enzymatic extract preparation from pseudomonas aeruginosa km110 under accession no. hq730879 with lipase activity (0.3 u/ml), was used to perform enzymatic hydrolysis pretreatment of a synthetic dairy wastewater with 1000 mg/l total fat content. the pretreatment was optimized for 48 h hydrolysis time, at 45æ% c with 10% v/v enzymatic extract. the biological treatment of synthetic dairy wastewat...

Industrial wastewater is of global concern due to its severe effects on the environment. Compared with municipal wastewater, industrial wastewater generally contains the high concentration of toxic or no biodegradable pollutants. In recently year, scientific showed that scallop could filtration wastewater. Therefore, it was decided to determine the mechanistic toxicity of wastewater contained N...

a newly developed natural rubber deproteinization process produces deproteinized natural rubber (dpnr) wastewater as an intermediate product containing a high concentration of sodium dodecyl sulfate (sds) and rubber. in this study, a novel process to recover the residual rubber and energy as methane from dpnr wastewater was developed. as a pretreatment, sds and residual rubber in dpnr wastewate...

Due to increasing scarcity of fresh water, use of unconventional water source (e.g., wastewater) in irrigation has now become important. However, inclusive information on the effects of wastewater on crop production and soil health is necessary for such intervention. This study was designed to evaluate these effects by demonstrating the contribution of municipal wastewater (hereafter called was...

Many wastewater managers in developing countries struggle with the daily operation of urban wastewater systems. Technically well-designed wastewater collection and treatments are often degraded and/or not properly functioning. In this paper, a realistic rehabilitation strategy is developed for the urban wastewater system of Coronel Oviedo (Paraguay), in which the actual performance is unsatisfa...

today as freshwater resources become scarcer, wastewater use is a major incentive option for conserving and expanding available water supplies. the aim of this research was to investigate the impact of normal irrigation water (well water), chemical fertilizer, and treated urban wastewater effluent on yield quantity and quality of broccoli under micro irrigation system. the accumulation of chemi...

the aim of this paper is to investigate the affects of untreated wastewater using yeast factory wastewater on the growth of rapeseed and two its dominant weeds: wild mustard (sinapisarvensis) and gares (eremopyrum bonaepartis). the research was performed in both laboratory and greenhouse based on factorial method and completely randomized design. the experimental factors include wastewater conc...

Untreated wastewater, particularly from hospitals and other healthcare facilities, is considered to be a reservoir for multidrug-resistant bacteria. However, its role in the spread of antibiotic resistances in the human population remains poorly investigated. We used whole genome sequencing to analyze 25 KPC-2-producing Enterobacteriaceae isolates from sewage water collected during a 3-year per...
