Ozone Disinfection: Case Study: Newport News Uses Emerson Ozone Instrumentation For Safe, Effective Disinfection
Maintaining the quality of the water supply is the top priority for municipal drinking water treatment plants across the country. Water plants use several treatment processes to ensure water quality and safety, and these treatment steps include disinfection. Traditionally, chlorine is used in both primary and secondary disinfection treatments and has been used since 1908. Some water plants are moving to ozone for primary disinfection. One water utility that is taking this direction is Newport News Waterworks. Newport News Waterworks constructed a pilot plant that uses ozone in the primary disinfection process

What Is pH, And How Is It Measured? pH is defined as the negative logarithm of the hydrogen ion concentration. This definition of pH was introduced in 1909 by the Danish biochemist, Soren Peter Lauritz Sorensen. By Frederick J. Kohlmann
ORP Based Measurement Of Oxidizing Disinfectants In Aqueous Solutions
Oxidizing antimicrobials, such as chlorine, are common disinfectants used to treat water. Test strips, DPD kits, and colorimeters are currently the most popular methods for determining the relative disinfecting power of oxidizing antimicrobial agents in these applications. By Myron L Company
Isolation Seals Protect Transmitters When Measuring Difficult Fluids
Isolation seals protect transmitters while faithfully conveying pressure signals. They enhance the measurement of not only pressure and vacuum, but also of derived variables, including flowrate, level, and density. Because of their measurement flexibility, electronic differential pressure (DP) transmitters are widespread throughout industrial and municipal processes.
Case Study: Italian Waste Water Plant Turns To Endress + Hauser For Control System Automation The urban and industrial sewage treatment plant, in the Liguria region, is based on the biological action of active sludges in two distinct treatment lines: one for treating the sewage, the other for treating the sludge itself. The control system has been based on a completely open architecture based on the ControlCare Field Controller (FC) by Endress+Hauser. The system may be expanded in future whenever necessary without decreasing performance, while maintaining the same prerequisites for functional simplicity. Thanks to the use of standard Foundation Fieldbus function block technology, the FCs form a single distributed control architecture based on an HSE (High Speed Ethernet) network. The function blocks are interconnected via links constituting the central nervous system for control. Each FC deploys a Profibus DP local digital network (integrated Master PFB DP) and manages the discrete utility signals on local I/O boards
White Paper: What Is pH, And How Is It Measured? Almost all processes containing water have a need for pH measurement. The pH of wastewater leaving manufacturing plants and wastewater purification plants, as well as potable water from municipal drinking water plants, must be within a specific pH "window" as set forth by local, state, or federal regulatory agencies. By Frederick J. Kohlmann

The Commission owns and operates a 10 mgd slow sand filtration plant in Oregon City, OR that treats Clackamas River water.
Case Study: TOC Online Measurement In Wastewater From Paper Factory Depending on the type of wood being used, the wastewater may also be subject to widely fluctuating pH values. Moreover, elevated temperatures (30 - 35 °C) are typical, and so cooling is necessary prior to discharge into the sewage treatment plant. By Endress + Hauser, Inc.

Wastewater Instrumentation

Process instruments are used widely in water and wastewater treatment plants to monitor the effluent quality. However, their applications are not limited to monitoring effluent quality. These water and wastewater quality monitoring devices can be applied throughout the network of collection, treatment, and disposal

Instrumentation can give guarantee of proficient treatment processes of water quality parameters such as turbidity, pH, ORP, conductivity and dissolved oxygen. Instrumentation is done in the following aspects.

Flow measurement
Stage /Level measurement
Physical and chemical water quality measurement
Biological water quality measurement
Water sediment and biota samplers
Data storage and management

Measurement Techniques include, Gravimetric analysis or, simply, weighing, Colorimetry or spectrophotometry, Titration, and Mass Spectrometry:

Platforms on which instrumentation can be carried out include

Stationary vertical profilers – Used for in situ sampling.
Flow-through systems -Most research ships have built-in flow-through systems that constantly circulate water collected a few meters from the surface.
Towed vehicles- towed vehicle such a system is able to provide a continuous series of data points for remote sensing applications where transect lines can follow the flight paths of a remote sensor.
Moored platforms - These stationary, or Eulerian, platforms offer data streams synoptically that match with satellite-based imagers.
Automated underwater vehicles - Autonomous Underwater Vehicles (AUVs) afford their own propulsion there by allowing high-resolution sampling of the ocean’s interior in multiple directions.

Some of the instruments used in water management are:

Pressure Transmitters
General Service Gauges
Pressure Regulators
Digital Panel Meters
Process Calibrators
Thermometers
Differential Pressure Gauge and Switches
Multi-Point Thermocouple Displays
HART Calibrator/Communicator
