Enhanced nitrogen removal in trickling filter plants.
The Beaudesert Sewage Treatment Plant (STP), originally built in 1966 and augmented in 1977, is a typical biological trickling filter (TF) STP comprising primary sedimentation tanks (PSTs), TFs and humus tanks. The plant, despite not originally being designed for nitrogen removal, has been consistently achieving over 60% total nitrogen reduction and low effluent ammonium concentration of less t...
متن کاملRemoval and transformation of organic matters in domestic wastewater during lab-scale chemically enhanced primary treatment and a trickling filter treatment.
To find a simple and economical way for treating the domestic wastewater in small counties and towns, a process combining chemically enhanced primary treatment and a trickling filter (CEPT-TF, representing the physical and biological effects) was constructed and operated in laboratory conditions. The characteristic behaviors of dissolved organic matter in raw wastewater and effluents were exami...
متن کاملChemically assisted primary treatment of municipal wastewater
The objective of this work is studying the use of chemicals to enhance primary treatment in municipal wastewater treatment plants, thereby reducing the cost of the secondary treatment stage. Jar tests using chemicals, polymers and sea water have been conducted to determine the best performing chemicals, alone and in combinations. The process performance parameters studied were pH, type and dosa...
متن کاملHonduras Wastewater Treatment: Chemically Enhanced Primary Treatment and Sustainable Secondary Treatment Technologies for Use with Imhoff Tanks
Wastewater treatment within Honduras is indicative of the state of water and sanitation services throughout the developing portions of Central America. One technology which comprises approximately 40 percent of all treatment facilities within Honduras is the Imhoff tank. First patented in 1906 the Imhoff tank has long been out of favor within the developed world as newer technologies and large ...
متن کاملNitrogen Removal in a Full-Scale Domestic Wastewater Treatment Plant with Activated Sludge and Trickling Filter
During the last decade, more stringent effluent requirements concerning the nutrients effluent values have been imposed by legislation and social concern. In this study, efficiency of total nitrogen removal in activated sludge and trickling filter processes (AS/TF) was investigated in Tehran North wastewater treatment plant. Biological system in this site was included, anoxic selector tank, aer...
