Statistical Analysis For Water Quality Data Using Anova (Case Study- Lake Burullus Influent Drains), Mohamed Hussein Hegazy

Civil Engineering

Lake Burullus is considered one of the most valuable northern lakes in Egypt due to its unique ecological system and special location. Over the past four decades, the lake has suffered from high contamination levels due to expansion in fish farming and increasing of agricultural drainage water entering the southern side of the lake through eight influent drains. This research aims to assess the current situation of the lake’s influent drains. For this purpose, two types of statistical analysis, Mean average method, and Analysis of Variance (ANOVA) were used. The water quality conditions for six major drains (Therah (Tira), Nashart, …

The Neighborhood As An Energy-Generating Community The Case Of El-Banafseg Residential Neighborhood, East Cairo, Amany G. Micheal Prof., Mona Helmy Dr.

Centre for Advanced Materials

Nowadays, energy consumption is a global challenge. This is due to the shortage of several energy sources, and consequently, to their increasing prices. This paper argues that by using an integrative approach for using various energy harvesting techniques, a typical residential neighborhood can be operated as a self-generator of its needed energy, or part of it.

The paper follows a mixed qualitative, experimental, and numerical simulation approaches to examine the practicality of the paper hypothesis. It uses Space syntax modeling theory (a socio-spatial software) to analyze the pedestrian flow to indicate the potential locations of the kinetic energy harvesting Piezoelectric …

Properties Of Cement Mortar Containing Recycled High-Density Polyethylene (Hdpe), Amany G. Micheal Prof., Esraa Torky, Merna Amir

Centre for Advanced Materials

Millions of tones of plastic waste are generated globally and only less than 10 per cent has been recycled. It is crucial to segregate and circulate plastic waste and repurposing it for countless other uses. There are many ways to repurpose and reuse these discarded plastics. One use that can be examined is the use of plastic as partial sand replacement in mortar. To contribute to this important and valid discourse, the research studies the mechanical and thermal properties of recycled HDPE mortar as an active way of integrating plastic waste into the construction industry to partially eliminate some of …

Implementation Of Secondary And Tertiary Treated Wastewater In Concrete Manufacturing, Amany G. Micheal Prof., Haidy Abdel Salam, Gouda Ghanem

Civil Engineering

Water scarcity is a problem that faces many regions. In a developing and arid country like Egypt, the need for freshwater is exponentially increasing. This research is an evaluation of the recycled wastewater to be used in concrete manufacturing. The treated wastewater is blended with potable water with percentages of 25%, 50%, and 100%. The mixture of the two types of water is used in concrete mixing and curing. Control specimens with pure potable water are cast for comparison. The setting time for Ordinary Portland Cement is tested using the different water mixes. The hardened concrete is tested in compression …

Causes Influencing Construction Waste Generation During The Design Process: An Analytical Study, Aya Saad, Ayman Ahmed Ezzat Othman

Architectural Engineering

Despite the social and economic contributions of the construction industry towards achieving sustainable development objectives, it has an adverse effect on the environment such as the generation of waste, water, and energy consumption. Construction waste (CW) is the loss of materials that are produced during or after the construction process and has no remaining value. Several countries promote waste elimination plans at early stages to reduce CW at its source. The Egyptian government is expanding its investments in new mega projects and infrastructure facilities like new administrative capital, bridges, roads, energy projects which resulted in increasing the rate and amount …

Isotherm And Kinetics Study For The Adsorption Of Nitrate From An Aqueous Solution Using A Modified Rice Straw, Dalia A. Ali Eng, Mohamed A. Sadek Prof., Nagwa Mahmoud Al-Mansi Prof, Ahmad Wafiq Aboelnasr Dr.

Chemical Engineering

In this research, modified rice straw (MRS) is proposed. The proposed production process of the modified rice straw (MRS) adsorbent is carried out by precipitation of iron nano particles on the surface of acid activated rice straw. The nitrate adsorption is carried out through batch experiments. The optimum nitrate removal 94.8 % was achieved at pH = 7, adsorbent dose 3 = g/L, 150 rpm, initial nitrate concentration = 23 mg/L and contact time 180 = min. The new adsorbent synthesis, kinetics and isotherm models were studied. The nitrate adsorption was well described by pseudo second order kinetic model (R2 …

Optimization Of Nitrate Removal From Aqueous Solution By Acid-Activated Rice Straw Supported Nano Zero-Valent Iron Using Response Surface Methodology, Dalia A. Ali Eng, Nagwa Mahmoud Al-Mansi Prof, Mohamed Amin Sadek Prof., Ahmad Wafiq Abolnasr Dr.

Chemical Engineering

Rice straw is one of the most common agricultural wastes due to its large production amounts. Energy valorization of rice straw is a technology used for nitrate removal as the produced ashes used to generate the adsorbent by means of an alkali dissolution followed by acid precipitation. The novelty of the proposed process is that the production of the nano zero-valent iron supported acid-activated rice straw (AARS-nZVI) adsorbent is carried out without the energy valorization process but, through an acid activation for rice straw followed by precipitation of nZVI particles on its surface. The new adsorbent synthesis, characterization and application …

Investigating The Experimental Process For Partial Replacement Of Cement With Sugarcane Bagasse In The Construction Industry, Amany G. Micheal Prof., Rania Moussa, Nadin Dawoud

Centre for Advanced Materials

In the last few decades there has been speedily increasing in the agriculture and industrial wastes. This causes many environmental issues and raises the potential to contaminate the natural resources of living such as water, air and soil. Recently, the amount of organic waste produced daily has been rising, while it is poorly managed. It is either burned or disposed improperly, which effect negatively the environment and public health. On the other hand, during the cement production process many wastes, and pollutants are generated which have major negative impacts on the environment. Cement is considered as a substantial constituent of …

An Investigation Into Solid Waste Problem In The Egyptian Construction Industry: A Mini-Review, Ahmed Osama Daoud, Ayman Ahmed Ezzat Othman, Herbert Robinson, Ali Bayyati

Architectural Engineering

Solid waste management (SWM) is one of the most critical global challenges nowadays. It has a severe negative effect on the triple bottom line of sustainability. Construction and demolition waste (CDW) contributes about 50% of the total global annual generated SW. In the particular case of the Middle East and North Africa (MENA) region including Egypt, the SW problem has become a major challenge, and the need to find sustainable solutions is overwhelming. However, the region faces several challenges that hinder the development of an effective and efficient SWM system. This has resulted in the predominance of unsustainable SWM practices …
