Removal Of Heavy Metals From Aqueous Solutions Using Local Adsorbents, Moza S. Al-Sharyani

Theses

The recent rapid increase in industrialization activities contributed to most of aquatic pollution problems. Among aquatic pollutants, heavy metals, such as zinc, lead, cadmium, and copper have gained relatively more significance in view of their persistence and toxicity. Due to their health and toxicological effects, environmental agencies and authorities have set strict regulations to maintain the limit of heavy metals in wastewater below the maximum acceptable concentration levels.

The technical feasibility of using raw date pits and different activated carbons prepared from date pits by air and acid activation as low cost local adsorbents for the removal of different heavy …

Techno-Economic Evaluation Of Conventional And Membrane-Based Pretreatment Before Reverse Osmosis, Shamma Ahmed Rashid Al-Malek

Theses

In this thesis, a technological and economical comparison was conducted on both conventional and membrane based pre-treatment before reverse osmosis desalination. In order to produce high quality water at the design recovery ratio, reverse osmosis membranes should receive high quality feed water in terms of turbidity, suspended solids, and biological matters. Conventional pre-treatment schemes of media and cartridge filters after coagulation chambers have been used for years. Due to the poor performance and decline in reverse osmosis recovery, membrane based pre-treatment has emerged and has been under research and study in the recent years. Few conventional pre-treatment reverse osmosis plants …

Quantitative And Qualitative Assessment Of Groundwater Resources In Al-Khatim Area, Uae, Ahmed Khaled Othman

Theses

The UAE has achieved remarkable progress in transformation from separated small emirates to a modern union country with a high standard of living. The country is however, considered an extreme arid region.

In spite of these harsh conditions, The UAE government has encouraged plantation in towns, villages and country side. This has led to sharp increase in the agricultural sector particularly during the last three decades. As the irrigated land kept increasing, there was a deep concern about the water demand and the impact of agriculture activities on groundwater systems. Al-Khatim area is considered one of the most important agricultural …
