The SC25F is Yokogawa's first 12mm combination design digital SMARTpH sensor. It includes an integral temperature element and a Liquid earth electrode. This design provides a large electrolyte volume giving the sensor longer life than most comparable pH electrodes.
SPS24 PC Configuration and Calibration Software
The WU11 interconnection cable is specified for reliable transfer of digital signals between the SENCOM™ sensors and Yokogawa FLXA™ analyzer. It is espically designed to be installed in a heavy industrial environment. The cable is water proof, IP67, allowing it to be submerged as a whole. The cable has a wide temperature operation range which is sufficient for most of the applications. The materials used for the cable are flame retardant to resist the spread of fire.
Wet scrubbers are used in utilities, paper mills, and chemical plants to remove sulfur dioxide (SO2) and other pollutants from gas streams. Undesirable pollutants are removed by contacting the gases with an aqueous solution or slurry containing a sorbent. The most common sorbents are lime, Ca(OH)2, and limestone, CaCO3.
For control of batch neutralization, a pH measurement coupled with a timer-controlled chemical feed scheme provides very satisfactory results.
This system can be adapted for either acid waste or alkaline waste neutralization.
In flue gas desulfurization systems that use magnesium hydroxide (Mg(OH)2) slurry, the consumption of the desulfurization agent (Mg(OH)2) is controlled by using online pH analyzers. A great concern in the pH measurement is heavy staining of the pH electrodes by the Mg(OH)2 slurry. To ensure accurate measurement, frequent cleaning of the electrodes with an acid is required, adding to both maintenance workload and cost.
The lifetime of a pH sensor has a significant impact on the overall annual costs of a pH measuring loop. Optimizing four key factors will decrease these costs and optimize process control and overall plant efficiency.
Are Pure water, Ultrapure water, UPW, or Water for Injection (WFI) important in your process? Would a better understanding of current water treatment equipment technology be useful? Would learning to better identify sources for potential process problem be helpful?
Pure water, Ultrapure water, UPW, Water for Injection (WFI), high-purity water and deionized (DI) are all terms describing basically the same property. They refer to water which has been purified to the highest standards by removing all contaminants such as, organic and inorganic compounds; dissolved and particulate matter; volatile and non-volatile, reactive and inert; hydrophilic and hydrophobic; and dissolved gases. Pure water or conditioned water is used in a variety of processes across various industries; Power Generation, Pharma/Biotech, Semiconductor, and Drinking water are just a few examples.

How to choose the right reference and measuring electrode for your application, which includes:
Each of the previous webinars covered the basics and the monitoring requirements for a high purity water treatment system that included a Reverse Osmosis (RO) treatment step. In this final webinar, we cover the problems that poor RO unit performance can produce in downstream process steps and in the end use water. The webinar series started with topics concerning raw water contaminants and will end with following contaminants through the RO membrane and into downstream treatment steps including Electrodeionization (EDI), mixed-bed ion exchange, 185 nm and 254 nm UV, ozone and more. Join us and learn:
A common use for RO is for purifying water, removing salts and other impurities to improve the color, taste and other properties. It is regularly used for commercial and residential water filtration and is also one of the methods used for desalinization of seawater. RO systems are capable of rejecting bacteria, salts, sugars, proteins, particles, dyes, and other constituents which have a molecular weight of greater than 150-250 Daltons. RO systems are designed for automatic operation and require routine preventative and corrective maintenance. Common problems include membrane fouling and the use of improper flow rates. The result is reduced throughput capacity and shortened runs. What you will learn:
