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.

Landustrie Weedscreen Cleaner: Effective cleaning for pumping stations and water inlets. A reliable screen cleaner is essential for efficiently removing debris from (sewage) pumping stations, water inlets, and wastewater treatment plants. We supply high-quality screen cleaners for a wide range of applications – durable, quiet in operation, and suitable for both wide and narrow water inlets. Whether you need a chain cleaner or a fully automatic overhead cleaner, we always offer a customized solution. The automatic operation, solid gripper construction, and minimal maintenance requirements make our solutions the ideal choice.

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.

Online monitoring of the TOC content of wastewater gives you a better insight into the pollution load you will be burdening the treatment plant with. This enables you to better control the purification process and adjust it if necessary. The analysis of the waste water also allows you to immediately check for possible leaks in your production process. A sudden increase in the TOC content in your waste water flow often indicates an error in your process.

This floating sensor is an ideal instrument to quickly detect oil leakage into the water. The measurement is based on a high-frequency electromagnetic absorption technique. The water or liquid surface forms the dielectric between the two capacitor poles. The great advantage of this technique is that no false alarms occur and maintenance is nil. This detector is widely used in the following industries: oil, petrochemistry, power generation and distribution, transport, on- and offshore.

Bij het vaststellen van de Legionella bacterie van een (drink) waterleidingsysteem kunnen Legionella veilige douchekoppen tijdelijk als bescherming worden opgehangen. De verschillende type douchekoppen (wand,plafond of met slangaansluiting) zijn voorzien van een uitwisselbare cartridge. In deze cartridges bevinden zich capillaire microfiltratie membranen, die op zeer effectieve manier bacteriën en Legionella uit het water verwijderen. De watertoevoer zal alleen maar verminderen indien het filter verstopt raakt met het residu (restant) van bacteriën. De AS Shower Comfort van Aquafree is gecertificeerd door het Kiwa.

Inexpensive state-of-the-art UV254 absorption photometer. The integrated UV-LED-technology ensures a long product lifetime. Long-lasting and energy-efficient UV-LED technology and a robust design are the core features of LISA UV. Like all TriOS sensors LISA uses the unique nano coated windows combined with compressed air flushing to achieve long operating times without cleaning. The TriOS G2 interface allows quick and easy integration of the sensor into existing process control systems or external data loggers. In addition to the integrated network interface, LISA UV is available with digital or analog output. The sensor can easily be configured through any standard web browser on a PC, tablet or smartphone. The optical path length can be adapted to the application at any time by various lens sockets. An automatic turbidity compensation is carried out by a second measuring channel. Through application-specific correlation LISA UV can be configured for direct output of BODeq, CODeq, TOCeq. A direct output of UVT254 is also possible. LISA – cutting-edge measurement technology at low investment and operating costs.
