Title: Performance evaluation of several sequencing batch biofilm reactor with movable bed in treatment of linear alkyl benzene sulfonate in urban wastewater
Biography:
Surfactants enter the water and wastewater through the watery wastes of household washing machines and other washing operations as well as industrial wastewater. Surfactants are divided into several types including non-ionic, anionic, cationic and amphoteric. Anionic and non-ionic are the most common types of surfactants. Surface active substance or surfactants constitute the constituents, additives and fillers of four main chemicals in detergents. Surfactants are the most important chemicals in detergents and cleaners which are approximately 5 to 30 percent of the weight of the detergents. In 1960 the most common surfactants in detergents were alkyl benzene sulfonate which increased wastewater treatment problems due to its resistance to biodegradation.
Abstract:
Detergents are one of the major environmental pollutants that their consumption will be increased by increasing the level of the health of the countries which can cause many problems if they are not infiltered and exposed to the environment. Linear benzene sulfonate, after the soap is the most common household detergent and it is used in more than 100 countries around the world as a raw material for production of surfactants such as washing powders, dishwashing liquids and other detergents. Among the various methods of treatment, using technologies related to biological processes is very important. The aim of this study is to evaluate the performance of MSCR bioreactor in linear alkyl benzene sulfonate (LAS) removal from the municipal wastewater. In this research a Plexiglass pilot with the diameter of 5 mm, dimensions of 54*25*25 cm and total volume of 5.34 litres and used volume of 30 litres was used; containing 70

Title: Co-Digestion of Animal Manure and Alkaline Pre-treated Banana Peelings for Optimized Biogas Production
Biography:
The application of pretreatment methods can alter such properties and can improve biogas production. In this study alkali pre-treatment was applied to improve methane production potential from banana peelings and co-digestion with horse manure.Banana peelings were pre-treated by the addition of NaOH respectively with 3%, 6%, (by weight) at 55°C for 50 h using NaOH pre-treatment. After that pre-treated banana peelings and horse manure were stirred by the ratio
Abstract:
Anaerobic digestion is a biochemical process in which organic matter is decomposed in the absence of oxygen and produces methane gas. Therefore anaerobic digestion technology is an efficient method for energy generation from biomass. Lignocellulosic biomass, such as agricultural residuals and energy crops, is an abundant organic resource. The wastes with high lignocellulosic contents are resistant to biodegradation by enzymes and microorganisms do to their structural and chemical properties such as; cellulose crystallinity, accessible surface area, degree of cellulose polymerization, presence of lignin and hemicellulose, and degree of hemicellulose

Title: Fungicide applications and environmental efficiency of cocoa farmers in Ondo state, Nigeria
Biography:
Dr. F. A. Sowunmi is a Lecturer in the Department of Agricultural Economics, University of Ibadan, Ibadan. He was a Visiting Scholar at United Nations University – Institute for Natural Resources in Africa. Dr. Sowunmi specializes in Environmental Economics and Quantitative Techniques with many International Journal Publications to his credit.
Abstract:
Cocoa production in Ondo state, Nigeria over the years is accompanied by fungicides application to control black pod disease caused by Phytophthora megakarya, leading to adverse effect on the environment and cocoa output. Deviation in fungicides application from the standard recommended dose by farmers on cocoa output is common. Many studies on cocoa production often ignore such externalities. The study is aimed at determining the environmental efficiency of cocoa farmers by using detrimental variable (deviation in fungicide application form recommended dose) and traditional inputs in the context of stochastic frontier method.

Title: Effect of non-compostable contaminants on composting of organic municipal solid waste at different turning frequencies
Biography:
with the quality of compost derived from non-contaminated organic waste, and from non-sorted municipal waste containing a significant fraction of organic material. It was found that the maturation time of the composting process was longer for contaminated organic waste, but the quality of the compost was sufficient in all cases. In some conditions, positive effects on the compost quality were even observed.
Abstract:
The purpose of this study is to investigate the influence of plastics and metallic bottle caps as contaminants on composting and compost quality. 7% waste plastics and 2% bottle caps were deliberately added to sorted compostable waste as contaminants, and the compost quality was compared with the quality of compost derived from non-contaminated organic waste,
