Hölscher Solution_#02

WATER TREAT MENT

Our freshwater reserves are increasingly under strain from climate change and pollutants like pharmaceuticals, microplastics, and pesticides. Natural contaminants such as iron also present challenges in many regions. We specialise in reclaiming water and making it usable again.

Recycling Water

Due to the increasing stress on our natural water resources, we at Hölscher have made it our mission to make water removed from the cycle usable again Whether it’s construction water from site dewatering, process water from industry or contaminated groundwater from past pollution, we offer tailor-made solutions for water treatment and re-introduction, thus protecting our most valuable resource in a sustainable way. We use specialised treatment technologies to ensure water quality and purity.

Services and Methods

Construction water treatment: Tailored solutions

Whether it is specialist foundation work, tunnel construction, pipeline installation, or sewer projects, we have 40 years of experience in construction water treatment. We always find a tailored solution for your project. We offer both stationary and temporary systems. Our strengths here lie in treating a wide range of water volumes – be it small amounts or thousands of cubic meters per hour, anything is possible. Comprehensive planning, efficient execution and end-to-end services ensure the economic success of your project. Our systems are controlled and automated using the latest PLC technology. Always in focus: Preventing damage to the environment or nature when water is returned to rivers or aquifers.

Process water treatment: Responsible water use

Water is our most precious resource, and at Hölscher, we do everything we can to use it efficiently and responsibly. Whether for industrial applications or potable water supply, we design and implement tailored systems for process water treatment and reuse. In this way, water from water-intensive manufacturing processes, such as paper production, can be used water multiple times. Our customised planned systems optimise groundwater use for applications like steam generation, cooling water, irrigation, or even drinking water. With our expertise in well drilling, we offer you complete solutions from a single source.

Groundwater remediation: For a cleaner future

With decades of expertise in groundwater and soil vapour remediation, as well as contaminated soil reclamation, we are your reliable partner for demanding legacy pollution projects. Hölscher delivers customised solutions to tackle contamination challenges efficiently and sustainably. From initial consultation to final implementation, we create remediation concepts that meet your exact needs – quickly, cost effectively and environmentally conscious. Our modular system designs offer maximum flexibility and seamlessly adapt to the unique requirements of each project. Automated processes and state-of-the-art remote monitoring ensure the highest levels of efficiency and safety at all times.

Precipitation, flocculation, and filtration systems

Precipitation, flocculation, and filtration systems are water treatment systems that remove unwanted substances from water through chemical reactions and physical processes. Initially, contaminants are bound through precipitation and flocculation and subsequently filtered out of the water by filtration.

Sedimentation systems

Sedimentation systems are water treatment devices that use natural gravity to retain suspended solids. They are used to improve water quality and reduce environmental impact.

Ion exchange systems

Ion exchange systems are water treatment systems that replace undesirable ions in water with desirable ions to improve water quality. They are used, for example, for water softening and the removal of heavy metals.

Iron and manganese removal systems

Iron and manganese removal systems effectively remove iron and manganese from water. This reduces deposits or enables re-injection. Our systems ensure high water quality and protect technical installations from corrosion and damage. Depending on requirements, the systems can be individually adapted to handle different water loads.

Stripping systems

Stripping efficiently removes pollutants from water by driving them out through air contact. In special packed columns or horizontal stripping systems, water is intensively mixed with air, causing pollutants to transfer into the air. Depending on the required purification level, these systems can operate in single or multi-stage configurations or in series to achieve optimal results.

Activated carbon filter systems

Activated carbon filter systems are water purification systems that remove pollutants, odours, and chemicals by adsorption on the porous surface of activated carbon. These systems are used to improve water quality.

Sludge treatment and conditioning systems

Sludge treatment and conditioning systems are essential for the efficient processing and disposal of wastewater and industrial waste by dewatering and reducing the volume of sludge. Through processes such as thickening, stabilisation and drying, sludge is treated to minimise environmental impact and conserve resources.

Neutralisation systems

Neutralisation systems are systems for treating acidic or basic waste water in which chemical reactions adjust the pH to a neutral level.
