Water Filtration

Filtration represents a broad category of treatment systems used to remove particles, taste, odor, some organics and minerals, and some bacteria from the water. Filtration systems fall into several categories:

• Mechanical or Sedimentation Filtration
• Oxidation Filtration
• Neutralizing Filtration
• Reverse Osmosis or Membrane Filtration

In many cases, these filtration systems are an integral component of other water treatment systems. To remain effective, all filtration systems must be regularly inspected and maintained.

Mechanical or sedimentation filters simply retain debris as water passes through the filter unit. Mechanical filters are most effective for removing particles such as sand, silt, ferric iron, algae and some bacteria. Their effectiveness will depend on the particle size and the exit clearance of the filter.
