Treatment and reuse of industrial process water


Marcegaglia Spa is a leading industrial group in the steel processing sector, with an annual output of 5.3 million tons. One of their 50 manufacturing plants is located at their headquarters in Mantova, Italy, where Euro Mec realized a water treatment plant specifically for the treatment of water used in conjunction with industrial brushes.

The waste water coming off these industrial brushes is full of brush fibres and very fine solid particles which must be removed before the water can be recycled in the washing process. A chemical-physical treatment cycle was adopted for the purification of such water. Clarification requires the help of substances able to form flakes that then easily precipitate and drag down the contaminating substances thus leaving behind clear water.

The waste water treatment plant includes the following stages: fine screening, coagulation, flocculation, clarification with tubular conduit packs, treated water and pumping to return the treated water to the industrial brushes in operation, reuse of the water in other processes and sludge recirculation.

The clarified water is treated and reused in conjunction with the same industrial brushes in the proportion of: 210 m³/hour of recycled and 20 m³/hr reintegrated into the water treatment plant itself.
