Networking – for efficient processes Networking is clearly the mega-trend over the coming years. This applies to automobiles, to our working life and leisure activities. Our surroundings are becoming smarter. Intelligently networked machines and installations are supporting us more than ever before. Optimised interlinking of the individual components within a complete system is the key to achieving maximum efficiency. Data is converted to useful information, which when combined in a transparent and clever manner create a massive leap forward in knowledge. This applies particularly to the water...

Systematically better Water is a precious resource. It is the basic component for humankind and for nature. Because of this the supply and disposal have taken on a worldwide key role in securing peace, growth and prosperity. With our creative and solutions oriented engineering development, HST plays an active role in designing environmental protection systems. Our fundamental conviction for the future is the benefit of networking. By using IT and automation, we create integrated communications between intelligent machines and plant in order to be able to control them in an intelligent manner...

Performance that runs smoothly For „intelligent “systems to work it is essential that all component parts fit seamlessly into each other. To do this it is necessary to identify the inter connections and think laterally. For this to succeed one must know every detail of the system. Ideally the system should have been developed in house. For this reason HST offers not only the networking (IT and automation) but also the networked parts (machinery and plant) as well as the maintenance and servicing. During the last 30 years and based on our experience with over 8,500 projects one thing has become...

Always thinking of solutions: HST- CEO Martin Frigger

„We think further“ Interview with HST Managing Director Martin Frigger on the strategic networking of the company with regard to products and projects in conjunction with economical and scientific solutions. How does HST network products and projects? Frigger: HST networks plant and machinery with IT and automation. Our plant and machinery receive their “intelligence” by web based networking and a very fine sensor technology. By this means they automatically supply important information and impulses to the user. I remember a report a few years ago when it was stated that a refrigerator was being...

Structures for CSO reduction Systems and solutions for: Storm water retention basins and deep storage tunnels 1 RSK/P-Flap Valve Page 35 AWS-Flush Bucket Page 37 12 AWS-Jet Cleaner Page 40 13 Lamella separators Page 47 Extreme weather events with heavy rainfall are frequent features of climate change. Housing development and paving of green spaces are increasing the run off volume entering the sewer networks, often beyond their capacities. The polluted excess water either causes flooding of urban areas or it is released directly into local waters, known as combined sewer overflow (CSO). Both scenarios...

Municipal treatment plants constitute a large part of the energy usage in a municipality. In order to save costs it is essential to achieve a measurable improvement in resource usage. The higher standards for effluent quality of the treated waste water discharge together with demographic changes affect the planning of new installations and the, refurbishment or upgrade of municipal treatment plants. The daily fluctuations in the inflow rate of the waste water means that simple flow-through plants are not the solution. For this reason more and more SBR plants are being used for aerobic treatment plants....

SensoMatic-EMA KANiO® SCADA.web TeleMatic Prognosis According to IPCC and other experts extreme weather events and very high levels of rainfall will be more frequent features of climate change. This increases the risk of flooding and the potential for subsequent damage. Depending on the local topography it may be necessary to protect residential areas from the effects of flooding by building storm water retention tanks or by the provision of storm water or combined sewer pumping systems to pump into the receiving water. This will ensure that predetermined high water levels are not exceeded....

Heat from Sewage 1 Pure flux P Page 50 Pure flux P2 Page 51 STW/V Scum Baffle Energy prices will continue to rise. This increased cost pressure together with the need to reduce carbon emissions require new methods for handling resources and recovery of the available energy. The options for heat recovery from sewage is now being examined by the experts. The potential is huge. By making use of the heat which can be extracted from sewage about 10% of the buildings In Germany could be heated. Sewage supply is reliable, available and contains heat energy which has already been paid for. The technology...

Flexible through standardisation HST is a specialist for system solutions with its own products: from the purely mechanical or automated weir to system waste water treatment plants, from the station technology to the complete control technology and the superordinate operations management system for installations in the infrastructure. The use of standards in HST products and systems and the simultaneous openness and flexibility for other intelligent systems within the system technology are a significant unique selling point and guarantee investment security and supplier-independence for all of...
