USABlueBook Aluminum Dechlorination Diffusers
USABlueBook Aluminum Dechlorination Diffusers
• Convenient, easy-to-use tablet feed
• Safely neutralize chlorine/chloramines while flushing hydrants
Our dechlorination diffuser is for use with chemically treated (10 ppm or less chlorine/chloramines) potable water. It attaches directly to 2-1/2" NST hydrant threads to handle flows from 200 to 1250 gpm at pressures up to 200 psi. Diffuser features sturdy aluminum construction and weighs only 17 lbs.
The diffuser holds nine sodium sulfite tablets or ascorbic acid/vitamin C tablets. During flushing, spot check the tablet consumption approximately every 10,000 gallons of flow. A selection of tablets is listed below.
Customize diffuser with optional accessories
Add the tablet extension tube to load as many as 20 additional tablets to the diffuser feed. The tube features clear Lexan® construction, so you can see the level of the tablets and refill as needed.
We recommend the tablet screen when using ascorbic acid dechlorination tablets. The screen adjusts tablet consumption rate to the proper amount for 0 to 4 ppm chlorine concentration. Add an optional pitot tube assembly with gauge to convert this diffuser into a Dechlorination Diffuser/Flow Tester. It attaches easily with two mounting screws, and features a quick-disconnect connection for the gauge.
Use two low-flow inserts in situations where the flow is less than 200 gpm. These easy-to-install inserts redirect flow through the tablet feed area to ensure adequate exposure to the tablets.
For additional control over discharge, you can connect the diffuser to the hydrant via fire hose or with the steel hitch bracket holder, which lets you direct flow. For higher flow rates, use the hydrant wye to attach two diffusers at once to increase the flow capacity to approximately 2500 gpm. All items are sold separately below.
Note: Pitot tube assembly and gauge are sold separately.

USABlueBook Universal Liquid Chlorinator/Dechlorinators
USABlueBook Universal Liquid Chlorinator/Dechlorinators
• Cost-effective, time-saving device
• Attach directly to a fire hydrant or flushing diffuser
Use this handy multitasking device for liquid chlorinating/dechlorinating, and also as a flow testing diffuser when used with a Hydro-Hitch™ Water Diffuser. Connect it directly to a 2-1/2" NST fire hydrant port or in-line to a flushing diffuser.
Dechlorination
When using as a dechlorinator, it’s easy to adjust the amount of liquid dechlor—simply turn the thumb knob on the acrylic flow meter up or down while observing the scale. Suction flow rates of liquid dechlor range between 0.05 and 0.5 gpm. Within this range you can easily neutralize up to 50 ppm of chlorine. This device comes with two 2-1/2" glycerin-filled gauges with quick disconnects. The gauges monitor inlet and discharge pressures to ensure optimal Venturi performance.
Save time and money in the field by dechlorinating and flow testing your hydrants at the same time. Simply connect this universal liquid device to the Hydro-Hitch Water Diffuser (stock # 63285) and you can perform both tasks at once.
Chlorination
You can also use this device to inject chlorine into water lines. For a hydrant connection, use a swivel adapter (sold separately below) to connect the male outlet end of the device to the 2-1/2" hydrant port.
