The function of drinking water installations must be checked regularly. Water temperatures, for example, must be recorded and documented as part of a hazard analysis at the tapping points. Those responsible in public institutions, hospitals, nursing homes, but also landlords or the housing industry are often faced with a major bureaucratic challenge and a constant need for training for those carrying out the work due to the many guidelines that must be observed.
The new AFRISO TOOLBOX app promises to help here and offers relief for everyday measurement with the smart CAPBs® sensor module FlowTemp® ST as a flow and temperature measuring device. The app for iOs and Android is literally like a toolbox that simplifies the professional execution of many complex measuring or testing tasks in the field of building services installation and makes them possible quickly via smartphone or tablet. For the market launch, the in-apps “Temperature Profile” and “Thermal Disinfection” will be presented, which will enormously facilitate the daily work of hygiene officers, disinfectors, janitors or installers.
Already in the office, in the run-up to the measurement, the corresponding buildings can be created in the app with their rooms, floors, individual water tapping points and additional information. If one is responsible for the management of several buildings or if the measurements are carried out for other companies, this data can also be assigned to the building.
At the location of the measurement, the person performing the measurement then accesses the data directly and is guided through the respective rooms to the water tapping points to be measured in the so-called “measurement with order”. If rooms or measuring points have been forgotten during the pre-configuration, they can be added at any time later. For the actual measuring process, the flow and temperature measuring device FlowTemp® ST is connected directly to the smartphone.
Like all other CAPBs® modular sensor modules, FlowTemp® ST uses the Bluetooth® Smart interface available in smartphones or tablets for this purpose. After successful connection, the recorded measurement data can be transmitted wirelessly and without delay. The app guides the user “step by step” through the measurement and provides precise information on the necessary procedure of the work step – in accordance with the respective current standards and regulations.
Touchless faucet series for washroom environments
Ideal Standard presents its new Sensorflow automatic and touchless faucet series. With their clean and intuitive design, Sensorflow products are suitable for a variety of washroom environments, whether in office buildings, restaurants, educational institutions or other public washrooms.
Installation options are diverse: the non-contact faucet can be mounted on the wall, on the faucet bench of a washbasin, or mounted on a support plate. Thanks to EasyFix technology and the integration of the battery and solenoid valve into the faucet body, installation of the faucet is straightforward and simple. Converting from a traditional single-lever faucet or a faucet with a push-button system to Sensorflow is straightforward.
The faucets are also easy to maintain: access to the faucet body is conveniently possible from above. Cleaning the products is just as quick and uncomplicated as installation and maintenance thanks to the slim, cylindrical design.
The products in the new series are available in both mains-powered and battery-operated versions. The collection additionally includes models where the temperature can be set manually.
Conservation of valuable resources plays a major role in the product design. The system’s integrated safety shut-off stops after 55 seconds at the latest, even if the sensor is tampered with, for example by sticking it shut. This saves water and enables long-term savings compared with traditional faucets.
The product will be available across Europe from February 2021, making it the first in a series of new touchless faucets that Ideal Standard will successively launch.
“At Ideal Standard, the needs of our customers and end users are the linchpin of our product design. We know how important hygiene and efficiency are. With Sensorflow – whether as an extension of traditional faucet models or as a completely new faucet – we are making the installation of touchless faucets even faster and easier. Installation and maintenance are less complicated than ever, and end users can be confident that they are washing their hands even more safely and hygienically.”

Yokogawa Electric Corporation has expanded its range of analyzers in the OpreXTM product family for water treatment plants. With the launch of the new products, the water treatment technologies that already provide high-quality drinking water in Japan will now be available in Southeast Asia, the Middle East, South Korea, Australia and Taiwan. From April 2021, they will be successively launched in North and South America, Europe and China.
Water quality needs to be continuously monitored, and when deficiencies occur, a rapid response is required to ensure a safe drinking water supply. According to World Health Organization (WHO) guidelines, turbidity and chlorine levels must be tested in all drinking water supplies.
