Fully demineralized water is the foundation for systems with high durability and flawless surfaces. Our desalination plants and specialized systems for producing deionized water remove unwanted minerals and salts so thoroughly that the result is high-quality process water that leaves no room for limescale or corrosion. This form of water treatment ensures consistent quality, protects your machinery, and simultaneously reduces the load on wastewater treatment systems.
Deionized water leaves no mineral deposits. After the drying process, your workpieces will be completely free of stains and streaks. This guarantees a first-class surface finish and saves you the cost of time-consuming manual post-cleaning or scrap.
Saltwater is the natural enemy of your metal components. By treating water to produce pure process water, you eliminate the cause of pitting and chemical corrosion. You provide long-term protection for your high-quality equipment, preserve its value, and avoid costly unplanned repairs.
Even the thinnest layers of limescale act as insulation and drastically increase your energy consumption. Using deionized water keeps heat exchangers and pipes clean. If you use ultrapure water, your production system will consistently operate at optimal efficiency, which will significantly reduce your energy costs.
The high purity of the water eliminates the need for extensive use of water treatment chemicals. This not only protects the environment and saves you money, but also makes it easier to comply with wastewater discharge limits. You benefit from significantly longer maintenance intervals and a production process that runs smoothly.
Substances such as lime, salts, or particles can jeopardize your processes and result in high follow-up costs due to maintenance and downtime. Targeted water treatment is therefore not a luxury, but a prerequisite for reliable operations. We transform raw water into reliable ultrapure water, thereby protecting your equipment and reducing your wastewater load at the same time.
Every type of water poses specific risks to your equipment. We analyze your water parameters precisely to remove only what is harmful to your systems. This ensures you receive exactly the treatment your process water requires—efficient, safe, and perfectly tailored to the requirements of your wastewater.
To prevent corrosion and staining, we offer integrated systems for full desalination. Our comprehensive solutions often combine a highly efficient reverse osmosis system with downstream mixed-bed ion exchangers to produce excellent ultrapure water. This precise treatment guarantees process water with the lowest possible conductivity and protects your entire infrastructure.
High nitrogen loads require specialized solutions. We integrate high-performance ion-exchange systems into your process chain that specifically remove nitrate and nitrite. Through this controlled treatment, we ensure the quality of your process water and make it easier for you to comply with wastewater discharge limits.
To protect your products from discoloration, we rely on combined processes. Our comprehensive solutions utilize precipitation and flocculation in conjunction with modern lamella clarifiers to reliably remove metals such as copper and nickel. This ensures that the treatment process guarantees clean process water and metal-free wastewater.
When it comes to microbiological purity, we don’t rely on individual solutions, but rather on comprehensive system protection. By using UV systems or dosing systems as part of our water treatment process, we effectively prevent biofilm formation. This ensures the hygiene of your systems and provides biologically stable process water.
To handle complex organic contaminants, we integrate activated carbon filters or nanofiltration systems into our treatment solutions. These stages reliably remove pesticide residues before they contaminate your process water or compromise the quality of your end products and wastewater.
We offer specialized end-to-end solutions for modern contaminants such as PFAS. Following the highly efficient concentration of the molecules, the crucial step involves permanently binding them to activated carbon or special resins. Only this targeted adsorption prevents the formation of a highly contaminated liquid concentrate that is expensive to dispose of. This protects your production, ensures the efficiency of residue disposal, and prevents the release of critical substances into the environment.
Trouble-free operation begins with pre-treatment. Our filtration systems—such as automatic backwash filters and sand filters—form the foundation of our comprehensive solutions. They completely remove particles and microplastics to protect downstream systems used for process water production from wear and Blockages.
Every industry has its own water quality requirements. Our systems are designed to meet precisely these specific parameters and make your process water a key factor in your production success.
Before the actual desalination process begins, all undissolved substances must be removed. Our robust filtration systems reliably remove particles, rust, and microplastics. This first stage of treatment is essential for protecting the sensitive membranes and resins in the downstream systems from mechanical wear and Blockages.
In this stage, the hardness components are exchanged for sodium ions. The use of our water softening systems and ion exchangers softens the water and chemically stabilizes it. This prevents scale formation in your systems and optimizes the performance of the subsequent desalination steps in the production of high-quality process water.
The core of the overall solution: Using state-of-the-art reverse osmosis systems, up to 99% of dissolved salts, heavy metals, and organic residues are removed under high pressure through semipermeable membranes. This efficient form of treatment already produces extremely pure water while simultaneously reducing the salt load in the wastewater to a minimum.
For applications requiring conductivity close to zero, the final treatment step produces ultrapure water. The use of mixed-bed ion exchangers ensures that even the last remaining ions are removed. The result is high-purity deionized water that serves as the ideal process water, meeting even the most demanding requirements in your production.
To meet the specific requirements of the industries mentioned above, we rely on a wide range of processes. Each system is designed to provide the most efficient treatment for your ultrapure water.
Reverse osmosis filters salts and minerals almost completely out of the water at the molecular level. It is the most efficient method for producing high-quality deionized water from raw water.
Fine filters and multimedia filters remove turbidity and particles in the initial stages. This mechanical pretreatment is essential for protecting the sensitive membranes and resins in your systems from contamination.
By adding additives, interfering ions or organic substances are bound and made removable. This reduces the load on the subsequent full desalination process and stabilizes the quality of the process water.
This process uses an electric current to precipitate contaminants without the need for large amounts of chemicals. It is ideal for pre-treating complex wastewater before the water, after the suspended solids have been removed, enters the final reverse osmosis system.

Here you’ll find some questions about water treatment for fully desalinated water using SPALECK water technology. If you still have questions, just write to us.
Deionized water itself is usually harmless, but residual saline water is produced during treatment (e.g. when regenerating resins or as a concentrate in reverse osmosis). Our systems are designed to minimize this contamination of the waste water and ensure that all discharge limits are safely complied with.
The electrical conductivity (measured in µS/cm) is the indicator for the salt content in the water. The lower the value, the purer the water. A low value is crucial for sensitive processes in order to prevent corrosion, deposits or chemical reactions in your systems.
In common parlance, the terms are often used interchangeably. From a technical point of view, however, demineralized water (fully demineralized water) describes the state of maximum freedom from ions. While “distilled water” is obtained by thermal evaporation, the treatment to produce demineralized water in our systems is usually carried out more efficiently by reverse osmosis or ion exchange.
