Adsorption Apparatus | OperatiX – 13
The Adsorption Apparatus OperatiX – 13 demonstrates dissolved material removal using two activated carbon adsorbers in a closed water circuit. This Adsorption Apparatus allows variation of adsorbate concentration, contact time, and water temperature to study adsorption behavior. It includes 8 sampling ports for plotting breakthrough curves and concentration profiles. Optional DAQ software enables measurement and calculation of results.
The Adsorption Apparatus OperatiX – 13 shows how adsorption can be used to remove dissolved materials from raw water. This Adsorption Apparatus moves water through two activated carbon absorbers in a closed circuit using a pump. It allows adjustment of adsorbate concentration and contact time to study adsorption behavior.
Product Overview
This device shows how adsorption can be used to remove dissolved materials. The compounds that are dissolved in the raw water during adsorption are referred to as adsorbate. Water is moved by a pump from a tank to two activated carbon absorbers in a circuit. The first Adsorber receives treated water from the pump. Using a metering pump, a concentrated adsorbate solution is injected into the stream of treated water.
The raw water produced in this way enters the Adsorber and flows through the activated carbon fixed bed. Here the adsorbate adsorbs on the activated carbon. To remove any quantities of adsorbate still present from the water, the water then flows through a second Adsorber, the safety Adsorber. The treated water is returned to the feed line of the first Adsorber where concentrated adsorbate solution is added once again.
As a result, the water circuit is closed. Both pumps’ flow rates can be changed. This Adsorption Apparatus allows the following parameters to be varied: concentration of the adsorbate in the raw water, and contact time of the raw water with the activated carbon.
The temperature of the water can be regulated, making it possible to examine how adsorption is impacted by temperature. Pressure, temperature, and flow rate are all continuously monitored. Plotting of breakthrough curves and concentration profiles is possible thanks to the placement of the sampling points. Technology for analysis is needed to assess the experiments. The adsorbate being employed determines the analysis technology to be used.

Construction and Design
The Adsorption Apparatus OperatiX – 13 is built around two adsorbers, each with a 75mm inside diameter, 600mm height, and 2500mL capacity. Both adsorbers are filled with activated carbon. The second adsorber functions as a safety Adsorber to protect the closed water circuit. 8 sampling ports are positioned on the adsorber, with sampling valves set 100mm from the bottom and 50mm apart from each other. A circulation pump moves water through the circuit at a maximum flow rate of 0.15 to 2.5LPM and a maximum head of 5bar. A metering pump injects concentrated adsorbate solution at a maximum flow rate of 0 to 4L/h and a maximum head of 8bar. A 3-stage heater, rated 3x1000W with a maximum power of 3000W, controls water temperature, displayed digitally. A feed tank and an adsorbate tank each hold 50L.
Software
Software OperatiX – 13 (optional). DAQ software specially designed in National Instrument™, LABVIEW™ environment to measure and calculate the results of the apparatus. The software is optional; a set of electronic sensors is included when the software is used. The software can be run in any Windows™ environment.
