In the metalworking industry, to carry out the galvanized iron parts and steel preservation process takes place in which the parts are immersed in an aqueous solution of ferric chloride where ferrous chloride and hydrochloric acid are used to remove impurities such as stains and remove or clean steel slag. In this process the acid is depleted until there are no clean parts and it becomes spent acid which is a common contaminant in industrial effluents. These compounds do not degrade efficiently through conventional methods of treatment, and also exhibit high degrees of toxicity, causing damage to the environment and human health. Therefore, this research will evaluate the use of picklingacid as a coagulant in synthetic wastewater at a laboratory level. This research will feature four stages of development, characterization, pre-testing, testing and analysis of results. The work to be performed in each of these phases will be done through pilot testing, with each process documented in a laboratory. The water sample named herein (pickling acid) refers to the industrial waste water from the pickling process of the company Polyuprotec S.A Prior to sampling this is mixed in order to have a homogeneous sample.Key Words: Pickling, coagulant, synthetic water, floc, jar test
