  * Water Pollution Research department, National Research Centre, Cairo, Egypt **Faculty of Engineering, Cairo University, Cairo, Egypt Abstract Treatment of chemical industrial wastewater from building and construction chemicals factory and plastic shoes manufacturing factory was investigated. The two factories discharge their wastewater into the public sewerage network. The results showed the wastewater discharged from…

  ABSTRACT An oil refinery normally uses large quantities of water, for cooling and other process purpose. This water is treated from contaminants and finally returned to a lake or sea, outside the refinery. Amerya Petroleum Refining Company (APRC) uses conventional and special treatment methods for wastewater to remove all pollutants and to reduce the…

Modeling of Hybrid Growth Wastewater Bio-reactor Abstract The attached/suspended growth mixed reactors are considered one of the recently tried approaches to improve the performance of the biological treatment by increasing the volume of the accumulated biomass in terms of attached growth as well as suspended growth. Moreover, the domestic WW can be easily mixed with…

Pollution of lake Mariut Abstract Lake Mariut, south Alexandria, Egypt suffered in the recent decades from intensive pollution as a result of a continuous discharge of huge amounts of agriculture wastewater that contains a large concentration of the washed pesticides and fertilizers in addition to domestic and industrial untreated wastewater. The over flow from the…

  Suitability of using duckweed as feed and treated sewage as ABSTRACT Use of treated effluent and duckweed biomass from a pilot-scale UASBduckweed ponds system treating domestic sewage was evaluated in rearing Nile tilapia (Oreochromis niloticus). Nutritional value of duckweed as sole feed was compared with wheat bran. Two sources of water were used for…

Novel Autothermal Reforming Process for Pure Hydrogen Produc ABSTRACT Steam reforming of heptane for hydrogen production is investigated in a novel Circulating Fluidized Bed Membrane Reformer-Regenerator system (CFBMRR) utilizing a number of hydrogen and oxygen selective membranes. It is shown that although the amount of carbon deposition is significant, the effect on catalyst deactivation is…

  Oxidative Dehydrogenation of Methanol on Chromium Oxide-Mont ABSTRACT Methanol conversion was carried out on one of mesoporous materials, Chromia / Montmorillonite K10 (MK10) in a pulse microcatalytic system. Methanol was converted to formaldehyde and ethylene by two different mechanisms. Methanol dehydrogenation increases by reaction temperature (300-400oC) and as chromia loading decrease. In contradiction, the…

Reuse of Hydrotreating Spent Catalyst ABSTRACT All hydro treating catalysts used in petroleum refining processes gradually lose activity through coking, poisoning by metal, sulfur or halides or lose surface area from sintering at high process temperatures. Waste hydrotreating catalyst, which have been used in re-refining of waste lube oil at Alexandria Petroleum Company (after 5…

A New Process for Co-Production of Ammonia & Methanol Abstract: A new process for co-production of ammonia and methanol is proposed. The process involves the production of synthesis gas by oxygen blown autothermal reformer (ATR) at a pressure of 40-100 bars, a methanol synthesis loop at a pressure of 50-100 bars and an ammonia synthesi…
