Case Study: Western Hancock Utilities, Indiana

At Esmil, we pride ourselves on delivering cutting-edge solutions for the most challenging wastewater treatment scenarios. We are pleased to share our success story with Western Hancock Utilities in Indiana, where our expertise in dewatering waste-activated sludge (WAS) made a significant impact on operational efficiency.

Challenge:

Western Hancock Utilities faced the pressing challenge of efficiently dewatering WAS from their oxidation ditch at the wastewater treatment plant. Achieving optimal dewatering results and minimizing polymer consumption were key objectives. The system was sized to handle up to 185 GPM at 1.5% initial DS content waste-activated sludge. The minimum cake DS requirement was 18%.

Solution:

Esmil stepped up to the challenge by offering an on-site pilot test, which allowed us to gather solid data points and identify the most efficient polymer and polymer consumption levels. Our commitment to precision and excellence shone through in every aspect of the project:

  1. Pilot Test Success: Our pilot test yielded stellar results, demonstrating our ability to achieve the desired levels of dewatering efficiency and dry solids concentration.
  2. Comprehensive Dewatering Package: Esmil provided Western Hancock Utilities with a comprehensive dewatering solution, including:
  • Esmil multi-disc dewatering press with advanced controls.
  • A polymer feeder for precise chemical dosing.
  • A sludge pump equipped with a flow meter for accurate monitoring.
  • Two Esmil shaftless screw conveyors to efficiently transport dry cake away from the press discharge to a designated dumpster.
  1. Smooth Start-Up: Our team ensured a seamless and successful start-up of the dewatering system, all completed within the designated timeframe in July of 2023.

Results:

Thanks to Esmil’s expertise and state-of-the-art dewatering technology, Western Hancock Utilities achieved all that they required and more at their wastewater treatment plant. Our commitment to data-driven solutions allowed us to optimize polymer consumption, minimizing operational costs while maximizing performance.
