Die casting

Wastewater from die casting (oily emulsions, release agents, lubricants, mold washings, water, and glycol) is characterized by a high production of wastewaters.

Problem:

The wastewater produced by die casting primarily consists of oily emulsions, additives, release agents, surfactants, lubricants, silicone compounds, mold washings, glycols, and natural or synthetic waxes.

Water is also used for cooling oils, molds, and the produced casts, and for mixing the release agent.

All these wastewaters have a high-water content but are often difficult to purify. Available market options do not offer appreciable results and lead to costly disposal phases.

Solution:

The most efficient solution is to recover the water present by separating it from the various organic pollutants: the technology of evaporation is the most effective treatment process, achieving a clear separation between water and pollutants without the use of chemicals.

Advantages:

→ Drastic reduction in disposal costs
→ Water consumption savings
→ Zero discharge
→ Recovery of a good portion of water volumes
