Environmental Engineering apparatus

Product Details:

The present set-up consists of 2 Nos. upward flow packed bed reactors. The set-up is designed so that the reactors can be operated either parallel or in series. A buffer tank is provided in between the reactors to permit the discharge of excess flow from the first reactor when the second rector is operated in series but at a low flow rate. Individual Peristaltic pumps are provided for each packed bed reactor to set and control the flow rate of liquid. Two heaters surround the reactor to heat the liquid passing through the reactor and temperature of the liquid in reactor can be controlled by means of Digital Temperature Controllers provided individually for each reactor.

The gas collecting vessels (2 Nos.) are provided and gas can be collected using volumetrically calibrated collecting vessel, which collects the gas based on water displacement method. A constant head, liquid seal device ensures that the gas pressure in the reactor is maintained at a constant level throughout the run. The vessel can be refilled with water during the run without breaking the liquid seal.

Sampling of liquid and gas can be done with the help of provided sampling port at appropriate positions. Non-return valves and siphon break are provided to ensure that each reactor is running at constant volume. Further this arrangement also prevents the danger of accidental symphonic action.

Product Details:

The present set-up consists of a reactor vessel. Liquid and air are fed to the reactor by means of a Peristaltic Feed Pump and a small capacity Compressor, respectively. Flow rate of air can be regulated and controlled with the help of Rotameter. Liquid level can be maintained in the reactor using overflow device connected to the water annular chamber of the vessel. Water is drawn from feed tank to overhead tank with feed pump coupled to DC Motor. A suitable spider-arm dispenser is provided in the bottom of the reactor vessel to distribute the air thoroughly for sufficient bubbling and stirring for reaction. The cylindrical wall of reactor is made from porous material to retain the suspended particles. It can be easily removed for cleaning purpose. Clear water passes through outer annular exit chamber. A heater is provided in the reactor vessel to heat the liquid and its temperature is maintained with provided PID Controller. The reactor lid contains a gas exit pot for sampling the gas for analysis. A Dissolved Oxygen Meter and pH probe accompanies the apparatus, which allows to conduct the experiment with ease.
