Monochloramine water disinfection system and method

This invention describes a system that disinfects water by automatically creating monochloramine, a germ-killing chemical. It works by injecting a chlorine source and an ammonium source into a water stream, precisely controlling how much of each chemical is added based on the water flow rate. The system also monitors the water to ensure the right amount of disinfectant is present without over-dosing.

Why it matters: The short two-year gap since filing means no significant technological shifts have occurred to simplify this system. The primary challenge remains integrating reliable, low-cost sensors and precise chemical dosing for widespread adoption.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedChemical dosing pumps, multiple sensors, control software.
