This work dwells on the performance evaluation of saline landfill leachate treatment for removing concentrated ammonia Cal-nitrogen, NH3-N (3449 mg/L) and suspended solids, SS (1035 mg/L) by using clinoptilolite. The treatment efficiency of both contaminants was investigated via a batch experiment involving five vital variables of specified ranges including particle size (75 to 355 μm), adsorbent dosage (10 to 140 g), reaction time (5 to 70 min), pH (5 to 10), and stirring speed (50 to 400 rpm). The study revealed high removal capacities of NH3-N and SS up to 59% and 57% respectively, achieved at respective optimum operating variables of 75 to 150 μm, 110 g/750 mL, 60 min, pH 9, and 250 rpm. The adsorption equilibrium mechanism suited well with the Langmuir isotherm and pseudo-second-order kinetic models. The procedure is potential to be employed for the remediation of high concentration pollutants in mature and methanogenic saline landfill leachate as an integrated process with other methods either as a pre or post-treatment. However, a pilot plant test is recommended to further establish the treatment design criteria prior to its real application in the field
There are many types of discharge detection method being studied in the past to monitor insulator surface discharges with new methods being introduced from time to time. Recently, measurements on the ultraviolet signals emitted during insulators' surface discharges have shown to be a good method to detect surface discharge from the insulator transmission line. The most common method is the ultraviolet imaging method and ultraviolet pulse method. However, the ultraviolet imaging method is known to be expensive. Hence, laboratory investigations were carried out where UVTRON R2868 Flame Sensor was used to detect the ultraviolet signal emitted from insulator during discharge activities. In this study, the insulator samples used were glass and ceramic type of pin insulators to verify the effectiveness of flame sensors in detecting ultraviolet pulse from both types of material of insulator. Day and rainy conditions were also simulated in the environmental chamber for both type insulator materials. Various discharge intensities were generated to closely mimic the service condition by varying the applied voltage in order to study the correlation between the ultraviolet signals of various discharge levels with the type of insulator material. At the end of the study, the result shows that the flame sensor could detect the ultraviolet pulse emitted from both types of pin insulators during the day and rainy conditions. This study illustrates that the ultraviolet pulse method using the UVTRON R2868 flame sensor is another potential tool to monitor the insulator surface condition during service
