Test with the mobile unit on a municipal wastewater treatment plant
Tests carried out Sludge in recirculation on the oxidation tank, after dynamic thickener and in recirculation on the mesophilic and thermophilic digester. Goal Maximize the yield of the oxidation and digestion processes, increase dehydration and reduce the volume of sludge to be disposed of. Results COD 30 times greater on the cavitated sample taken on the water line and 4 times greater on the ...

Pulp and Paper Article: Improving Wastewater Treatment Processing with Online Monitoring
Wastewater treatment professionals in the Pulp and Paper industry face difficult challenges. Many of the manufacturing processes are heavily reliant on water, resulting in large volumes of wastewater that can contain complex mixtures of organic pollutants, solids, and other chemicals. Wastewater treatment is often necessary to meet environmental effluent discharge permit limits or comply with ...

Removal of ecotoxicity and COD from tank truck cleaning wastewater
Tank truck cleaning (TTC) activities generate highly complex wastewater. In a previous study, we found that a significant ecotoxic effect was still present in biologically treated TTC wastewater. The aim of the present study was therefore to investigate the removal of acute toxicity from TTC wastewater by a sequence of technologies routinely applied for industrial wastewater. Acute toxicity was ...

Eco-friendly process combining physical–chemical and biological technics for the fermented dairy products waste pretreatment and reuse
Residual fermented dairy products resulting from process defects or from expired shelf life products are considered as waste. Thus, dairies wastewater treatment plants (WWTP) suffer high input effluents polluting load. In this study, fermented residuals separation from the plant wastewater is proposed. In the aim to meet the municipal WWTP input limits, a pretreatment combining ...

Study about the treatability of an industrial stream by means advanced BM Respirometry - Case Study
When it is needed to know whether a particular type of industrial stream can be treated biologically, either because it is expected to be incorporated into the global influent of the treatment process or because has to be individually eliminated in a new biological treatment, it is necessary to know its biodegradable character, degree of toxicity or possible inhibition that could cause in the ...

Efficient Waste Water Treatment
Clean drinking water is an essential need of mankind. Often surface water like rivers or lakes is used as drinking water source. To prevent these resources from pollution the effective treatment of waste water is a must. For example in China 75% of discharged waste water is coming from pulp and paper, textile and dyeing industries. To run a waste water treatment plant in the most efficient way ...

Oxidative destruction of foaming agent, COD and TOC in wastewater using advanced oxidation technologies
In recent years, improvement in ozone based advanced oxidation process design and efficiency resulted in lower capital and operating costs. An investigation into alternatives for hard COD, TOC and foaming agent oxidative destruction which is economically attractive and do not generate sludge, lead to the evaluation of our ozone based advanced oxidation processes (AOP). The results of this pilot ...
