Typical water constituents are classified under

• Coarse particles like leaves, twigs etc.
• sand particles
• suspended solids, which mostly are settleable
• colloidal particles, which cause turbidity
• microorganisms like bacteria, viruses, algae etc.
• dissolved organic matters
• dissolved minerals
• dissolved gases like O2, CO2 etc.
• specific parameters like pH, total hardness, alkalinity, silica, iron/manganese etc

TEW Water Processing

 involves the removal of water constituents to achieve the degree of purity required for

• Potable and drinking water
• Industrial water
• Irrigation

The duty of a municipal water treatment plant is to provide potable water which is chemically and bacteriologically safe for human consumption

For a conventional TEW water treatment process,there are some alternatives and optional modifications like

• multi-stage mixing / flocculation System presedimentation unit
• direct filtration process etc
