Description
Portable Hydrant Dechlorination System for Fire Hydrant Flushing & Pressurized Water Discharge
Product Overview
The Hydra-Max® Dechlorination System efficiently removes chlorine and chloramines from pressurized water flows without electro-mechanical components. This portable unit attaches directly to hydrants, handling flow rates between 150 and 900 GPM. It provides reliable neutralization for water treatment applications, ensuring compliance with federal, state, and local regulations.
Why Chlorine Neutralization During Flushing Matters
Discharging chlorinated water directly into storm drains or natural bodies of water can harm aquatic life and violate environmental regulations. Dechlorination minimizes the impact of toxic disinfection byproducts found in municipal water supplies.
Using a dedicated fire hydrant flushing dechlorination tool ensures that free and combined chlorine residuals are neutralized before the water enters the environment. This process meets strict discharge limitations while maintaining operational efficiency.
How the Hydra-Max® System Works
Flow-Rated Dosing Chamber
The system utilizes a compact dosing chamber that channels incoming water directly over the chemical tablets. This internal structure ensures consistent contact between the water and the dechlorination agent.
For compatible chlorine neutralizers, explore our full range of Water Treatment Tablets, including Enviro-C® and other dechlorination options designed for high-flow applications.
Tablet Dissolution Mechanism
Water flows through a removable stainless steel tablet cartridge containing multiple ¼" flow ports. These ports create turbulence that dissolves the tablets evenly, maximizing chemical efficiency and mixing.
Flow-Proportional Chemical Application
The unit delivers a consistent chemical dose in direct proportion to the velocity and volume of the incoming flow. This automatic dosing requires no manual adjustment during operation, ensuring precise treatment for varying flow rates.
Key Features & Performance Advantages
- Constructed from high-strength 6061-T6 aircraft-grade aluminum for durability.
- Corrosion-resistant materials withstand harsh field conditions and chemical exposure.
- Base unit includes 3" MNPT male threads on both inlet and outlet connections for hose, adapter, or gauge attachments.
- Optional accessory pack available for connection to standard fire hydrants.
- The removable stainless steel cartridge holds eight tablets for approximately 15 minutes of run time.
- Complete setup typically takes one operator just 1–3 minutes.
- Operates without electricity or mechanical parts, making it virtually maintenance-free.
Optional Accessory Pack
Accessory Pack Includes:
- 2.5" NST Inlet Swivel Coupling
- 2.5" NST Outlet Swivel Coupling with Flow-Directional Elbow
Designed for fast connection to standard fire hydrants while allowing operators to safely control discharge direction.
Applications & Field Use Scenarios
Common Applications:
- Fire hydrant flushing dechlorination
- New water main flushing
- Swimming pool backflushing
- Water reservoir drainage
- Emergency water discharge
- Construction site dewatering
- Pipeline maintenance
Use Cases:
- Municipal Utility Crews: Dechlorinating water during routine hydrant maintenance to meet environmental discharge permits.

Frequently Asked Questions
What tablets should I use with this system?
The Hydra-Max® system uses 2⅝ inch diameter dechlorination tablets such as Enviro-C (Vitamin C) or other compatible high-flow neutralization tablets designed for pressurized discharge applications.
Does the unit restrict water flow?
The system is designed to handle flows between 150 and 900 GPM with minimal restriction, making it suitable for standard hydrant flushing and pressurized discharge operations.
How often should the unit be cleaned?
The unit is virtually maintenance-free. After each use, rinse the stainless steel tablet cartridge and internal chamber with fresh water to remove chemical residue and maintain performance.
Can this system be used for drinking water treatment?
No. The Hydra-Max® Dechlorination System is designed for flushing and environmental discharge applications. It is not intended for treating water for direct human consumption.
Are tools required to change the tablets?
No tools are required. The threaded cap can be removed by hand to access and refill the tablet cartridge.
Is the swivel elbow included?
No. The standard Hydra-Max® base unit includes 3" MNPT male threads on both inlet and outlet connections.
An optional accessory pack is available that includes:
- 2.5" NST inlet swivel coupling
- 2.5" NST outlet swivel coupling with flow-directional elbow
This kit allows fast hydrant connection and controlled water discharge direction.
What is the maximum chlorine level the system can handle?
The Hydra-Max® system effectively treats pressurized water with chlorine levels up to 4 ppm within its rated flow range.
Can the unit be stored outdoors?
The 6061-T6 aluminum construction is corrosion-resistant and suitable for outdoor use. However, storing the unit clean and dry when not in operation will help extend its service life.
