Wastewater treatment is the process of removing contaminants from wastewater and household sewage, both runoff (effluents) and domestic. It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce a waste stream (or treated effluent) and a solid waste or sludge suitable for discharge or reuse back into the environment. This material is often inadvertently contaminated with many toxic organic and inorganic compounds. Solar energy is quite simply the energy produced directly by the sun and collected elsewhere, normally the Earth. The sun creates its energy through a thermonuclear process that converts about 650,000,0001 tons of hydrogen to helium every second. The process creates heat and electromagnetic radiation. The heat remains in the sun and is instrumental in maintaining the thermonuclear reaction. The electromagnetic radiation (including visible light, infra-red light, and ultra-violet radiation) streams out into space in all directions. A solar still operates on the same principle as rainwater: evaporation and condensation. The water from the oceans evaporates, only to cool, condense, and return to earth as rain. When the water evaporates, it removes only pure water and leaves all contaminants behind. Solar stills mimic this natural process . Solar still has a top cover made of glass, with an interior surface made of a waterproof membrane. This interior surface uses a blackened material to improve absorption of the sun's rays. Parabolic trough technology is used to produce heat to replace conventional energy used to heat water and air, to generate steam and to produce air-conditioning.Below is an explanation of the concept of parabolic trough solar collectors, factors that influence their design and the practicality and usefulness of the technology to meet a wide range of energy requirements. The parts of the trough system and its working: • The parabolic trough reflector: The cylindrical parabolic reflector reflects incident sunlight from its surface onto the receiver at the focus point. Typically, the reflector is made of thick glass silver mirrors formed into the shape of a parabola. Alternatively, mirrors can be made from thin glass, plastic films or polished metals. • The receiver tube or heat collection element: The receiver tube consists of a metal absorber surrounded by a glass envelope. The absorber is coated with a selective coating to maximize energy collection and to minimize heat loss. The glass envelope is used to insulate the absorber from heat loss, and is typically coated with an anti-reflective surface to increase the transmittance of light through the glass to the absorber. For high temperature CSP applications, the space between the absorber and glass tube is evacuated to form a vacuum

In this study the possibility of using waste heat to operate a small size air cooling device was investigated. Such devices are proposed to be used in automobile air conditioning systems that utilize either the rejected heat from the exhaust gases or the engine cooling water. Two different alternatives of heat exchanger types was proposed, they are: air-water system, and water-water system. The last type was used due to small surface areas. The designed absorption Refrigeration cycle uses LiBr2-watre pair as the working fluid. The proposed device was designed and constructed successfully using the proper metals. The main components were: evaporator, generator, condenser, absorber, and tow expansion valves. Many difficulties were faced during the operation of the device as result of the operating conditions since such cooling systems working pressure is 91 kPa vacuums. It was difficult to operate the cycle continually due the failure of the used pump under deep vacuum pressure. As a result the cycle was operated discontinuously and a 2oC temperature drop in the cooled water was observed for a single cycle operation for cold water flow rate of 0.0254 kg/s. It was concluded that such cooling device needs special type of throttling valves that work under very small pressure drop and vacuum conditions. Moreover the locations of the input and output lines from each component should be selected carefully to sure good self regulating level control of the liquid.

The bread industry has since ancient times, it can not dispense with the bread, is the most

important source of food , the bread industry has evolved, and started making bread by putting

metal flat plate on the fire and then putting dough above it, It then became a profession .

There are two types of bakeries, semi-automatic and full- automatic, by semi-automatic

bakeries each process separate from the other as the mixture process is making without respect to

other as well as cutter, rounder and etc, on the other hand, by full-automatic bakeries each

process is making with respect to other by sensors system.

A bakery consists of several parts (Dough mixing, Cutting, Rounding, Rolling and

Baking). In our project we focus only on the design on an oven for baking of bread.

This oven will be dedicated for Arab bread of a diameter of 15 cm to accommodate 14

loaves which must stay in the oven for a period ranging from 60 seconds to 80 second, at a






=7854 kg/m³

We chose bread oven project because of two reasons:

1) Bread ovens in the Palestinian market was manufactured by blacksmiths who do not

have the scientific skills in engineering design and production, which may be one reason for the

poor in thermal efficiency of the furnace, which reduces the profits to the owners of these ovens

and bread prices becomes more and more. For this reason we decide to make the development of

our society that increase the Palestinian furnace efficiency to save the energy and increase the

profits of ovens owners.

2) Palestinian countryside of Palestinian society used to make bread by primitive methods

and the kind of hardship, they plant wheat fields for this purpose, in our oven we will decrease

the size and material used to achieve a cheep family oven which withstand the need of the

Palestinian villages homes, small markets and restaurants, This furnace produces 81.3 kg of

bread in one hour

Palestine is considered a poor country in the sources of fossil fuel (power), nowadays this fossil power prices are escalating to unprecedented levels, which is not affordable by our economy especially that the demand on this type of power is increasing, in other words the prices of oil is expected to go higher & higher…….. which our citizens can not withstand ,



As long as Palestine is a sunny country, the most suitable solution for our poverty in fossil fuel is to look for the means that allow us to utilize the free power of the sun. Upon the studies conducted on solar power it is noticed how huge is the quantity of unutilized solar power, as a result of our negligence to this vital & free source of power. Compared to the other projects which were built to utilize the solar power, our project is:-





1. Applicable: it is easy to manufacture, the raw material used to fabricate it is

available & it needs no operators.





2. Efficient: the incident rays of the sun remain perpendicular on the plate (panel) all the day over, which actually means that the output power is the highest attained.





3. Low running cost: because the operation cost is merely negligible.





For the above mentioned justifications we believe that our project is practical & cheap. We hope that the university will adopt it one of the leading projects that its students have created.

DESIGN_OF_MEDICAL_WASTE_INCINERTOR_INTEGRATED_WITH _DEASINLATION.doc

In Palestine Medical waste is one of the most important environmental problems that are facing Palestinian national authority (PNA) in the last few years.



The disposal of garbage and medical waste is a problem that continues to grow with the development of industrialized nations and the growth of population. Since the beginning of the people have needed to find a way of disposing of the trash. In 18th century England and France, carters were paid by individuals to carry trash and discard it on the outskirts of town. Disposal in open pits became routine and Benjamin Franklin initiated the first municipal cleaning program in Philadelphia in 1757. Since then we have come a long way and have developed types of waste that cannot simply be dumped into a hole.



The purpose of this study was first, to study the construction of incinerator integrated with distillation water for Nablus city. Second, increase awareness about Mechanical and thermal design.



The results of the study reveal that:

1. The total Quantities product from Nablus hospitals approximately 810Kg/day.

2. There is no heat recovery system attached with medical incinerators in Palestine.

3. The study also shows that the heat product from the medical incinerator can be used to produce distillate water at flow rate of 900kg/hr
