Fresh water treatment for every type of water.
Hardly any water is just like another – that is the reason why the fresh water treatment processes must be tailor-made i.e. designed specifically for every case. Two goals must be kept in mind - treatment of the water, so that it is suitable for human consumption and the removal of anthroprogenic materials. This includes the separation or removal of bacteria, viruses and parasites, also the removal of nitrates, pesticides and herbicides used in insect eradication. A number of proven fresh water treatment processes are available. By using examples of a number of specific and partial processes, we would like to demonstrate technical measurement solutions for fresh water treatment processes with Endress+Hauser technology.
Gas exchange
Gas exchange is a method to remove unwanted gases from water and the oxygen supply. The focus is normally on the removal of aggressive carbon dioxide (deacidification) or other odour or taste adding materials such as hydrogen sulphide. Volume measurement of the incoming water and air is required for control as the relationship of water to air has to be kept constant. To measure the volume of water, electromagnetic flow meters are customarily employed. Promag 50W is a measuring instrument developed especially for the water industry. Next to its high accuracy, typical with Electromagnetic Flow measurement, the instruments in the PROline Promag family are characterised by their safety functions - EPD electrode, tooling concept for measuring point documentation and instrument testing.
External flow measurement using ultrasonic measurement technology is being applied in drinking water treatment. Endress+Hauser is innovative here too. The new Prosonic Flow 90W with improved signal recognition and evaluation allows this measuring method to be used in synthetic, fiberglass reinforced pipes. Advantages of ultrasonic measurement are found in the flexibility of the system as well as the simple installation procedure which does not interrupt the process. In this way, the Prosonic Flow 90W line is also a favorite when used as a measuring instrument which is applied flexibly, e.g. for special inspection and accounting purposes. The potential for reducing operating costs with optimized parts, inventory control and standardization of models is a feature of this analysis technology. A uniform transmitter concept for all relevant quality parameters such as conductivity, oxygen, pH, turbidity and chlorine is not often available. For the user, this represents increased expenditures in operating, training and inventory control. A uniform transmitter concept covering all relevant parameters reduces these costs. Endress+Hauser‘s Liquisys M offers a uniform transmitter concept. Uniform, menu-guided operation, modular system, parameter-specific check functions and the ability to cover all relevant parameters with one uniform transmitter family in working efficiently and cost-effectively.
