Common Pollutants Removed

• Suspended Solids: These particles, such as silt, clay, and sand, can clog pipes and equipment, causing operational issues and making water appear cloudy.
• Dissolved Solids: Minerals like calcium, magnesium, and iron can lead to scale buildup in pipes and equipment, and may give water an unpleasant taste.
• Organic Matter: Bacteria, viruses, and other microorganisms can cause waterborne illnesses and contribute to unpleasant odors in water.
• Chemicals: Various industrial, agricultural, and household chemicals can be hazardous to both human health and the environment.

Common Methods

Several methods are used to remove pollutants from water during the process, each tailored to specific contaminants:

• Sedimentation: This process relies on gravity to settle suspended solids at the bottom of a tank.
• Filtration: A filter is used to physically remove both suspended and dissolved solids from the water.
• Coagulation and Flocculation: Chemicals are added to cause suspended solids to clump together, making them easier to remove through filtration.
• Aeration: Air is introduced into the water to remove dissolved gases, such as hydrogen sulfide.
• Oxidation: Chemicals are used to oxidize organic matter, reducing its harmful effects.

The appropriate method or combination of methods will depend on the pollutants present in the water and its intended application.

Advanced Water Technologies For Pretreatment

In addition to traditional methods, several advanced technologies are available for more complex needs:

• Reverse Osmosis (RO): This membrane-based technology removes dissolved solids by forcing water through a semipermeable membrane.
• Nanofiltration (NF): A membrane process that removes smaller dissolved solids than reverse osmosis, ideal for specific filtration needs.
• Ion Exchange: This process exchanges ions in the water using resins to remove certain contaminants.
• Electrodeionization (EDI): This technology uses DC power, ion exchange membranes, and resin to deionize water, ensuring ultra-pure water quality.

Choosing the right technology will depend on the specific pollutants and the desired water quality. Each of these technologies plays a critical role in ensuring water safety and protecting equipment from damage.

Water pretreatment is a key part of industrial and commercial water treatment systems. By removing pollutants before water is used, pretreatment protects equipment, ensures water safety, and helps prevent waterborne illnesses. ChemREADY offers a range of technologies to meet the unique water treatment needs of any facility, ensuring water quality and system reliability.
