Japan has world-class water and sewage treatment facilities, and strives daily to maintain compatibility, to the extent possible, between human activities and a water environment. Many challenges must be overcome, however, and these facilities will have to be strengthened and improved in the future. Inheriting a legacy of water environmentrelated know-how and technology, Fuji Electric is supplying GENESEED products that aim to provide lifecycle support to the water environment infrastructure in the recycling-based society of the 21st century. This paper presents an overview, the basic concept, present status and future outlook for GENESEED.

As water and sewage treatment systems deteriorate and approach their replacement age, the reduction of long-term maintenance and operation expenses and the more effective utilization of resources have become important. Meanwhile, the lifecycle of electronic devices is steadily decreasing. This paper, introduces the GENESEED control and monitoring system, developed in response to the above circumstances, for the purpose of reducing lifecycle cost and for realizing sustained operation that is safer, more reliable, and more stable.

This paper presents example applications of the GENESEED system to newly constructed plants and to facilities that are transitioning from existing plants in the water supply and sewage treatment fields. These applications utilize GENESEED standard products and the latest system technology. The GENESEED system is scalable for large-size plants and realizes an easy-to-understand monitoring function capable of handling many types of data. At transition plants, the GENESEED system provides integrated operation and a smooth transition from existing types of data to new types of data. In addition, the GENESEED system strengthens data communication with control equipment near to the field level to configure a total system.

This paper introduces the types of display screens and automatic control standard software libraries used in a monitoring and control system for water treatment. In order to increase the quality and engineering efficiency of the GENESEED system, Fuji Electric has prepared many control standard software libraries for water treatment. These standard libraries were made to enhance the ease of operation and design, and were created based on a survey of previously delivered systems. As a result, improvements in the efficiency of both design and testing were realized.

This paper presents an overview of the functions and engineering of water treatment monitoring and control systems. Previously, the design of control programs for controlling equipment and the design of display screens for monitoring were implemented separately, but this GENESEED system uses the software parts of a library to implement integrated design. As a result, there is no need to engineer or test link definitions between the control program and monitoring/operation data as had been implemented in the past.

The application of the GENESEED system to water and sewage treatment plants has promoted improvements and enabled the guarantee of quality. This paper presents an overview of the GENESEED support tools for increasing engineering efficiency. The engineering database is a tool that was developed to increase the efficiency of design support and document creation. The plant simulation system was developed with the goal of realizing higher work efficiency, such as in the verification of plant compatibility, and higher quality of both design and testing.

A small and medium-scale monitoring and control system (EXIONSTAR) was developed for small and medium-scale water treatment plants. In contrast to the conventional and bulky DCS, EXIONSTAR inherits the crucial functions of environmental durability, reliability, long-term maintainability, and integrates the required functions and performance into small and medium-scale systems to realize higher cost-performance. Moreover, Fuji Electric provides a client/server configuration and a stand-alone configuration in a Windows environment in order to supply systems matched to customer needs.

The environment surrounding the water and sewage treatment business is changing dramatically, and more efficient business operation is being required. The types of communications available for use in a remote monitoring and control systems have increased, but in consideration of the usefulness of water and sewage facilities, i.e. operation that is safe, reliable and stable, the telemeter telecontroller, which has a high degree of reliability and a track record of success, is expected to play an important role in the future. This paper describes the functions of a remote monitoring and control system that uses the GENESEED system's telemeter telecontroller.

In recent years, as monitoring and control systems have become more automated and the number of full-time operators has been reduced, monitoring and control rooms have been transformed into working offices in order to boost work efficiency. GENESEED monitoring and control is based on the concept of non-directional space, and is used to create a flexible and expandable working space. Demand is increasing for monitoring and control desks that are versatile and can be used in both work and business meeting settings. The Vario, a new type of desk, was developed in response to this need, and is based on the concept of utility "from work to life (from a working space to a living space)."

The Ecological Switchgear and Control Gear is an environmentally- conscious product for use in water and sewerage systems, and conforms to the type II and type III environment levels prescribed by the ISO 14020 series. The Ecological Switchgear and Control Gear is a leading-edge product in this field, incorporating third-party certification of LCA (life cycle assessment) data and the "3R"s (reduce, reuse, recycle) that are promoted by the Japanese Ministry of Economy, Trade and Industry. This paper describes Fuji Electric's involvement with environmentally-conscious products and 3R compliance of the latest small high-voltage switchgears, compares LCA data for new and old types of low-voltage motor control centers, and discusses future development trends.

Euro terminals are used to achieve a high-density in miniaturized designs. The trend toward globalization of device procurement will compel the use of Euro terminals in the future. On the other hand, users have little information about Euro terminals and are concerned about their use. Thus, to evaluate Euro terminals, Fuji Electric has conducted evaluations and testing, in conformance with JIS, which investigate the Euro terminal structure and materials. The result showed that Euro terminals are mechanically equivalent to the current type of screw terminals and are additionally provided with structural measures to prevent looseness.

The source of drinking water in Japan is mainly rivers and streams. Because Japan is a small country, water from rivers and streams is often used repeatedly by circulating it from upstream to downstream regions and water quality management is important to secure safety and reliability of supplied water. Fuji Electric has developed and marketed water quality meters equipped with highly important functions for supporting the "stable supply of safe and reliable water" - from the water source to the water supply with water quality management at water treatment plants. This paper introduces the product line and uses of Fuji's new water quality safety monitors already on the market and the new trihalomethane monitor which will be brought to market shortly.

One challenge facing all types of solution systems that connect to monitoring functions is how to realize the required functionality regardless of the configuration of the monitoring and controlling system. GENESEED successfully accomplishes this task by configuring solution systems with a data connection function. This paper introduces the GENESEED connection platform that links data to the GENESEED system monitoring and controlling function, describes the capability of the GENESEED solution, and presents an overview of various solutions that run on the GENESEED connection.

Society's expectations for sewage treatment plants are increasing mainly in anticipation of advances in water processing and the more effective utilization of sludge resources. Fuji Electric is studying the integrated optimization of whole sewage treatment plants as a sewage solution. Fuji Electric has developed the "Sewage Treatment Plant Performance Evaluation System" (PES) and has systematized it as a menu of the GENESEED solution. PES technology is based on the sewage treatment plant performance table (PET) proposed by Professor Somiya of Ryukoku University (Professor Emeritus, Kyoto University). This paper discusses PES functions and a test of actual sewage plant data to verify applicability.

With the revision of Japan's energy savings law, Fuji Electric has developed an energy savings simulator for computing the optimal device configuration of the power receiving and distribution equipment at water purification plants and sewerage treatment plants. This simulator enables easy quantification of the effectiveness of such energy-saving measures as installing energy-saving devices and highly efficient devices, and enables more efficient operation through optimized control. Moreover, in an optimal control function comprised of several pumps and using a novel optimization method based on non-linear stability theory, pump startup, stopping and flow distribution can be computed automatically so as to minimize the power consumption of all pumps. As an example, the energy savings of a typical purification center was computed.
