Drinking Water Treatment

Yokogawa in the Water Industry

What is Drinking Water Treatment?

It is the process of removing contaminants, such as microorganisms, chemicals, and other impurities, from raw water to make it safe for human consumption. This involves several stages including coagulation, sedimentation, filtration, disinfection, and sometimes additional steps such as fluoridation or pH adjustment. The goal is to produce clean, safe, and potable water that meets regulatory standards and is suitable for drinking and other domestic uses.

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:
  • The aging DCS system was replaced with an integrated control system for all processes at the Siheung water treatment plant.
  • Powerful Modbus communication function of STARDOM enables integration with the existing HMI via the OPC gateway.
Overview:
  • To bring the customer a real-time monitoring and management capability, Yokogawa installed STARDOM (FCJ), flow meters, and transmitters at key points throughout the distribution network.
  • The STARDOM FCJ controllers achieved an accurate water loss management system while keeping the running costs to a minimum.
Overview:

The City of Eugene contracted Yokogawa for the challenging solution to enhance their control system with a secure wireless network to operate a wastewater treatment facility with a peak capacity of 277 million gallons daily using five processes.

Water Supply Treatment
FAST/TOOLS, STARDOM, Flowmeters, Liquid Analyzers

  • Bali's water treatment plant decided to employ the latest reliable control system in order to increase availability and quality of operation.
  • Centralized control system using FAST/TOOLS provides the sophisticated and flexible operation.
Overview:

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

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.

Overview:

Yokogawa’s Sushi temperature sensor is a cost-effective, reliable, long-range wireless communication for monitoring and recording to boost reliability, and also able to configure the network with redundant gateways for chemical manufacturers.

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:

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:

Japan's Potable Water Quality Standard was fully revised in 2004, increasing the number of water quality standard items for which tests are required has increased to 50. As items necessary for water quality management, the authority has specified an additional 27 complementary parameters to set the targets for water quality management.

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.

Industry:Electrical and Electronics

Overview:

Weir-type flow volume calculation using the M series Free Programmable MXS (or VJXS) Computing Units

Overview:

Environmental data (water quality, amount of flow) is measured on-site and monitored from an office.

Overview:

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

Overview:

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

Overview:

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.

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. 

Overview:

Yokogawa has come a long way in making its message clear to the world of process automation. Last year, the company embarked on a full-scale global marketing campaign to make customers aware of the company's focus on system reliability, security, dependability, and robustness. Dubbed "Vigilance", the campaign created a unified message for the company and greatly helped expand awareness of the Yokogawa brand and corporate philosophy.

Overview:

Process automation end users are under more pressure than ever to do more with less. The current economic climate means that many automation capital projects are on hold. With capital budgets tighter than ever, users instead focus on operational budgets (where cost cutting is also a key concern), or on automation investments with a very rapid return on investment.

Overview:

In today's dynamic industrial marketplace, the only constant is change. Raw material costs, energy costs, market demands, environmental and safety regulations, technology, and even the nature of the labor force itself are constantly changing, and not always in predictable directions.
