Industrial wastewater is one of the key contamination sources in the pollution of water. With the rapid economic development, a huge amount of industrial wastewater has been discharged in to rivers, lakes and coastal areas during the last century and caused serious pollution and brought negative effects upon the eco-system and human life. This has resulted in many governments taking action to prevent, control and abate water pollution, thereby promoting the environmental monitoring industry to accelerate its transformation and upgrade. Compared to the accustomed method of examining wastewater discharge by manually sampling once every six months, there are more and more requirements for gathering real-time and long-term data so as to improve the effectiveness of monitoring.

In order to optimize manufacturing management, manufacturers need visibility to accurately control workflow information. As a result, there are more companies willing to implement Manufacturing Execution Systems (MES). According to the definition of Manufacturing Execution System Association (MESA), "MES delivers information that enables the optimization of production activities from order launch to finished goods." However, the lack of bottom layer information, which is responsible for the physical control of machinery and equipment, makes MES unable to maximize the effectiveness of factory automation. In addition, industrial grade devices to precisely acquire signals and immediately deliver data are also important for such automation applications due to the harsh environments in factories.
ABB is continuously seeking to further strengthen and expand its product portfolio. Across the world, the company’s research and development labs are hard at work creating the technologies, products and solutions that will further raise the productivity, efficiency and flexibility of its customers’ operations. The successes scored every year are numerous, and selecting the most notable of these is no easy task. The current selection is a cross section of recent highlights. Many of these, as well as other technological achievements, are discussed at greater length in this and forthcoming issues of ABB Review.
With a global increase in the demand for green energy solutions, the use of solar cells (aka solar panels) is quickly spreading to residential and commercial facilities, resulting in an increase demand in manufacturing and production equipment. The essential steps in the production process of a solar panel include: Pick-and-Place, high-speed movement, accurate positioning and fixed plug-in fitting. But it is the dislocation and false welding of components that are greater obstacles in the inspection procedure. Therefore, customers need to adopt high-speed multi-axis motion control with a machine vision system to improve their production efficiency
BenefitsIndia-based urea, ammonia and fertilizer manufacturer Krishak Bharati was revamping its ammonia extension plant in Hazira, Surat, to increase availabilty of the control system during production. The facility was challenged by very old technology that was holding back its performance. The plant was running a 25-year old Siemens system and decided a key step in the ammonia expansion project was to replace the old technology with new controllers and an advanced process knowledge solution.
