The leather tanning industry of Sukanggang Garut is an that has the potential to produce wastewater contains a lot organic substances. Therefore, it necessary conduct effective test determine parameters pollution in industry. purpose this study was value water pH, Chemical Oxygen Demand (COD), Biochemical oxygen (BOD), Total Suspended Solid (TSS), and amount chromium concentration sample taken....
‘zaferani’ peach, an important native iranian fruit, is a highly perishable fruit of limited shelf life. in the present research, effects of modified atmosphere packaging with three gas combinations (5% co2 + 2% o2, 10% co2 + 2% o2 and air) and two packaging films (polypropylene and low density polyethylene (ldpe)) on physicochemical characteristics and shelf life of 'zaferani' peach ...
We present a seasonal and baseline survey of selected physicochemical parameters in epipelagic samples from Qua Iboe (QIB) and Cross River (CRV) estuaries in Niger Delta region of Nigeria. The parameters analysed were temperature, pH, salinity, turbidity, total suspended solids (TSS), dissolved oxygen (DO), biochemical oxygen demand (BOD), total organic carbon (TOC), total nitrogen, available p...
A detailed study was carried out with the postharvest mangoes (namely, the Langra and the Khirshapat) treated with different levels of Bavistin DF (BDF) solution (namely, 250, 500, and 750 ppm) for obtaining results on biochemical changes as well as storability of postharvest mango. The experiment was laid out in randomized complete block design with three replicates. The results of the experim...
In this study, the effectiveness of chitosan coating treatment to control weight loss and maintaining fruit quality of apricot was investigated. Fruits were coated with 0.25%, 0.5% and 0.75% chitosan as well as distilled water (control). Following treatments, fruits were stored at 0?C and 80 ? 2% relative humidity for 25 days. The weight loss, total soluble solids (TSS), titratable acidity (TA)...
Background and purpose: In Electro/Fe2+/persulfate process, persulfate radicals are produced as powerful oxidizing agents which increase the efficiency of this process. The aim of this study was to investigate the efficiency removal of COD, TSS and dye from industrial effluent in Buali industrial area in Hamedan. Materials and methods: In this study, the batch experiment was performed using a ...
to prolong the storage life and quality of 'zafarany' peach, fruits were treated with uv-c irradiation with dosage of 1.435×10-4 wcm-2 with three time durations (0, 5 and 15 min) and as well immersion of fruits in 0 and 3% cacl2 solution. the experiment was carried out in a completely randomized design (factorial experiment) of four replications. fruits were harvested in commercial ma...
یکی از عوامل بازدارنده استفاده از کاه گندم به عنوان یک منبع لیگنوسلولزی غیرچوبی با قابلیت مناسب جهت تولید خمیر کاغذ، پراکندگی آن در مناطق مختلف است. با توجه به اینکه کارخانجات بزرگ مشکلاتی از جمله جمع آوری و نگهداری الیاف غیرچوبی را پیشرو دارند، تاسیس کارخانجات کوچک می تواند یک راهکار مناسب باشد. در این نوع کارخانجات کوچک، به دلیل هزینه بالای سرمایه گذاری، طراحی و ساخت بخش بازیابی مواد، به ل...
Background & Aims of the Study: The most important compounds in hospital wastewater are antibiotics, disinfectants, anesthetics, radioactive elements, static cytotoxic agents, other chemicals and hazardous materials that caused to be different domestic sewage. The purpose of this study was the evaluation of performance of extended aeration biological system in pollutants remova...
