Less than one percent of all the water on our planet is accessible and usable for domestic and industrial purposes. In view of the growing global population and increasing urbanization, it is therefore vital that we find new ways of using our limited resources of drinking water more sustainably and more efficiently and of using new technologies to make existing water resources potable. The same applies to the treatment of wastewater, as 80% of municipal sewage currently flows untreated into our rivers, lakes and seas.
Totally Integrated Automation Solutions for greater efficiency in Water Plants
The demand for reliable high quality wastewater purification at a low cost is increasing all round the world. This increases the demand for proper control. The state of art in instrumentation, control and automation of wastewater treatment systems is in rapid development these years (Photo 1).
- The process understanding is improving.
- Better sensors provide reliable and online data on key process
- Better actuators provide more flexible control handles
- New controllers, models and estimation techniques makes it possible to make good use of the information.
All this allows for a considerable increase in plant performance in terms of reduced energy costs, reduced use of chemicals and improved and more reliable effluent water quality. The aim is a better environment at a lower cost.
