Industrial Wastewater Treatment

Reverse osmosis (RO) and ultrafiltration (UF) are two popular membrane-based water purification technologies, each with distinct mechanisms, filtration capabilities, and applications. Understanding their differences is essential for selecting the right system for specific water treatment needs. Fundamental Differences in Technology Reverse Osmosis is a process that uses a semipermeable membrane to separate water molecules from dissolved inorganic substances, including salts, heavy metals, and other contaminants. It operates by applying high pressure to force water through a membrane with extremely fine pores, typically around 0.0001 microns. This process effectively removes nearly all dissolved solids and impurities, producing very pure water . Ultrafiltration, on the other hand, is a mechanical filtration process that uses hollow fibre membranes with larger pores, typically between 0.01 and 0.1 microns. It removes suspended solids, bacteria, viruses, and some larger organic molecules ...
