A new kind of flocculants, named Polymer Silicate Phosphate Ferric Sulfate(PSPFS), was synthesized by ferrous sulfate used as the main material and activated silicic acid as additive. In this paper, High-Viscosity Oil Refining wastewater from Liaohe Petrochemical Corporation was the treatment object. Overall, the influencing factors and synthesis technology conditions of PSPFS were determined b...

the aim of this research was optimization of refining of raw sugarcane juice using bentonite for production of natural liquid sugar or cane honey. non-sugar substances of raw sugarcan juice contains: colorants, polysaccharides, gums, proteins, etc that affect on efficiency and quality of the final product and should remove from raw sugarcane juice. gelatin is a protein which is used as an aid c...

in addition to technical, economic and environmental factors, public acceptance plays an important role in successful treated wastewater reuse projects. the aim of this study is to evaluate yazd citizens’ awareness regarding water and wastewater issues and public acceptance towards wastewater reuse by questionnaire-type survey. for this purpose 250 questionnaires were distributed and filled out...

Objective: More and more non-degradable substances in wastewater along change of life style, however, traditional handling agent has not met the demand of wastewater treatment, so it is very important to study for new highefficient flocculent. Method: Sifting out six microbes after testing and inoculation, and then testing for wastewater quality having three contents, this found that mix bacter...

The biological treatment of wastewater discharged from a biodiesel fuel (BDF) production plant conducting alkali catalysis transesterification was investigated. BDF wastewater has a high pH and high hexane-extracted oil and low nitrogen concentrations, and inhibits the growth of microorganisms. The biological treatment of BDF wastewater is difficult because the composition of such wastewater is...

A review of the literature published in 2014 on topics relating to public and environmental health risks associated with wastewater treatment, reuse, and disposal is presented. This review is divided into the following sections: wastewater management, microbial hazards, chemical hazards, wastewater reuse, wastewater treatment plants, wastewater disposal, and sludge and biosolids.

enzymatic extract preparation from pseudomonas aeruginosa km110 under accession no. hq730879 with lipase activity (0.3 u/ml), was used to perform enzymatic hydrolysis pretreatment of a synthetic dairy wastewater with 1000 mg/l total fat content. the pretreatment was optimized for 48 h hydrolysis time, at 45æ% c with 10% v/v enzymatic extract. the biological treatment of synthetic dairy wastewat...
