Esmil Group has successfully completed another project, which involved the supply and commissioning of a multi-disc screw dewatering unit of the MDQ series at a wastewater treatment plant in Covington, Ohio. The proposed solution fully met the customer’s needs, and the results obtained once again confirmed the efficiency and high performance of Esmil’s innovative sludge dewatering technologies.
Introduction
The Covington wastewater treatment plant recently underwent a major upgrade to improve sludge treatment efficiency. With the growing need for more efficient dewatering of aerobically treated activated sludge, the facility sought a solution that would not only meet current operational challenges but also be adaptable to future changes. In collaboration with Esmil, the facility implemented a multi-disc screw dehydrator, a state-of-the-art sludge dewatering technology designed to meet both current and future performance requirements. This provided reliability, efficiency, and flexibility, ensuring the sustainability of the treatment process for many years to come.
Esmil Solution
Esmil specialists, anticipating a possible increase in the capacity of the treatment plants in the future, initially recommended the MDQ-401 multi-disc screw dehydrator model as the optimal solution for sludge dewatering. However, taking into account the prospect of further expansion of the OS, the Esmil group included the possibility of installing an additional drum, which led to the evolution of the configuration to the MDQ-402(1) CLD model. Thanks to this forward-looking approach, all the necessary electrical and mechanical components were integrated in advance, which will allow for easy and seamless modernization of the system if necessary. The result? A perfectly thought-out solution that meets both current and future operational challenges.
Equipment installed at the facility
The following key components were supplied and installed for this project:
- Multi-disc screw dewatering machine MDQ-402(1) CLD
- Control cabinet
- Polymer dispenser
- Flowmeter
Installation and commissioning were carried out by Esmil service specialists, ensuring a smooth and efficient project implementation. The team conducted a thorough inspection and comprehensive testing of all key parameters before starting the sludge dewatering process, ensuring reliable and stable operation of the equipment.
Key features of MDQ technology
- Modular and scalable design – The MDQ multi-disc screw dewatering unit is designed to meet both current plant needs and future plant load growth. The MDQ-402(1) model provides additional space for a second dewatering drum, allowing for easy capacity expansion as capacity requirements increase.
- Exceptional dewatering efficiency – MDQ technology provides high throughput and consistently produces sludge with dry matter content exceeding industry standards, improving the quality of the final product.
- Increased operational reliability – By integrating all key electrical and mechanical elements into the design, the MDQ sludge dewatering unit guarantees stable operation, reducing the risk of downtime and minimizing maintenance costs.
- Energy Efficiency – Optimized for maximum performance, MDQ technology reduces operating costs while providing high dewatering efficiency and reducing energy consumption.
Productivity
After a successful start-up, the system quickly reached the planned capacity of 6.8 m³/h, demonstrating an outstanding result of over 100 kg of dry solids/h in the dewatered sludge. The dry matter content of the dewatered sludge not only exceeded the client’s minimum requirements, but also significantly exceeded the target indicators, confirming the exceptional efficiency and reliability of the technology.
Conclusion
The dewatering system and related equipment supplied by Esmil exceeded the customer’s expectations. Thanks to the high professionalism of the Esmil service team, which took over the management of all mechanical and electrical processes, the system was quickly and smoothly integrated into the production process. This successful installation further strengthens Esmil’s reputation as a reliable supplier of highly efficient technological solutions. Another successfully implemented project in our portfolio!
