Well Construction Symposium
Minimising the use of pipeline washing agents

During the first day of the two-day Well Construction Symposium at WASSER BERLIN INTERNATIONAL the focus was on wash drilling and drill cuttings on well construction sites. In his introductory paper on the Thursday at the fair (30 March) Sven Tewes, Chief Executive of NORD Bohr und Brunnenbau GmbH, explained that the choice of dry drilling or wash drilling depended on the particular application, and that both methods have certain advantages and disadvantages. Wash drilling is used with certain diameters and depths, and this requires the addition of washing agents, but their use should be kept to a minimum. In northern Germany these consist of clay products based on bentonite, polymers, pH value regulators and weighting agents. In the future it will be necessary to minimise the use of wash drilling agents, to treat the wash in circulation, and to use drum and containers because flushing basins are now a thing of the past. The speaker also stated that drilling sites should be enlarged


European Day of the European Water Association
Urban design must adapt to the changing water situation

Urban designers will have to change their approach in order to meet modern demands for wastewater management. Many networks of pipes, and many buildings too, are not adequate to the challenges presented by climate change. In the past municipal authorities were primarily concerned with allowing precipitation to run off into rivers as quickly as possible. Nowadays the objective is to ‘harvest’ it, i.e. to take advantage of it and at the same time to respond to the reduced reliability of precipitation events, according to Malte Henrichs of Fachhochschule (Technical College) Münster, speaking at the European Day Forum at BERLIN WASSER INTERNATIONAL

Henrichs‘ institute has developed a software tool that enables calculations to be made about various possible scenarios involving precipitation in a variety of topographical, geographical, geological and demographic situations. Ideally every effort should be made to allow it to discharge into the groundwater or to be used for industrial purposes, keeping the unused run-off to a minimum. As an example of the methods applied Henrichs gave an example of the calculations made using the area around the former Oxford Barracks of the British Army of the Rhine in Münster. These included covering roofs with vegetation, ground-level basins and porous road and path surfaces, all of which make far better use of water falling as precipitation than is possible with customary approaches. However, he admitted that this scenario is not compatible with the desire to ensure greater profitability by sealing over built up areas, especially in regions with a thriving economy such as Münsterland. He was pleased to note that “our model is, however, included in urban land use planning"

Job opportunities in the water industry
Good chance of finding new employees

According to Nathalie Leroy, managing director of Hamburg Wasser, the water industry has a good chance of securing generations X and Z as future employees because it can offer them fulfilling work. The industry’s ability to offer a livelihood was a convincing argument, Leroy said, speaking at the Career Congress at WASSER BERLIN INTERNATIONAL. However, a change in corporate leadership style was needed which allowed workers to take greater responsibility. The fact that at Hamburg Wasser around half of the workforce was due to retire over the next 12 years presented a challenge. If people had to ultimately keep working until they were 70 employers would have to do more for social welfare and healthcare. Dominic Spinnreker-Czichon of the Danish engineering consultancy DHI outlined the qualifications future engineers had to bring along. They needed programming skills in order not to waste their time in overqualified positions. He made the case for process-based thinking as regards workplace structures, for breaking down barriers between corporate divisions and less strict working times. He also saw virtual reality as offering big opportunities in the water industry

Bürkert Fluid Control Systems
Continuous monitoring of all important water parameters

A reliable supply of water requires the efficient water analysis management, enabling those in positions of responsibility to safeguard supplies even when faced by increasing demand. Bürkert offers a future-proof solution with itsType 8905 online analysis system, because this modular system can be continuously expanded with new metering blocks. Other new additions to the analysis programme include sensoring blocks for iron (flow injection analysis) and the spectral absorption coefficients SAK254 (full spectrometer metering cubes) for determining water quality. Even the basic version of the online analysis system provides metering blocks for five different readings on a common platform: pH value, oxidation reduction potential (ORP), conductivity, chlorine and turbidity. There is also a sensoring block (Type MS02) which can offer a choice of obtaining readings for free chlorine or chlorine dioxide

POLOPLAST GmbH & Co KG
Working life in excess of 100 years

The one-piece POLO-ECO plus PREMIUM is a triple-layer wastewater pipe system that is available in ring stiffnesses of 10, 12 and 16 kN/m². In addition to offering outstanding reserves of safety it also has many applications, for example, for removing sewage or rainwater. The POLO-TC (TOP-CONNECT) sleeve system guarantees excellent laying reliability as well as saving time and money. The yellow mounting that is securely fitted inside the sleeve prevents the sealing ring from slipping out and thereby ensures maximum reliability during pipe laying and also when the sewer pipes are in operation. The choice of the best possible materials ensures that the POLO-ECO plus PREMIUM range of wastewater pipes has a very long working life. Long term testing and investigations have shown that, at a continuous operating temperature of up to 50 degrees Celsius and the correct processing, a working life in excess of 100 years can be expected

PolycarbonPlus GmbH
Adsorption with subsequent absorption

PolycarbonPlus is a patented system that is marketed under the product name of MesoFix and has been developed specifically for a number of applications in the purification and treatment of water and wastewater of various origins. MesoFix is a molecularly adsorbent absorber, made up from multiple components using a special carbon compound and other conditioned parts which are homogenously compounded in the form required for their particular use. The material is also available in the form of pellets and/or as granules, in pads, booms, mouldings of any required shape, or in bulk form, depending on where and how they are to be deployed. MesoFix adsorbs the entire group of hydrocarbons such as BTX, PAH and CVHC as well as crude oil and all its derivatives in both liquid and gaseous consistencies. The outstanding feature of the systems is its ability to adsorb contaminants with subsequent absorption. The exhibitor states that this effect is available for the first time on the world market
