SYSTEM APPLICATION

The Hydra-Max dechlorination system is designed to accept 2 ⅝" diameter Enviro-C or Bio-Max dechlorination tablets. The most common application for the Hydra-Max system is dechlorination of water flows during fire hydrant flushing. The system can also be utilized for flushing new water mains or backflushing swimming pools. An stainless steel tablet cartridge contains multiple ¼" flow ports to provide the proper amount of mixing and contact with tablets. This allows for complete neutralization of chlorine and chloramines while keeping chemical waste to a minimum. The Hydra-Max system provides a fast and simple set-up that saves operators time and money. There are no mechanical parts that require adjustment or components that can be easily damaged or broken. The compact, durable one piece construction offers operators a low cost, low maintenance system.

HOW THE HYDRA-MAX® SYSTEM WORKS

The Hydra-Max system is a flow rated device designed to safely apply chemicals in pressurized applications to remove residual chlorine. The Hydra-Max dechlorination system provides consistent and precise neutralization of chlorine to meet stringent water treatment requirements mandated by Federal, State and Local regulations.

The Hydra-Max system can be used for treating water flows discharging from fire hydrants, swimming pools and new water mains. When backflushing swimming pools or flushing new water mains, the Hydra-Max system is typically installed at the discharge point of the water flow and connected to a hose specified for these applications. The Hydra-Max system incorporates a 2 ½" NST coupling for easy and fast connection to any fire hydrant. The outlet incorporates 2 ½" NST male threads for use with hoses, pilot gauges or other test equipment. During operation, flow enters through the inlet hub and is channeled through the compact dosing chamber. As flow passes through the system, it dissolves the dechlorination tablets to provide complete removal of free and combined chlorine from the flow. It is recommended that you check the removable tablet cartridge after 15 minutes of operation. If needed, add tablets and continue flushing.

SYSTEM PERFORMANCE

The Hydra-Max dechlorination system has been designed for a flush rate of 150 to 900 GPM with chlorine levels up to 4 ppm. The complete set-up time is 1-3 minutes and typically requires only one operator. The Hydra-Max system provides a fast and easy way to dechlorinate pressurized flows in the most cost effective and efficient manner when utilizing Norweco’s Enviro-C or Bio-Max dechlorination tablets.
