CIS : Chemical Injection System
There are multiple approaches for injecting chemicals into water systems, including in solution form, slurry, or as dry solids. Each chemical used in water treatment and production processes requires a unique method for proper injection. To ensure optimal results, consistent and precise monitoring of chemical dosing is essential and must be strictly maintained.

The control methods for chemical injection systems can be divided into the following categories :
- Manual Control (Operator-Based System)
This method involves human operators manually starting and stopping the chemical dosing process. It is best suited for smaller-scale operations, where efficiency relies heavily on the operator’s experience and attention to detail.
- Semi-Automatic Control
This approach blends manual and automated elements, offering a cost-effective solution that reduces the need for a fully automated system while still improving consistency over purely manual methods. - Fully Automatic Control
In a fully automated system, all operations are controlled through pre-programmed settings. This enables high precision, minimizes human involvement, and significantly reduces the chance of error or delay.
