Esmil Group successfully completed another project, involving the delivery and commissioning of the MDQ series Multi-Disc Screw Press at the wastewater treatment plant in Covington, Ohio. The solution provided by Esmil fully met the client’s needs, and the results achieved confirm the effectiveness and efficiency of the tailored technologies.
Introduction
The Covington Wastewater Treatment Plant recently undertook a series of upgrades to enhance its sludge processing capacity. Faced with the growing demand for more efficient dewatering of aerobically digested waste activated sludge (WAS), the facility sought a solution that could not only meet their current operational needs but also accommodate future growth. Partnering with Esmil, the plant deployed a Multi-Disc Screw Press system, designed specifically to handle both present and future throughput requirements, ensuring long-term operational efficiency and flexibility.
Esmil’s solution
Esmil’s specialists, considering the potential future increase in the treatment plant’s capacity, initially recommended the Multi-Disc Screw Press MDQ-401 model as the best fit for dewatering. However, with future capacity increases in mind, Esmil reserved an additional spot for an extra drum, evolving the configuration into the MDQ-402(1) CLD. This forward-thinking design ensures that all necessary electrical and mechanical provisions are already in place, allowing for an easy upgrade when the need arises. The result is a perfectly engineered solution that meets both current and future operational demands.
Equipment Installed at the Facility
For this project, the following key components were supplied and installed:
- Multi-disc Screw Press MDQ-402(1) CLD
- Control Panel
- Polymer Feeder
- Flow Meter
The installation and commissioning were carried out by Esmil service specialists, ensuring a seamless process. The team conducted a thorough review of the extensive startup checklist before proceeding with the commencement of sludge dewatering.
Key Features of MDQ Technology
- Modular and Scalable Design: The Multi-Disc Screw Press MDQ series is designed for both current performance and future growth. The MDQ-402(1) model includes an extra drum space, providing an easy upgrade option as capacity demands increase.
- Outstanding Dewatering Efficiency: MDQ technology ensures high throughput while consistently producing cake with dry solids content that surpasses industry standards.
- Enhanced Operational Reliability: With all essential electrical and mechanical elements integrated into the design, MDQ systems guarantee smooth, trouble-free operation and reduce maintenance costs.
- Energy Efficiency: Optimized for performance, MDQ technology helps reduce operating costs while maintaining robust dewatering results.
Performance
Following successful commissioning, the system quickly reached the required 6,8 m³/h, achieving an impressive output of more than 100 kg DS/hr in cake form. Remarkably, the cake’s dry solids content exceeded both the minimum requirements and target specifications, highlighting the system’s exceptional performance.
Conclusion
The dewatering system and supporting equipment supplied by Esmil have once again exceeded customer expectations. Thanks to Esmil’s expert service team, who managed all mechanical and electrical aspects, the system was swiftly integrated into production with no issues. This successful installation further solidifies Esmil’s reputation for delivering reliable, high-performance solutions—another success story to add to our portfolio!
