The treatment of the yeast industry wastewater was investigated by nanofiltration (NF) membrane process on a pilot scale. Two wastewaters were used as feed: (i) dilute wastewater with COD 2000 mg/L and (ii) concentrate wastewater with COD 8000 mg/L. The permeate flux, COD retention, color and electrical conductivity (EC) removal were evaluated in relation to trans-membrane pressure and long-ter...

The discovery that natural and synthetic chemicals, in the form of excreted hormones and pharmaceuticals, as well as a vast array of compounds with domestic and industrial applications, can enter the environment via wastewater treatment plants and cause a wide variety of environmental and health problems even at very low concentrations, suggests the need for improvement of water recycling. Thre...

At water resource recovery facilities, nutrient removal is often required and energy recovery is an ever-increasing goal. Pyrolysis may be a sustainable process for handling wastewater biosolids because energy can be recovered in the py-gas and py-oil. Additionally, the biochar produced has value as a soil conditioner. The objective of this work was to determine if biochar could be used to adso...

application of granular activated carbon (gac) in adsorption process has been studied for the advanced treatment of municipal and industrial wastewater. because of entering poisonous compounds such as furfural, phenol and sulfides into the oily wastewater of tehran refinery, biological aeration basins of wastewater treatment unit may not have the desired performance of cod reduction. in this st...

Objective: The aim of this study was to investigate the effect of pre-treatment with curcumin on metabolic changes induced by two different pathophysiological mechanisms in rats (fructose diet and streptozotocin (STZ)-induced diabetes mellitus). Materials and Methods: Five groups with 10 rats per group were investigated: control group (healthy rats), fructose diet groups without any pre-treatme...

Reverse osmosis (RO) desalination is considered a viable alternative to reduce water scarcity; however, its energy consumption high. Photovoltaic (PV) in processes has gained popularity recent years. The temperature identified as variable that directly affects the behavior of different parameters RO process and production PV panels. objective this study was evaluate effect on polarization facto...

Poultry slaughterhouses produce a large amount of wastewater, which is usually treated by conventional methods. The traditional techniques face some challenges, especially the incapability recovering valuable nutrients and reusing water. Therefore, membrane technology has been widely adopted researchers due to its enormous advantages over Pressure-driven membranes, such as microfiltration (MF),...

Abstract Chlorine disinfection has been reported to be ineffective in controlling RO membrane biofouling some projects. Feed water temperature is a crucial factor the formation of biofouling. It positive impact on wide application process ascertain whether chlorine can alleviate at low temperatures. In this study, effects chlorination feed (10 °C) were investigated by lab-scale apparatus. The f...
