Scale formation is one of serious problems for oil industry and water treatment. Thanks to well-developed technologies today these is a wide spectrum of solutions, consisting of chemical inhibitors, evaporators and reverse osmosis membranes. SAR Treatment AS investigates different acceptable for the plant solutions to the calcium carbonate scale formation. This work presents overview of different options for SART AS, and makes stronger accent on a sand cyclone usage. The experiments and measurements of chemical parameters of cyclone treated water show that the cyclone efficiency in scale removal is significantly high. Also the experiment demonstrates that the cyclone has its own disadvantages, which should be taken in account. Most crucial of them are biomass removal and absence of the dewatering mechanism for the sand cyclone. According to the SART AS position, the sand cyclone can be used at the plant as scale removal equipment provided some necessary technical changes.
