Wastewater Treatment

• More than 1,000 field devices designed to the PROFIBUS specifications installed in the state-of-the-art water reclamation plant.
• The high reliability and accuracy of our field devices contributes to the minimization of maintenance costs over the entire plant lifecycle.

STARDOM field control node (FCN) autonomous controllers allow both Modbus master and slave functions to run simultaneously.

Yokogawa's Optical Dissolved Oxygen Sensors offer reduced maintenance time and longer maintenance cycles for efficient process optimization.

Fish are totally dependent upon water to breathe, feed, grow, maintain a salt balance, and reproduce. Water quality determines the success or failure of an aquaculture operation.

What is screen differential control? This is a control application commonly found at utility plants located on rivers, lakes and other large bodies of water and at industrial facilities where a large amount of cooling water is used.

Dairy wastewater is a mixture of organic compounds, suspended solids, fats, and bacteria that can produce a film or coating on equipment in the process. 

The ADMAG AXR employs the patented “Dual Frequency Excitation Method.” This unique technology combines the best properties of low-frequency excitation to enable a stable measurement and high-frequency excitation to deliver excellent noise immunity. As a result, the AXR can suppress process-generated noise to secure zero stability without sacrificing fast response time. In addition, the AXR achieves the same level of noise immunity as a 4-wire circuit under varying fluid conditions and delivers the performance necessary to meet the requirements for control loop applications.

Wastewater from electroplating facilities and certain types of chemical plants contains toxic forms of hexavalent chromium such as chromate and dichromate. The hexavalent chromium in this wastewater must be reduced before the water can be discharged. This requires a two-step process: hexavalent chromium (CR₆) is reduced to trivalent chromium (CR₃); and CR₃ is precipitated as chromium hydroxide.

Cyanide-bearing wastewater from mining and electroplating facilities and certain types of chemical plants is toxic and must be treated by oxidation with chlorine or chloride to bring the cyanide concentration within regulatory limits.

Data acquired on the SMARTDAC+ GM can be easily monitored through the company network, even from remote locations.

Manage dissolved oxygen levels in the wastewater treatment system reliably with Yokogawa’s Dissolved Oxygen Converter System.

The detectors used to perform dissolved oxygen (DO) measurement in oxidation ditch type sewage treatment plants tend to become dirty quickly and require frequent cleaning.

Taking advantage of sensors already available in your system, you can simply add VJ series signal conditioners or the UM33A Digital Indicator with Alarms to easily build a monitoring system on a PC.

Ozone is recognized among the strongest, fastest, commercially available disinfectants and oxidants for water treatment, ozone is used in both the disinfection of drinking water and bacterial killer in wastewater treatment.

The worlds of process automation and production management have been converging for some time. What once used to be islands of automation and production management functionality connected through highly proprietary integration schemes that were costly to maintain have developed into integrated platforms that provide seamless data exchange between the world of automation and the plant floor, the functions of production and operations management, and integration with business level systems.

From engineering to installation, commissioning, operations, and maintenance, FOUNDATION fieldbus offer significant cost reductions of 30 percent or more versus conventional analog systems. Many of these cost reductions come from the advanced functions that fieldbus offers versus analog technology.

The automation suppliers that will be successful in the long term will be those that effectively address application or industry specific problems for end users with a value proposition that cannot be ignored. These problems exist throughout the process industries today, and they won't be solved by simply offering a product, but through a combination of hardware, software, services, application expertise, and knowledge.

In ARC's view, customers need a compelling business value proposition to justify investment in any kind of automation. Vigilance and VigilantPlant were created with this in mind. Yokogawa's vision with VigilantPlant is to create an environment where plant personnel and operators are well informed, alert, and ready to take action.
