Industrial sludge treatment: challenges and benefits

The treatment of industrial sludge is a crucial process for both public health and environmental protection, encompassing several techniques for purifying and recovering this material. Industrial sludge, which is the solid residue from wastewater treatment in industry, is treated to render it inert, dry it out and eventually recover it as a source of energy or material.

Sludge types and treatment options

Different types of sludge can be produced in an industrial water treatment process. Primary and tertiary sludge are specific to the type of industry and the contaminants present in the effluent, and therefore to the treatment used (physico-chemical, etc.). Biological sludge is produced at the biological treatment stage, where applicable, and can be recovered as energy or material.

The choice of the type of treatment to be applied depends on the nature of the sludge and the regulatory constraints in force. The quality of the sludge depends on the pollutants initially present in the effluent and the treatments carried out. This quality will have a major impact on the performance of the sludge dewatering solution, in particular depending on whether the sludge is hydrophobic or hydrophilic (biological sludge or rather primary or mineral sludge, etc.). The quantities of sludge matter to be treated (TSS) also influence the solution to be implemented. Finally, the sludge’s possible recovery or disposal channels define the intensity of treatment to be implemented (hygienization or stabilization required, minimum dryness, etc.).

Treatment methods

The main treatment methods involve initial thickening to reduce the volume of water in the sludge and obtain a more fluid sludge. This is followed by dewatering, which modifies the structure and physical state of the sludge by increasing its dryness, transforming it from a liquid to a pasty or solid state. Dewatering is often preceded by a sludge conditioning stage involving the addition of polymers. This operation ensures good separation of the water from the material.

Depending on regulatory or operational requirements, dewatered sludge may undergo additional stabilization (to reduce biodegradability and odors) or hygienization stages before it can be reused. Finally, the final stage may involve drying, incineration, composting or landfill disposal. Each of these techniques requires specific equipment such as filter presses, screw presses, centrifuges, clarifiers, dryers or incinerators.

Benefits of industrial sludge treatment

Implementing effective industrial sludge management has a number of benefits:

Regulatory compliance: sludge treatment is often a legal requirement, particularly for companies producing large quantities of waste or effluent.
Environmental protection: treatment minimizes the impact of sludge on the environment by limiting pollutant discharges into the natural environment and promoting waste recovery. The water recovered from sludge treatment can also be put to new uses in the process, and treated sludge can potentially be used in the production of agricultural fertilizers.
Reduced health risks: treatment eliminates pathogens and organic or chemical pollutants potentially harmful to human health.
Economic value: sludge treatment reduces the volume of sludge, and therefore the costs associated with its outsourcing or subsequent recovery. Sludge can also be used as a source of energy (biogas) or recyclable materials.

Adopting an industrial sludge treatment system is a virtuous process for the company, combining compliance with legal obligations, environmental protection, public health protection and optimization of resources.

Industrial sludge treatment, an industrial tool for transformation

Sludge thickening and dewatering is a crucial step in wastewater treatment. By considerably reducing the volume of sludge, this process minimizes effluent transport, disposal, storage and drying costs.

Robust, proven technologies

Ovive offers a complete range of robust, proven technologies to meet all your sludge treatment needs. Our solutions enable efficient separation of liquid phases and produce a high dry matter content. Treated sludge can then be recycled as digester feedstock for biogas production, thermal treatment and composting.

Solutions tailored to your needs

Ovive offers a range of sludge dewatering technologies to meet your specific needs. We’ll work with you to determine the technology that’s best for you, based on the desired dry solids content, available space and other requirements: K-BOX, filter press, decanter, centrifuge, screw press, reed bed…

Vision of a sustainable industry

Ovive’s vision is that of a sustainable industry, where sludge treatment is not just a regulatory constraint, but also an opportunity to improve industrial processes. By offering a wide range of sludge treatment solutions, Ovive enables companies to move towards a circular economy, where every waste product becomes a resource.

Optimization and valorization

By optimizing energy consumption and reducing waste, industrial sludge treatment can help increase the efficiency of production processes while respecting the environment. What’s more, by recovering the organic and chemical materials contained in sludge, industries can reduce their operating costs, while recovering waste. The water recovered in the sludge treatment process can also be reused in processes.

Partnership for sustainable transformation

With Ovive as a partner, industrial sludge treatment becomes not only a response to an environmental requirement, but also an opportunity for sustainable, efficient and environmentally-friendly industrial transformation.
