Fraccaroli & Balzan wastewater treatment systems and water recycling plants. Since the 1970’s F&B plants have made it possible to recycle the water used in industrial processes. This water can be reused in a continuous cycle without losses into the environment. The residual mud is dehydrated and can simply be dumped. Wastewater treatment plants are used in many different sectors such as stone processing plants, quarries, rock crushing operations, ceramic industries, and aggregates.
