Industrial activities have often focused on increasing production capacity while neglecting by-product and waste management.

These industrial activities are frequently located near sea ports or large river networks, where discharged sediment has accumulated on the sea or river bed with a negative impact on navigability and water pollution. Dredging – and subsequent material storage near these areas – is not an optimal solution to the problem. In fact, a more complete approach consists of sediment treatment to remove pollutants and contaminants, while recovering materials, recycling water and treating industrial sludge to reduce its storage footprint.

A very similar situation applies to the management of polluted and contaminated land. In the remediation of these areas, treatment measures (permanent or 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 soil, sediment or sludge with a filter press is the one technology that guarantees the highest recovery of water as well as providing a compact solid material coming from the sludge treatment. The composition of the sludge to be dewatered can vary greatly depending on the origin of the material and therefore the filter press equipment is chosen in such a way to guarantee flexible operation allowing the the use of chemicals to aid filtration.

Diemme® Filtration, has always been attentive to the typical needs of various industry sectors, building reliable, robust, and often modular plants which allows for simplicity of transport and installation which is important when the installation can be temporary.
