Nitrification Control Process
Nitrogen exists in several types, with the primary influences on water quality management being total nitrogen, ammonia, nitrite, and nitrate. In water treatment systems without aeration there is a greater likelihood of total nitrogen and ammonia building up while in aerated water treatment systems the buildup of nitrite and nitrate can be more of a concern. Left alone, these types of nitrogen can result in excessive growth of algae, plant matter, and cyanobacteria.
Nitrification is the term used to describe the biological oxidation (breakdown) process of ammonia to nitrate to nitrate. Denitrification then takes another step converting nitrite into nitrogen gas which can escape the water body into the atmosphere.
The reaction looks like this:
Nitrogen Waste —->NH3 (ammonia) —->N02 (nitrites) —-> NO3(nitrates)—-> N2^ (nitrogen gas)
Nitrification and denitrification is performed by various species of bacteria and like any living organism these bacteria function best in certain environmental conditions. Some of the environment factors that influence the bacteria include pH, oxygen, temperature, age of the wastewater system (sludge age), concentration of heavy metals and the design and operation of the wastewater treatment plant.
Maintaining stable environmental conditions plays a big part in the nitrification process but this can be difficult to do in a wastewater treatment plant, especially when there can be peaks and troughs in terms of wastewater inflows or if the plant operator has no control over what comes into the system e.g a chemical spill.
Our nitrification control products contain highly concentrated blends of both nitrifying and denitrifying bacteria to enable wastewater treatment systems to quickly get back online after a crash, balance out peaks and troughs of inflows or simply help maintain a well functioning wastewater treatment system.
