With a polder pumping station, which can be a pump or screw pump, we ensure that water levels in a specific area are regulated. A pumping station pumps water from a lower or higher level to a lower level. For new construction or renovation of a pumping station, we offer a complete solution: we design, build, and install all the necessary components.

The construction of sewage pumping stations is a specialized field. We have experience in designing, building, and renovating various types of sewage pumping stations, including dry and wet pumping stations and booster pumping stations. When renovating an existing pumping station, we provide a temporary pumping system that takes over the pumping station's work, ensuring that the surrounding area—both people and nature—is not impacted by our work.

Glasvrij en onbreekbaar ISFET pH-sensoren kunnen worden gebruikt in alle toepassingen waar pH-glas sensoren niet geschikt zijn vanwege uitdagende procesomstandigheden of het risico op breuk. Het gebruik van glassensoren wordt vooral in toepassingen in de voedings- en drankenindustrie en de life sciences industrie vermeden, omdat hele productiepartijen bij glasbreuk besmet kunnen raken. De ISFET-sensoren van onbreekbaar PEEK zijn verkrijgbaar met drie verschillende referentiesystemen, wat betekent dat er een glasvrije sensor is voor elke behoefte. Gecertificeerd hygiënisch ontwerp De nieuwe ISFET-sensoren Memosens CPS47D en CPS77D van Endress+Hauser zijn speciaal uitgerust om te voldoen aan de strenge eisen van hygiënische toepassingen. Dankzij hun nieuwe ontwerp met een groter chipoppervlak zijn ze nog gemakkelijker te reinigen dan hun voorgangers. Ze leveren stabiele en reproduceerbare meetwaarden, zelfs na sterilisatie en autoclaveren tot 135°C, zijn voorzien van alle gebruikelijke hygiënegoedkeuringen voor de voedings- en life sciences industrie, zoals USP, EHEDG en 3A, en zijn TSE-/BSE-vrij. Ze kunnen minstens 25 CIP-cycli overleven en hebben daardoor de CIP-stabiliteit aanzienlijk verbeterd in vergelijking met conventionele ISFET-sensoren. Bovendien biedt de Memosens CPS77D maximale bacteriedichtheid dankzij het microporeus keramisch membraan. Snelle reactietijd, zelfs bij lage temperaturen Chemische processen bij lage temperaturen en met een hoog gehalte aan organische oplosmiddelen of vaste stoffen vormen specifieke uitdagingen voor pH-metingen. Zelfs bij lage temperaturen hebben ISFET-sensoren zoals de Memosens CPS97D een snelle reactietijd en zijn ze chemisch stabiel dankzij hun PEEK-schacht. Ook betekent hun open diafragma dat ze niet verstopt raken, zelfs niet in het geval van hoge concentraties vaste stoffen. De stevige gel die in de referentie wordt gebruikt, is ook zeer goed bestand tegen chemicaliën.

This results in high-quality effluents suitable for reuse, drinking water production, or safe discharge. All systems are designed with a focus on sustainable performance: low energy consumption, minimal chemicals, compact design, and expandability for future capacity requirements. Thanks to in-house skid production and high-quality Dutch engineering, the installations meet the strictest industry standards, with optional drinking water certification. NMS supports companies on their journey to circular water management, zero liquid discharge, and cost-efficient water management – ​​with reliable, flexible, and fully integrated membrane solutions.

Micropollutants are persistent contaminants originating from everyday activities, posing a serious risk to water quality. Treating wastewater contaminated with these substances is highly complex, and there is no universal solution. Achieving effective removal requires a customized combination of technologies, carefully aligned with the specific characteristics of the wastewater and local regulatory requirements. Nijhuis Saur Industries has developed the MicroOxi solution to support WWTPs in addressing micropollutant challenges with sustainable, client-focused approaches. Depending on the local context, we apply an optimized mix of oxidation technologies, including BODAC. Our method is designed to minimize both total cost of ownership and environmental impact. With our extensive portfolio of micropollutant-removal technologies, we ensure the selection of the most suitable solution to meet your removal targets and resilience requirements.

Bypass Absorptionmeter Nitrate Nitrates are nitrogen compounds that occur naturally in the soil, but also enter the soil as a component of fertilizers. Even a small amount of nitrate in drinking water can pose a health risk! Sigrist ColorPlus 3 offers you online measurement of nitrate. As a light source, a long-lived xenon flash lamp is used having a very low loss of intensity over a long time! The medium is measured with two optical path lengths from which any soiling is determined. The value measured is automatically corrected and the instrument informs the user when the measuring cell has to be cleaned. The PVC cover can be removed without tools. Free access to the optics allows simple cleaning of the measuring cell. The instrument indicates any maintenance due. The control unit SICON selectively displays values, graphs, status and alarms on state-of-the-art touchscreen technology and colour display. Internal data storage allows the visualization of the measurements over the last 32 days. The instrument is used in the treatment of drinking water. Features Uniform, precise measurement Simple, tool-free maintenance. Compensation of window soiling Service life of light source: 10 years

The SetLR-Monitrix is specifically designed to overcome solids problems when measuring in the aeration tank of a WWTP. The SetLR-Monitrix is equipped with a NOx monitrix analyser in a heated cabinet suitable for outdoor installations*. The SetLR-Monitrix works on the basis of sample settling instead of filtration, which avoids problems such as biofilm build-up and interference on measurements. The SetLR system is robust, and easy to operate and maintain. The SetLR collects a sample of approximately 4 litres from the aeration tank into a settling tank. The supernatant is transferred to the sample chamber where vacuum and compressed air are used to collect a 50ml sample suitable for analysis.

Nitrogen emitted by installations, processes, and machinery deposits on soil, water, and nature, potentially causing damage in vulnerable areas. The AERIUS calculation method calculates how much nitrogen a project emits and where it deposits, as mandated by the government. InProces Advies performs a complete AERIUS calculation using the official calculation module, performing a detailed analysis of the entire project. This clarifies whether nitrogen deposition occurs on Natura 2000 areas and whether a permit is required. The calculation shows the project's contribution to nitrogen pressure and provides insight into potential measures to reduce it.

The NivuFlow Mobile 750 flow meter is a portable device that performs highly accurate flow measurements in partially filled and full pipes and open channels. It uses up to 3 ultrasonic v-sensors and is based on the cross-correlation technology for flow profile detection. In terms of operation, you can intuitively configure the relevant parameter settings via a web browser on mobile devices such as tablets and smartphones using a quick start assistant. In addition, the NivuFlow Mobile 750 has an optional built-in modem that allows automatic data transfer via email, FTP or a web portal. This means that service employees do not have to read the device on site. You can also set alerts for specific events, such as error messages. The battery has a long lifespan, which means maintenance requirements are minimal. This versatile device can be used on both clean and polluted water. In short, the NivuFlow Mobile 750 is a useful solution for accurate flow measurements in different circumstances. Besides this flow meter, we have other flow meters from Nivus.
