WASTEWATER TREATMENT THROUGH THE FLOTATION PROCESS
Journal Title: ISB-INMA TEH AGRICULTURAL AND MECHANICAL ENGINEERING - Year 2017, Vol 0, Issue 1
Abstract
Water purification is a complex process of retention and neutralization of dissolved colloidal or suspended solids present in industrial and urban wastewater which is not accepted in the aquatic environment where the spillage of treated waters is made and which enable the restoration of physical chemical properties of water before use. Waste water treatment comprises two major categories of successive operations, namely: retention or neutralization of the noxious or recoverable substances present in the wastewater, respectively processing of the material resulting from the first operation. Flotation is the process of entraining particles suspended in a liquid at its surface, with the help of gas bubbles adhering to these particles. The basis of this process is the formation of "light particles + air or gas bubbles" associations, to be transported to the surface of the flotation basin, forming foam that is removed by various processes.
