The increasing demand for drinking water and its stricter quality requirements have resulted in an exponentially expanding industry of membrane filtration processes. Currently, reverse osmosis (RO) is the most common method of desalination, able to produce water that is virtually free of pollutants and pathogenic micro-organisms. Biofouling of these devices however is a significant limitation. Here we present a 3D simulation of RO membrane biofouling based on a lattice Boltzmann (LB) platform that we subsequently favorably compare with experimental data. This data consists of temporally (and spatially) resolved velocity measurements acquired for a RO membrane using magnetic resonance techniques. The effect of biofilm cohesive strength on system pressure drop is then explored; weaker biomass is observed to have a reduced impact on pressure drop (per unit biomass accumulated).

The consideration of scarcity and overexploitation of freshwater at the organizational level increased interest in the water footprint. The water footprint measures freshwater use for activities, taking into account water consumption and pollution contamination by classifying consumed water into groundwater and surface water (blue water), rainwater (green water), and polluted water (grey water). This study aims to identify a comprehensive water footprint inventory analysis for a denim washing organization and assess the grey water footprint (GWF) based on the effluent concentration of pollution indicators (chemical oxygen demand (COD), suspended solids (SS), ammonium nitrogen (NH4-N), and phenol) measured monthly in 2021.

Improving crop salinity management requires enhanced understanding of salinity responses of leaf and fine-root traits governing resource acquisition, ideally in relation to ion accumulation at intra- or inter-specific levels. We hypothesized that these responses are coupled towards integrated resource conservation for plants under prolonged salt treatment. We tested the hypothesis with a glasshouse experiment on saplings of six contrasting hybrids, subjected to either control or salt treatment (reverse osmosis water versus 3.

This article reviews the role of membrane systems in treating palm oil mill effluent (POME), a waste generated by the palm industry. The review focuses on various membrane systems such as microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO), highlighting their effectiveness in removing pollutants and recovering water. Special attention is given to hybrid systems integrating membrane bioreactors (MBRs) and other advanced processes to enhance fouling control, improve water quality, and promote sustainability.

The high salt content and color are regarded as a major challenge to the reuse of industrial wastewater. In the present study, the application of cellulose acetate reverse osmosis (RO) membrane in combination with microfiltration (MF), ultrafiltration (UF), or nanofiltration (NF) process was investigated in the purification of biological and Fenton treated pulp and paper wastewater. In the first step, the effect of pH and inlet pressures on the membrane fouling was investigated.
