Mechanical pre-treatment is important to protect subsequent processes against clogging or abrasion. It is a prerequisite for reliable, low-wear and low-maintenance operation of the entire plant.

The retention, washing, transport and initial dewatering of the coarse matter is a crucial first step in primary treatment to ensure that the complex series of physical, chemical and biological processes within the WWTP operate efficiently. Additional washing of coarse retentions is important to reintroduce organics to the biological treatment.

Thanks to our experience, we offer the optimal solution for any mechanical pretreatment problem. We implement our solutions by providing the most reliable, durable and efficient HUBER products.
