[ 1 ] - اهمیت و نقش سیستم های تصفیه آب برای واحدهای همودیالیز
Water treatment plays a vital role in the delivery of safe and effective hemodialysis (HD). Ensuring that water quality meets the American Association for the Advancement of Medical Instrumentation standards and recommendations (or equivalent) is necessary to reduce the incidence of chemical hazards and endotoxemia associated with the use of water for HD. This review will discuss the principles...
[ 2 ] - بررسی میزان حذف آنتی‌بیوتیک سیپروفلوکساسین در طول فرآیند کمپوست مشترک
Introduction and purpose: The growing trend of using antibiotics to control human and animal diseases and lack of attention to the disposal of medical, hospital, and pharmaceutical industry wastes have led to the emergence of environmental problems. regarding this, the present study was conducted to determine the antibiotic degradation of ciprofloxacin during the composting&...

[ 4 ] - 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 ...
[ 5 ] - Hospital wastes management in Mazandaran Province with emphasis on genotoxic waste management
Background and Objective: Hospital wastes with the content of infectious, pathologic, sharp, pharmaceupitical and genotoxic materials are classified as hazardous wastes. Of which, genotoxic residues wirh mutagenic and teratogenic effects are of most great concern on human health. Genetic wastes are referred to as cytotoxic, chemical, and radioactive drugs used to treat cancer or treat transplan...
[ 6 ] - 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...
[ 7 ] - Feasibility of treating the produced sludge in municipal wastewater treatment plant using ozonation method
Background and Objective: Wastewater treatment and stabilization always imposes costs and consequently a lot of energy on wastewater treatment plants. To achieve the purification and stabilization of as much sludge as possible, breaking complex components into simpler components is considered a critical step. Therefore, this study aimed to evaluate the feasibility of treating the produced sludg...

Materials and Methods: This study was performed in 2019 in Fardis city of Alborz province. In this study, 100 samples of food contact surfaces and 48 samples of staff hands were collected f...
[ 9 ] - Performance evaluation of modified up flow septic tanks reactor for treatment of synthetic wastewater
Background and Objective: Considering 829000 annual diarrhoeal deaths due to water pollution worldwide, the World Health Organization has emphasized that countries should reduce this rate by upgrading their wastewater treatment systems. The purpose of this study was to evaluate the performance of a modified up flow septic tanks reactor for treatment of synthetic wastewater. Materials and Metho...
[ 10 ] - Studying Removal of PHCs from Deposits of Petroleum Storage Tanks by Ozonation Method: Determining Optimal Conditions by Central Composite Design Method
Introduction: The increasing trend of petroleum production in Iran and lack of proper and systematic management of waste products in the deposition of petroleum storage tanks have made the existing hydrocarbons as a major hazards to the environment. In this study, the ozonation process was used to remove the petroleum deposits. Materials and Methods: In this experimental study, effects of pH, ...
