  1. Use the conventional method

    The conventional turbidity treatment method adds coagulant chemicals to the water source. The filtration system then flash mixes the chemicals so they coagulate, and sedimentation removes the floating materials to rid the water of turbidity. The direct approach is similar to the conventional route; however, it doesn't utilize the sedimentation approach.

  2. Apply packaged or bag filtration systems

    Packaged filtration systems are applied to treat small community water supplies. These units are mounted on frames for rudimentary pipe and service measures. The bag filtration method uses disposable bag filters within a steel vessel. The vessels are made of steel for strength, corrosion resistance and disinfection purposes.

  3. Use sand

    In addition to these measures, you can utilize clean sand to remove turbidity. Pour the muddy water from a transport container through a container holding sand and gravel with at spigot at the bottom. The sand effectively catches the bacteria, allowing clean water to flow to the empty container placed underneath.
