The amount of water used in an industrial setting is critical for its use in the production of products, longevity of equipment, and also potential regulatory issues. Due to the necessity for a facility to be able to treat massive quantities of process water, it is important to protect equipment, ensure compliance with regulations, as well as minimize the amount of damage done to the environment.
To achieve this, it is necessary to produce consistent results that meet very specific standards while keeping costs down on both the amount of energy consumed and chemicals used.
Fortunately, today there are many new tools available to support a successful AI water management strategy, including the ability to identify and correct problems before they become serious issues using artificial intelligence (AI) based water quality monitoring systems; digital twins; and the ability to test proposed changes to a treatment system without the need to actually make those changes.
In the realm of industrial water treatment, adopting a cutting-edge water treatment system is paramount. This is where AI as a service truly shines, providing advanced analytical capabilities that transform raw data into actionable insights. These intelligent water treatment solutions are key to optimizing processes and ensuring environmental compliance.

Common Pain Points in Water Treatment Systems
1. Changes in raw and process water quality (variable influent) require frequent adjustments to treatment. Therefore, real time monitoring and the ability to adjust treatment systems as needed will be critical to ensure that treatment is both efficient and effective.
2. Mineral build-up (scaling) and biological growth (biofouling) will continue to block filters and reduce the overall effectiveness and increase the maintenance requirements of the system.
3. Stricter discharge limits, increased auditing, and continuous monitoring will create additional regulatory compliance and documentation challenges for wastewater treatment plants. Reliable data and automation will be required to meet new regulatory requirements.
4. Energy usage for aeration, pumping, and solids handling in wastewater treatment is high. By optimizing each of these areas and incorporating renewable energy sources, cost savings can occur.
5. Accurate chemical dosing, safe storage and handling of chemicals are necessary to prevent unnecessary waste and exposure to potential health and environmental hazards.
6. Integrating treatment into production schedules will become increasingly complex due to the integration of treatment into production schedules, while addressing emerging contaminants such as PFAS, pharmaceuticals and microplastics will require advanced technology solutions.
7. Important information related to treatment operations, chemical management and maintenance is typically fragmented between multiple different systems or applications. The lack of integration of this important information will make it challenging to perform an integrated analysis of the entire operation.
The evolution of water treatment technology is rapidly advancing, offering sophisticated tools for every aspect of industrial water treatment. From initial influent analysis to final discharge, a modern water treatment system leverages innovations like digital twins and advanced membrane filtration. This integrated approach ensures efficiency and sustainability.

Modern Solutions: Tools That Deliver Results
AI + IoT Monitoring: Continuous Oversight
Use good sensors to measure in real time. Feed this data into an AI for water quality monitoring. Water treatment systems quality will be monitored continuously through the AI and predictive maintenance. The AI can predict anomalies, future conditions and patterns that may occur. Surprises lessen with less surprises; operations run more smoothly; decision making is better.
Key benefits: Managing variable influent, precise dosing, early leak detection, and predicting equipment failures.
Â
Digital Twins: Safe Optimization
Digital twins create a virtual replica of your treatment plant. By doing so you are able to evaluate scenarios and optimize processes. This provides an opportunity to evaluate changes (i.e., recycle rate, DO concentration) on the digital twin first; this way you can see how they will affect performance prior to applying those same changes to the actual treatment plant. The potential for error is greatly reduced with this approach.
Key benefits: Stable effluent, lower energy consumption, fewer over-corrections, and faster troubleshooting.
Â
Membranes: High Purity Standards
Advanced filtration and membrane technologies handle emerging contaminants effectively. These include ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO).
1. Ultrafiltration (UF): This removes fine solids (2 to 100 nanometers).
2. Membrane Bioreactor (MBR): This combines biological treatment with membrane separation. It provides high-quality effluent in compact systems.
3. Nanofiltration (NF) and Reverse Osmosis (RO): These address dissolved loads, hardness, and micropollutants. RO is vital for high-purity water, while NF handles divalent and multivalent ions.
Important consideration: Membranes need effective pretreatment and AI-driven management. This optimizes cleaning cycles and prevents fouling.
Â
Chemical-Lean Polishing: Targeting Stubborn Contaminants
Chemical-free processes reduce reliance on chemical dosing. Examples include electrocoagulation (EC) and advanced oxidation processes (AOP).
1. Electrocoagulation (EC): This generates coagulants in situ. It reduces the use of bulk chemicals.
2. Advanced Oxidation Processes (AOP): These use methods like peroxide/ozone/UV. They target recalcitrant organic compounds.
Best used when: Conventional methods are not enough, or when you want to reduce on-site chemical handling.
Â
Automation and Control Software: Streamlined Operations
The integration of automation and control software to combine treatment operations with those of a manufacturer can provide for a very consistent operation of the treatment process. The automation and control software will provide recommendations and alerts that are able to be viewed through the use of the current system used by the manufacturer (SCADA, Historians, LIMS, CMMS) as well as provide a one click roll back feature for the user to protect the users from making an error with the use of AI based water treatment system management.
Outcome: Reduced manual effort, clearer operational intent, and increased operator trust.
Â
Energy Optimization: Consistent Savings
Optimizing and investing in the use of energy efficient equipment and optimization of the treatment processes will greatly reduce the amount of energy required to treat the wastewater. The use of smart blowers and DO control, the use of VFD driven pumps, the use of tariff aware pump scheduling, and the use of heat recovery will allow for fixed cost of treating the wastewater to become variable cost.
Furthermore, the integration of AI as a service into water treatment technology is revolutionizing how industries manage their water resources. This allows for predictive maintenance and real-time adjustments within the water treatment system, leading to significant cost savings and improved operational reliability. These comprehensive water treatment solutions are essential for navigating today’s complex regulatory landscape.
