PEAC 计算机控制吸附设备

The Computer Controlled Adsorption Unit, "PEAC", designed by EDIBON, enables the detailed study of the adsorption process in physico-chemical water treatment systems, accurately reproducing the behavior of two activated carbon columns arranged sequentially. The unit allows research on mass transfer between the liquid and solid phases, the construction of breakthrough curves, and the evaluation of adsorbent efficiency under different operating conditions.

This unit provides a practical approach for both training and research, allowing real-time observation of how adsorbate concentration, contact time, temperature effects, and flow rate influence the saturation of activated carbon. Computer-controlled operation facilitates continuous monitoring of the critical process parameters and enhances experimental repeatability.

The design of the unit integrates a stainless-steel feed tank with a heating system, enabling the study of temperature influence on adsorption kinetics and capacity. The dosed addition of the adsorbate, performed by a computer-controlled peristaltic pump, makes it possible to set the inlet concentration precisely. The hydraulic circuit incorporates a main pump, also computer-controlled, together with a flow sensor for monitoring the operating conditions.

The process takes place in two transparent, removable adsorbers containing the activated carbon. Each column includes multiple sampling ports distributed along its height, enabling characterization of the concentration profile evolution and the advance of the mass-transfer zone. The valve system allows the selection of open- or closed-loop operation, modifying the residence time and the number of passes through the adsorbent bed.

The unit includes temperature sensors at relevant points of the process, as well as level switches for safe operation of both tanks. All main components are mounted on a robust benchtop structure with wheels for mobility, a front panel with a functional diagram, and stainless-steel metallic elements for durability and ease of maintenance.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
