Calculating Chlorine Dosage, Feed Rate, and Residual and Chlorination Estimator

Chlorine is a useful disinfectant for wastewater treatment and can be introduced in liquid, gas, or solid form. The required chlorine dosage for wastewater treatment depends on a variety of factors including the chlorine demand of the wastewater, the availability of de-chlorination, detention time, and regulatory limits for chlorine residuals in a systems wastewater discharge. To calculate the chlorine demand of your system, a system needs to record their feed rates of chlorine and analyze the residual chlorine in their system after chlorine treatment… Read More in the available PDF 

The Chlorination Estimator is a simple excel tool that operators can use to calculate their chlorine needs. By inputing a few simple wastewater parameters operators can calculate the chlorine feed rate needed to achieve a desired chlorine dosage, the required chlorine dosage required based on the desired chlorine residual and known chlorine demand, and likely chlorine residual.
