Wastewater Terminology - An Important Term Relating to the Disinfection Process
Wastewater treatment has emerged as one of the green technologies or the most environment friendly technology.
Since this is an industry that is only now gaining in popularity, some of the wastewater terminology related with the disinfection processes are not easily understood by all.
In this article I discuss an important term associated with municipal wastewater disinfection.
Disinfection (Concentration-time Product) - The concentration-time product is an equation written as K = C^N T.
This equation represents the relationship between the concentration of the disinfecting agent used in the wastewater during the disinfecting process and the period of time it has to be in contact with microorganisms to be able to eliminate the microorganism from wastewater, known simply as the contact time.
This relationship is also dealt with by Watson's Law.
The K in the above equation represents a constant value for the reaction.
This only varies according to the microorganisms and is the time that is required to keep the disinfectant in contact with the microorganism for elimination, under conditions suitable for the action.
This value is written as mg/l.
min.
The unit C represents the concentration level of the disinfectant in wastewater.
This is measured in mg/l.
The unit N is called the dilution coefficient or the empirical constant.
The unit T (measured in min.
) represents the period of time taken by the disinfecting agent to eliminate a significant number of the microorganism in wastewater.
The effectiveness of the disinfectant can be represented using the term Ct, where C would be the concentration level of the disinfectant and t would be the time required for it to stay in contact to eliminate a desired quantity of the contaminating microorganism under certain pH and at a certain temperature.
When actually disinfecting, the value of N is almost unity.
Hence this value is also important while determining the disinfectant's concentration level as well as the time it should stay in contact with the contaminant.
When the values C, T and N are plotted in a graphical x-y plane, N is seen to form a straight line.
This is one of the most important of the wastewater terminology used in the wastewater industry.
This process is part of the basics for anyone wanting to know more about the treatment methods used in municipal wastewater disinfection process.
In my next article I will discuss two more such terms.
