1 Aquatronics By 2030, 47% of the world s population is expected to live in regions without access to safe drinking water. This already applies to 900 million people today, which makes ensuring a stable and sustainable supply of water a central concern worldwide. The use of water supply and treatment technologies, and training in these fields, are subject to widely varying standards worldwide. A large amount of public wastewater flows back into rivers, lakes, and oceans completely untreated. In regions where sufficient technical training is not offered in this sector, planning even simple water supply and treatment plants is not possible, nor can existing plants be maintained, analyzed, and optimized. This makes it impossible to address high water losses during treatment transport as well as shortcomings in the treatment process, to the detriment of the local population s health and economic prosperity. Festo Didactic developed the Environmental Discovery System (EDS ) Water Management System in order to qualify specialists through hands-on training to deal with these challenges, which appear in many regions all over the world. EDS simulates and documents the entire cycle of human water consumption. The complex system of water supply and wastewater treatment is structured into well-arranged, coherent training steps in a comprehensive and practical method. Covered topics include: Course 1: Water purification Course 2: Water supply Course 3: Wastewater transport Course 4: Wastewater treatment Course 5: Monitoring, controlling, and optimizing plant operations Course 6: Energy optimization in water supply and wastewater treatment systems Course 7: Fundamentals of closed-loop control technology For more information:

3 Aquatronics Course 2: Water Supply PA241 Designed for technical staff and Safe water transport and distribution is essential for the drinking water supply. Participants of this course will be familiarized with water transport control technologies to achieve the optimum distribution of drinking water to the consumer. To ensure a safe and efficient water supply, all relevant components need to function efficiently and form an effectively adjusted system. The course traces the flow of water from the source to the consumer. Pumps are a main focus, as they are widely used in water plants.

4 Aquatronics Course 3: Wastewater Transport PA251 Designed for technical staff and Various private and industrial consumers discharge their wastewater into sewer systems. The wastewater contains diverse substances of varying qualities and amounts: solids, liquids, and chemicals. Sewer systems ensure a safe and odorless transport to the wastewater treatment plant. Participants of this course are familiarized with characteristics of municipal wastewater, the technical background of the sewer systems and control technologies of wastewater removal and the related processes. The course traces the flow of wastewater from the consumer to the wastewater plant. Introduction to wastewater transport Principles of water flow in pipes Wastewater transport in gravity sewers: hydraulic capacity, impounding, and backwater Hydraulic capacity with the Prandtl-Colbrook formula Transport of solids Transport of solids in sewers with varying flow rates Operation of sewer systems Rain spillway Overflow basin Sedimentation and re-mobilization in a combined sewer system Impact of blockage in a sewer system Dry weather and rain flow differentiation and their influence on solid transport Effects of exceeding the hydraulic capacity Basic mechanism that led to first flush Function and types of rain overflow basins Role of the throttle device and the overflow Oct , 2015

5 Aquatronics Course 4: Wastewater Treatment PA261 Designed for technical staff and Over the years, wastewater treatment techniques and practices have evolved into a complex body of knowledge based on past practice, applied engineering, and new environmental sciences. The intelligent application of these fundamentals assures the safe function of a wastewater treatment plant with an acceptable effluent quality. This course teaches the principles, functions, and operations of a variety of basic wastewater treatment processes, with a focus on sedimentation and biological treatment. Introduction to wastewater treatment Pre-treatment and primary treatment Secondary or biological treatment Tertiary treatment Fundamentals of Sedimentation Important process parameters Zones of a sedimentation tank (settling tank) Outlet zone and sludge zone Types of clarifiers Tank construction General problems with all types of clarifiers Sludge formation and removal Operating the clarifier Sludge withdrawal systems Fundamentals of biological treatment (activated sludge) Factors that influence sedimentation processes Control sedimentation processes Activated sludge processes Consequences of overload in a wastewater treatment plant Measure and control the amount of oxygen needed Nov , 2015

6 Aquatronics Course 5: Monitoring, Controlling, and Optimizing Operations PA271 Designed for technical staff and Huge amounts of money are spent to treat water to ensure it is safe for human consumption. Millions more are spent to distribute the same water to our homes, schools, hospitals, and businesses. At the same time, millions of gallons of that valuable treated water are lost through leakage due to excess pressure. New technology enables more efficient methods of controlling the distribution of water. In addition, monitoring and controlling the processes in water and wastewater treatment plants plays an important role in ensuring good water quality. This allows over dosage to be avoided, thus preventing undesirable concentrations of chemicals and the associated negative consequences. The optimized process also helps to minimize the cost of chemicals and energy Pressure, flow, and fill level monitoring Closed loop control technology: Pump Continuous and discontinuous controllers Closed loop control technology: Proportional media valve Volumetric Flow Control Drain Control Closed loop control technology: Aeration Controlling the oxygen concentration Goals related to water and wastewater treatment Relationships within the processes Control strategies Control fill level Volumetric flow control Drain control Control aeration Dec , 2015

7 Aquatronics Course 6: Energy Optimization in Water/Wastewater Treatment Plants PA281 Designed for technical staff and It is essential that water and wastewater treatment plants are continuously optimized after being commissioned. This ensures that all the devices and units perform smoothly so that the water quality reaches the required level. Furthermore, since operating costs are the major cost factor during the service life of the plant, an optimized system consumes less electrical power, and results in reduced maintenance work and increased service life of the equipment. Pump stations and aeration account for a major share of the energy used in water and wastewater plants and therefore deserve special attention. Finally, energy optimization helps to minimize environmental impact.
