ABOUT MST

Master Technology (Wuxi) Co., Ltd.

Founded in 1958, the company has collaborated with Dransfield Company of the United States (Krofta, 1992–1999) to specialize in the manufacture of dissolved air flotation equipment. Led by the original KROFTA chief designers, Dr. James Madison and Dr. Peter Keatinge, the team developed next-generation shallow-dissolved-air-flotation products—including the Shallow Ion Flotation and Dual-Ion Flotation series—serving more than 6,000 enterprises. (KROFTA was established in 1947 as a global leader in DAF technology research and development, with its headquarters in Great Barrington, Massachusetts, USA.) Ion flotation has brought about a disruptive transformation in DAF technology; its outstanding performance has swiftly enabled the upgrade of KROFTA’s original product line, establishing the company as a globally recognized provider of advanced separation-and-clarification systems and DAF solutions. Leveraging Master’s integrated separation-and-clarification technologies and equipment capabilities, the company now delivers nearly 20,000 high-efficiency, stable ion-flotation systems to markets worldwide.

Does the dissolved air flotation unit require chemical dosing? Regarding the question of whether a dissolved air flotation unit needs chemical dosing.

Dissolved air flotation (DAF) units are commonly used in wastewater treatment and solid–liquid separation. They operate by leveraging the buoyancy of microbubbles to lift suspended solids to the water surface, thereby achieving solid–liquid separation. However, whether chemical dosing is required for a DAF unit depends on the specific application and process requirements; there is no one-size-fits-all answer.
