Ammonia removal from aquaculture wastewater by high flux and high rejection polysulfone/cellulose acetate blend membrane

Removal of High Concentrations of Sulfate from Wastewater: Evaluating Different Methods and Proposing the Best Option

Background: Industrial wastewaters containing high amounts of compounds such as sulfate can cause serious risks to human health and environment. Therefore, proposing practical solutions with the lowest cost and the highest efficiency for pollutants removal is of special importance. The purpose of this study is to find a suitable method for treatment wastewater containing very high amounts of...

Removal of total ammonia nitrogen (TAN), nitrate and total organic carbon (TOC) from aquaculture wastewater using electrochemical technology: A review

Removal of High-Strength of Ammonium and Phenol from Coking Wastewater by Alcaligenes Faecalis No.4

Alcaligenes faecalis No.4, which is capable of heterotrophic nitrification and aerobic denitrification was used to treat coking wastewater (CW) to remove high-strength of ammonium and phenol. First, the phenol-degrading ability of No.4 was verified and a synthetic medium containing lactate and phenol as carbon sources was subsequently applied to the No.4 culture. Both carbon materials were enti...

Separation Efficiency of Epoxified-Polyethersulfone Blend Membrane for Chromium Removal

A microporous bisphenol A diglycidyl ether (DGEBA) epoxified-polyethersulfone (PES) blend membrane (EPES membrane) was prepared through dry-wet phase inversion. This study attempts to correlate the changes in membrane physical and chemical properties when the EPES membranes were exposed to different durations of dry-phase inversion, towards the separation efficiency of carcinogen chromium (VI)....

Removal of high-molecular-weight solutes during high-efficiency and high-flux haemodialysis.

BACKGROUND Although urea clearance is often increased during high-efficiency and high-flux haemodialysis to compensate for short treatment times, the impact of these treatment modalities on the removal of larger uraemic toxins has not been thoroughly investigated. METHODS We compared solute removal rates for five haemodialysis treatment strategies in vitro using neutral dextrans (molecular ra...
