The sanitary quality of drinking water poses a fundamental challenge throughout the world. Sanitary quality encompasses not only bacteriological aspects but also the need to control by-products resulting from treatment processes or chemicals used.
Available reserves of natural water are ground water, standing or running surface water, and sea water. Choosing what water will be treated before delivery depends on the quantity of available water, its quality (taking into account the possible variations), investment costs and the cost of the procedures that must be implemented to ensure that the water will be suitable for drinking. In some regions of the world, fresh water is so scarce that treatment processes must use as little water as possible.
We design treatment systems that range from the traditional to the more sophisticated, such as membrane-based systems, and offer local authorities technical solutions that meet their sanitary quality requirements, whether for a village of several hundred inhabitants or a major urban area. Making water potable typically involves several treatment stages and a variety of technologies:
- Specific treatment to reduce iron, manganese and arsenic or to thoroughly remove dissolved organic matter and micro-pollutants;
- Complete treatment from coagulation to disinfection in a package unit.
