Determining the optimal dose of coagulant required to perform flocculation is critical in most water treatment plants’ planning and operation. This study implemented a 2k–p fractional factorial design experiments identify factors influencing color decrease wastewater from slaughterhouse. The variables assessed were velocity gradient, residence time, primary dosage, chlorine coagulation adjuvant...

Abstract Purpose In addition to agriculture, energy production, and industries, potable water plays a significant role in many fields, further increasing the demand for water. Purification desalination play major meeting need clean drinking Clean is necessary different areas, such as industry, food generation everyday chores. Design/methodology/approach The authors have used search engines like...

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...

The coagulation of isoelectric egg albumin solutions, on exposure to ultraviolet radiation, involves three distinct processes, (1) the light denaturation of the albumin molecule, (2) a reaction between the light denatured molecule and water which may be similar to heat denaturation but occurs at a lower temperature, and (3), the flocculation of the denatured molecules to form a coagulum. The li...

The use of ceramic low pressure membranes for drinking water production has been increasing in the past decades. However, fouling during membrane operations is still a challenging topic that requires attention and investigation. During filtration of surface water, a major contribution to fouling is attributed to the presence of dissolved organic carbon(DOC) and its fractions which comprise biop...

Thickener is a main and fundamental step in modern mining separation processes. In this research, the effectof flocculant consumption rate and feed solid concentration of settling rate of layers was studied with differentconcentrations in iron ore mine of Jalalabad, Zarand, Kerman, Iran. The experiments were performed in two1000 ml graduated cylinders (61 and 62 mm diagonal an...

Paint, tannery and textile manufacturing wastewaters contain highly toxic organic biorefractory compounds have adverse effects on human health. These effluents require efficient environment friendly solutions before being discharged. Jar-test experiments are conducted in order to assess the efficiency of a tannin-based polymer (TBP) treatment these industrial wastewaters.The results indicate th...

It is an important criterion the choice of lighting technique for industrial applications in water purification. In article it was examined research methods coagulation and flocculation process. Today, improvement these techniques use flocculants coagulants, which speed up process flocculation, are relevant. were considered as coagulants sulfuric acid salts Al2(SO4)3 FeSO4. noted advantage over...
