Agua y agua residual

The Metropolitan Cebu Water District (MCWD) needed to improve its water supply system to keep up with the growing demand.
Yokogawa installed field instruments at a total of 143 locations in MCWD’s water distribution network and a SCADA system with water leakage management software at the main office to reduce non-revenue water and improve stability of water supply.

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.

- DDMO for the optimization of the air-blowing rate of the aeration tanks
- Interlink between DCS and DDMO to maximize the energy saving effect

RDR operates total 67km long race and supplies irrigation water to vast agricultural land in NZ's South Island.

FAST/TOOLS and STARDOM RTU were selected for management of the race and hydropower systems.

• Más de 1,000 equipos de campo diseñados para las especificaciones de PROFIBUS fueron instalados en la planta de regeneración de agua state-of-art.
• La alta confiabilidad y precisión de nuestros dispositivos de campo contribuye a la minimización de los costos de mantenimiento durante todo el ciclo de vida de la planta

• Innovative GEOLIDE waste water treatment complex in Marseille uses CENTUM and Exaquantum. 
• The visualization of all data on items such as motor and pump operating time and chemical consumption amount allows operators to optimize key operation items.

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.

As water and wastewater systems expand, scalable centralized monitoring enables efficient management of distributed assets and meets evolving user demands.

Yokogawa DPharp EJA/EJX Pressure transmitters do not need frequent re-zeroing due to superior long term stability, it contributes to reduce maintenance time.

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. 

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.

La configuración del transmisor de nivel puede tomar mucho tiempo. Los transmisores DPharp tiene la función de un software avanzado eliminando esta tarea que toma tiempo. Con talleres de mantenimiento cada vez más pequeños, la búsqueda de equipos que nos permiten hacer más con menos se convierte en una prioridad.

Durante casi 100 años, el ozono se ha utilizado en todo el mundo para la sanitación del agua. Es oxidante más fuerte de la naturaleza y tiene un subproducto de oxígeno puro. El cloro, por otra parte, es un producto químico muy efectivo, comprobado químicamente, pero es ineficaz contra los microorganismos difíciles de matar tales como cryptosporidium; también tiene algunos subproductos desagradables. El Ozono es reconocido entre los más rápidos, desinfectantes y oxidantes fuertes disponibles en el mercado para el tratamiento del agua, el Ozono se utiliza tanto en la desinfección del agua potable y el asesino bacteriano en el tratamiento de aguas residuales. El Ozono se utiliza en un gran porcentaje de las instalaciones de tratamiento de aguas municipales, así como en las compañías farmacéuticas en dónde es esencial el agua pura.

A Basic Guide to Accurate & Reliable Flow Measurement.

Optimizing four key factors will decrease pH sensor costs and optimize process control and overall plant efficiency.

In this Yokogawa RAP Best Practices eBook, you’ll discover how our wealth of knowledge about Integrated Safe Systems and Control of Work is available to help you and your teams design and implement a system that best suits your needs.

When selecting a Level Measurement device, what to consider in order to be accurate and repeatable?

Industrial process automation has evolved significantly over the years, playing a pivotal role in improving operational efficiency, safety, cost reductions, and ensuring product quality. Traditional automation systems, however, often relied on proprietary, closed architectures, leading to vendor lock-in, interoperability challenges, and limited adaptability to changing business needs often required for enterprises to expand or progress. Industrial process automation has evolved significantly over the years, playing a pivotal role in improving operational efficiency, safety, cost reductions, and ensuring product quality.

In this Whitepaper by Mark Hammer you will learn about:

• The movement away from proprietary, closed architectures
• How OPA avoids vendor lock-in and interoperability challenges
• Changing business needs requiring flexible systems to progress

By understanding what causes the difficulties in pH measurements and having the proper equipment, stable and accurate pure water pH measurement can be accomplished.

Asset health monitoring has long been in existence to protect expensive equipment and/or operations from costly, critical, or catastrophic failures, with numerous examples in nuclear, aeronautical, petrochemical, industries and beyond. The costs associated to install the sensors and asset health system way overcome the consequences of not implementing. However, this is not the case in all industries, with all equipment and/or all operations. In many cases equipment is run until failure and then repaired or replaced.

Yokogawa Electric Corporation, one of the leading manufacturers of industrial recorders, put the DAQSTATION DX series stations on the market in 1999, which added information processing and transmission functions to conventional recorders.

In recent years, more field wireless devices have been used in hazardous areas. Meanwhile, in plants that are usually recognized as hazardous areas, there are numerous metallic tanks and pipes that easily shield or reflect radio waves, as discussed later, thus resulting in a poor environment for wireless communication.

For large scale geographically dispersed projects, there may be a hierarchy of individual Process Automation systems, which in turn are each responsible for a specific region, and are managed by a higher level system. Engineering of systems on this scale is a huge challenge, because each individual system has its own database and its own configuration.

As compared to Distributed Control Systems (DCS) such as CENTUM VP that monitors the operations of the overall plant, PRM is a type of Plant Asset Management (PAM) software package that primarily focuses on the maintenance of devices and instruments.

In plant sites, there are various places such as those affording an unobstructed view like tank yards, and others surrounded by metal pipes and equipment obstructing the view (hereafter referred to "pipe jungles"), often seen in oil refinery and chemical on-site plants. The frequency band of radio waves used for field wireless communication is 2.4 GHz, which has high straightness and its ability to go around things can hardly be expected.

In recent years, expectations for control systems using wireless communications have been increasing in the process control market. This is because these systems do not require power and communication wiring for field instruments, enabling reduced initial and maintenance costs, and easy installation.

The introduction of wireless into industrial monitoring and control not only reduces wiring and maintenance costs but also expands its applications to include those which are impossible with wired systems, such as monitoring points which have to be given up due to the difficulty of the construction, and monitoring of points on rotating or frequently moved objects.
