Clean water for Mozambique

April 2009 Fieldbus & Industrial Networking

Cost-effective wastewater management comes naturally with Endress+Hauser.

Increasing industrialisation and population growth has caused tremendous contamination of surface waters during the last decades. Consequently, the laws regarding environmental protection have been tightened in many countries. To fulfil these regulations means increasing the number and the efficiency of wastewater treatment plants.

Not surprisingly, the driving factor in today’s investment in wastewater treatment is cost reduction. The only way to maintain high standards while reducing costs is to invest in highly sophisticated measurement and control technology, ideally from a supplier offering the whole basket of instruments.

From integration to automation

With the introduction of communication technologies like Hart, Profibus and Foundation fieldbus, the barriers between field instrumentation and the system level began to disappear. The instruments became more intelligent and an integral part of the automation architecture.

Endress+Hauser recognised this development at an early stage and became actively involved in different standardising bodies and user organisations since the inception of fieldbus technology. In this way the company has ensured that its customers stay in touch with new trends.

Wastewater treatment not only includes operating, supervising, servicing and repairing equipment, it also involves the key topics of operation flow, monitoring and controlling, measuring, analysing, recording and evaluating.

Therefore, a fieldbus connection offers much more than a process variable from a field instrument. Instrument status, maintenance and diagnostic information are available to be transferred from the process to the control room. This information makes it possible to increase the availability of the plant and to optimise processes. E+H ensure the integration of this information into the system environment.

To this end, the company supports both technologies that are established in the market as well as the new FDT integration technology for Plan Asset Management. FieldCare is a Plant Asset Management solution offering commissioning, condition monitoring and access to diagnostic information from the digital process instruments.

In addition, E+H says it offers comprehensive engineering services for the integration of field instruments into all relevant control and asset management systems in the process industry. Field instruments are the source of the information to be measured in order to perform wastewater treatment. E+H keeps processes running by monitoring complications due to inlet water flow and pollutant variations while helping to maintain effluent standards.

Electromagnetic flowmeters also play a very important role in wastewater management. Over the past 31 years, E+H has become one of the world’s leading producers of electromagnetic flowmeters. Last year the company celebrated the sale of its millionth flowmeter by supporting a water project in Mozambique undertaken by development organisation Helvetas. The project emphasised the fact that there are more than a billion people in the world who still have no access to clean drinking water. This stark reality reminds that there is a limited amount of natural, clean water available, making proper treatment of this life sustaining resource a necessity.

A range of services to suit all needs

* Optimised processes with an analysis of the installed base.

Operators of industrial plants find themselves increasingly under pressure to reduce costs. Optimal performance of measurement processes is essential to plant availability and product safety.

* Instrument management solutions (IMS).

IMS is an efficient, cost-effective process that optimises the installed base. The advantages include increased plant up time, emergency planning and the quick availability of spare parts.

* Preventive maintenance.

Endress+Hauser also offer support in the form of additional services, such as:

1. Calibration service on site or at the factory in an accredited laboratory.

2. Maintenance contracts for the installed instrumentation.

3. Training – customer-specific content and content on demand.
