Design Criteria Of The Oxidation Ponds In Egypt And World Wide
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.

Good Practice Guide to the Operation of Drinking Water Supply Systems for the Management of Microbial Risk
INTRODUCTION
Purpose of Good Practice Guide The catchment-to-consumer risk-based approach to the production of microbially-safe drinking water, which is detailed in the Framework for Management of Drinking Water Quality (the Framework) that underpins the Australian Drinking Water Guidelines (ADWG), is based on the identification and control of risks to the quality of drinking water supplied to consumers. This reduction in risk is achieved by implementing a multiple barrier approach, where a number of different barriers to contamination are put in place, from the catchment to the consumer. Whilst the risk management
process stretches all the way from catchment to consumer, in practice the majority of risks are managed through the use of various water treatment processes. Most Australian source waters require some level of treatment prior to being supplied to consumersas drinking water. The level of treatment required to produce microbially-safe drinking water will be a function of the quality of the source water and should be informed by a system-specific risk
assessment process that is consistent with the approach described under Element 2 (Assessment of the drinking water supply system) of the Framework.
The production of microbially-safe drinking water is difficult to consistently achieve, and requires constant vigilance, as well as well-maintained and operated water treatment processes (Element 3 (Preventive measures for drinking water quality management) and Element 4 (Operational procedures
and process control) of the Framework). Within this risk-based approach, the purpose of this Guide is to provide concise advice on good practice preventive measures for the management of drinking water treatment processes and the distribution of this treated water to consumers. This is achieved by providing targets, both numerical and observational, for the various activities that should be undertaken in order to produce microbiallysafe drinking water.
The Guide is not intended to be a risk assessment tool; it assumes that a system-specific risk assessment has been done, and that the treatment and distribution processes that are present are suitable for the assessed level of microbial risk. The Guide is therefore focused on the optimisation,
management and control of existing water supply systems. The advice in this Guide is applicable to existing water supply systems and is intended to help water utilities produce microbially-safe drinking water under existing arrangements; it will also assist utilities meet any future microbial health-based targets that may be includes in the ADWG. The Guide is presented in a tabular format for simplicity. The table is broken into sections that relate
to the key control points in typical water treatment and distribution systems.

Water Treatment Continuing Education Professional Development Course
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).
