Tradition and future for innovative Water treatment plants Cologne

Water treatment Cologne with the latest measurement and control technology

There is hardly a city in Germany in which the supply of clean water has such a tradition as Cologne. For almost 2,000 years, fresh water for drinking or washing has bubbled out of the pipes of the Rhine metropolis!

Colonia Claudia Ara Agrippinensium – that was the ancient name of the city, which with up to 40,000 inhabitants was one of the largest north of the Alps. The longest aqueduct north of the Alps supplied the people of Cologne in Roman times with drinking water – the nearly one hundred kilometer long Eifel water pipeline. Up to 20,000 cubic meters of fresh mountain water flowed daily into the city’s public fountains, thermal baths and domestic connections.

As exemplary as the water supply was back then, as high-tech is the water treatment and feed today. The latest standards and state-of-the-art measurement and control technology make it possible to meet the demanding task of supplying people with the most important of all foodstuffs. Neomeris supplies products and technologies for state-of-the-art water treatment plants.

What does a water treatment plant consist of?

What does a water treatment plant consist of?

The essential components of a water treatment plant include mechanical, biological and chemical processes such as filtration stages, softening plants, reverse osmosis, disinfection stages, storage and distribution systems or pressure boosting. Measurement technology, control technology, online analyzers and other solutions guarantee compliance with the required standards.

In the softening plant, the dissolved salts found in any natural raw water are minimized by the ion exchange process. In this process, the water is passed over a resin that ensures the exchange of hardness builders such as calcium or magnesium salts for sodium ions. The calcium and magnesium thus bound to the resin is discharged into the wastewater during regeneration. In the process, the values are constantly monitored by modern water hardness measuring devices.

The reverse osmosis plant is the next step in water treatment. It filters further substances such as silicic acid or nitrates as well as residues of pesticides or medicines from the water. For this purpose, the water is forced through a fine membrane by means of pressure. This membrane retains the harmful substances and thus purifies the water. Precise measurement and control devices accompany the process.

Cologne drinking water: Treated to the highest standards

RheinEnergie – this is the name of the regional utility company for electricity, gas, heat and water. It supplies not only the megacity of Cologne, but also the neighboring towns of Pulheim, Frechen, Bergisch Gladbach and Brühl.

Hardly any foodstuff is monitored as frequently and as strictly as drinking water. This also applies in and around Cologne. Cologne’s drinking water is so clean that even baby food can be prepared with it without any problems. The RheinEnergie utility supplies around 186,000 cubic meters of water to households and businesses in its catchment area.

The supplier obtains the raw water from the Cologne Bay. A steady stream of groundwater runs through the landscape of the Rhenish low-terrace plain. This flow consists of percolated precipitation as well as surface water. Gravelly soil layers as well as heavy sand deposits filter the water in a natural way.

The Cologne water utility produces the water in its own well systems. Water treatment takes place in eight waterworks. The purified and treated water is fed into separate drinking water networks on the left and right bank of the Rhine. Daily water analyses, state-of-the-art laboratory technology and measuring devices throughout the city constantly monitor water quality. Even the smallest traces of undesirable substances can thus be detected.

A word about water hardness. Cologne’s drinking water contains dissolved calcium and magnesium compounds. For the most part, it is considered hard. Even the Romans preferred hard water to so-called soft water because of its full-bodied taste. Cologne tap water can be drunk without hesitation. The long soil filter passages, the activated carbon filtration in the water treatment plants as well as the most modern measuring and control technology guarantee the high quality. Even viruses such as the Corona virus are reliably filtered out. No chance for germs! (Source: RheinEnergie).

Water treatment: ultra-pure water for Cologne

Drinking water is the most indispensable food: no human being can live without water. Yet ultrapure water is subject to even stricter requirements for many parameters. It must be almost completely free of residues. Even those that are considered healthy for humans in certain concentrations, such as magnesium or minerals.

Ultrapure water is used for food production and is also used in the beverage industry. It is also used in semiconductor production. It is also needed in the pharmaceutical industry and medical technology. This is also referred to as pharmaceutical water. Water treatment is very complex and requires the most precise measurement and control technology applications.

Modern technology for process water treatment

Industrial plants and production facilities require process water. Even though it is not intended for human consumption, high quality requirements apply here as well. For example, the gas content, solids content, water hardness, pH value or electrical conductivity must meet the specifications. Microorganisms or legionella, for example, must be reliably eliminated. High-tech measurement and control technology is essential for this.
