What’s new Our “basic” mechanical design has not been changed since 1992: vertical blades connected at the circumference of a horizontal flat plate. However based on many years of experience and testing with cone-shape and rim-blade aerator types the design of Astrumaer has been optimized pointing out following highlights: - Increased open space for blade, creating increased splashing volume (=more contact area between water drops and air) with as result increased oxygenation capacity - Angular displacement of blade, with as result smoother operation and increased oxygenation capacity. - Bevel shaped outside blade, creating a 10% lower tip speed velocity at the underside of the aerator which has a positive effect on mixing and flow propulsion. - Bended top of blade (partially) which guides the splashing of the water to avoid uncontrolled splash pattern and also increases the mechanical strength of blade. - Reduced diameter of horizontal plate which reduces the hydraulically up-trust forces working on gearbox and civil construction. Besides optimizing the shape of aerator impeller the Astrumaer distinguish itself by other suppliers by selecting the most suitable installation looking at project conditions. By using standardized components, such as intermediate shaft, gearbox and electrical motors and adjust aerator impeller to non-standard lay-out the most optimum “aqua-dynamically” solution will be created looking at oxygenation capacity/efficiency and mixing/flow propulsion.

An ATEX inspection is a comprehensive, periodically required inspection of electrical and mechanical components in explosion-hazardous environments in accordance with NEN-EN-IEC 60079-17. InProces Advies conducts the inspection based on all the information you provide, combined with extensive visual inspections and technical tests and measurements at your location. This provides you with the in-depth insight necessary for (maintaining) the explosion safety of your installation. - Detailed (commissioning) inspection - Periodic visual and accurate inspection - Support for continuous inspection (assessment and/or preparation of loop calculations)

We prevent rust in rooms, dry products and can optimize production processes with the right air drying and treatment.

suitable for measuring turbidity and TSS concentrations up to 4,000 NTU or 100,000 mg/l.

Add oxygen to water and create a beautiful fountain image at the same time? Then choose an aeration fountain. An aeration fountain is a pond fountain and aerator in one. In many situations a nice and good solution for ponds and canals in residential areas, on campsites and in other places where aeration and movement is needed with standing water. An aeration fountain is very suitable for use in natural water, because the pumps are highly insensitive to pollution. Pond fountain and aerator Our V-Flow aeration fountain combines aeration with a beautiful fountain image, creates a healthy biological balance, reduces the water temperature and takes up the nutrient medium algae formation away. As a result, an aeration fountain produces beautifully clear water.

MIXERS ensure the flow and movement of standing water in canals, ponds and storage basins and large-scale water projects. By circulating water, a mixer prevents the development of algae and significantly improves water quality. Mixers for large and small water features Our range consists of various mixers that are suitable for canals, ponds, storage basins and large-scale water features. The mixers are designed in a floating and fixed arrangement, whereby the motor cable is available in the desired length. Our mixers ensure a large water displacement. The mixers have an adjustable flow angle and low energy consumption. Our Flow mixer can also serve as ice-free preventer.

A VOLUME AERATOR – the name says it all – ensures an enormous water displacement. This results in degassing and oxygen enrichment in large bodies of water . Temperature reduction of heated water also takes place.

Located in Panningen (Limburg) there is a local Rossi authorized workshop for revision, adjustments and local afterservice.

WTW has a wide range of sensors which has auto cleaning function. So no service needed and high uptime

Control technology So many customers, so many demands and wishes. REMONDIS Smart Infra provides 'standard' control cabinets, but we also build custom ones, fully designed and built based on specific requirements. Thanks to our expert panel construction department, you can rely on the proper and safe construction and operation of the requested control system. REMONDIS Smart Infra's control systems have proven quality and are always built and delivered according to the most current standards in the field of technology, safety and sustainability. Telemetry Current information is indispensable. We implement and manage telemetry systems for structural and efficient management. By monitoring remotely you always have access to information about your installations. This makes it possible to optimize your installations and energy consumption. The system helps you to make your management process as efficient and cost-effective as possible. i-View The real-time management system i-View continuously collects, processes and automatically displays all data that is important to you. Because the system is continuously connected to all installations, you as an administrator are aware of the status of these installations at all times. The i-View data can also be easily accessed via a powerful database link to external data, such as meteorological data from the KNMI or data from other sources that are important for your real-time management system.

The BactoSense is a fully automatic Flow Cytometer for continuous on-line monitoring of the amount of microbial cells in a process. The compact instrument is designed to provide a quick insight into the general microbiological quality of a liquid. Result aer available within 20 minutes. The biological “fingerprint” of a fluid and cell-size ratio (LNA/HNA) provide an instant insight into the biological change. Thresholds can be monitored and alarms generated automatically. Compared to plate counting (HPC), the result is much faster, more realistic and more comparable. A completely sealed cartridge is used. No chemicals and waste handling is required. This guarantees safe operation at all times. Cartridges are available for Total Cell Count (TCC) and Intact Cell Count (ICC). Even with a relatively small number of samples, the BactoSense is cost effective.

The Smart Cleaner is a patented automatic cleaning system for optic sensors. With this cleaning system it is possible to use these sensors in heavily polluted applications and still providing very accurate measurements/data. Our system is extensively tested in very polluted waste water installations with excellent reliable results. Low consumption of cleaning fluids
