Advanced wastewater treatment using membranes are popular environmental system processes since they allow reuse and recycling. However, fouling is a key limiting factor and so proprietary systems such as Avanti's RPU-185 Flexidisks membrane bioreactor (MBR) use novel rotating membranes to assist in ameliorating it. In earlier research, this rotating process was studied by creating a simulation ...

this document provides feasibility study of using treated domestic wastewater in concrete mixing. today, concrete is one of the most important construction materials. from first time that concert was used in construction materials, always the drinkable water used for concrete mixing water. domestic wastewater contains about 400 ppm of organic materials. after the treatment of wastewater, concen...

The purpose of this article is to review the current physical, chemical and hybrid technologies practices employed in removal pharmaceuticals from liquid effluents originating various resources including municipal waste, hospitals discharge with a focus on pharmaceutical manufacturing industry. Pharmaceutical pollutants are mostly persistent organic compounds that not easily removed by conventi...

It is assumed that microbial communities involved in the biological treatment of different wastewaters having a different chemical composition harbor different microbial populations which are specifically adapted to the environmental stresses encountered in these systems. Yet, little is known about the composition of these microbial communities. Therefore, the aim of this study was to assess th...

introduction: treatment of wastewater due to product and consumption of material cleaning with special physicochemical characteristics is difficult, and therefore can cause significant environmental problems such as eutrification, toxicity, algae bloom and etc.to stop these consequences, assessing the quality characteristics of this wastewaters is necessary. to investigate about the appropriate...

Hospital wastewater represents an infectious and toxic risk to human health the environment due its contents. Most hospitals in developing countries, including Benin, do not have a treatment plant. In this study, from two northern Benin was characterized then treated with Azadirachta indica leaves, Moringa oleifera Luffa cylindrica seeds by coagulation/flocculation process. The characteristics ...

this study assesses the effect of major trace metals levels in wastewater discharges and sedimentfrom twenty four permanent and five semi-permanent wastewater drain outlets into the kuwait coast. theeffect of trace metals levels released from untreated wastewater discharges to euchelus asper, gastropod was also determined. results showed high trace metal levels in e. asper tissues, followed by ...

Introduction: Given its effects, hospital waste is an environmental concern and a threat to health personnel, users of services neighboring populations. Our objective was assess the perception care stakeholders on effects related biomedical produced in Teaching Hospitals (CHU) Togo 2021. Methods: This cross-sectional study held from June 24 August 28, It targeted three university hospitals, 340...

Hospital wastewater has special importance since having pathogens, radioactive materials, pharmaceutical wastes and heavy metals. Removing them into environment without any treatment may cause serious problems for the public health. Membrane Biological Reactor is the combination of the activated sludge and membrane filters. This research has investigated the performance of the Nano-Filtration i...
