The MD1 multi-diaphragm metering pump uses Hyperdrive technology to alternate between dual diaphragms, delivering smooth, continuous chemical feed — even with off-gassing fluids like peracetic acid and sodium hypochlorite that stall other pumps. A 10,000:1 turndown ratio and exclusive DiaFlex diaphragms handle low-flow, high-precision dosing without the tube assemblies peristaltic pumps require.

This webinar will talk about turbidity spikes related to turbidimeter sampling, measurement parameters, and reporting along with approaches for troubleshooting and resolving turbidity spikes. You’ll learn: • The impacts common interferences have on turbidity readings — especially those pesky bubbles • Best practices for sampling and the role instrument design plays • Capturing and tips on how to interpret what you’re seeing Click here for the webinar

When Sunbury Wastewater Treatment Plant needed to replace a belt filter press that had been taken out of service, the facility had an opportunity to reconsider its approach to sludge dewatering. Instead of installing another belt-based system, the plant selected an Esmil MDQ-504(3) multi-disc screw press. Commissioned in August 2026, the new system represents a clear transition toward simpler, more automated dewatering with lower day-to-day demands on plant personnel.

SEEPEX was approached by Hamlett Environmental to assist with a critical issue at a wastewater treatment facility in Michigan. The plant was experiencing a mechanical failure involving a seized plug-in shaft within the output shaft of a gearbox. Due to limited technician availability at the time, the customer shipped the affected pump directly to SEEPEX for evaluation and repair. Despite SEEPEX’s efforts, the plug-in shaft could not be removed.

Our industry moves fast. New equipment hits the market, crews adapt to changing regulations and infrastructure demands, and municipalities continue searching for smarter ways to maintain treatment plants and sewer/water systems. To help readers stay caught up, we’re rounding up some of the most-read stories from September on Treatment Plant Operator.

Learn about unique aspects of measuring high-range turbidity samples with portable turbidimeters. Turbidity can be useful as an indicator of the effects of runoff from construction, agricultural practices, logging activity, discharges and other sources. But measuring high levels of turbidity consistently and accurately can be a challenge for a variety of reasons.

The City of Fallon, Nevada's aging duplex diaphragm pumps struggled to reliably dose 50% sodium hydroxide for pH adjustment and arsenic removal, demanding constant upkeep. Blue-White replaced them with a wall-mounted duplex skid built around two FLEXFLO M3 peristaltic pumps — eliminating priming issues, reducing maintenance, and adding built-in tube-failure detection for safer operation.

From Irish whiskey to Kentucky bourbon, German bier to U.S. microbrews, and from California to French wineries, SEEPEX is helping these crafts increase productivity and yields in new ways. Whether it is conveying viscous mash, ingredients, or low shear pumping of the end product, SEEPEX can do the job. The distilling/brewing process produces several byproducts, one of which is spent grain and draff which typically contains 75%-80% moisture.
