using new methods and materials to treat wastewater. Coagulation and flocculation process are physical-chemical methods that widely used in the ...

scarcely pharmaceutical applications. Recent investigations state its utility in dissolution enhancement of poorly soluble drugs, amorphous state stabilization and extended drug release. To broaden the applications of MC as a pharmaceutical excipient, need has been felt to test its antigenicity owing to its proteinic nature. In silico antigenicity screening has been carried out to enable its us...

chemical wastewater treatment is one of the attracting and common methods for wastewater treatment among the currently employed chemical unit processes. the use of coagulant-flocculant compound is one of the efficient methods for separating of paint and recovery of water. in this research, it was introduced and the effect of ph on removal of solid content from solution was studied experimentall...

BACKGROUND Laparoscopic prostatectomy (LRP) may activate clotting system influencing the risk of perioperative thrombosis in patients with prostate cancer. Moreover, different anaesthetic techniques can also modify coagulant factors. Thus, the aim of this study was to investigate the effects on pro- and anti-coagulant and fibrinolytic factors of two established types of anaesthesia in patients ...

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...

In this work, the effectiveness of removing colour and total suspended solid (TSS) from complex organic particulate artificial sewage (COPAS) via coagulation process was studied. Organo-floc (OF), a tannin-based coagulant derived plant used as coagulant. OF applied in jar test experiment at various dosages 57 rpm for 5 min, 30 min sedimentation time to find out optimum dosage TSS removal. Zeta ...

Problem statement: Turbid waters, containing colloidal particles, are normally treated by coagulation-flocculation followed by clarification. Ferric chloride and alum, which are the most common types of coagulants in water treatment plants of Iran as well as many other countries, were investigated with the aim of determining their capabilities to reduce turbidity of drinking water. Turbidity wa...
