5 Strategies to Reduce Costs and Improve Efficiency in Wastewater Treatment Plants

In the face of the escalating global water crisis, wastewater treatment plants play a critical role in ensuring reliable and efficient water management. However, many operators face challenges due to outdated practices and equipment, resulting in increased operating costs, prolonged downtime, and decreased productivity. To address these concerns and enhance the efficiency of wastewater treatment plants, Allflo, a leading supplier of pumps for the water and wastewater industry, offers five intelligent strategies.

1. Conduct a comprehensive equipment assessment: Benchmarking is an essential practice in all industries to set and achieve performance targets. By analysing historical data, plant managers and operators can compare their current performance with baseline measurements, identify performance gaps, and develop strategies to overcome them. The Water Resource Foundation’s self-assessment checklist is a valuable tool for evaluating a plant’s efficiency and performance.
2. Perform a pump audit: Pumps are crucial components in wastewater treatment plants, but many older plants use oversized pumps designed for peak flow conditions. However, the actual flow in these plants varies depending on system and seasonal demands. This mismatch leads to energy inefficiencies and increased costs. Therefore, conducting a pump audit to right-size the pumps based on actual flow requirements can significantly improve energy efficiency and reduce wastage.
3. Opt for Variable Frequency Drives (VFDs): Constant speed pumps often consume more energy and water than necessary. Retrofitting wastewater pumps with VFDs allows for variable speed control, matching the pump’s output to the water supply’s demands. This approach offers several benefits, including reduced energy consumption, decreased water wastage, and extended pump lifespan due to fewer on-and-off cycles. Studies have shown that VFDs can reduce pump energy use by up to 50%, contributing to both cost and water savings.
4. Embrace Smart Technology: Integrating smart metering solutions and advanced monitoring systems into wastewater treatment plants can enhance operational efficiency and reduce waste. Real-time data collection and analysis enable proactive decision-making, allowing operators to optimize pump operations and detect issues promptly. Smart metering eliminates the need for manual readings, providing accurate consumption data for better management and performance monitoring.
5. Evaluate and upgrade technology: A comprehensive analysis of the technology deployed in wastewater treatment plants is crucial for identifying and addressing inefficiencies. Infrastructure audits can help pinpoint areas where upgrades or replacements are necessary. For instance, replacing outdated backwash filters with a dual-layer filtration system can significantly reduce water consumption. By embracing innovative technologies, plants can improve their overall efficiency and reduce costs.
