Why Fixed Dosing Often Wastes Chemicals?
 
Water utilities have, until recently, used fixed chemical dosing to treat raw water. This involves adding coagulants, disinfectants, and pH regulators in amounts decided by operators or lab tests. This method rarely eliminates overdosing, however. If the characteristics of the raw water change – as they frequently do during heavy rain or at certain times of year – an overdose of chemicals may be wasted or prove insufficient to the task. Artificial intelligence can help to overcome this problem, but a crucial question is whether the changes it makes can reduce chemical wastage whilst maintaining compliance with water quality standards.

How Predictive Control Systems Work?
 
How the system works depends on the technology used. Many AI-controlled water treatment plants have an array of sensors that monitor variables such as turbidity, pH, conductivity, and residual ...
... disinfectant levels in the water. These are combined with calculations of the flow rate to provide the information needed to create a predictive model of the plant. This enables operators to enter figures representing the desired outcome at various stages of the process, examine suggested adjustments, and make any changes that they feel are necessary.
 
Measuring the Chemical Savings
 
The level of chemical savings in each case is simple to measure – many plants that have implemented an AI system report that they have seen coagulant and chlorine use reduced by up to 50% or more. Reduced use of chemicals has benefits beyond the cost savings – it should also lower the risks associated with storage and transportation and reduce costs associated with any surplus chemical waste.
 
Keeping Water within Safety Standards
 
Compliance is a major concern for any water utility, since potable water is subject to strict standards. In the U.S., this usually means conforming to standards set by the Environmental Protection Agency. Water must be treated to remove turbidity and achieve a satisfactory level of disinfection to remove pathogens, and an AI that reduces chemical use too far risks compromising either of these. Because of this, operators of an AI-controlled system should also set hard limits for all chemical additions and provide warnings or switch to a traditional control system if any of these are reached.
 
Why Sensor Data Quality Matters?
 
Another factor that determines an AI’s efficacy is the quality of the data it uses. If operators make incorrect or inconsistent assumptions about the data provided by sensors, the model will use them without question. It is therefore essential to have proper procedures for checking and calibrating the sensors and reviewing the assumptions that the model makes.
 
Keeping Operators in Control
 
Although it can make excellent suggestions, an AI system should always be used as an aid to operators rather than a replacement for human judgement. A utility that is considering adopting this technology should test it on a small scale and have clearly defined criteria for measuring the reduction in chemical use and water quality before committing to a full rollout. By treating it as a tool to reach a specific set of targets, they can ensure that the new system complements existing procedures and maintain the high level of safety expected from any public water supply.
