Thickeners & Clarifiers Suppliers, UAE
Thickeners and clarifiers are solid-liquid separation devices that concentrate mineral slurries and clarify process water for reuse in mining and mineral processing plants. They include conventional, high-rate, and paste thickeners, as well as lamella and tube-settler clarifiers. In the GCC's water-scarce environment, efficient thickening and water recovery is both an economic necessity and a regulatory requirement for mining operations.

Thickeners and clarifiers are essential unit operations in mineral processing that separate solids from liquids to recover process water, produce pumpable underflow slurries for tailings disposal, and clarify overflow water to a quality suitable for recirculation. Conventional thickeners use gravity settling assisted by flocculant addition, while high-rate and high-density thickeners achieve faster settling and higher underflow densities through advanced feedwell and rake designs. Paste thickeners produce a non-segregating, stackable underflow that enables dry-stack tailings disposal.
In UAE and Saudi Arabia mining operations, water recovery is a critical economic and environmental priority given the region's extreme aridity. Thickeners recovering 85 to 95 percent of process water for recirculation can dramatically reduce freshwater intake and operating costs. Procurement managers should evaluate thickener diameter, unit area requirements (square metres per tonne per day), underflow density targets, overflow clarity specifications, and flocculant type and dosage. Paste thickeners are gaining adoption in the GCC for their ability to eliminate conventional tailings dams, reducing both footprint and long-term environmental liability.
When sourcing thickeners, confirm that suppliers provide settling testwork, thickener sizing calculations, and flocculant selection trials based on representative ore samples. Rake drive torque capacity, lifting mechanism, and overload protection are important mechanical specifications. Clarifiers for aggregate wash plants and quarry water treatment are also available from regional suppliers. Turnkey packages that include the thickener tank, mechanism, feedwell, flocculant plant, and underflow pumping system streamline procurement and ensure compatibility.
