The quest for an effective alternative means for effluent treatment is a major concern of the modern-day scientist. Fungi have been attracting a growing interest for the biological treatment of industrial wastewater. In this study, Saccharomycescerevisiae and Torulasporadelbrueckii were isolated from spoiled watermelon and inoculated into different concentrations of effluent. The inoculants wer...
Textile waste water treatment for industrial reuse remains as a complicated problem due to several reasons. Among them are: 1) Higher levels of Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Total Dissolved Solids (TDS) content of the waste water; 2) Non-biodegradable nature of organic dye stuffs present in the effluent. Thus, any adopted treatment system, especially with resp...
The preservation of water resources in modern urbanized society is a major concern. In this study, floating constructed wetland (FWT) pilot plant was designed and for the treatment polluted wastewater drain. A series experiments were run continuously year pilot-scale FWTs semi-arid area located Egypt’s Delta. Four aquatic species (Eichhornia, Ceratophyllum, Pistia stratiotes, Nymphaea lotus) us...
Palm oil mill effluent (POME) is wastewater containing dissolved materials with concentrations above the threshold. Generally, POME processing in Indonesia uses an open pond system. It less efficient because it requires large areas and causing greenhouse gas effects. This research aims to improve processing, three methods were studied; bioremediation using enrich indigent lypholitics bacteria (...
با افزایش جمعیت، رشد و توسعه ی صنایع و شهرها و در نتیجه ی آن رشد صعودی نیاز به آب، همچنین با توجه به کمبود فزاینده ی آب در ایران، بازیافت آب راهی مناسب برای تأمین نیازهای کشور می باشد. از راه های بازیافت و تأمین آب بخش های مختلف جامعه، تصفیه فاضلاب های شهری و استفاده مجدد از پساب حاصله است. در همین راستا عملکرد تصفیه خانه ی شهرک غرب تهران و امکان بازگشت پساب آن تصفیه خانه به آب های سطحی به جهت ...

This paper deals with the environmental impact of effluents released by denim garment washing factories in Bangladesh. Both untreated and treated effluent samples were collected from five identified as representative cases subjected to chemical testing a part case study. The results compared against acceptable limits parameters-chemical oxygen demand (COD), dissolved (DO), biochemical (BOD), to...
Greywater, a type of wastewater, may be hazardous to human health and ecosystems. Greywater is large fraction wastewater that needs adequate attention for remediation reuse in the agricultural sector so part water problem can sorted out. This study aims develop rapid method greywater treatment agriculture. A microfilter consisting sand, clay, organo-clay, charcoal, biochar was designed tested t...
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...
Water safety and security has become a great problem in recent years, as the shortage of water resources most countries is becoming an increasingly serious issue. Therefore, searching for new sources or treating contaminated major requirement to covering fresh water. The current study evaluated impact Trichoderma asperellum on physicochemical characterization agricultural run-off (AR) compared ...
