Reverse osmosis (RO) membranes, as a core technology in water treatment, vary significantly in types and performance, directly influencing their effectiveness and applications. Based on material, structure, and purpose, RO membranes can be categorized as follows: 1. Classification by Material 1. Cellulose Acetate Membrane (CA Membrane) – Features: Unique chlorine resistance with a desalination […]
The efficient operation of Reverse osmosis equipment systems relies on the precise synergy of pretreatment, high-pressure pumps, and membrane modules. This article explores the core components and their collaborative mechanisms, integrating engineering practices and technological innovations. I. Pretreatment System: The “Lifeline” for Membrane ProtectionPretreatment serves as the first defense line, directly impacting membrane lifespan and […]
As industrial water demand shifts toward high-purity and low-energy consumption, the competition and integration among reverse osmosis (RO), ion exchange (IX), and electrodeionization (EDI) have become pivotal in water treatment. This article analyzes their substitutive advantages from technical principles, operational costs, environmental compatibility, and application scenarios. I. Technical Principles and Performance Comparison 1. […]
semipermeable membranes. The core principle involves applying high pressure (2-8 MPa) to raw water, forcing water molecules through a membrane with a pore size of 0.0001 microns, while dissolved salts (e.g., heavy metal ions), organic matter, bacteria, and viruses are rejected due to size or charge differencesKey steps include: Osmotic Pressure Overcome: When applied pressure […]
Industrial reverse osmosis (RO) equipment has become a cornerstone of modern water treatment, driven by its high-precision separation and modular design. This article explores breakthrough applications in electronics, pharmaceuticals, chemicals, power generation, and seawater desalination. I. Electronics Industry: Precision in Ultrapure Water Semiconductor manufacturing demands ultrapure water with 18 MΩ·cm resistivity. RO systems […]
Reverse osmosis (RO) equipment separates water from impurities through pressure-driven semipermeable membranes. The core principle involves applying high pressure (2-8 MPa) to raw water, forcing water molecules through a membrane with a pore size of 0.0001 microns, while dissolved salts (e.g., heavy metal ions), organic matter, bacteria, and viruses are rejected due to size or […]
1. Contaminant Removal Capability of RO Systems Heavy MetalsRO systems effectively remove heavy metal ions (e.g., lead, mercury, cadmium, arsenic) with a removal rate exceeding 99% due to their semi-permeable membrane with a pore size of 0.0001 microns. For example, in electroplating wastewater treatment, RO combined with nanofiltration achieves 95.89% recovery of nickel ions and reduces copper (Cu²⁺) […]
