For Reservoir Maintenance Even the most efficient water treatment facilities cannot filter out 100 per cent of all micro sediments and water treatment media residue. Deposits will accumulate in the reservoir and in time may substantially reduce capacity and water quality. With 20 years of dredging experience, Dominion Divers Ltd. has learned to cope with many unforeseen circumstances. We have worked in numerous lagoons that have contained more than just municipal waste.
Lime is used in many potable water treatment plants as part of the treatment process.
The residue is pumped into the sewage lagoon where it precipitates. This combines with mud and sand that can enter the force main through ruptures and creates a solid mass that can be walked on. Large lagoon projects completed by Dominion Divers Ltd. include a 10-acre lagoon at Humbolt, Sask. No water storage area is too large or too small. Advantages Reduces water treatment costs Fast cost-effective removal of sand, silt, alum sludge, filter media residue, etc.
