Clean water and its requirement are one of the emerging needs in recent days. Water pollution creates more amount of toxic nature to the clean water and it increases the accumulation of poisonous contaminants in the water sources. Heavy metal ions are the type of toxic pollutant released from...

Hazardous metal chromium is used extensively in many different industrial processes and is commonly found in industrial effluents. Hazardous pollutants such inorganic anions, metal ions, synthetic xenobiotics, and others have contaminated ground and surface waters in India and other parts of the...

Azo dye is a synthetic aromatic dye which are direct dye frequently used in textile industry to colour fibres. It also contributes to the damage of the environment. This study examines the adsorption biochar made from Annona reticulata to remove azo dye from textile wastewater. To improve the...

The photocatalytic process as an advanced oxidation process (AOP) has gained worldwide attention in the water and wastewater industry. The photocatalytic process can be used for water and wastewater disinfection. The aim of this study was to remove coliforms and faecal coliforms from real hospital...

People are prompted to complain about air pollution by offensive odours. They can produce psychological consequences, such as nausea, headaches, lack of appetite, breathing difficulties, and various adverse reactions in some circumstances. Among various industries, the dairy industry emits the most...

Batch adsorption studies of heavy metals were carried out using activated charcoal groundnut shell powder as an adsorbent material. The groundnut shell was collected and synthesized by chemical synthesis to convert it into charcoal form. The prepared adsorbent’s pore size & surface area was analyzed...

The constant development of technological processes aggravates the problem of pollution, due to a significant change in the composition of effluents, which makes necessary new (and/or improved) treatment methods and catalytic materials. In this sense, the use of natural clays in the synthesis of low...

With the increase in industrial and agricultural activities, huge amount of wastewater containing nitrogen is produced. Biological denitrification is currently the most widely used, sustainable and cost-effective process to remove nitrogen from wastewater. In biological denitrification, application...

The current research was aimed to investigate the performance of combined persulfate oxidation process and tannin via coagulation-flocculation processes as a post treatment of anaerobically treated palm oil mill effluent (AnT-POME). Different dosages of sodium persulfate (Na2S2O8, 238 g/mol) 0.1 (w...

Catechol is used as an antioxidant, fungicide, and polymerization inhibitors in a variety of industries such as petrochemical. Catechol must be removed from effluents before it enters to environment. This study aimed to investigate combined UV radiation and persulfate process in removal of catechol...

In this study, the aerobic and anaerobic biodegradability of the industrial wastewater from the vegetable tanning process were evaluated. Water from a food wastewater treatment system was used as seed inoculum for the aerobic process and mature granular methanogenic sludge from a brewery industrial...

Wastewater from textile industry is considered one of the major environmental challenges due to the large volume of highly colored, polluted and toxic effluent. This study investigated the treatability of real textile wastewater by pilot-scale anoxic-aerobic Membrane Bioreactor (MBR) system without...

Tannery industries provoke the conspicuous quantity of deleterious effluent which has to be treated prior to discharge into the environment. Pre-treatment of tannery wastewater with aluminium sulphate is well known over decades, but due to the corrosive nature of sulphate this pre-treated water...

The Membrane Bio-Reactor (MBR) technology offers a series of environmentally-friendly advantages, such as high quality effluent, pathogens removal capacity and avoided use of chemicals for disinfection, allowing it to be regarded as an environmentally friendly technology, when applied for wastewater...

The present study investigates the process optimization for treatment of potato processing industry wastewater by electrocoagulation. Performance of treatability was evaluated by achieved chemical oxygen demand (COD) removal efficiencies. Response Surface Methodology was applied to determine...

Presence of metals even at trace levels in natural waters pose sever health risks. Heavy metals are introduced to coastal and marine environments through a variety of sources and activities including sewage and industrial effluents where Black Sea is not different. However, metals behave differently...

The biosorption of Cr (III), Zn (II) and Ni (II) ions from aqueous solution by dead blue algal biomass (Cyanophyta) was investigated in single metal system and batch conditions. Experimental parameters included contact time (0-140 min), pH (2-8), sorbent dose (0.1-2.0 g), initial concentrations (10...

Increasing demand for water from agriculture, industrial and domestic sectors, resulted in stress on the water resources both from quantity and quality perspectives. Due to urbanization many of the dyeing units have shifted from urban to nearby rural areas. Here safe disposal of untreated effluent...

Slaughterhouse wastewaters are characterized by a high organic content, mainly composed of proteins and fats. Therefore, these wastewaters should be treated efficiently prior to discharge into receiving bodies to avoid severe environmental pollution. This work aimed to characterize slaughterhouse...

In this study, the photocatalytic degradation of two biologically treated textile finishing wastewater was investigated using powdered TiO 2 and ZnO catalysts with UV-A lamp irradiation. Photodegradation and photodecolorization of the samples real textile industrial wastewater is observed directly...
