Are you using the right mass flow controllers on your water treatment plant ammonia panel metering system?

In water treatment plants (WTP) ammoniators are critical in the chlorination disinfection process. The addition of ammonia is a common municipal water treatment method that ensures public water supplies are clean as possible for human consumption. However, handling ammonia gas and properly dispersing it throughout your process can be difficult.

The key to ammonia delivery in a large treatment plant that also maintains chlorine residual is to have a dry gas. If moisture or condensation is present in the ammonia system then corrosive sub-products are formed and will attack the meter components and seal materials. Making sure that the correct meter is installed, including specific material selection for ammonia service is paramount in preventing unplanned downtime.

Case Study: FLEXIM Use in a Polymer Delivery System at a WWTP


Utilizing FLEXIM flow equipment, a North Florida wastewater treatment plant was able to get reliable and accurate flow measurement of polymer, despite pulsating flow and very low velocity.
