ABSTRACT "Design Criteria of the oxidation ponds in Egypt and world wide" Oxidation ponds, known as waste stabilization ponds, have become one of the world’s most used methods of treating waste water in areas where there is large space for their construction. In addition, they are one of the most economical and environmentally friendly ways of treating wastewater and producing a highly purified effluent. They create a natural environment and utilize natural processes to treat wastewater contaminants and can include other systems such as constructed wetlands, septic tanks, lagoons and others. In this research present how to access to the best ways to design different oxidation ponds that are consistent with the Egyptian conditions of temperature, wind direction, the amount of treated water and study the nature of groundwater, soil characteristics and components, and the sun shining, the characteristics of the wastewater ponds, suitable form of ponds and method of operation optimization, construction and operating costs and the price of land, the fields of use of treated water and taking into account the characteristics of wastewater in Egypt, and which can be known by COD, BOD, TSS of the water where the properties of wastewater in Egypt is different from the rest of the world and present the principal considerations are taken during the design.

ABSTRACT: Most commercially available reverse osmosis (RO) and nanofiltration (NF) membranes are based on the thin film composite (TFC) aromatic polyamide membranes. However, they have several disadvantages including low resistance to fouling, low chemical and thermal stabilities and limited chlorine tolerance. To address these problems, advanced RO/NF membranes are being developed from polyimides for water and wastewater treatments. The following three projects have resulted from my research.

Water Treatment CEU Training Course Water Distribution, Well Drillers, Pump Installers, Water Treatment Operators. The target audience for this course is anyone interested in working in a water treatment or distribution facility, wishing to maintain CEUs for a certification license, learn how to do the job safely and effectively and/or to meet education needs for promotion. This short CEU course will cover the fundamentals of water treatment beginning with the source of water and ending with the disinfection and distribution, making sure it meets federal compliance. Task Analysis and Training Needs Assessments have been conducted to determine or set Needs-To-Know for this course. The following is a listing of some of those who have conducted extensive valid studies from which TLC has based this program upon: the Environmental Protection Agency (EPA), the Arizona Department of Environmental Quality (ADEQ), the Texas Commission of Environmental Quality (TCEQ) and the American Boards of Certification (ABC).
