professional laundres

They are obliged to treat process water and to comply with the limits imposed by current legislation before discharging waste water to the final discharge. The latter is even more relevant when the final receiving body is not a public sewer but a surface water body. Why is a laundry required to treat its process water before discharging it? To get an idea of the composition of laundry water, one only has to think of the waste water from domestic washing in our homes. Someone is wondering then why we are not required to treat our domestic waste water. Well, the answer is simple and lies in the fact that domestic water is more diluted than water from an industrial process and therefore easier to purify in a municipal purification plant.

In the professional field, we find various types of laundries; these differ in the complexity of the process adopted. In fact, the quantity and characterisation of the effluent produced depend essentially on the type of machines (washing machines) used and the sector served: hotels, restaurants, canteens, hospitals, retirement homes, etc. Wastewater from washing essentially contains substances removed from fabrics (organic material) together with chemicals (detergents, softeners, surfactants) and fabric residues. Compared to the past, biodegradable products are now used and synthetic detergents are banned. This has enabled the increasingly widespread use of biological treatment with activated sludge instead of chemical-physical treatment. However, the choice of the most suitable type of treatment strongly depends on the characterisation of the effluent, the size of the user and the limitations imposed on the final discharge.
