Re-use of Mine Process Water, General Purpose and Gland Service Water, PMG Mine – Rustenburg

Kleerflo Suction (Demand Side) Filter

Client: PMG Mine
Industry: Mining – Final Filtration – Process Water and Gland Service Water
Region: North West Province
Product: KFS 7E3/250/10-08/25
Installation Date: 2008

Challenge

  • Mines recycle process water and use some of it for Gland Service Water (GSW).
  • The recycled process water may have high suspended solids levels.
  • The suspended solids cause damage to equipment.
  • Specifically, dirty GSW will reduce the life of the slurry pump stuffing box components and gland packing.
  • For this application, filtration is required on the suction side of the pump that supply process water to the plant.
  • Filtration on the demand side of pumps runs the risk of starving the pump of water, especially during the self-cleaning (backwash) cycle

Application

  • Final Filtration / Filtration of Process Water / Gland Service Water / installed on suction (demand-side) of the pump that deliver the water to the plant.

Solution

  • Design of the KFS filter is rooted in the principle of inherent simplicity:
    • no rotating parts – very few moving parts
    • no close tolerance elements
    • no electric motor
    • high quality, durable, stainless steel wedgewire screens.
  • KFS filters are designed specifically for tough industrial applications.
  • Low maintenance- and running costs.
  • Long uninterrupted filter runs, efficient filtration and filtrate in compliance with client acceptance standards.
  • Integral processing of oversized particles – so no manual pre-screens required.
  • KFS filters are designed to provide filtration on the suction (demand) side of high-pressure pumps without the risk of starving the pumps during self-cleaning (backwash) cycles.
  • The mine installed a Kleerflo Suction Filter – model KFS 7E3/250/10-08/25.
  • Filtration provided at 250µm.

Results

  • Cleaner process water resulted in lower maintenance costs on pumps and plant equipment and a decrease in downtime.
