Mud Disposal California – Hydro Excavation

केस स्टडी

Challenge

A California electrical utility performing regular maintenance performs regular hydroexcavation work. The resulting soil slurry must be tested before disposal. Transport and disposal of this liquid waste is very costly. On this occasion, there were 17,000 gallons to dispose of.

Solution

MetaFLO’s MF006 solidification reagent quickly and easily accelerates the solidification process eliminating the need for costly vacuum truck transportation and liquid waste treatment. MF006 is added at an extremely low dose, typically less than 1%.

Result

The solidified mud was tested and met all requirements for beneficial reuse as a clean fill. This material was picked up by a nearby business in need of clean fill resulting in the complete elimination of disposal cost offering an ideal solution for mud disposal California.

Challenge

Vale owns and operates a mining site in Northern Ontario, Canada. Through their mining and refining activities they produce a sludge waste by-product. The clients were in need of an efficient excavation and transportation solution to get this sludge to their off-site landfill.

Date

End of September 2018  -  Mid October 2018

Solution

During the bidding process, MetaFLO was engaged to provide an optimal blend and dosage rate to achieve the solids criteria required for excavation and transportation of the sludge. Using analytical data, MetaFLO estimated a dosage rate of 1.1% by weight (based on a high moisture content). Large mixing bins were recommended for increased surface contact and efficiency during the bucket mixing process. No sample was available at this time.

Result

Tervita Corporation utilized MetaFLO reagent to solidify approximately 4,000 m3 of sludge. Two 35m3 bins were staged on site and were loaded with a composite of “heavier” and “lighter” sludges. The originally estimated dosage rate was accurate as actual treatment averaged approximately 30lbs of MetaFLO MF006 reagent per m3 of sludge. All material was safely shipped to Vale’s off-site landfill. The job was completed on time.
