Iron Ore Project: Replaced 100 Membrane Plates + 100 Chamber Plates (200 Plates Total)

An iron ore dewatering site needed a fast, low-risk plate pack replacement within a short shutdown window. Scope included 100 membrane filter plates and 100 chamber plates. The goal was simple: no leakage, stable cycles, and predictable cake moisture after start-up.

Technical Focus

  • Membrane + chamber combination: filtration + secondary squeeze to improve cake dryness consistency.

  • Low-risk replacement method: verified critical dimensions, port alignment, sealing faces, and load/support points—not just part numbers.

Main Challenges & Solutions

  1. Short shutdown window + large quantity (200 plates)

    • Split installation into controlled stages, with plate ID tracking and priority mounting at end plates for early verification.

  2. Abrasive iron ore slurry (sealing is sensitive)

    • Standardized cleaning/inspection of sealing faces, then checked leakage points during first runs (plate edges, ports, filtrate outlets).

  3. Unstable squeeze results on membrane stage

    • Adjusted squeeze logic for repeatable multi-cycle performance and aligned it with cloth condition to avoid “good plates, poor results.”

  4. Worn old plates made reference dimensions unreliable

    • Used multi-point measurement and interface-based verification to prevent misalignment and incorrect sealing compression.

Sistema de flotación por aire disuelto de alta carga – SIGMADAF FPAC

El equipo DAF FPAC es ideal para trabajar con caudales pequeños y medianos, que contienen elevadas cargas de contaminantes. Además, son el modelo más indicado para espesamiento de fangos. Son equipos con mucha superficie libre donde acumular el lodo flotado.
