Slop Water Cleaning

Drilling with both oil-based mud and synthetic based mud generates waste streams, often referred to as ‘slop mud’ or ‘slop water’, which are produced when an oil/synthetic/diesel-based drilling fluid becomes contaminated with water. Hydrocarbons render these slops ineligible for overboard discharge.

Wärtsilä Slop Water Cleaning is designed to clean mud or water contaminated with slop or drilling mud from drilling rigs and drilling ships. The processing principles are based on a combination of chemical treatment and dissolved air flotation. The chemicals flocculate and bind together particles, making them easier to separate, which then allows flotation by dissolved air to separate both particles and oil from the water. The result is clear water free of particles and oil, acceptable to be discharged to the environment or reused.
