Industrial activities at various levels over time have often focused on increasing production capacity while neglecting the flip side of the coin, which is by-product and waste management.

These industries are frequently located near ports or large river networks, where discharged sediment has accumulated on the seabed with a consequent impact on navigability and water pollution. Dredging alone -and subsequent storage in the vicinity of these areas- is not an integral solution to the problem. In fact, a complete approach consists of sediment treatment aimed at removing pollutants, recovering materials, recycling water and treating industrial sludge to reduce its storage area.

A very similar situation applies to the management of polluted land. In the remediation of these areas, treatment measures (sometimes permanent, sometimes temporary) are often required to remove pollutants (e.g. heavy metals, hydrocarbons) and to recover materials that can be reused again using wet processes.

Filter press technology

Dewatering with a filter press is the one that guarantees the highest recovery of water and a compact solid coming from the sludge treatment. The composition of the sludge to be dewatered can vary greatly depending on the origin of the material. The equipment is chosen in such a way as to guarantee flexibility in management, sometimes including the use of chemicals to aid filtration.

Diemme® Filtration, which has always been attentive to the typical needs of the various sectors, in these cases builds reliable, robust, often modular plants taking into account -where the installation is temporary- simplicity of transport and installation.