Since the launch of the free chlorine analyzer (reagent-free measurement) in 1962 and the turbidity transmitter in 1973, Yokogawa has been a world leader in turbidity and chlorine analyzers and has continuously developed these products to meet the stringent requirements of Japanese water supplies. These products feature self-diagnostic functions that optimize the maintenance of process plants and equipment.
Yokogawa’s analyzers use transmitted light and scattered light measurement methods, which are recognized as the de facto standard by water utilities in Japan and are characterized by their high reliability. Self-diagnostic functions that reliably indicate when maintenance is due and when faults have occurred are provided by both the TB820D turbidity detector and the FC800D and RC800D analyzers. The RC800D also reports when no measuring liquid is present.
In addition, other SENCOM 4.0 sensors can be connected to the FLXA402T liquid analyzer for turbidity and chlorine measurements (pH, conductivity). The values determined can be transmitted wirelessly to a cloud so that they can be monitored from any location. This minimizes the need for on-site operation and maintenance and ensures more efficient operation of plants whose devices are distributed over a large area.
Lower implementation costs by connecting multiple sensors
Unlike similar products currently available on the global market, the product can be operated simultaneously with two turbidity detectors and chlorine sensors. This significantly reduces implementation costs at sites that require the use of multiple sensors.
Maintaining agriculture systems
Efficiency improvement of Spanish irrigation project
During the dry summer season, the increase of the volume of water available to an irrigation channel in Northeast Spain has benefitted local agriculture. With extensive support from Sulzer, the reservoir of San Salvador has been successfully commissioned with energy consumption kept to a minimum.
Maintaining an effective agriculture system is essential to keeping food on the supermarket shelves and this requires an efficient and reliable supply of water. As the demand for this resource increases, so it becomes more important to optimize the storage and delivery of fresh water supplies.
From the outset, the project owners were very clear that operational efficiency was the top priority to ensure that annual running costs were kept to a minimum. The company Sulzer design and engineering entered the competitive tender with a proposal that would later be shown to offer between 15% and 50% improvement, depending on the conditions, on the running costs of a rival bid. This benefit, while appealing, was supplemented by the proposal from Sulzer to work in partnership with the customer and offer its considerable expertise in pumping solutions.
Rather than just delivering a number of pumps that could deliver the necessary water flows, Sulzer prepared a comprehensive solution that included all the control infrastructure as well as all the maintenance equipment. In fact, the design of the final installation would involve siphon-effect discharge pipework that would improve the performance of the pumps by reducing the static head. For this project, the company proposed some of its latest pumps equipped with premium efficiency, IE3, PE7 motors that would make an excellent starting point for an energy efficient installation.
The customer was looking for a partner to help with the design of the pumping system as well as the infrastructure for removing and installing the pumps for maintenance. This needed careful consideration to ensure safe handling of the pumps. Additionally, all the lifting equipment and procedures had to be approved by an independent assessor.
The circular shape of the pumping station building posed many challenges for the designers, not least the lack of space for all the equipment. Sulzer suggested the installation of one pump control center to operate two sets of pumps. This proposal was accepted, saving both space and expense for the project. The pumping station had to be built in two independently operated sections, allowing pump maintenance to be carried out without affecting capacity.
Each set of four pumps is made-up of two different pump models, chosen by the engineers to offer the most efficient pumping solution for every level of water in the reservoir. The pumps are controlled by variable speed drives and this combination allowed Sulzer to create a chart that showed how different combinations and settings of the pump control system would operate depending on the water levels in the reservoir.
The pumping station is designed to maintain a sufficient water level in the distribution channel so that the irrigation system remains operational. However, the water levels in the reservoir can change substantially, especially between the dry and rainy seasons. Establishing the best pump arrangement and pumping regimes would pose a considerable challenge.
The pumps are installed over two levels as well as being split into two independent sections. Each pump was designed with its own siphon effect system at the discharge point that would deliver considerable energy savings over the whole service life of the pump. This was a very important consideration for the customer, and one that would be pivotal in Sulzer winning the contract.
In installations where large electric motors are operating round-the-clock, small improvements in efficiency can make a significant difference in energy costs. When this is combined with optimized valve designs, the addition of the siphon effect and precision control, the overall efficiency is magnified.
