Simple and suitable treatment of swine slurry from small farms is paramount especially in sensitive areas. This paper evaluates the viability an innovative nature-based technology hybrid system (a Vertical Flow Constructed Wetland followed by a Horizontal both planted with reeds – Phragmites australis ) to treat for further land application or discharge water bodies reduced nitrogen impact. Phy...
Cessation of mining operations in Ducktown, TN, left 800-900 acres of barren copper mine tailings. Revegetation activities had met with limited success. In 1998, efforts for revegetation of the tailings materials began anew. The objective of this case history is to provide insight into decision making processes which resulted in conversion of 800-900 acres of barren mine tailings into a vegetat...
A comprehensive surveillance program was conducted to determine the occurrence of three cyclic volatile methylsiloxanes (cVMS) octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), and dodecamethylcyclohexasiloxane (D6) in environmental compartments impacted by wastewater effluent discharges. Eleven wastewater treatment plants (WWTPs), representative of those found in Southern O...
گیاهان دارویی در طول تاریخ بشر در درمان بیماریها استفاده می شدند.از این رو ما در این پایان نامه اثر آنتی باکتریال عصاره تام و فراکسیون های اتردوپترولی و آبی حاصل از گیاه calotropis procera را بررسی کردیم.در این مطالعه روش ما برای عصاره گیری روش liquid-liquid fraction بودوعصاره تامو فراکسیون های اتر دوپترولی وآبی تهیه شد.برای روش میکروبی از روش انتشار در محیط آگار استفاده کردیمو به روش چاهک پلیت...
Introduction: Since the existing methods to remove the hazardous material are associated with problems, recently, the tendency is to use Biosorption methods by Low-cost adsorbents: this was investigated in our project. This study was conducted to investigate the adsorption of lead and zinc from aqueous solution by using powdered excess sludge (biosolid) from sludge drying beds of municipal wast...
