Activated Sludge Process enables this process to be demonstrated. A pump delivers raw water contaminated with dissolved organic substances (organic matter) into the aeration tank. Since aerobic microorganisms need oxygen, the raw water is aerated in the aeration tank. The activated sludge is mixed with the raw water by stirring machines. In the secondary clarifier the activated sludge is then separated from the treated water by sedimentation. The activated sludge process is the most important biological process in water treatment. Aerobic microorganisms (activated sludge) in the aeration tank use the organic matter as a source of nutrition, biodegrading it in the process. A portion of the activated sludge is returned to the aeration tank (return sludge). The treated water is collected in a tank. Oxygen concentration, pH-value and temperature can be controlled. The following flow rates are adjustable: raw water, return sludge, internal recirculation for pre-denitrification and air.

Materials Engineering Learning System uses industrial quality components to teach students how to evaluate and use different industry grade materials. The Materials Engineering Learning System allows students to conduct a wide array of tests including tensile testing on steel alloys.
Material strength properties affect the performance and safety of almost every product made. As technology has advanced, material choices have broadened and become more complex. Students learn industry-relevant skills in materials testing (tensile, compression, hardness, and shear), computerized data acquisition, chemistry of metals, interpretation of industry-standard numeric identification systems of various types of metals (steel, aluminum, brass, and copper), material strength analysis, and product design. Engineers and technicians alike must be able to select the proper material for an application and analyze material properties when a product fails.
Features:
Excellent preparation for study of engineering, manufacturing, industrial maintenance
Data analysis and problem solving
Understanding of realistic array of industrial materials such as steel, copper, aluminum, and brass

The unit is supplied with a detailed experimental operating and maintenance manual giving example experimental results and sample calculations.
The unit consists of a metallic base structure which provides the support locations for the structure. It has a spring balance which shows the elongation and hence the force acting on movable end due to the load applied on the top of the structure via a hanger. Three members are connected in a triangular shape to form a toggle joint. The base structure is fixed at one end but its other end is movable.
This unit is designed to study the characteristics of toggle joint. Toggle joint is a structure which has three members connected in a triangular shape. Its length can change due to the load applied at the top of the triangular structure. Two of its members have fixed lengths but third member (base member) has a variable length.
The unit has an integral liquid crystal display with a scroll switchthat allows all 32 channels to be viewed in groups of four at any time. Theconditioned outputs of the pressure sensors, and any other connected compatibleelectronic instruments, may be output to Versatile Data Acquisition System toallow computer based data acquisition and display. The 32-Way Pressure Display Unit is an optional ancillary tomodular Subsonic Wind Tunnels. The unit mounts onto the control and instrumentationframe of the wind tunnels. Connection to each of the 32 calibrated pressuretransducers is via quick-release pressure inputs mounted on the front panel ofthe unit. It measures and displays up to 32 pressures frommodels, Pitot-static tubes and other measuring instruments fitted to a windtunnel. It is ideally suited to applications where multiple pressuremeasurements are required, for example in boundary layer and tapped aerofoilmodel investigations. This allows easy and quick connection between the unit and anexperiment mounted in a wind tunnel. When the 32- Way Pressure DisplayUnit is used with the system it allows laboratory time to be used more efficientlybecause data can be captured and processed much more quickly than when usingmanual techniques. All pressures are measured with respect toatmosphere. Using enables accuratereal-time data capture, monitoring, display, calculation and charting of allrelevant parameters on a suitable computer. This option providessignificant experimental advantages over conventional instruments such asmanometers. The facility in the software to average data to remove thefluctuations inherent in wind tunnel measurements enhances the quality of theresults by making their interpretation much easier.
