SupaVac Case Study – Mill Water Sludge Pond Clean-out

Mobile solids transfer pump system vacuum recovered tons of settled sludge from mill water sludge pond with 1,350 meter zero-leak discharge for disposal, all on one simple operation


The Challenge

This large mill water sludge pond required cleaning of over 3,000m3 of thick, 4.5 SG settled abrasive, corrosive sludge and hard solids. Dredges and excavators could not be used because of concerns over damage to the pond liner. The solids were to be discharged 1,350 meters away into the mine sump for disposal. And the only access to this remote nickel mining operation in northern Canada was by air or water.


The Start

After site meeting with mill engineering, operations and environmental personnel plus Bob Spicer, managing director of Spicer Solution Providers (2sp) Inc., the contract was awarded. Three SV250V-600 pumps, custom accessories to protect the liner from damage, spare parts, 5,700 meters of 100mm SDR11 hdpe piping, special suction, discharge, and compressed air hose assemblies were mobilized to the site by ship. Two supervisors from 2sp rotated onsite, first for training and the installation of piping and hose and positioning of pumps; and then for the daily operation and maintenance as required


The Completion:

The operation was completed on time and on budget, allowing the pond liner to be inspected and repaired, and zero environmental or safety incidents were reported.


Supavac® SV pump models and systems provide solids transfer rates from 8 to 50 m3/h and higher. Mobile units are compact and fully enclosed for zero discharge and X-P environmental compliance/ATEX Zone II & CE Conformity. Complete pump systems are available for rental and purchase anywhere, some with the option to recover a large portion of rental paid towards the purchase price. Onsite startup supervision and training is available.
