November 2002Analytical Instrumentation & Environmental Monitoring
The first fully enclosed, totally automated water treatment plant in Africa has been completed and is now being operated successfully in Windhoek, Namibia. Selected by project managers DB Thermal of Johannesburg to supply an extensive range of process measurement equipment for the extension of the Goreangab wastewater treatment plant, Endress+Hauser contributed equipment worth more than R800 000 to the unique facility.
The plant makes use of a Profibus bus system for communication between PLCs, remote stations and field instruments. This allows for more than just process variables to be communicated - field instruments can also report any specific problems that might cause instrument malfunction at any given moment in time. In addition, overall plant control is now more reliable, since all control valves are linked via Profibus.
As direct sunlight and certain weather conditions can impact on the efficiency of certain filtering processes, the plant was fully enclosed. This will also prolong equipment life. Able to supply the full basket of Profibus instrumentation, Endress+Hauser delivered level, pressure, flow and analytical sensors, as well as samplers. Various applications ranging from inlet works flow monitoring to final drinking water quality assessment were involved. This underlines the convenience of being able to source all instrumentation components from a single supplier, especially since the thermal dispersion flow meters - for measuring ozone flow - were specified by the client, following its successful application in a similar environment in Switzerland.
In line with Endress+Hauser's total solutions approach, whereby the company partners with other suppliers and rely on dedicated industry specialists to ensure that clients receive a complete solution instead of just products and components, it supplied support in the initial engineering phase of the project, provided an on-site technician for the duration of commissioning and is also looking to agree on a maintenance plan that will see the continued success of yet another step towards alleviating Africa's potable water supply dilemma.
