Reverse Osmosis System
Reverse Osmosis (RO) is one of the most effective and widely used membrane-based water treatment technologies. It operates on the principle of pressure-driven filtration to remove dissolved salts, contaminants, and impurities, producing high-purity water for industrial, municipal, and commercial applications. At RTW UK, we provide advanced RO systems designed for efficiency, reliability, and sustainable water management.
How Reverse Osmosis Works
RO uses a semi-permeable membrane to separate impurities from water. When high pressure is applied to the feedwater, it forces the water molecules through the membrane while rejecting dissolved salts, ions, and other contaminants, resulting in purified water.
Process Steps
Pre-Treatment
Feedwater is treated to remove suspended solids and larger impurities, protecting the RO membranes from fouling and scaling.
Pressurization
The feedwater is pressurized to overcome the natural osmotic pressure and drive the water through the RO membrane.
Separation
Pure water (permeate) passes through the membrane, while impurities (concentrate or brine) are retained and discharged.
Post-Treatment
The permeate can undergo further treatment or conditioning based on its intended application.
Key Features and Benefits of RO Technology
High Removal Efficiency
Eliminates up to 99.8% of dissolved salts, heavy metals, microorganisms, and organic contaminants.
Versatile Applications
Suitable for desalination, water recycling, and ultrapure water production.
Energy Efficiency
Modern RO systems are designed with energy recovery devices to minimize operational costs.
Compact and Modular Design
RO systems are space-efficient and can be scaled to meet varying capacity needs.
Improved Water Reuse
Converts wastewater into high-quality water for industrial processes, reducing freshwater dependency.
Applications of RO Technology
Desalination
Converts seawater or brackish water into potable water for municipal or industrial use.
Industrial Process Water
Provides ultrapure water for applications such as electronics manufacturing, pharmaceuticals, and power generation.
Wastewater Recycling
Reclaims treated wastewater for reuse, aiding industries in achieving sustainability goals.
Boiler Feed Water
Supplies low-conductivity water to prevent scaling and corrosion in boiler systems.
Food and Beverage Industry
Ensures clean, contaminant-free water for production and processing.
Zero Liquid Discharge (ZLD)
Works as a critical step in ZLD systems to recover water and concentrate brine.
