Reduce wastewater costs - Conserve resources
Close the water loop in your production process. With modular SPALECK technology, you can reduce your fresh water consumption and minimize your environmental footprint—efficiently, safely, and with high efficiency.
Instead of raw water of varying quality, the treatment process delivers water with precisely defined parameters. This prevents limescale buildup, corrosion, and biofouling in your machinery, extends maintenance intervals, and ensures consistent product quality.
Modern water treatment plants help you meet internal and regulatory water quality requirements. This simplifies the permitting process for facilities and ensures long-term operating authorization in the face of increasingly stringent environmental regulations.
Every industrial process is unique and requires a detailed analysis of the material loads involved. Whether it’s specialized chemicals, complex organic compounds, or industry-specific byproducts—we analyze your water samples in our in-house laboratory. Based on this data, we develop the technically and efficiently optimal treatment strategy, tailored precisely to your operations.
In closed-loop systems, particles such as sand, metal abrasion, or fibers accumulate quickly. Without mechanical removal, these substances act like sandpaper on pumps and seals or cause blockages in fine spray nozzles. Our water treatment systems reliably remove these solids via a bypass stream to preserve the mechanical integrity of your entire site infrastructure.
Cooling lubricants and cleaning baths tend to emulsify in the circulation system. This leads to unwanted deposits on workpieces and sticking of downstream filter units. Using targeted physicochemical processes or ceramic ultrafiltration, we separate these phases, maintain the surface activity of the circulating water, and prevent the gradual deterioration of your process results.
Warm circulating water promotes the growth of biofilms in tanks and pipes. These deposits not only reduce flow rates but can also cause pitting corrosion on stainless steel components. For example, we integrate disinfection stages into the circulation system to ensure hygienically safe water quality and guarantee workplace safety at open process tanks.
Dissolved organic substances such as sugar, starch, or alcohols provide an ideal breeding ground for microorganisms. Without proper control, the cycle “goes haywire”: unpleasant odors and aggressive organic acids develop. Our water treatment systems reduce this biological load (e.g., anaerobically), recover valuable energy from it, and ensure odor-free, biologically stable recirculating water.
In closed systems, evaporation and continuous recirculation cause the concentration of dissolved salts to increase. This leads to massive scale buildup in pipes and promotes corrosion on metal surfaces and seals. Through the targeted use of membrane technology or ion exchange, we maintain conductivity and hardness levels precisely within the target range. This helps you avoid costly repairs and ensures the long-term functionality of your entire process technology.
This modern water treatment process offers a cost-effective solution for safely keeping used water in the cycle. We’ll work with you to determine whether your specific constituents and process parameters are ideally suited for full recycling through a thorough initial analysis. The system reliably reduces disruptive contaminants, ensures your production quality, and sustainably lowers your operating costs by minimizing fresh water consumption.
To successfully recycle water and minimize the impact on wastewater, we rely on a wide range of physical, chemical, and biological processes.
Filtration is the first step in protecting your equipment. Sand, multi-media, or cartridge filters are used to efficiently remove solids and microplastics. This ensures particle-free process water, which reliably prevents blockages in nozzles and pipes.
Using ultra-, nano-, or reverse osmosis membranes, we reliably remove dissolved substances and minute impurities. This stage is crucial for producing high-quality deionized water and makes it possible to treat even heavily contaminated water for demanding processes.
An electric current releases ions that bind to and precipitate contaminants. This process reduces the use of chemicals in wastewater treatment and is particularly effective in treating complex emulsions or wastewater containing heavy metals.
This stage efficiently breaks down high levels of organic matter and significantly reduces the amount of sludge. Our plants use this process to achieve high levels of efficiency in preparing contaminated water for further treatment or recycling.
Through targeted oxygenation, microorganisms thoroughly break down residual substances in the process water. The result is high-quality water that can be safely reused or discharged as wastewater.
Targeted active ingredients bind dissolved substances, such as metals, and convert them into filterable flocs. This stage is essential for drastically reducing the pollutant load within the systems and stabilizing water quality.
We start right where the wastewater is generated. By treating sub-streams—for example, directly at a washing station or cooling line—we maintain a consistently high level of water quality in that area. This minimizes pipeline lengths, saves energy, and prevents the wastewater from burdening the rest of the plant’s network.
In this phase of the project, we consolidate various wastewater streams into a single central water treatment unit. The treated water is then distributed according to the cascade principle: ultra-pure water for production, moderately treated water for cooling processes or facility cleaning. This allows you to reduce your fresh water consumption to an absolute minimum.
For wastewater with high organic loads, we integrate an anaerobic treatment stage, for example. This not only treats the water for reuse but also produces biogas. You generate valuable energy for your facility and turn disposal costs into a measurable return on investment.
The recycling of process water requires precise, step-by-step treatment. Our systems specifically remove contaminants and convert contaminated wastewater streams into a valuable resource—ensuring consistent quality at minimal operating costs.
In the first step, all settleable solids and coarse particles are removed from the wastewater. By using compact lamella clarifiers or filtration, we immediately reduce turbidity. This stage is crucial for preventing wear on pumps and piping and for protecting the downstream, finer treatment stages from overload.
The primary treatment process addresses the specific contaminants that prevent direct reuse. Depending on the requirements, anaerobic reactors are used for the biological degradation of organic loads (COD/BOD), or the RedBox is used for the chemical-free breakdown of oils and greases. The goal is a biologically and chemically stable aquatic environment.
In the final step, the water is brought to the exact target quality required. Membrane systems (ultrafiltration/reverse osmosis) or ion exchange are used to remove the finest particles, bacteria, and dissolved salts. The result is high-quality process water or deionized water that can remain in the cycle indefinitely without any loss of quality.
