[ 1 ] - Medical waste management at health-care centers, clinics, and laboratories of Mahmoud Abad, Mazandaran
Background and Objective: Clinics, laboratories and health care centers are considered as one of the main waste generating sources in solid waste management. The problems associated with the generated health-care waste in clinics, laboratories and health care centers have been rarely investigated in Iran. Therefore, the present study was developed to investigate the status of health care waste ...
[ 2 ] - Comparative study of efficiency between 2,4 dinitrophenol removal using dry sludge and modified calcium chloride
Background and Objective: 2,4 dinitrophenol is observed in sewage produced from chemical and petrochemical industries. Contamination of drinking water with these pollutants causes toxicity, health problems and change in taste and odor. The present study was developed to evaluate the efficiency of removal 2,4-DNP through dried sludge adsorbent and modified calcium chloride sludge adsorbent. M...
[ 3 ] - Microbial Quality Investigation of Swimming Beaches in Mahmoudabad, Iran 2019
Background and purpose: Contamination of swimming beaches in north of Iran has caused environmental problems in recent years. Mahmoudabad is exposed to these dangers due to having the longest coastline in the country. The aim of this study was to determine microbial water quality of swimming beaches in Mahmoudabad. Materials and methods: In a descriptive-analytical study, we analyzed microbia...
[ 4 ] - Evaluating the Efficiency of Microwaved Sludge in the Removal of 2, 4-Dinitrophenol from Aqueous Solutions: Equilibrium and Kinetics Studies
Introduction: Nitrophenol compounds are toxic compounds found in industrial wastewaters. 2,4-dinitrophenol is the most dangerous compound among phenolic compounds. The aim of this study was to evaluate the removal of 2,4-DNP from wastewater by microwaved dried sludge adsorbent. Materials and Methods: The results of 2,4-DNP removal were discontinuously obtained by the high performance liquid ch...
