Handbook-for-The-operation-of-Water-Treatment-Works
The term “water quality” describes the physical, chemical and microbiological characteristics of water. These properties collectively determine the overall water quality and the fitness of the water for a specific use. These properties are either intrinsic to the water or are the result of substances that are dissolved or suspended in the water. Water quality is only meaningful when evaluated in relation to the use of the water. The reason is that water of a certain quality may be fit for a specific use, but completely unfit for another use. For example, water that is fit for human consumption may not be fit as boiler feed water because the dissolved inorganic salts that are acceptable in drinking water, are not tolerated in boiler feed water, since they may precipitate and cause blockages in the boiler equipment. Water that is fit for domestic use (drinking water) must comply with specific requirements. The most important requirement is that it must be safe to drink.

Design Criteria For Sewers And Watermains
Introduction
We have written 'Design Criteria for Sewers and Watermains' manual for City of Toronto staff and consulting engineers. The purpose of this manual is to ensure there is consistency in our operations. Clients—that’s you—want to be instructed in the same way each time you come to us, regardless of which office you may visit. This manual will help ensure that the information provided by staff is the same in all offices.
This manual is written for City staff and consulting engineers working on capital improvement projects and for consulting engineers working for the development industry preparing engineering designs and drawings for private developments. It can also serve as a reference for third parties designing transit infrastructure, underground utilities, and any other works located within a city right-of-way, located in close proximity to City sewers and watermains. This manual takes you step by step through all the criteria you will need in the design of a sewer or watermain and the requirements for submission. If you are going to be preparing a servicing study or designing a sewer or watermain in the city of Toronto, this manual is for you. This manual is available in both print and online formats.

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.

Design Of Advanced Reverse Osmosis And Nanofiltration Membranes For Water Purification
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.
