The right wastewater treatment often raises many questions – from legal requirements to technical solutions. Here you will find concise answers to the most important questions about the efficient and safe operation of your system.
Which LK Metall products are suitable for which type of wastewater?
Pre-treatment: Light liquid separator, sludge trap, tangential separator
Process wastewater: Light liquid separator, filtration, tangential separator
Industrial and workshop wastewater: Light liquid separator, sludge trap, filtration, tangential separator, chemical-physical systems
Media/circulation management: Light liquid separator, filtration, tangential separator
Petrochemical industrial wastewater: Light liquid separator, sludge trap, filtration, chemical-physical systems
Degreasing/galvanizing: Light liquid separator, sludge trap, filtration, chemical-physical systems
Why is professional wastewater treatment necessary?
Professional wastewater treatment ensures that legal limits are adhered to and that no environmentally harmful substances enter the wastewater system. It also protects systems and pipes from deposits or corrosion and can treat water for reuse, which saves costs and conserves resources.
What legal requirements do I have to observe for wastewater treatment?
In Germany, the Wastewater Ordinance (AbwV) regulates the permissible limit values for pollutants in wastewater. In addition, companies must comply with the Water Resources Act (WHG) §62 AwSV if they work with substances hazardous to water LK Metall is a certified WHG specialist company.
Depending on the industry and location, further local regulations may apply.
Which industries require special wastewater treatment?
Industries such as the food and beverage industry, metal processing, chemical and pharmaceutical industry, textile production as well as the automotive and plastics industry require special wastewater treatment systems. Tailor-made solutions are required, especially when contaminated process or production water is produced.
How can I reduce operating costs through optimized wastewater treatment?
By using modern technologies, contaminated water can be treated more efficiently and in some cases reused. Automated monitoring systems reduce plant maintenance costs and prevent unplanned downtime. In addition, the right chemical or biological treatment helps to reduce expensive disposal costs.
How long does it take to install a wastewater treatment system?
The installation time depends on the size of the system and the individual requirements. Smaller systems can be up and running within a few days, while complex, customized solutions can take several weeks. With our experience and detailed planning, we ensure that everything runs as quickly and smoothly as possible.
How long is the service life of a wastewater treatment plant?
The service life depends on the quality of the components, regular maintenance and the operating conditions. High-quality systems can easily remain in use for 15 to 25 years or longer. Regular inspections and the timely replacement of wearing parts extend the service life considerably.
What are the benefits of efficient wastewater treatment for my company?
Optimized wastewater treatment reduces operating costs through lower fresh water consumption and lower disposal costs. It also protects the environment and health, minimizes liability risks and ensures compliance with legal requirements. Companies with sustainable water treatment also benefit from a better image and possible subsidies.
