Physical-chemical treatment

Thanks to their modularity and compact footprint, our prefabricated physical-chemical plants are manufactured using materials compatible with the chemical characteristics of the wastewater to be treated, including stainless steel, polypropylene, and fibreglass reinforced plastic. They can be easily adapted to meet different client requirements.

Our systems

Physicochemical systems are suitable for drinking water treatment, remediation of contaminated groundwater, and the treatment of industrial wastewater and first flush stormwater.

This technology is ideal when biological processes alone are not sufficient to remove substances such as heavy metals, oils, surfactants, or persistent organic compounds. It can also be used as a pre-treatment stage for industrial wastewater and as part of advanced polishing systems.

In addition to conventional treatments, our systems can integrate advanced oxidation processes, such as the Fenton process and ozone oxidation. These technologies enable the breakdown of complex organic compounds and further reduce pollutant loads, improving the quality of treated water.

Typical configuration of a physicochemical treatment plant

Physicochemical treatment systems are sized based on wastewater characteristics and supported by specific jar test trials carried out in our laboratories.

Treatment systems are generally based on a sequence of chemical reactions and physical processes, designed according to the type of pollutants to be removed from the water.

Each system is specifically configured, integrating the necessary sections to ensure maximum treatment efficiency.

The main sections that may form part of a system include:

1Pretreatment

Fine screening, oil removal, grit removal, flotation for the elimination of coarse materials, sand, grease, oils, and other suspended solids.

2Chemical Conditioning Reactors

pH adjustment: regulation of pH levels to optimise subsequent chemical reactions.
Coagulation: addition of reagents that promote the aggregation of colloidal particles into larger flocs.
Flocculation: gentle mixing to allow flocs to grow and become easier to separate.

3Sedimentation and Flotation

Systems for the separation of sludge flocs formed during clarification and flocculation.

4Chemical Oxidation Reactors

Fenton process, ozone oxidation.

5Filtration

Passage through sand filters, activated carbon, adsorbent materials, and selective resins to remove dissolved pollutants and to provide final polishing.

We support clients in selecting the most suitable technology, including the supply of pilot plants to test the most appropriate process scheme prior to the implementation of the final system.

Chemical-physical plant

Chemical‑physical treatment plants make it possible to correct pH and remove heavy metals, oils, hydrocarbons, surfactants and approximately 60–70% of the organic load contained in the wastewater to be treated.

They can also be used as pre‑treatment modules for highly polluted effluents, in combination with biological treatments and/or tertiary systems such as filtration, adsorption, ultrafiltration or reverse osmosis.

Sedimentators

The sedimentation process allows purification sludge to be separated by gravity. The tank configuration promotes the settling of solids on the bottom, where they can be easily removed or recirculated.

We design and supply sedimentation modules with flow rates of up to 100 m³/h.
