تم إنشاء و تشغيل وحدة معالجة تجريبية لدراسة إمكانية معالجة المياه الملوثة معالجة بيولوجية عن طريق استخدام النمو المعلق و النمو الملتصق. تتألف الوحدة التجريبية من وحدة ترذيذ تؤمن ترطيب الحوامل البيولوجية، و توزيع المياه بشكل متجانس عليها بالإضافة إلى زيادة تركيز الأوكسجين المنحل في المياه، يليها مرشح زود بوسائط للنمو البيولوجي الملتصق. بلغت مساحة الحوامل m2 (13) تقريباً، و التي تم تنمية الغشاء البيولوجي عليها بحيث تقوم البكتيريا الموجودة في الغشاء بتفكيك المادة العضوية وصولاً إلى إرجاع النترات إلى نتريت ثم إلى غاز النتروجين. يلي المرشح حوض تهوية يؤمن معالجة المياه عن طريق النمو المعلق. تم تركيب أجزاء الوحدة و تشغيلها بالاعتماد على مياه الصرف الصحي المأخوذة من غرفة التفتيش الموجودة بالقرب من الوحدة السكنية رقم (18). بلغت الكفاءة الوسطية لإزالة الـ BOD5 69.4%، بينما بلغت الكفاءة الوسطية لإزالة شاردة النترات 34%. بينت النتائج أن استخدام هذا النظام يحسن من مواصفات المياه الملوثة .
A pilot unit was constructed and operated to study the ability of treating polluted water using biological treatment. The experimental unit consists of water sprayer unit that ensure wetting of the filtered media and distributing water in a homogenous manner as well as increasing the dissolved oxygen concentration in water. The sprayer unit is followed by a biological filter; the area of the filtered media was (13) m2. The developed biological film placed on the filtered media will dismantle the organic matter, which reduce nitrates to nitrite then to a nitrogen gas. The filter was connected to an aeration basin where the suspended growth was archived. The pilot unit was operated depending on the water was taking from a manhole nearby the residential unit number 18. The average efficiency of BOD5 removing was 69.4% and of nitrate, removing was 34%. The results showed that this system can improve water's characteristics.

The floatation unit technology is considered a more advanced methodology
than the sedimentation approach as it is more effective in separating most
contaminators regardless of its size no matter how small and tiny it was and
irrespective of the mi
nimal density difference between the water and most
contaminators. The sedimentation approach depends on using assisting
water that contains more dissolved air than the normal water under the
regular conditions and therefore, once the over saturated water (assisting
water) enters the container of the floatation unit filled with contaminated
water, small bubbles will formulate immediately sticking most of the
contaminators that exist in the contaminated water, whether small of big
leading to a reduction of its density and thereof floating on surface during a
short period of time. The floating sludge can be removed mechanically.
This research discusses the problem of drinking water shortage and
distribution instability in Salamyeh city due to the current crisis.
Salamyeh city dependents on Orontes River as a source for drinking
water through Hama water supply facility, wh
ich sufferes repeated
sabbotage attacks. As a result, an emergency measure was implemented
by depending on local water sources within the city, which are deep wells
that produce water of sulphuric nature.Three desalination plants were
provided to treat local sulphuric water producing suitable safe water, but
these plants production is way less than the city needs.
Biodiesel can be produced from pure fatty acids or from frying oil wastes. To
optimize biodiesel manufacturing, many reported studies have built simulation models
to quantify the relationship between operating conditions and process performance.
This Research presents a detailed study and practical design for the
construction, programming and implementation of the system to
receive SMS messages sent from a mobile phone or more to the
SIM card placed with in the circuit (GSM-MODULE) connected in
turn with a microcontroller which translates and shows this message
on the optical matrix.
Plastic and rubber products considered of being a great importance to humans, but
their residues and wastes are a real environmental disaster. They are dumped in fields,
streams and forests or buried in large landfills that pose a serious hazard th
at needs to work
on solve it in the best possible way.
On the other hand, the economic problems caused by the erosion of concrete cement
have made it the major problem of infrastructure in the industrialized countries. Over the
past three decades, this problem has reached alarming proportions, which led to high repair
costs, whether in concrete or in reinforcing steel, Especially acidic media due to concrete
permeability of acid rainwater, where these costs exceeded initial construction amounts in
some cases.
This paper deals with the recycling of used tires and some types of plastic waste to
be used in the preparation of insulating materials for water and heat at a low cost compared
to the insulation materials currently used in the construction process, in addition to the
preparation of floor tiles for internal and external use.
