TECHNICAL BACKGROUND

Water is the source of life, without which human beings can not live. Due to global warming, the increasing population in the world, the development of industry and the environmental pollution, potable water resource is running out and there is a ‘water crisis’ in the world.

Water in our daily life is supplied in this way: the tap water plant purifies the source water and through supply pipe transfers the tap water to pressure-regulating tower to supply water, from where tap water is allocated to water-supply pipe network in residency areas for daily use of the residents. When the pressure regulating tower for water-supply pressures the tap water and supplies to every unit, the water-supply pipe network may contaminate the tap water for the second time. In recent years with the development of world economy, human beings pay more attention to and have higher requirement of the sanitation and environment. People want to have drinkable water of high quality. As a result, domestic water filter, bottled water and electrolyzed purified water appear in the market. But these water products are expensive and difficult to use so that only a small number of families use them, while most people can not. The domestic water filter is easy to be blocked and hard to clean.

In our new water-supply system with pressure regulation for drinkable, service water, the water plant does not directly supply drinkable water at the initiating terminal after routine processing but delivers domestic water to the ending terminal while the forestage of our system, where drinkable, service water with desired standard is supplied to users after further processing. If the resource water or the water at the initiating terminal was polluted, the processing at the ending terminal while the forestage of our system could be a temporary solution against pollution.

Central processing of water for different quality as drinkable, service water can solve the problem of safety and sanitation of drinkable water for human and livestock in towns and remote rural mountainous areas with scattered population in the world. Because central processing of water for different quality as drinkable, service and recycled water can provide safe and sanitary water, develop water-supply system further and economically, it will be more popular. Economical exploitation and using water resource is for all living human and benefits economic development and health of human.
