The complete solution for water hygiene and Legionella prevention: SANIKILL Monochloramine for drinking water.
In order to meet the high quality, safety and hygiene levels, it is important to keep high microbiological standards. Sanipur has numerous solutions for the disinfection with monochloramine for drinking water suppliers and municipalities.
Do you know that approximately 50% of the people in the United States receive water with monochloramine from the public water utility?
What is Monochloramine?
Monochloramine is a chlorine-based disinfectant widely used in municipal water systems due to its unique chemical properties. It is produced in situ through the reaction of chlorine and ammonia:
HOCl + NH₃ → NH₂Cl + H₂O
The resulting chlorine-nitrogen bond stabilizes the chlorine atom. This makes monochloramine a mild oxidant, with a halved redox-potential (ORP) with respect to other chlorine-based disinfectants, like chlorine and chlorine dioxide. Such reduced redox potential carries several advantages, making monochloramine an excellent solution for municipal secondary disinfection.
Why is monochloramine used in municipal water systems?
Its stability and lower reactivity make monochloramine ideal for long-term disinfection. It provides a consistent residual effect throughout the distribution network without rapidly breaking down or forming excessive byproducts.
The main disadvantage of monochloramine disinfection in municipal systems has been nitrification. This requires municipalities to periodically perform Chlorine Burnouts, where free chlorine is temporarily used to disinfect water.
This process helps to eliminate nitrifying bacteria, but it carries many disadvantages, such as:
- Taste and smell complaints from users.
- Increased DBPs concentration in the water.
- Increased corrosion rate of the pipes due to free chlorine being a stronger oxidant
Why choose SANIKILL?
- No nitrification
The high-level technology behind SANIKILL® units allows for precise control of the monochloramine production reaction. The consequent yield of monochloramine production reduces the presence of unreacted precursors, specifically ammonia, avoiding the emergence of nitrification phenomena.
- Eliminate booster stations
Monochloramine`s remarkable stability makes it a long-lasting molecule ensuring disinfection throughout water distribution systems, even in cases of extensive systems with many branches. When correctly generated, it can be effectively distributed reducing or eliminating the need for booster stations.
- Reduced Toxic byproduct
Due to the reduced redox potential monochloramine does not generally react with organic matter present in the water. Hence, regulated disinfection byproducts such as THMs and HAA5 are heavily reduced or eliminated.
- Biofilm penetration
Monochloramine has proven to be effective not only on planktonic microorganisms, but also on sessile populations, it penetrates and destroys biofilms. By targeting essential proteins in microbial membranes, it:
- Reaches deep into biofilms.
- Kills bacteria hidden within.
- Maintains effective residual concentrations without being consumed by outer biofilm layers.
