The column is supplied filled with glass Rasching rings 9x9 mm, and also supplied with polypropylene Pall rings, for the replacement of the glass Rasching rings in order to be able to study the effect of the filler on the efficiency of the absorption and desorption process. The main element of the Absorption Desorption trainer is a column of 1400 mm. height and 80 mm in diameter made in glass. The plant has pressure taps at the bottom and at the top of the column and two intermediate taps, through quick couplings connected to a water column differential manometer that allows determining the pressure drop within the column and the effects of the speeds of the liquid and of the gas on the pressure drop within the column. In both cases, the column filling maximizes the gas liquid contact surface, so that it produces the maximum possible absorption or desorption.
The Absorption Desorption plant also has three intermediate samplers for sampling both the liquid phase and the gas phase and 4 temperature probes with digital display. In a flow meter positioned on the liquid inlet line can be displayed the liquid inflow. This flow meter is made of borosilicate glass and stainless steel with stainless steel float. The liquid is introduced through the top of the column through liquid diffuser, which permits the dispersion of the liquid and thus a better distribution of the fluid within the column. The liquid phase is stored in a tank of about 30 liters of capacity made of polyethylene. Water or absorption liquid is led into the reaction column through a metering pump, which allows setting the incoming water flow to the column.

A network of this kind can be quite extensive; line lengths of as much as 1000 metres and more are possible. This experimental unit is used to teach the initial basic steps in field bus technology based on the example of Profibus DP. Various terminal devices (slaves) are activated and read by a PC with a Profibus DP interface (master). Field bus technology plays a key role in modern-day process automation. The field bus permits networking of terminal devices such as controllers, sensors or actuators in the plant system (field level) with the higher-level control room (control level). The experimental unit includes a digital controller as well as analogue and digital input and output modules with a Profibus DP interface. A digital voltmeter displays the output signals. Digital signals are generated by switches and displayed by LEDs. Two potentiometers permit the simulation of input signals for the controllers.

Peristaltic Pump Learning System versatile pump keeps fluid uncontaminated as it moves through the system by utilizing a tubing system that prevents direct contact with the pumps working parts. The Peristaltic Pump Learning System also discusses peristaltic pump components, how to reduce pulsation, how to calculate and adjust the flow rate, and how to select proper tube sizes. The Peristaltic Pump Learning System covers the function, operation, and maintenance of peristaltic pumps, which are used in a variety of applications within the chemical, food, pharmaceutical, and biotechnological industries. As an example, peristaltic pumps are used to filter and circulate blood throughout the body during heart surgery.

The simplest type of sedimentation is the settling of a dilute suspension of particles which have little or no tendency to flocculate. In these circumstances, the prediction of clarification rates and their scale-up to plant design is relatively straightforward.
Sedimentation is a process used widely in the clarification of water and waste water. Particles settle from suspension in different ways, depending on the concentration of the suspension and the characteristics of the particles.
Information from batch tests for such systems forms a vital part of the search for the optimum design and operation of industrial sedimentation tanks. The Sedimentation Studies Apparatus allows demonstration of these different characteristics for any chosen sediment/water system. For higher concentrations where inter-particle effects become significant and where agglomeration may take place, different regimes of settling rate occur, known as 'zone' settling A.
Five equal sized glass cylinders are mounted vertically on a backboard incorporating measuring scales. Solutions containing different amounts of suspension can be placed in the cylinders and the differences in sedimentation rate observed by measuring the changes in height of the various solid/liquid interfaces with respect to time. Each of the cylinders may be removed from the board for washing, filling and mixing of the solid particles.
The whole apparatus is bench-mounted and provided with back lighting. An accurate balance (not supplied) is required for weighing the solids.
The equipment includes the following accessories necessary for a self-contained facility: stop clock, three plastic beakers of 2 litre capacity, specific gravity bottle.
The specimens are submitted to hydrostatic stress for a pre-set period. The water permeated through the test specimen is directly collected and measured into a graduated cylinder. It is therefore possible to determine the permeability coefficient in cm/sec. by the attached formula. The equipment consists of a strong metallic frame holding four cells which are hot-galvanized for anti-corrosion protection. Automatic Concrete Water Permeability Apparatus At Four Cells fully automatic apparatus is designed to carry out water permeability tests on cubic concrete specimens max.150 mm side and cylinder specimens max.160 mm diameter. Each cell includes a pressure control manometer.
