Wastewater

The aim of this paper is to propose an efficient and low-cost treatment of chemical mechanical polishing wastewater process based on electrocoagulation with iron bipolar electrodes. The performance of a pilot scale electrochemical reactor equipped with iron bipolar electrodes and an anode active are

One of the methods of achieving high selectivity or high flux for specific compounds is the modification of membrane such as filling, grafting or coating. The most common is adding fillers, especially high aspect ratio fillers. It improves physical properties such as increased stiffness or reduced c

Water scarcity is becoming a serious problem in the Mediterranean countries. To minimize negative effects, wastewater reclamation can be one of the possible solutions. Reverse osmosis (RO) is the process that ensures the highest water quality. Thus, the required quality goal can be reached adjusting

In this study, Remazol Black B dyestuff removal from wastewater by ion exchange was investigated with in a batch system and 23 full factorial design was applied. Anion exchanger resin was prepared from agricultural residue (straw) after reaction with epichlorohydrin and dimethylamine in the presence

The water consumption increases at high speed under the effect of the demographic growth and the agricultural and industrial development. This water consumption involves a significant and increasing quantity of wastewater. These untreated rejections generally are poured in receiving environment (lak

A new method of membrane sequencing batch reactor (MSBR) process in abattoir wastewater treatment is given. With nitrification and denitrification bacterium, it is effective to remove nitrogen. At the same time, the whole system can be autocontrolled and do not add any drugs or bacteriums again afte

The continuing development of higher performance selective membranes of reverse osmosis, RO, and nanofiltration, NF, enables the elaboration of separation processes and wastewater treatment methods based on simple or hybrid membrane processes. The present work reports on the continuation of a long t

Fouling of UF membranes by humic acid particles was studied. Six types of UF membranes namely PAN 20 kDa (Rhone-Poulenc), PAN 100 kDa (Osmonics), PES 150 kDa (Microdyn-Nadir) and PS 10, 50 and 100 kDa (Permionics) were tested. Analysis of the results showed that the resistance due to the adsorption

Different category-wastewater samples were collected from the inlets of biological treatment plants (installed in hospitals, industries and municipality) and from the body of polluted natural surface water (PNSW) systems (lakes, rivers). UV absorption spectral data of each wastewater system or their

Up to 1990 a new phenomena concerning environment has taken place in our country. Many industrial enterprises were totally or partially closed. But leather tanning and processing factories which were represented by 5 enterprises located from the north to the south in Shkodra, Tirana, Vlora, Korça, G
