introduction: the development of an appropriate model for the quality control of an industrial wastewater treatment system can save the time as well as the cost. this study was performed to determine an appropriate model in order to predict the cod and tkn parameters by bod5 and nh4+ in the meybod industrial estate waste water treatment plant (wwtp). methods: this descriptive – analytical study...

This study investigated the efficiency of a sequential system involving surface flow and vegetated sub-surface constructed wetland (CW) in treatment Brewery Wastewater. Six experimental CW (2 4 subsurface flow) control (1 2 with 200 mm depth 19.05 diameter granite 100 sharp sand as substrate were used for experiment. The CWs planted locally available macrophytes: water hyacinth (Eichhornia cras...

The objective was to determine the effect of inoculum concentration on degradation Diesel 2 by a microbial consortium called BIOT.PD001. For this, five systems were designed (in triplicate), which Contained Davis Minimum Medium, 5% as carbon source, and suspension BIOT.PD001 (9 × 108 cells/mL) in concentrations 2, 4, 6, 8, 10% final volume. monitoring carried out indirectly through bacterial co...

In Peru, many effluents from domestic wastewater treatment plants often contain high concentrations of biological, physical or chemical contaminants; constituting low quality effluents. this context, the aim research was to evaluate effect produced by bacterial strain Pseudomonas putida ATCC 49128 on variation biochemical oxygen demand (BOD5) extracted plant (WWTP) located in town Collique, dis...

شرایط افروزش و اشتعال سوخت‌های گداخت هسته‌ای در حضور ناخالص­‌ها، یکی از موارد مهمی است که طراحی قرص‌های سوخت باید مورد توجه قرار گیرد. این مقاله اثر ناخالصی هسته سنگین طلا بر کلیه فرایندهای احتراق پلاسمای غیرتعادلی دوتریم- تریتیم مدل چهار دمایی آن شکل تابع توزیع انرژی رفتار فوتون‌ها تأثیر می‌گذارد بررسی گرفته است. مطالعه شامل اثرات منفی سوخت، طول زمان تشکیل لکه داغ نتایج محاسبات عددی به­ دست آم...

The Beshar River is one of the most important aquatic ecosystems in the upstream of the Karun watershed in south of Iran which is affected by point and non point pollutant sources . This study was done in order to evaluate the effects of pollutants activities on the water quality of the Beshar river and its aquatic ecosystems. This river is approximately 190 km in length and situated at the geo...

This study demonstrates the influence of lysimeter operational condition and tropical seasonal variation of leachate characteristics generated from municipal solid waste (MSW) deposited in landfill lysimeter at KUET campus, Bangladesh. Three different situations of landfill were considered here as well as both the open dump lysimeter-A having a base liner and sanitary landfill lysimeter-B and C...
