Activated carbon systems are frequently combined with other filtration technologies.

Reverse Osmosis Systems

Reverse osmosis systems use membrane filtration to remove dissolved salts, minerals, and microscopic contaminants from water. High-pressure pumps force water through semi-permeable membranes that separate impurities.

Reverse osmosis is commonly used in:

• Desalination facilities
• Pharmaceutical manufacturing
• Boiler water treatment
• Electronics production

These systems are widely used where high-purity water is required.

Ultrafiltration and Membrane Systems

Membrane filtration technologies use fine membranes to remove bacteria, suspended solids, and organic matter.

Common membrane categories include:

• Microfiltration
• Ultrafiltration
• Nanofiltration
• Reverse osmosis membranes

These systems are increasingly used in industrial wastewater treatment and water recycling operations.

Ultraviolet Water Treatment

Ultraviolet treatment systems use UV light to deactivate microorganisms in water. This method is commonly used as a disinfection stage without adding chemical disinfectants.

Applications include:

• Drinking water systems
• Wastewater treatment plants
• Food processing facilities
• Laboratory water systems

UV systems are often combined with filtration technologies for improved treatment performance.
