Zoals aangegeven in de verordening van oppervlaktewater (Rijkswaterstaat), dient het te lozen effluent water gemeten te worden. De kwantiteit wordt onder andere door een flowmeter of meetgoot gemeten. Het is een vereiste elk jaar een droge “kalibratie” uit te voeren en elke 5 jaar een natte kalibratie uit te voeren. Deze natte kalibratie maakt het voor de gebruiker vaak lastig, omdat de meetbuis eruit moet om vervolgens op een ijkcircuit gekalibreerd te kunnen worden. Dit brengt hoge kosten met zich mee; zeker als het grote diameters betreft en als ze ondergronds zijn ingebouwd. KROHNE heeft samen met Rijkswaterstaat een goedgekeurd protocol opgesteld, dat tijd en kostenbesparend is. Hiervoor wordt een OPTISONIC 3400 in-line ultrasone flowmeter gebruikt, beschikbaar in DN25 – DN3000 en optioneel in ondergrondse uitvoering (IP69/ NEMA 6P). Doordat er gebruik wordt gemaakt van een mastermeter zijn alle gegevens van de elektronica beschikbaar. Ten tijde van een natte kalibratie hoeft alleen de elektronica te worden toegestuurd en kan de meetbuis ingebouwd blijven. Daarnaast wordt de meting in bedrijf jaarlijks gecontroleerd en kan bovendien via de ultrasone meettechniek de mate van vervuiling in de meetbuis geconstateerd worden. Dit alles maakt het voor de gebruiker een stuk eenvoudiger om aan de richtlijnen van Rijkswaterstaat te voldoen. Inmiddels zijn al een aantal afvalwaterzuiveringen voorzien van deze meter, en is men enthousiast over deze kostenefficiënte oplossing. Bent u geïnteresseerd in of heeft u vragen over deze oplossing? Wij komen dit graag binnen uw organisatie toelichten.

Custom-made screw pumps for reliable water transport! Looking for a robust solution for pumping large volumes of water? The Landustrie screw pump offers the solution. For over a century, we have been producing screw pumps – also known as Archimedes screws – for applications in pumping stations, wastewater treatment plants (WWTPs), irrigation projects, and flood management. Each screw pump is custom-designed and manufactured in our own factory in Sneek. Thanks to their open design, low energy consumption, and maintenance-friendly construction, our screw pumps have an exceptionally long service life, even under the toughest conditions. The Landustrie screw pump functions as a positive displacement pump based on the principle of Archimedes screw. At the inlet point, water flows into compartments between the blades. The rotating motion and the angled design gradually move the water upward. This open and clog-free design allows us to pump large volumes of water at a relatively low speed – without the risk of clogging or damage. This makes the auger extremely suitable for continuous use, even in water that is polluted or contains coarse particles.

For wastewater treatment, we design and supply a wide range of LANDY pumps. These pumps are designed and manufactured in-house at our Sneek facility. The pump range includes both submersible and dry-installed pumps and mixers. We offer a variety of materials, including cast iron, Duplex, and Nihard, a wear-resistant material. We are happy to work with you to select the optimal pump for your specific application. This can include the corresponding control system and telemetry. We also offer a service department that can respond immediately in the event of malfunctions or emergencies. Rental pumps are also readily available.

Landustrie surface aerators provide high oxygen input with consistently high efficiency. Landustrie surface aerators offer a reliable, energy-efficient solution for aerobic wastewater treatment. With a high and consistent oxygen input, low maintenance costs, and a long service life (up to 30 years), they are a solid choice for both industrial and municipal wastewater treatment plants. For situations where temporary aeration is required—for example, during maintenance, emergency solutions, or temporary capacity expansion—we offer the option of renting a floating aerator. A surface aerator—also called a point aerator—introduces oxygen into the wastewater, an essential component of the aerobic treatment process. Our aerators combine optimal oxygen input with sufficient mixing and propulsion of the wastewater. The aerator's unique design ensures even oxygen distribution and prevents sedimentation and dead zones. This keeps the aeration process efficient and stable. We have our own full-scale test tank in Sneek. This allows us to perform oxygen measurements as well as vibration and noise measurements.

With more than 10 trillion liters of process water used annually in Dutch industry, it is important to safeguard the quality of water and prevent pollution. One of the most important parameters to measure the degree of pollution is TOC (Total Organic Carbon). As the name suggests, a TOC analyser measures the total content of organic carbon compounds for both process water and return condensate. Other parameters such as total carbon (TC), total inorganic carbon compounds (TIC) and total nitrogen (TNb) can also be analysed. The online TOC analyser is an accurate measurement method to monitor and control wastewater during your production processes. The control of the process water and/or return condensate is realized by means of a high temperature oxidation (1200 °C) in which the sample is completely converted into CO2 and water, among other things. The formed CO2 is measured in a NDIR detector after treatment. Checking the quality of Purified water and Water For Injection (WFI) are also possible.
