electroplating industry wastewater (eiw) characterized by high chemical oxygen demand (cod) is a big source of water and air contamination with heavy metals. the formation of cyanide complex with heavy metals is responsible for its elevated cod. the concentration of heavy metals in eiw can be removed by the use of different precipitating agents (sulfide and hydroxide). but the major bottleneck ...

introduction: the objective of this study was, wastewater quality investigation and removal efficiency of contaminants from the wastewater tile factory by using  coagulants includes ferric chloride, ferric sulfate and ferrous, aluminum sulfate and poly aluminum chloride in order to reuse it in the processing line. methods: this is an applied study. with regard to shiftwork schedules of the fact...

Textile industry can be classified into three categories viz., cotton, woolen, and synthetic fibers depending upon the used raw materials. The cotton textile industry is one of the oldest industries in China. The textile dyeing industry consumes large quantities of water and produces large volumes of wastewater from different steps in the dyeing and finishing processes. Wastewater from printing...

Starch is an important biopolymer, which is used in various branches of industry including food technology, mining, textile and paper industry. The divergence in applications causes the need of different technological parameters, such as granularity, solubility, viscosity, molecular weight. These features are controlled by molecular structure of starch, which is complex and covers all levels of...

Biohydrogen production from starch wastewater industry via up-flow anaerobic staged reactor (UASR) was investigated. The reactor was operated at a hydraulic retention time (HRT) of 0.28 d, and different food to micro-organisms ratios (F/M) of 0.5, 0.9, 1.4, 1.9 and 2.8 g-COD/g-VSS.d. Peak hydrogen production rate (HPR) of 246 mmol-H2/L.d was observed at F/M of 1.4 g-COD/g-VSS.d. Artificial Neur...

High amounts of industrial wastewater are generated by the ever-growing demand and production paint coating materials. These effluents have negative effects on human health environment. The source highly influences properties, composition, content pollutants. manufacturing coatings uses huge volumes water chemical reagents, consequently producing heavily polluted wastewater. This review is focu...

BACKGROUND Carbapenemase-producing Enterobacteriaceae (CPE) are an emerging infection control problem in hospitals worldwide. Identifying carriers may help reduce potential spread and infections. AIM To assess whether testing hospital wastewater for CPE can supplement patient-based screening for infection prevention purposes in a hospital without a recognized endemic CPE problem. METHODS Wa...

Attempting to associate waste treatment to the production of clean and renewable energy, this research sought to evaluate the biological production of hydrogen using wastewater from the cassava starch treatment industry, generated during the processes of extraction and purification of starch. This experiment was carried out in a continuous anaerobic reactor with a working volume of 3L, with bam...

Present study dealt the removal of Cr(VI) in a tannery industry wastewater using rice husk silica powder as an adsorbent.The experimental investigations have been carried out by using rice husk silica powder for different adsorption dosage, different contact time and different pH against the initial Cr(VI) concentration of 292 mg/L. The maximum percentage removal of Cr(VI) in the tannery indust...
