Beam Incident

The condensation coefficient of mercury was determined by measuring the number flux of a mercury vapor beam incident on, and reflected from, a liquid mercury surface. For a clean surface the condensation coefficient was found to be between 0.65 and 1.

Arc Current And Voltage

In a pulsed arc with mercury electrodes the average column field strength Eco was measured for different currents I, and the relationship [Formula: see text] was found. The variations of arc current and voltage with time indicate that the anode and cathode fall regions have a combined thickness of 3 × 10−6 cm, and an average field strength of 2 × 106 V/cm. The arc plasma is formed mainly from mercury vapor, rather than from the surrounding gas.

Set Up

The objective of this trial was to assess the application of UVA-LED technology as an alternative source of irradiation for photo-Fenton processes, aiming to reduce treatment costs and provide a feasible treatment for landfill leachate. An optimized combination of coagulation with ferric chloride followed by photo-Fenton treatment of landfill leachate was optimized. Three different radiation sources were tested, namely, two conventional high-pressure mercury-vapor immersion lamps (100 W and 450 W) and a custom-designed 8 W 365 nm UVA-LED lamp. The proposed treatment combination resulted in very efficient degradation of landfill leachate (COD removal = 90%). The coagulation pre-treatment removed about 70% of the COD and provided the necessary amount of iron for the subsequent photo-Fenton treatment, and it further favored this process by acidifying the solution to an optimum initial pH of 2.8. The 90% removal of color improved the penetration of radiation into the medium and by extension improved treatment efficiency. The faster the Fenton reactions were, as determined by the stoichiometric optimum set-up reaction condition of [H2O2]0/COD0 = 2.125, the better were the treatment results in terms of COD removal and biodegradability enhancement because the chances to scavenge oxidant agents were limited. The 100 W lamp was the least efficient one in terms of final effluent quality and operational cost figures. UVA-LED technology, assessed as the application of an 8 W 365 nm lamp, provided competitive results in terms of COD removal, biodegradability enhancement, and operational costs (35–55%) when compared to the performance of the 450 W conventional lamp.
