Treating water generally means removing any solids, impurities, pollutants or micro-organisms it contains. This is not a single process, but a series of stages designed to obtain purified water that can be entirely reused, thereby considerably reducing expenditure and costs, especially in those sectors where completely recovering the liquid part is indispensable. Della Toffola takes care of the feasibility study and the design of water treatment systems, producing the necessary machinery and the most suitable systems for all the various stages, as outlined below.
