From space, our earth is a blue planet with seemingly vast water resources. However, only 2.5 % of this water is usable fresh water. At the same time, the increase in global population and rapid industrialization put enormous demands on the natural water resources. Water is becoming rare in the future. Against this backdrop, it is clear how important it is to man and industry to have an efficient, high-capacity potable water supply and to have eco-friendly wastewater treatment for the planet as well as for thew development of entire regions. At the same time, the increasing competition in...

The waterworks in the Westphalian town of Haltern Gelsenwasser AG, one of the Largest providers of potable water in Germany. With an annual delivery of around 105 million m3 of water, it ranks among the largest of its kind in Europe. The service area includes more than 20 communities of the northern Ruhr district and Munsterland. A total of a million people, including commerce and industry are reliably supplied with potable water and service water by the waterworks. 24 hours a day, 365 days a year. The Haltern waterworks is situated in a hydrogeologically favorable location, which owes its...

The well house - 100 % certainty, The untreated water is abstracted in the waterworks via groundwater wells or bank filtration wells and from dams and other types of surface water. A large number of waterworks have decided on the OPTIFLUX electro- magnetic flowmeter for monitoring the delivery rate into the well houses. And for good reason: because, compared to conventional mechanical Waltman meters, OPTIFLUX offers key advantages. There is the significantly lower pressure loss, for example, which has a positive effect on the power consumption of the pumps. Or the longer service life, due...

The pressure filter system - The heart of water treatment The quality of untreated water can vary widely in nature, depending on the extraction point. Therefore around one third of the entire amount of ground filtrate in the waterworks is conducted through a total of nine pressure filter tanks filled with quartz chips for the biological filtering out of manganese. This is where the core process of water treatment takes place. Because, in addition to flocculation, this is where the decision is made as to which suspended particles and colloids are filtered out of the untreated water and in...

12 Booster pump facility Booster pump works with collector well - Everything under control Maximum system availability is indispensable for a waterworks - whether during water abstraction, water treatment or transport. In the Haltern waterworks, a total of 16 rotary pumps with electric drives take on the task of supplying potable water to the public supply network. The largest pumps can transport 3,500 m3 of water per hour over an elevation of 110 meters. Do different water qualities and flocculating agents also mean different types of devices for measuring the flow? Not necessarily....

Flocculation system Corrosion protection Finding the right degree In waterworks, the untreated water from all of the vertical wells is consolidated in deep containers. Here, natron base liquor for increasing the ph value and monophosphate are dosed for protecting the pipeline network and home installation from corrosion. Optionally, a chlorine bleaching system can be connected for dosing, to prevent microbiological effects. These dosings require the use of a flowmeter, which stands out on the one hand due to its extraordinary measuring accuracy (±0.15 %) and which is also chemically durable...

The run-out - Clean and neat Flowmeters in the run-out of the waterworks and in the distribution network work in responsible positions. After all, they measure the potable water intended for the population and must precisely comply with the strict legal regulations. This also affects the selection of the flowmeter and its materials inside the measuring pipe. Thus, only sensors that have liners that are approved as per KTW and DVGW worksheet 270 as well as respective guidelines according to the UBA may be used in Germany. The OPTIFLUX from KROHNE meets these criteria and is the first choice...

Measuring the chlorine content Many municipal waterworks perform no permanent disinfection of drinking water. However, in many cases a process known as emergency chlorination takes place. The process is switched on in case of need, adding chlorine to the drinking Emergency chlorination is special in that it is only very rarely required, which means that non-chlorinated water usually flows through the measuring systems. Conventional measurement technology is now often faced with the problem of biological fouling covering the membrane, making the sensor inoperative over time. For this reason,...
