The Nijhuis i-DAF system is based on the innovative i-AERATION system which forms fine air bubbles for the separation of particles ensured by to the patented non-clogging depressurization nozzles. Micro air bubbles are dosed in and before the inlet construction of the DAF unit.In the i-AERATION system, a part of the treated water is brought under a pressure of 5 bar, making air dissolves in water. By reducing the pressure down to 1 bar, small air bubbles of 20 to 60 micron are formed, which quickly stick to the impurities in the water and cause a high degree of clarification
Nijhuis has designed the “i-DOSE” system to comply with this real-time control process, significantly reducing wastewater operational costs (e.g.chemicals, aeration,energy). The system also allows facilities to be operated at a maximum performance with reduced operator’s presence due to the intelligent dosing philosophy. As well a sour existing and proven i-DOSE pre-treatment applications, i-DOSE can also be applied within secondary and tertiary treatments.
Principle of i-DOSEThe i-DOSE philosophy is based on analyzing, controlling and dosing the correct amount of utilities (e.g. chemicals) based on the real-time pollution in the wastewater. The Nijhuis i-DOSE consists of a UV-vis spectrometer, control& algorithm, monitoring system and automatic cleaning mechanism.
Nijhuis Ozone Solutions has developed a unique and innovative technology to eliminate legionellafrom open cooling water systems. With the special method of dissolving and injecting ozone into cooling water, completed is infection is achieved.Due to the powerful oxidation of ozone all living organisms are instantly killed and oxidized. This process takes place without the addition of any chemicals. Legionella control with ozone technology is very effective and economical compared to the traditional technologies based on biocides and other chemicals
is a plug & play packaged recovery system to treat spent CIP solutions (i.e. hot soda based). While the CIP agents and heat remains in the recovered stream, the organic fouling,solids and part of the inorganic soluble content will be captured by special membranes and concentrated prior to disposal.
The system can be applied for both caustic, acid and enzymatic CIP solutions. Typical hydraulic recovery of 75 to 90% can be achieved.We offer modular expanded packaged plants with capacities between 0,5 to 10 m3/hr. In order to determine to best economical and sustainable solution, we offer also offer our i-CONSULTl aboratory services to investigate your specific situation.
