What is terry flotation?
Flotation Flotation is a process using air bubbles to separate materials based on their relative affinity to the water. Bubbles bear the agent and hydrophobic materials to the top of the tank where they can be removed. Flotation flotation is used for more than a century in mining operations to separate valuable materials from dug ores. More recently, foam fleets are used to treat contaminated water. The agent is used to increase the hydrophobic properties of the required compounds that separated them from residual substances that are hydrophilic. The mixture is upset to ensure even scattering. The tendency of hydrophobic materials to adhere bubbles is transmitted to the surface of the tank. Above are bubbles bearing a burden of minerals or foam. Segregated compounds that are solid go through the next step of processing to separate from air bubbles and reagent residues. The residual hydrophilic material mixed with water in the tank, also known as the gang, is exhausted.
Mining use of foaming fleet includes the separation of many different types of compounds including sulphides, silicates, phosphates, coal and iron ore. The agents or surfaces are carefully selected to accurately create the separation effect required for a particular ore or a combination of ores. Many factors affect the quality of the department; These include the speed of the flotation, the size of the ore particles, the density of the ore and the water mixture and the amount of air used. The recent use of the process separates ink from recycled paper.
As a method of treatment of contaminated water, foam foam is particularly suitable for separation of water containing oil products. This process is also known as dissolved air fleet. The steps differ slightly from the separation of mining ore.
Water is first treated with chemicals to increase the adhesion of contaminants on air bubbles. Part of the water is pumped and via the retention tank, where the compressed air is added. The material is circulated back tofleet cells where air is based on suspension as very small bubbles; It then carries oil contaminants and suspended solids to the cell surface to be forgiven. Treated water is pumped and usually sent for further filtration or other treatment.
