In the 1990s water quality protection was underdeveloped in Central and Eastern Europe (CEE) compared to EU 15 countries in most indicators. After the CEE countries joined the EU, all of them started to invest significant amounts to implement the requirements of EU water policies in the field of waste water collection and treatment, where efficient use of resources was function of several factors. In Hungary, a new National Sewerage and Waste Water Treatment Strategy was elaborated, which predicted that during the subsequent decade, the amount of sludge produced at waste water treatment plants would increase significantly. Environmental impacts and economical deposition of the increased amount of sludge have not been investigated in the Strategy. The paper presents an investigation, which was carried out with the application of a newly developed GIS based decision support methodology to identify suitable agricultural areas for deposition of the predicted increased amount of sludge taking into consideration multi-criteria hydrological, environmental, technical, economic and societal conditions that are all important in regional water resources management. The investigation included the entire territory of Hungary. It was concluded that only 25% of the agglomerations indentified in the Strategy has actually enough agricultural land for sludge utilization or other word: placement. This fact influences the investment and upgrading programmes of the waste water treatment plants in the future.

Retaining of water resources quality is one of the global ecological problems of the modern time. The most promising direction in solving the problem of water resources protection is the reduction of negative environmental influence of waste water from production facilities by upgrading the existing water treatment technologies. To treat utility water, technical and rain water from site facilities of Transneft system entities, the specialists developed and approved standard technological diagrams, which are used in producing treatment facilities. The standard technological diagrams provide for all necessary stages of waste water treatment ensures the reduction of pollution level to normal values. However, during operation of treatment facilities it was established, that to ensure the required quality of waste water treatment with initially high levels of pollution, the new technological solutions are necessary. The author presents the results of scientific-research work, in the context of which the best affordable technologies were identified in the area of the treatment of waste water with increased content of pollutants and non-uniform ingress pattern. On the basis of the research results the technical solutions were developed for optimization of operation of existing waste water treatment facilities by means of using combined treatment of technical and rain waters and utility waste waters and applying bioreactor with movable bed – biochips. The use of bioreactor with movable bed allows the increase in the area of active surface, which facilitates increase and retention of biomass. Biochips are completely immersed into waste waters, and biofilm is formed on the entire volume of immersion area, facilitating retention of biomass and preventing formation of sediments. Due to mixing the floating device with biofilm constantly moves along the whole area of bioreactor, and, in doing so, speeds up biochemical processes and uniformity of treatment. The advantages of a bioreactor with movable bed – its active sludge durability against increased and changing pollutant concentrations, change of waste water temperature and simplicity of application – ensured the possibility of its use for blending utility waters, technical and rain waters.

Sanitation Systems

In the province of Yogyakarta in Java, district of Gunungkidul is considered to be one of the poorest areas in Indonesia. Here, water shortage greatly affects the population, especially during the dry season, which lasts from April to October. The peculiarity of Gunungkidul is that despite high rainfall of about 1,800 mm per year, the water supply of the population is not guaranteed. Because of the karstic underground, rainfall rapidly seeps into the ground without sufficient surface storage. The current situation of sanitation systems consist of pit latrines or pour flush toilets and results in an inadequate waste water treatment. Untreated liquids infiltrates into the ground, thus posing a significant threat to groundwater quality. Owing to this reasons mentioned above, an integrated water resources management (IWRM) was established in the district of Gunungkidul. The aim of the IWRM-Indonesia project was to develop adaptable and sustainable technologies for the supply of the population in the project area with water in sufficient quantity and quality as well as the improvement of the waste water treatment situation, which is the focus of the study presented herein.

The effluents present in the water resources leads unqualified for various domestic and irrigation purposes. The waste water treatment purely depends upon the volume of contaminants. The objective of the study was to gives a detailed discussion about the chemical methods and different types of QDs involved, examining their effluents removing efficiency, the selectivity and sensitive detection of various chemicals present in the contaminated water bodies.

The City

In this study the sustainability of integrated water resources management in Amsterdam has been reviewed using the City Blueprint approach. The City Blueprint® is a set of 24 dedicated indicators divided over eight categories, i.e., water security, water quality, drinking water, sanitation, infrastructure, climate robustness, biodiversity and attractiveness, and governance including public participation. In 2006 the various urban water-related services in Amsterdam were brought under one roof, culminating in the country's first water cycle company called Waternet. Waternet is responsible for surface water (rivers, canals, ditches and lakes), groundwater, stormwater, drinking water supply and waste water treatment. The city's unique water cycle approach has proved highly beneficial. Currently Amsterdam is the best performing city of the 30 cities assessed so far. This can be explained by: (1) a long-term vision and a multi-level water governance approach, (2) integration of water, energy and material flows (e.g., struvite production), (3) the entanglement between urban quality and water management, and (4) the transparent communication to and feed-back from customers, i.e., farmers and citizens. Surface water quality and biodiversity remain future challenges.

Alternative Water

Water is critical for all life on the planet. Rapid industrialization and urbanization has caused India to face a water crisis since it has only 4 percent of the world’s water resources. In order to resolve the crisis, India has to look for alternative water resources which may include rainwater harvesting, grey water and sewage reuse and desalination. Grey water is defined as waste water generated from the bathroom, laundry and kitchens. Nearly 70 percent of the water used in households results in grey water which can be treated using simple technology and reused. Reuse of grey water reduces the fresh water requirements and reduces the amount of sewage sent to treatment plants. An integrated approach is needed to manage the water and waste water treatment so that water supply is kept clean and waste water is recycled for beneficial use in agriculture and industry. Water and energy are important resources in the 21st century. Water is required to supply energy, and energy is required to supply water. The reclamation of wastewater can contribute significantly to the conservation of water and energy resources. Wastewater reclamation and reuse can relieve water scarcity. Reclaimed wastewater can be substituted for natural water. Wastewater is now extensively recognized as an important source of water in water-scarce countries. In recent years not only the threats of improper greywater management have been recognized; there is an increasing international recognition that greywater reuse, if properly done, has a great potential as alternative water source for purposes such as irrigation, toilet flushing, car washing and others.
