What Is Water Treatment?

We do not lack water, what we lack is pure water.

The way of water treatment includes physical and chemical treatment. Through a series of operations such as filtration, sedimentation and purification, water purification is achieved. Through effective water treatment methods, you can improve the utilization of water resources and environmental protection.

The valve is an indispensable part of water treatment. They help to transport water and improve productivity.

As a manufacturer of automated valves, COVNA understands the needs of the water treatment industry. In this article, we will introduce you to the valves available for the water treatment industry.

Valve Applications For Wastewater Treatment System

  • Flow Control

    Valves allow operators to regulate the flow rate, redirect the flow, or shut off the flow altogether

  • Process Control

    They are used to regulate the addition of chemicals, adjust the pH levels, control aeration or mixing, and manage the movement of solids or sludge

  • Safety and Reliability

    They can isolate sections of the system during maintenance or repairs, prevent the release of hazardous substances, and protect equipment from damage

  • Backflow Prevention

    Valves, such as check valves or backflow preventers, are installed to prevent backflow and ensure the integrity of the treatment process

  • Maintenance and Repair

    Valves allow for the isolation of specific sections of the wastewater treatment system, making maintenance and repair activities more manageable
