6 Comment

Water is the most vital resWater Treatmentource & raw material of the 21st century. Only about 3 % of the water on our planet is fresh & of these just 10 % can be exploited economically.  It is estimated that 1.1 billion people lack access to clean drinking water and there is a water shortage in already 30 countries. Thus a secure water supply is regarded as one of the most important global objectives for the coming years. Without the use of the latest technology, a secure drinking water supply is impossible. Innovative technologies for the treatment of drinking water as well as water reuse are becoming a subject of global significance. Water is an important production factor. The spectrum of industrial water ranges from cooling and boiler feed, water in power stations and process, water for a wide range of industrial uses to ultra pure water for the electronics and pharmaceutical industries. In view of the limited availability of water and the necessity of conserving existing reserves, the use of water recycling is gaining importance. Recycling increases the water availability for private, commercial, agricultural and industrial needs.

A growing population has increased the demand for drinking water and rapid urbanization has required increasing sewage treatment.

Growing public concern, media pressure and renewed legislation has left industries with no option but to install water treatment equipment. The water treatment companies offer sustainable solutions that serve as the economic basis for a region and provide enhanced quality of life for people. They aim at the conservation and ecological utilization of water. However, Indian companies have limited capabilities and technology for the design of water treatment plants. There is a distinct opportunity for U.S. companies to offer technical consulting.
