A cutting-edge dewatering system is now operational at a Wisconsin dairy, demonstrating a significant stride in sludge management technology. This installation marks a key advancement in addressing the unique challenges of processing mixed aerobic and anaerobic sludge.
Project insight
Facing the need for an efficient method to dewater a sludge blend with only 1.5% dry solids, the dairy embarked on a modernization initiative. After extensive jar and pilot tests, Esmil’s engineering team identified the MDQ-403 — a robust 16-inch diameter, three-drum press system — as the ideal solution. The target was clear: achieve a consistent flow rate of 55 gpm while producing a cake with over 15% dry solids.
Equipment and installation highlights
To meet these goals, the following equipment was delivered and installed on site:
- Multi-Disc Screw Press MDQ-403 CLS
- Polymer feeder
- Flowmeter
- Main control panel
- Sludge feed pump
- Control panel for the sludge feed pump
Esmil’s expert service team managed the installation with precision, ensuring all platforms, feed lines, drains and electrical systems were correctly set up and rigorously tested. The startup process was smooth, with no significant technical hitches, confirming the system’s readiness for full-scale operation.
Overcoming operational challenges
The dairy’s primary challenge was efficiently dewatering a low-solids sludge mix without compromising on throughput. By gradually increasing the infeed to reach the desired 55 gpm, Esmil’s team confirmed that both mechanical and electrical components functioned flawlessly. The system not only met the rigorous performance criteria but also produced a cake exceeding the required 15% dry solids, thereby affirming the system’s effectiveness.
