At Kurita, we create shared value with customers and the environment. That’s why we developed our Value+ product portfolio, which aims to enhance productivity while reducing the total cost of operations (TCO) and supporting sustainability goals.
Our range of technologies, products, and services effectively minimizes water, waste, and energy consumption while also lowering carbon emissions.
Microbiology, biofilm, Legionella, Pseudomonas are sources for several problems in water systems and therefore of main concern in the industry. A system not properly controlled can lead to high economic losses and have a direct impact on the health of the population.
Kurita has a long experience in the microbiological control and biofilm in water and paper systems. During the last decades, the Kurita R&D developed a complete biocide product range with a broad efficiency against problems caused by microbial life.
To complete our broad range we developed an in-situ biocide system, controlled and dosed by Kurita´s tailor-made dosing equipment.
Technology Benefits
Fast and easy detectable oxidizing biocide.
Monochloramine will be generated
Decomposes 100% to inorganic compounds
Dilurit® BC S-System has extremely high disinfection rate against
- Any kind of slime-forming microorganism
- Sulfate-reducing bacteria
- Legionella
- Algae
- Yeast
- Mould
- Filamentous bacteria
- Pseudomonas
Kurita’s advanced Dilurit® BC S-System is a mild oxidizer with a broad spectrum of efficacy, a long-lasting effectiveness and a good compatibility with other process chemicals.
Our team of experts have a proven knowledge in solving any microbiology-related problem. In addition, we supply state-of-the-art makeup and dosing equipment as well as on-line monitoring and control technology. All our biocides comply with the EU-Biocides-Regulation.
Optimum required dosage is ensured by just in time reaction with Dilurit® BC S-System. As a result, economical and efficient use of the applied products and a smooth plant operation controlled by a continuous online monitoring system is achieved.
Dilurit® BC S-System Key Advantages
- Outstanding performance in a broad pH range (pH 6 -10) – even under challenging conditions (neg. system ORP, high conductivity).
- State-of-the-art make-up and dosage system: 100 % conversion of the reactive components. No AOX (adsorbable organic halogens) and THM (trihalomethanes) formation.
- A very selective oxidizer; no negative effects on process chemicals.
- Biology does not adapt itself to the biocide. Excellent performance in slime control.
- Significantly reduced operating costs compared to other oxidizing systems.
- Real-time process monitoring via CI- and ORP- measurements.
State of the art dosage system available in 3 different versions:
Kurita has developed 3 different dosing systems to optimize the treatment and to automatize the dosage and control of the product application. Each one of these systems is tailored to be able to treat a different kind of applications.
- Economic: dosing pumps controlled by water counter (fixed ratio)
- Comfort: Via cooling tower controller, pH-controlled, (fixed flow)
- Total Control: “Own” controller, flow-rate via a pump, pH-controlled
