One-Step Reverse Osmosis Based on Riverbank Filtration for Future Drinking Water Purification

The presence of newly emerging pollutants in the aquatic environment poses great challenges for drinking water treatment plants. Due to their low concentrations and unknown characteristics, cannot be efficiently removed by conventional processes, making technically, economically, environmentally friendly purification technologies increasingly important. This article introduces a one-step reverse osmosis (OSRO) concept consisting riverbank filtration (RBF) (RO) treatment. OSRO combines relatively low-cost natural pretreatment river with an advanced engineered system. RBF provides continuous source stable quality robust barrier contaminants. With pre-removal particles, organic matter, micro-pollutants (OMPs), microbes, becomes ideal system based on RO membranes, comparison direct intake surface water. removes almost 99.9% pathogens, viruses, OMPs, as well vast majority nutrients, thus meets requirements chlorine-free delivery high biostability. is cost effective compared standard series steps involving sprinkling filters, softening, activated carbon. Artificial bank (ABF), which functions artificial recharge combination sand system, proposed alternative supply from locally available resources. It also suggested that implemented wind power energy order more sustainable renewable. An OSRO-based decentralized reclaiming reuse. future focus systems provide through technically efficient, financially feasible, resource reusable, relevant means.
