Radiation-Thermal Purification of Wastewater from Oil Pollution

I. Mustafayev; R. Rzayev; N. Guliyeva

The results of study oxygen's influence on the radiation-thermal decomposition of n-heptane admixtures in water medium are adduced. The main parameters of radiolysis were changed within the limits: temperature 20–400℃, absorbed dose-0÷16.0 kGy at dose rate 3.2 kGy/h. As a product of decomposition are observed H, CO, CH, CH, CH, CH, CH, CH, hydrocarbons C-C. The changes of n-heptane concentration in the reactor also are established. The increasing of n-heptane decomposition rate and decreasing of gas formation rate in presence of O are observed. As a result of summarizing of experimental data, the kinetic model of processes has been proposed.

Analysis of Antibiotic Resistance Patterns of Fecal in Coastal Waters of Puerto Rico

Nydia J. Rodríguez; Baqar R. Zaidi

Multiple antibiotics resistance of species was compared in Guánica, Guayanilla, and Mayagüez coastal water. Only 10, 12, and 12% of respectively were resistant to chlortetracycline at 10 μg/ml and less than 5% were resistant at 50 μg/ml. However, in Barceloneta coastal water 48% and 28% of were resistant to chlortetracycline at 10 and 50 μg/ml respectively. Similar results were obtained using oxytetracycline and salinomycin. Numbers of species resistance to multiple antibiotics were highest in Barceloneta and lowest in Guánica coastal water. Results of multiple antibiotic resistances in Barceloneta River, estuary, and coastal water are presented.

Effects of Wastewater Irrigation on Chemical, Microbiological and Virological Status of Soil

Filip Zdenek; Katherina Demnerova

A long-term wastewater irrigation on soil composed of glacial sand resulted in the transformation of the soil profile, which included chemical, microbiological, biochemical, and virological soil characteristics. The individual soil samples contained organic particles by weight, but these particles represented an important storage of nutrient and energy for microorganisms. The wastewater irrigation on a sandy soil resulted in positive effects on soil activities, and did not create any risk through pathogenic bacteria or viruses to a local deep groundwater aquifer.

Risk Assessment on Population Health

A. Bayramov

The toxicology of a human environment is based on the assumption that toxicity of pollutants is directly proportional to their concentration (in wastewater, in aerosphere, and in soil). The calculation method of probability of effect (risk) of toxic pollutants action on the population health is described. The algorithm of risk assessment of pollution impact on a population health is considered. The risk factor (coefficient of a ratio of risk increase) is a function of concentration of toxic substances in an environment: atmosphere, wastewater, soil.

Thermal Treatment of Wastewater from Cheese Production in Turkey

Lutz B. Giese; Alper Baba; Asaf Pekdeger

During the last years, several cheese factories had been established in western Anatolia. Due to this positive industrial development, pollution from wastewater discharge has threatened the local environment. On the other hand, this area especially owns a significant renewable energy potential and thereby geothermal energy. These environmentally sound sources are to be applied in thermal wastewater treatment process.

Environmental Aspects of Wastewater Reuse

Mohammed K. Zaidi

Wastewater has a high potential for reuse in agriculture, especially in arid and semiarid areas. Wastewater reuse increases food production by providing a stable supply of water, and contributes to environmental security by reducing the pollution level of rivers and surface water. It also conserves a significant portion of river basin waters and allows for the disposal of municipal wastewater in a low-cost, sanitary way. A very small percentage of wastewater is currently being used for irrigation in the world. Wastewater collection, its treatment, disposal of waste, and use of treated wastewater is a big challenge to environmental security. This paper discusses the latest research developments in the field of wastewater reuse and the factors affecting environmental security.

Wastewater Reuse in Israel and in the West Bank

Sarit Shalhevet

Improved wastewater treatment in the Israel and in the West Bank is an important step towards resolving the existing problems of water shortage and pollution in the region. This will enable to increase water availability and quality in the West Bank villages, thereby increasing the social, economic, and environmental sustain ability as well as decreasing the environmental threat of pollution of the groundwater resources. This paper examines different scenarios of water supply, demand, and allocation arrangements in order to reach the optimal decisions on wastewater treatment, based on principles of sustainable development.

Wastewater Management in Egypt

Hussein I. Abdel-Shafy; Raouf O. Aly

The present work aims at highlighting the challenge encountering the environmental management of wastewater in Egypt. In addition, water consumption, industrial, domestic and agricultural pollution, and their adverse impact on water quality is discussed. The weak regularity in compliance and enforcement of the environmental legislation is evaluated. The industrial pollution is at alarming degree.

Health Assessment of Wastewater Reuse in Jordan

Mu'taz Al-Alawi

Irrigation with low quality of treated wastewater in the Jordan Valley has been practiced for several decades. The present study was designed to determine the health effects of this practice on the transmission of two protozoan infections, giardiasis and amoebiasis. Results of this study showed that at the exposed group 73% of the subjects were infected by Giardia and/or , and only 24% in the control zone. This excess of parasitic infestation may be related to the low quality of wastewater reuse in agriculture.

Wastewater Risk Assessment of Polyester Cabins in Egypt

Mohamed A. Amasha; Tarek M. Abou Elmaaty

The technological revolution has brought a great progress in furniture industry which considered as one of the most vital resources in Egypt economy. The government has established a great number of polyester cabins (in Damietta governorate) which used in furniture painting and varnishing. The wastewater is transferred by the same route to the water purification station which according to our research has no proper means to eliminate the polyester hazard. In this work we conducted a survey among the cabin workers to assist their knowledge about the wastewater hazard. Also, we have suggested a strategy to overcome this problem.
