Direct Capillary Nanofiltration (Direct CNF) is a new technique used for surface water and wastewater treatment in one step without pre-treatment. The CNF membrane module combines the favourable cleaning properties of capillary ultrafiltration membranes with the favourable separation properties of nanofiltration membranes in terms of removal of DOC, colour, bacteria, viruses and pesticides. Dir...

Phytoremediation offers a cost-effective, non-intrusive, and safe alternative to conventional cleanup techniques. In this study, we used ornamental hydrophytes plants as constructed wetlands to treat urban or rural domestic wastewater. Most ornamental hydrophytes adapted to the wastewater well, and were fairly efficient in scavenging BOD5 (biological oxygen demand 5 d), COD (chemical oxygen dem...

The objective of this paper is to critically review the significance of MBR technology for wastewater treatment derived Biodiesel plant with Alkali-Catalyzed Trans-esterification process. The whole study was carried out into two stages. In the first stage, pretreatment was studied with H2SO4 at the different pH range of 2.4 to 9 along with the removal efficiencies of BOD, COD and Oil & Greases....

Abstract In recent days, the waste productions from industries are increased and direct discharge of wastes causes various pollution to environment. Wastewater treatment in textile dye industry mainly involves highly colored wastewater containing variety dyes different concentrations. The dyeing using types pigments concentration during their several production steps. These a which contains org...

A ceramic membrane modified with corncob activated carbon (CMCC) has been successfully prepared and used to reduce the concentration of remazol red in batik wastewater. This research aims study effect (CC) on porosity its ability dye The variation % CC mass clay was 0%, 5%, 10%, 15%, 20%, 25%. Characterization includes ash content characterization CMCC test, morphological analysis, elemental di...

Sustainable mining and mineral processing is of paramount importance for producing metals needed our society development. Membrane processes are able to contribute the comprehensive extraction from mined ores, while at same time decrease amounts used water reagents ensure discharge environment wastewater meeting legislation requirements. Membranebased technologies still underused in obtaining a...

BACKGROUND Purified terephthalic acid (PTA) wastewater from a petrochemical complex was utilized as a fuel in the anode of a microbial fuel cell (MFC). Effects of two important parameters including different dilutions of the PTA wastewater and pH on the performance of the MFC were investigated. METHODS The MFC used was a membrane-less single chamber consisted of a stainless steel mesh as anod...

Membrane based treatment processes are very effective in removing salt from wastewater, but are hindered by calcium scale deposit formation. This study investigates the feasibility of removing calcium from treated sewage wastewater using accelerated seeded precipitation. The rate of calcium removal was measured during bench scale batch mode seeded precipitation experiments at pH 9.5 using vario...
