German technology for safe drinking water treatment in Africa

Wertheim, June 18, 2024 - Flawless and affordable drinking water for everyone in the world by 2030: this is one of the UN's ambitious sustainability goals. Especially on continents such as Africa, where water supply cannot be taken for granted in many areas, efficient water treatment is crucial. Suitable technologies will be on display at the Water Africa 2024 trade fair, which takes place from June 26 to 28 at the Accra International Conference Center in Ghana. Lutz-Jesco will be presenting the B3 mobile drum pump and the Memdos Smart dosing pump for wastewater treatment plants and waterworks (Stand D12).

Turn on the tap and enjoy a refreshing sip of cold water: This is by no means a matter of course for everyone. "2.2 billion people worldwide have no access to clean and safe drinking water. Around half a billion of them live in Africa. For them, life-threatening diseases, which in the worst case can develop into epidemics, are part of everyday life," says Heinz Lutz, Managing Director of Lutz Holding. "In view of these alarming figures, it is clear that access to clean drinking water is an urgent global challenge that must be tackled together." For this reason, the company is presenting new technologies that support efficient water treatment at the Water Africa 2024 trade fair.

Memdos Smart: dosing pump for water treatment can be operated intuitively like a smartphone

The Memdos Smart, a stepper motor dosing pump that helps to improve water quality in small sewage treatment plants and waterworks, will be on display at the trade fair. Among other things, the pump is used to introduce flocculants into the water. These agents are used to combine turbidity and suspended particles into larger units that are easier to separate. "Precise dosing is crucial for the quality of the water treatment," says Steffen Roth, Head of Development at Lutz-Jesco GmbH. "We have therefore equipped the Memdos Smart with a stepper motor controlled by a microprocessor." The special feature: unlike standard motors, it is possible to run the motor of the diaphragm pump asynchronously. During suction, it operates at a higher speed in order to draw in the liquid more quickly in the event of a stronger vacuum, while it operates at a lower speed during controlled and even discharge. "Thanks to the stepper motor, we achieve an almost constant flow rate, which enables gentle, low-pulsation and precise dosing of chemicals for water treatment in small sewage treatment plants and waterworks." The Memdos Smart is available in eight performance levels - with flow rates between 2 and 180 liters per hour. The Memdos Smart is also intuitive to operate. Roth: "The full-color touch display with smartphone-like operation sets us apart from other market players. Users can understand and execute all functions immediately, even without operating instructions. This makes controlling the pumps much faster and less prone to errors.

Battery-operated drum pump for remote areas with weak infrastructure

Lutz-Jesco will also be showcasing the B3 Battery at Water Africa 2024, a new battery-operated drum pump that brings mobility and energy independence to water and wastewater management in remote areas with weak infrastructure. It works with a brushless 320-watt DC motor that offers a delivery rate of up to 180 liters per minute and a delivery head of 11.8 meters of water column. "With the new B3 Battery, we have succeeded for the first time in making the performance of a battery-operated drum pump comparable to that of cable-connected versions," says Michael Raabe, Head of Sales at Lutz Jesco GmbH. One battery charge is enough to empty a 200-liter drum 14 times - in around 15 minutes. At a lower speed, an IBC container with 1,000 liters can be pumped out 5.8 times in 51 minutes. The pumping station is available in different versions to pump as many chemicals as possible for water treatment, including a version made of polypropylene (PP) for sodium hydroxide and polyvinylidene fluoride (PVDF) for chloric acid.

system produces disinfectant from commercially available salt tablets

At Water Africa 2024, visitors will also have the opportunity to talk to experts about water disinfection technologies from Lutz-Jesco, such as the EASYZON L, a chlorine dioxide system for small waterworks, and the MINICHLORGEN electrolysis system, which can be used to produce the disinfectant sodium hypochlorite from commercially available salt. It is used in mobile waterworks in Ukraine, among other places.
