in this research, polyvinylchloride based composite heterogeneous cation exchange membranes were prepared by the solution casting technique. chitosan-co-iron nickel oxide nanoparticles were utilized as membrane surface modifier to improve the membranes electrochemical properties. the effect of additive nanoparticle concentration in the modifier solution on the properties of composite membranes ...

Membrane fouling has been regarded as one of the biggest challenges to widespread application of membrane bioreactor (MBR). This study focuses on minimizing the membrane fouling and improving the performance of submerged membrane bioreactor (SMBR) by porous sponge addition. The effects of sponge addition on sustainable flux and membrane fouling were investigated. Acclimatized sponge could signi...

The Tagouchi method was used for providing the instruction of ultra-filter dairy membrane cleaning. The goal function with using of four undimentionalized parameter, i.e., water and milk serum flux, percent of protein and dry mass of permeate, as quality indicator of cleaning of cleaned membrane, was defined. As a result, basic cleaning solution was found as follows: 0.8% NaOH, 1.0% EDTA, 1.0% ...

The industrialization in Lagos State has impacted the Ibeshe watershed, as a result, lower water quality is being experienced. Hence, novel way on potential use of waste to treat watershed by synthesizing graphene oxide and incorporating it into PET bottle membranes was studied. Polyethylene terephthalate (PET) embedded with 1wt%, 2wt%, 3wt% (GO) (M1, M2, M3), were prepared via non-solvent-indu...

BACKGROUND Dyslipidaemia, inflammation and oxidative stress are prominent risk factors that potentially cause vascular disease in haemodialysis patients. Dialysis modalities affect uraemic dyslipidaemia, possibly by modifying oxidative stress, but the effects of dialyser flux and membrane material on atherogenic remnant particles and oxidized low-density lipoproteins (LDL) are unknown. METHOD...

Separation of amoxicillin from pharmaceutical wastewater by nanofiltration (NF) membrane has been investigated in this study. For this purpose a membrane system including a polyamide spiral wound NF membrane was evaluated for the treatment of amoxicillin wastewater. The effects of operating conditions such as flow rate, pressure and concentration of amoxicillin and COD in the feed, on the effic...

Polyethylene terephthalate mesh (PET) enhanced cellulose acetate membranes were fabricated via a phase inversion process. The membrane fabrication parameters that may affect the membrane performance were systematically evaluated including the concentration and temperature of the casting polymer solution and the temperature and time of the evaporation, coagulation and annealing processes. The wa...

BACKGROUND Hyperhomocysteinaemia is a putative risk factor for atherothrombotic cardiovascular disease in the haemodialysis population. High-dose vitamin B therapy does not entirely normalize elevated plasma total homocysteine (tHcy) levels in haemodialysis patients. Alternative therapies to reduce tHcy further are therefore required. Modifications of the dialysis regimen may result in a better...

Ultrafiltration (UF) fouling has been attributed to concentration polarization, gel layer formation as well as outer and inner membrane pore clogging. It is believed that mass of humic materials either retained on membrane surface or associated with membrane inner pore surface is the primary cause for permeate flux decline and filtration resistance build-up in water supply industries. While bio...
