FAQ

Local water recovery reduces the wastewater volume sent for disposal by up to 95%. Instead of the entire wastewater stream, only the concentrated residual volume is disposed of. Vacuum distillation achieves recovery rates of 90-95%, and in some cases up to 99%.

Industrial wastewater is classified as waste and requires specialised transport, treatment and storage. Environmental levies, duty of care obligations and energy costs add to this. The larger the wastewater volume, the higher the ongoing disposal costs.

Treated water is reused in the process rather than being discharged. This requires an analysis of wastewater sources, their composition and the site's water demand. The key is selecting a treatment technology that delivers stable water quality.

In most applications, recovery rates range from 90-95%, and up to 99% in suitable cases. The exact figure depends on the wastewater type and treatment technology. The more homogeneous the wastewater, the higher the recovery efficiency.

Water is evaporated under vacuum at reduced temperature, then condensed and recovered as clean water. The contaminants remain as concentrate. The process works even with wastewater of complex composition.

It is suitable for wastewater containing oils, emulsions, salts, heavy metals, surfactants or organic compounds. Typical applications are metalworking, surface finishing, automotive, aerospace, chemicals, pharmaceuticals and cosmetics. The specific suitability is verified through a laboratory analysis of a wastewater sample.

A correctly designed water recovery system does not affect production quality. The recovered water has stable parameters and is suitable for technological processes, rinsing or cooling. The key is choosing a technology that matches the wastewater type.

Established methods include vacuum distillation, membrane filtration, reverse osmosis as well as oil and solid particle separation. The choice depends on wastewater composition and the required water quality. Vacuum distillation is particularly suited to difficult and variable wastewater.

The concentrate contains the separated contaminants in a strongly reduced volume, often just 1-5% of the original wastewater. It is disposed of as liquid waste or, in some cases, recovered further. This lowers disposal costs and simplifies waste management.

It removes oils, emulsions, heavy metals, salts, surfactants and organic compounds with high boiling points. Water and contaminants are separated physically. Even industrial wastewater of difficult composition can be effectively treated this way.

Vacuum distillation works through evaporation and condensation, while membrane filtration relies on physical passage through barriers. With oils, emulsions or high salinity, membranes often clog; distillation operates more stably here. The concentrate can also be concentrated to a higher degree.

For industrial wastewater, often when the water is not to be discharged but reused in the process. Instead of treating the wastewater for discharge, around 95% of the water is recovered and only the concentrate disposed of. A separate treatment plant is then not required.

The payback period is typically 1.5-3 years. It depends on previous disposal costs and the volume of water recovered. Savings come from lower fresh water consumption, reduced disposal and transport costs, and more stable operating costs.

Costs depend on wastewater volume (system capacity), wastewater composition such as oil, salt or metal content, and the required recovery rate. Customer-specific requirements such as automation or integration also play a role.

Yes, leasing is a common financing option. It avoids a large upfront investment; the system is paid for through ongoing instalments, and the savings from water recovery contribute directly to refinancing.

Water recovery substantially reduces the wastewater volume reported under waste duty of care records, as only a small concentrate residue is generated instead of large wastewater volumes. Lower fresh water consumption also supports ESG reporting in the areas of Environmental (resource efficiency), Social (water stewardship) and Governance (regulatory compliance).

No. Modern systems are largely automated and do not require constant supervision. Daily effort is limited to periodic parameter checks and emptying the concentrate. Staff resources remain largely unaffected.

Delivery and commissioning typically take 20-25 weeks from the order date. The exact duration depends on system capacity, configuration and on-site preparations.

The footprint depends on system capacity. The smallest systems start at around 15 m². Larger configurations scale up according to the wastewater volume to be processed.

Yes. Vacuum distillation systems can operate as a standalone module or be integrated directly into existing processes. The design is tailored to the existing production setup.

Yes. Water recovery systems are available from a flow rate of 40 l/h. This makes the technology suitable for small and medium-sized machining operations as well, where it is often economically viable.

Local water recovery means that instead of the entire rinse water, only a concentrated pollutant fraction is disposed of. The recovered water is returned to rinses and processes. Operating costs typically drop by several tens of per cent.

Such wastewater frequently contains metals, salts, surfactants or residues of process chemicals. This requires specialised transport, treatment and waste registration. Costs rise linearly with the wastewater volume.

Yes. Water from intermediate rinses is particularly well suited. After separating the contaminants, 90-95% can be recovered. The water is returned to the same rinses or other auxiliary processes, significantly reducing fresh water consumption.

The recovery rate is typically 90-95%. The greatest potential lies in rinses, cleaning and surface preparation. The remainder forms concentrated waste. Each application is analysed individually beforehand.

Yes, provided that water parameters such as pH and conductivity are maintained. The quality of the recovered water is adapted to each specific process, including anodising. Tests are carried out before implementation.

Typical contaminants are metals, salts, surfactants, residues of process chemicals, and paints or pigments. The exact composition depends on the process, for example electroplating, anodising, phosphating or painting. Each project is preceded by a laboratory analysis.

Yes. Distillation processes separate water and contaminants regardless of metal or salt concentration. Metals and salts remain in the concentrate; the recovered water is free of these contaminants. This applies to typically salt-heavy processes such as anodising or pickling as well.

The treated water is returned to rinses, cleaning or surface preparation. The prerequisite is a technology that delivers stable water quality. Fresh water consumption drops and the wastewater volume is significantly reduced.

Selection begins with an analysis of wastewater composition, volume and the quality requirements for the recovered water. The system is then sized for the specific processes. Tests are conducted prior to implementation to validate the economic and environmental impact.

Water recovery from washing, machining and cooling processes keeps the water in a closed loop. Only concentrate, with up to 95% reduced volume, is sent for disposal. This lowers both disposal costs and fresh water demand.

Typical wastewater streams come from parts cleaning, machining, paint shops and cooling circuits. They contain oils, surfactants, metals and organic compounds. The variable composition requires flexible treatment technologies.

Documented reductions in fresh water consumption and wastewater volume, as well as closed water loops, are recognised. OEM manufacturers increasingly require measures to reduce the water footprint as part of their ESG requirements. Reliable data documentation is essential.

By closing the water loop in washing processes. The treated water is reused, significantly reducing fresh water consumption. Operating costs also become more stable.

Requirements depend on the process (cleaning, cooling, surface preparation). Key parameters are pH, conductivity and COD. The recovery technology is selected so that the respective limits are met.

Yes. A staged rollout starting with the largest wastewater sources is common. The investment can be spread over time, and each stage already delivers measurable savings.

Savings come mainly from reduced disposal costs and lower water consumption. With the large wastewater volumes typical of series production, the economic effect is particularly pronounced. In many cases, the investment pays back within a few years.

Rather than disposing of spent cutting fluid emulsions and wastewater entirely, the contaminants are separated out and the process water is recovered. Only the concentrated residue is sent for disposal. This reduces both costs and waste volume.

Yes, with recovery rates of 90-95%. The process separates oils, additives and metals from the water. The recovered water can be reused in the processes, reducing fresh water consumption and disposal costs.

Yes. Spent cutting fluid emulsions are liquid waste and fall under waste duty of care records. Storage and disposal involve administrative effort. Water recovery reduces both costs and administrative burden.

Through physical processes such as vacuum distillation or phase separation. These effectively separate water and contaminants. The result is clean process water and a concentrated residue for disposal.
