Two methods of dosing solid hypochlorite (calcium hypochlorite) are:

Method 1: Tablet erosion feeder (or tablet chlorinator)
Hypochlorite tablets are loaded into a chlorinator chamber. Water flows through the chamber at a controlled rate, eroding and dissolving the tablets to form a chlorine solution. The dosing rate is adjusted by changing the water flow rate or tablet exposure. This method is simple, requires no electricity, and provides consistent dosing for small-scale applications like swimming pools or small water supplies.

Method 2: Powder feeder with solution preparation
Powdered calcium hypochlorite is fed using a dry chemical feeder (volumetric or gravimetric type, such as screw or vibratory feeder) into a mixing tank. It is dissolved in water to form a stock solution, which is then pumped into the main flow using a metering pump. The dosing rate is controlled by the feeder speed and pump stroke. This method is suitable for large-scale water treatment plants requiring precise and high-capacity dosing.
