A hydrocyclone filter Model-ECF is a device used to separate sand and other solid particles from a liquid mixture. It works by using the centrifugal force created by a fast-moving fluid flow. The fluid enters the top of the device and spins rapidly, causing heavier particles to be thrown to the outer edge of the bowl. The particles are then collected in the collection chamber at the bottom of the device, while the clean fluid exits from the top. Hydrocyclone filters Model-ECF are used in a variety of industries, including mining, oil and gas, and wastewater treatment.
