A process for producing chlorine for treating flowing water supplies especially micro systems such as drip irrigation systems to control microorganisms present in these waters. It also relates to a chlorinator for practicing the process. The process comprises the steps of (a.) blending in a high pressure tank an excess of calcium hypochlorite and water to form a saturated top of the tank for feeding chlorinated water to a water supply containing microorganisms; (b.) sealing the tank; (c.) displacing a portion of the calcium hypochlorite sink by feeding water from the high pressure, variable speed pump to the dip tube. This forms additional saturated calcium hypochlorite solution; (d.) withdrawing saturated calcium hypochlorite solution through the feed line and adding the calcium hypochlorite to the flowing water supply; and, (e.) controlling the amount of calcium hypochlorite, e.g. chlorination rate fed to the flowing water supply by adjusting the delivery rate of the high pressure pump. The chlorinator for feeding saturated calcium hypochlorite solutions to flowing water systems to control microorganisms comprises (a.) a high pressure tank having a top, a bottom and a sealed removable cover near its top; (b.) a water delivery dip tube within the tank having an inlet and an outlet with the outlet being near the bottom of the tank; (c.) a high pressure, variable speed pump connected to the inlet of the dip tube; (d.) a feed line near the top of the tank for feeding the calcium hypochlorite solutions to the flowing water systems.
