NHD Releases Technical Guide on Preventing Solids Carryover and Leakage in Vertical Filter Presses

MINHANG, China - Aug. 3, 2026 - PRLog -- Summary: Solid-liquid separation equipment maker NHD publishes a troubleshooting guide addressing the two most common operational faults in vertical filter presses, offering root-cause analysis and field solutions for plant operators.

[City, Country] — August 3, 2026 — NHD, a manufacturer of solid-liquid separation equipment, today announced the release of a new technical guide addressing solids carryover and leakage, the two most frequently reported operational issues in vertical filter presses across mining, metallurgy, and chemical processing industries.

Solids carryover occurs when solid particles escape with the filtrate, clouding the filtrate and causing material loss. Leakage occurs when slurry or filtrate escapes through sealing points, filter plate connections, or hydraulic fittings, creating safety and environmental hazards on the plant floor. According to NHD, both issues typically trace back to one of three root causes: filter cloth condition, seal integrity, or operating parameter control.

The new guide breaks down the common causes behind each issue — including filter cloth damage, incorrect mesh sizing, seal aging, and insufficient hydraulic clamping force — and pairs each with a corresponding field solution. It also includes a quick-reference troubleshooting table and a prevention checklist designed to help maintenance teams catch problems before they affect production.

"Most carryover and leakage issues are preventable with the right inspection routine," said an NHD engineering representative. "We put this guide together so operators can diagnose the root cause quickly instead of guessing, and get the equipment back to full output with minimal downtime."

The guide also outlines how NHD's HDLY fully automatic vertical filter press addresses these failure points by design, including a four-column high-rigidity frame, hydraulic clamping up to 1.6 MPa, horizontal filter cloth placement for uniform cake thickness, and built-in self-diagnostic alarms. NHD additionally operates its own filter cloth production facility, using imported DORNIER looms from Germany, to help customers select or customize filter cloth matched to their specific operating conditions.
