Innovative process for the treatment of industrial effluents

The treatment of industrial effluents poses numerous challenges for businesses, due to the diversity of the types of pollutants generated and the complexity of manufacturing processes.

Each industry — whether food, chemical, paper, paper, textile or metallurgy — produces effluents whose chemical and physical characteristics vary enormously. These effluents often contain suspended matter (MES), organic compounds (COD, BOD5), heavy metals, fats, as well as specific chemical products. Treatment solutions must therefore be able to adapt their effectiveness to the pollutant loads present, while respecting the strict environmental standards imposed by local and international regulations.

Among the major challenges of water treatment for manufacturers, we find:

Management of large volumes of effluents‍

Industries generate large quantities of wastewater, often continuously, which requires technologies capable of treating large flows without interruption or reduction in performance.‍

The complexity of polluting loads‍

Effluents can contain both solid, liquid and gaseous pollutants, making multi-functional solutions necessary to ensure effective separation of fine particles, fats and dissolved gases, while ensuring overall depollution.

High operational costs‍

Standard processes such as filtration membranes or biological treatments often require significant investments in terms of energy, maintenance, and sludge management, while consuming expensive chemical products (coagulants, flocculants). These processes can also generate additional wastes that are difficult to treat.

Environmental requirements‍

Businesses are subject to increasingly stringent environmental regulations, in particular on the quality of waste and the reduction of their ecological impact. It is essential to adopt technologies that limit polluting discharges and minimize the overall environmental footprint.

Reducing global costs‍

Manufacturers are looking for solutions that reduce both sludge treatment and management costs, while optimizing energy and water consumption. This requires technologies that consume little energy and have low maintenance costs.

Faced with these challenges, technology Val de Coldep

is positioned as an innovative and effective response. Based on a process of vertical vacuum flotation, it makes it possible to meet several of the main challenges in the treatment of industrial effluents:

Multifunctional treatment

The VAL column combines particle separation, extraction of dissolved gases (such as CO2, N2, H2S) and hydraulic circulation, making it particularly effective for complex effluents.

Energy efficiency

Operating under vacuum, the technology allows a drastic reduction in energy consumption compared to traditional processes, while optimizing the transfer of gas and the separation of solid materials.‍

Cost reduction

The process is simple to implement, requires little maintenance, and operates with a reduced consumption of consumables (coagulants, flocculants) compared to other technologies such as dissolved air flotation (DAF) or membrane filtration.‍

Low environmental impact

Mainly using physical processes with limited additions of chemical products (which can be biobased), VAL technology makes it possible to limit the production of sludge and polluting by-products, thus contributing to the sustainable management of effluents.

In short, technology Val de Coldep represents a global and innovative solution for manufacturers, making it possible to meet the growing requirements for effluent treatment, while guaranteeing a reduction in operational costs and a minimum environmental impact. It is distinguished by its complementarity with certain standard processes (membrane, UV, ozone...), its simplicity, its energy efficiency, and its ability to treat complex effluents in a sustainable manner.
