Design and Development of Innovative Highland water filtration System

World Journal of Engineering and Technology 2016年第3期4卷 383-390页

作者： Mohd Hudzari Razali Syazili Roslan Abdus Ssomad M. Abd Halim Ahmad Farizal Md. Shokeri Nur Azuan Husin Faculty of Bioresources & Food Industry Universiti Sultan Zainal Abidin Tembila Campus Malaysia

The righteous book of Al-Quran mentions that the basic need of the living thing in this world is water. Resident of rural areas such as indigenous people will tap the highland aquatic resources as the main foundation for water. The reservoir is built on the top of hilly area to collect water before it discharges through a pipe system that uses the force of gravity to go down to the settlements. However, the filtration system frequently clogs and requires the occupants to climb up the reservoir hill for cleaning process. A lot of energy and time are required to manage the irrigation systems. Thus, an innovation system has been conducted as the filters will be cleaned automatically using solar energy supply. The designs of the filters are specially designed as the filter is equipped with electric motors, washer rods, power supply units, and automatic control box. The advantages of this project are the product will filtered the water as remain as natural highland watering resources while using the solar energy to accomplished green technology application.

Corrosion Processes in the Concrete of the Dams

Journal of Civil Engineering and Architecture 2013年第4期7卷 414-421页

作者： Mark A. Sadovich Tatyana F. Shlyakhtina M. Kuritsyna Department of Technology Bratsk State University Bratsk 665 709 Russia

During the whole operation life of Bratsk and Ust-Ilimsk hydroelectric plants, chemical analysis of water filtering through the pressure front of the concrete dams was under systematic monitoring by sampling in places of concemrated outcome in the inspection galleries of a dam. Long-term cumulative observations made up a basis for study of the indicated dams concrete corrosion caused by the Angara water in the process of its filtration through the cracks formed in the period of the dam erection, through construction joims and other defects. Mathematical-statistical analysis allowed the classification the processes of corrosion from the point of view of their time dynamics and divided them correspondingly into stationary （stable） and non-stationary. On the basis of a calculation of the cement stone componem removal along with the ideas of the process dynamics the pressure from filtration developmem forecast has been made and their danger level has been estimated. The developed conception is of rather a general character and can be used when analyzing the state of concrete dams of the Angara cascade and other similar cases.
