Pretreatment
- If the hardness exceeds 10 gr/gal, softener is recommended.
- If the silica content is high, it is necessary to inject an antiscalant. It does not affect the product water because it does not pass through the osmosis membrane.
- If the iron or manganese content is high, a suitable catalyst (Katalox Light, Green sand plus, or Z-OX) is required.
- If the water contains chlorine, it must be dechlorinated with activated carbon.

Industrial reverse osmosis is an assembled package ready to be installed at the place of use.
The best option for demineralization or water purification is Industrial Reverse Osmosis.
- Principle of operation: Reverse osmosis (RO) uses applied pressure to force water through a semi-permeable membrane, which retains contaminants such as salts, minerals, heavy metals, bacteria and viruses, allowing only purified water to pass through.
- Main components:
- High pressure pump: Provides the necessary force for the water to cross the membrane.
- Reverse osmosis membranes: The heart of the system, designed to allow water to pass through and reject contaminants.
- Prefilters and postfilters: They remove large particles and condition the water before and after the osmosis process.
- Controls and sensors: Monitor and adjust key parameters such as pressure, flow and water quality.
- Washing system (CIP): Allows the membranes to be cleaned in situ to maintain their efficiency.
- Applications:
- Drinking water production: Removal of salts and contaminants from water from natural sources to make it safe for human consumption.
- Wastewater treatment: Purification of industrial and municipal water, allowing its reuse or safe discharge into the environment.
- Industrial processes: Provision of high purity water for the pharmaceutical, food, and semiconductor manufacturing industries, among others.
- Benefits:
- High efficiency: Removes up to 99% of the contaminants present in the water.
- Flexibility: Adaptable to various inlet water qualities and outlet requirements.
- Sustainability: Reduces dependence on fresh water sources and minimizes environmental impact by allowing water reuse.
- Operational considerations:
- Maintenance: Requires regular monitoring and maintenance of membranes and components.
- Concentrate management: The management of rejects or concentrates generated, which contain high concentrations of contaminants.
- Energy consumption: The operation of high-pressure pumps involves significant energy consumption, although there are emerging technologies that seek to improve energy efficiency.
Industrial reverse osmosis is a key technological solution to meet the challenges of clean water supply and wastewater management in the context of a world in constant urbanization and industrialization.
