Kegiatan penambangan merupakian suatu komoditas devisa Negara. Namun dampak negative dari kegiatan sendiri diantaranya adalah sebagai penghasil air limbah yang mengandung bahan-bahan berbahaya, terlebih jika tersebut dekat dengan pemukiman penduduk serta ekosistem lainnya. Penelitian ini bertujuan untuk mengetahui lingkungan disebabkan khususnya dihasilkan proses pengolahan limbahnya. Analisis ...
Background and purpose: Quality of hospital wastewater is similar to municipal wastewater however, due to the presence of toxic agents and pathogens in hospital wastewater, if not already treated, it is dangerous to the environment and consequently to human’s health. This research was to study the wastewater treatment and disposal condition and the quality of hospitals effluent of Babol Ünive...
Background and Objectives: Wastewater treatment of paper recycling and cardboard industries with the aim of water recycling and reducing environmental impact is one of the daily needs of industries. Therefore, the aim of the present study was to optimize the conditions of coagulation and flocculation process in wastewater treatment of paper recycling industries using the response surface method...
The discharge of industrial waste into water bodies without significant treatment can be a source pollution. This study was conducted to assess the impact wastewater on quality in rivers around Bole Lemi Industrial Park (BLIP). Data were collected from six sampling stations midstream, downstream, and upstream locations between May June 2021. In situ (pH, electrical conductivity [EC], total susp...
هلوی رقم زعفرانی یکی از میوه‌های مهم بومی ایران است. این میوه بسیار فساد‌پذیر است و ماندگاری کمی دارد. در پژوهش حاضر تأثیر بسته‌بندی در اتمسفر تعدیل‌یافته با سه ترکیب گازی ( O22درصد + CO2 10درصد و O22درصد + CO2 5درصد و Air) و دو نوع پوشش پلاستیکی (پلی‌اتیلن با دانسیتة کم و پلی‌پروپیلن) بر خصوصیات فیزیکی و شیمیایی و انبار‌مانی هلوی رقم‌زعفرانی در طول 9 هفته انبار مطالعه شد. میوه‌ها بعد از بست...
This study aimed to evaluate the effect of rootstocks on fruit sugars, organic acids, and carotenoids. The contents of sugars and organic acids in fruits were determined by HPLC. Total acidity (TA), total soluble solids (TSS), and pH value of the juice were also evaluated. Total carotenoids and chlorophylls contents were measured using a spectrophotometer. The content of ethylene in fruits was ...
Physicochemical properties of banana peel flour (BPF) were studied in two varieties (Cavendish and Dream) and two stages of ripeness (green and ripe). BPF’s were analyzed for pH, total soluble solids (TSS), water holding capacity (WHC) at 40, 60 and 80C, oil holding capacity (OHC) at 40, 60 and 80C, colour values L, a and b, back extrusion force and viscosity, and the data were analyzed using...
research was carried out in 2007 on 7 native summer-ripening apple cultivars grown in kamal abad karaj research station. the 16 year-old plants were grafted onto seed rootstocks. the cultivars were ghandak-e-kashan, golab-e-isfahan, golab-e-kohanz, mashad, assali, ghermez-e-rezaieh and a new cultivar--koli-e-mahallat (syn. escr). the aim of the study was to identify changes in qualitative and q...
Background: Saccharomyces cerevisiae is one of the important yeast found to be superior in fermentation technology. Methods: The present study was undertaken periodical changes TSS, pH, acidity and alcohol content during process wine preparation from coconut water. With different TSS levels (7, 9, 11 13°Brix) adjusted with sugar 9°Brix optimized level. Result: constantly reduced until complete....
