There are various methods for feeding chemicals into the water supply system, such as solution form, slurry form, and solid dry form. Several chemicals are used in water production and wastewater treatment systems, each with its specific filling procedure. The result of chemicals usage by the most efficient, careful monitoring is the main mandatory. The control systems can be categorized as follows
Manual operation requires an operator to turn on and off each chemical filling system. It is suitable for small systems. The efficiency depends on an operators skill.
It is a combined method between the automatic system and human control. Therefore, the cost is saved from developing a full-control system.
Everything will be pre-programmed to be automatic. As a result, the maximum accuracy and little time loss for humans.
