Large-scale implementation of vegetable production with water reuse

The process of an agricultural food production with recycled water, successfully developed in the HypoWave research project, is going into large-scale application for the first time. In the course of the follow-up project HypoWave+, the research network has begun preparations for hydroponic vegetable production with recycled irrigation water on a one-hectare site.

Agricultural production worldwide is increasingly dependent on irrigation. But regional water shortages and the resulting conflicts over use are on the rise. High-yield harvests cannot be taken for granted in Germany either due to prolonged heat and dry soils. New, water-saving cultivation methods are being sought. With the HypoWave+ research project led by the Technical University of Braunschweig, the German Federal Ministry of Education and Research (BMBF) is therefore funding the implementation of an alternative form of agricultural cultivation in combination with water reuse on an industrial scale.

HypoWave process: Alternative for agriculture

The hydroponic process, in which plants in containers without soil are supplied via a nutrient solution using recycled water, had been successfully tested in a previous project in Hattorf, Lower Saxony. “Now the aim is to take the experience gained with the water-efficient process based on recycled water to large-scale production and provide scientific support,” says project manager Thomas Dockhorn of the Technical University of Braunschweig. The new HypoWave process not only offers an alternative to irrigation with drinking water and groundwater. The cultivation method also optimizes nutrient supply, since vital nutrients such as nitrogen and phosphorus are supplied to the plants from the treated water.

Despite water shortages: regional food production in times of climate change

Together with farmers from Lower Saxony, the scientists are planning to produce up to 700 tons of tomatoes and peppers under glass on one hectare of cultivation area. The vegetables will be sold in regional grocery stores throughout the year, except for a short winter break.

“In the course of the scientific monitoring of HypoWave+, we are focusing on questions of quality management and the marketability of the process. We want to set the necessary course for this.”

Advanced analog IC foundry process technologies

Published

on

Now, Siemens Digital Industries Software announced that its new mPowerâ„¢ solution for power integrity analysis of analog, digital and mixed-signal integrated circuit (IC) designs has now been certified for Tower Semiconductor’s SBC13 and SBC18 process technologies.

This software is the industry’s first IC power integrity verification solution that offers virtually unlimited scalability for analog, digital and mixed-signal ICs and provides comprehensive power, electromigration (EM) and voltage drop (IR) analysis for even the largest IC designs.

“Siemens is proud that Tower Semiconductor, an industry leader in analog technologies, has now certified mPower for the SBC13 and SBC18 processes it offers. This solution, developed collaboratively by Tower Semiconductor and Siemens, contributes to more accurate and faster EM/IR analysis for joint customers. This, in turn, results in shorter time-to-market and higher quality end devices.”

– Joseph Davis, Senior Director

With this technology, IC designers can more quickly and thoroughly verify that their analog and mixed-signal designs meet performance-based design goals – capabilities that help IC customers dramatically improve quality, increase reliability and shorten time-to-market.

Novelties in relation to tank cleaning

Published

on

With the PlusClean tank cleaning nozzle, Alfa Laval sets a new standard for hygienic fluid handling in the food, dairy, beverage, pharmaceutical and personal care industries. Users achieve 100 percent cleaning coverage, which is unique in the market. In addition, up to 80 percent water and detergent savings can be achieved compared to conventional methods.

The cleaning nozzle works in tandem with primary tank cleaning equipment such as rotating spray balls or jet cleaners. Depending on the design of the tank, the nozzle can be easily integrated flush into the wall or floor. When activated by the cleaning medium or, optionally, the air drive, it removes contaminants below the agitator blades and in other areas in a fan-shaped pattern.

Controlled and repeated rotation of the agitator shaft and blades ensures 100 percent cleaning coverage. Even the shadow areas below the agitator blades, heating or cooling coils and connections, which are inaccessible to top-mounted tank cleaning equipment, are reliably hit. When the cleaning cycle is complete, the integrated drive returns the piston to its original position, securely closing and sealing the cleaning device.

Contamination risks are minimized by thorough tank cleaning with PlusClean. Faster and safer changeovers increase the productivity of batches or continuous processes.

On the way in the UNESCO World Heritage Wadden Sea

Published

on

In the middle of Lower Saxony’s Wadden Sea lies Norderney – a sea that has been a UNESCO World Heritage Site since 2009. The East Frisian island is a climatic health resort and spa. That’s why freight forwarder Georg Fischer has recently turned to electromobility. A native of Norderney, he is the fourth generation of his family to run the island haulage company “Johann Fischer”. His fleet includes 35 MAN vehicles – among them several semitrailer tractors and, since about a quarter of a year, three MAN eTGEs. With the electrically powered transporters, he wants to set an example. Holidaymakers are very nature-conscious, he says, and Norderney is known throughout Germany.He is one of the first companies on the North Sea island to switch to electric mobility.

“If we set a good example here, that radiates out.”

– Georg Fischer

Vehicle fleet for transporting goods on the islands

Georg Fischer is a “reception forwarder” for Norderney and the other East Frisian islands. Its core business is distribution services along the North Sea coast. He operates a large warehouse in the town of Norden, where the other forwarders unload their goods, and delivers them to the ferries six days a week with his own vehicles. He also travels for grocery and drug store chains. He picks up the goods from their central warehouses and then transports them to the stores on the islands. He even transports building materials with his fleet of vehicles specially tailored to the island. 85 employees are on the road for him and active in the warehouses in Norden and on Norderney.

Delivery service to the hotel

Since larger trucks are allowed to cross the island by ferry but are not allowed to drive across the island, the freight forwarder handles the goods directly in the warehouse at Norderney harbor. From the articulated trucks, they are loaded onto smaller vehicles – including the battery-electric transporters that take drinks, food and parcels from the warehouse through the narrow alleyways to the hotels, guesthouses and stores. The suitcases of the vacation guests are also delivered directly to the vacation domicile by the electric transporters.

For Georg Fischer, the three vehicles are an ideal addition to its fleet. The range of up to 130 kilometers is absolutely sufficient for the distances on the island. Often, one battery charge is enough for two full days of work. The three vehicles are charged at wallboxes directly at the warehouse. The eTGEs are quiet and hardly disturb the tourists who are looking for peace and quiet on Norderney, says Georg Fischer. He is also convinced of the driving comfort: “You quickly get used to the electric drive. After all, an all-electric van like this has no gearshift and delivers full power to the axle.” In addition, he says, the eTGEs offer the comfort he has been used to for many years. “I am absolutely convinced of the quality of my vehicles, the workmanship, the reliability – nothing squeaks or creaks,” he says.
