Wastewater Treatment

Yokogawa in the Water Industry

What is Wastewater Treatment?

It is the process of removing contaminants and pollutants from used water, often referred to as wastewater, before it is discharged back into the environment or reused. This process involves several stages such as primary treatment, where large solids are removed, secondary treatment to break down organic matter using biological processes, and tertiary treatment to further remove remaining contaminants and pathogens. The goal is to produce treated water that meets environmental regulations and can be safely released into bodies of water or reused for purposes like irrigation or industrial processes.

Resources

Overview:
  • 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.
Overview:

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

Overview:

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

Application Note
Overview:

One of the most common applications for differential pressure transmitters is flow measurement. DPharp differential pressure transmitters have some unique signal conditioning features to eliminate instability at low flow rates.

Application Note
Overview:

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.

Overview:

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. Screen differential control and monitoring is needed to prevent damage to rotating screens caused by excessive pressure being applied by debris collecting on the screens.

Overview:

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. 

Overview:

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.

Overview:

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.

Industry:Electrical and Electronics

Overview:

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.

Overview:

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.

Overview:

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.

Overview:

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.

Overview:

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.

Overview:

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.
