The efficiency of the Wastewater Treatment Plant (WWTP) strongly depends on the inlet flow and the component concentrations of the wastewater. The forecasting of WWTP load gives promising opportunities to accomplish relevant operational actions. A predictive control strategy has been implemented. Taking advantage of the recognized properties of universal approximation of neural networks (NN), a...

As a result of uncontrolled discharge of wastewaters containing high levels of phosphorus to the receiving bodies could create adverse effects on water quality. Therefore phosphorus should be eliminated prior to discharging into aquatic environment together with carbon and nitrogen to reduce eutrophication risk. Control of effluent phosphorus level by enhanced biological methods became a standa...

Abstract The study set the goal of improving efficiency various technological schemes purification plants enterprise through development an expert system based on fuzzy logic methods and formation practical recommendations for characteristics wastewater from operation plants.

The environmental loading of steroid hormones contained in dairy wastes may cause an adverse effect on aquatic species. To better assess the potential risks of hormone contamination resulting from land application of dairy wastes, various steroid hormones were determined in a typical dairy waste disposalsystem.Quantitativemethodsusinggaschromatography/ mass spectrometry (GC/MS) were developed t...

Coking wastewater from the process of coking, coal gas purification and the coking products refine, whose ingredients are complicated and inconstant, is hard to meet the standard of reclaimed water used for industrial water by secondary treatment. In view of this situation, the advanced treatment technique of coking wastewater was desired. The innovatory flocculation treatment was used to regen...

agricultural and specifically industrial activities have led to a substantial release of toxic heavy metals in the environment which can constitute a major hazard for ecosystem and human health. biosorption of heavy metals is one of the most effective technologies involved in the removal of toxic metals from contamination sites that has used in the last decade. population and microbial activity...

Membrane Distillation (MD) is a membrane-based operation able to give 100% theoretical ions rejection and to efficiently work with high concentrated brines. Both features make MD of interest for the purification of wastewater, the production of ultra-pure water and the concentration of brines produced in desalination. MD, also integrated with other membrane operations, can be a valuable way to ...

Nowadays, synthetic diamond has been studied for its application in wastewater treatment, electroanalysis, organic synthesis and sensor areas; however, its use in the water disinfection/purification is its most relevant application. The new electrochemistry applications of diamond electrodes open new perspectives for an easy, effective, and chemical free water treatment. This article highlights...

The meat industry is characterized by high water consumption. Since this wastewater is highly loaded, it should be thoroughly pre-treated prior to its discharge into receiving water. Our investigations revealed that a hybrid system of ultrafiltration and reverse osmosis is a promising purification method. Its application resulted in a 100% and 98.8% removal of phosphorus and nitrogen compounds,...
