multi-input analyzer, water quality, instrumentation, water, waste water, process industry, efficiencies, digital controllers
Today`s process world is a challenging one. Plant managers, metrology labs, and maintenance workers are constantly asked to improve their process efficiencies and output while at the same time seeing their budgets, manpower, and workforce reduced.
Fortunately, companies that serve the process industry have used these impo
Ordinarily pH measurements are made in water with 1,000 to 10,000 µS/cm conductivity. The conductivity comes from dissolved solids which are typically salts but also acid or base. These dissolved substances are in the solution in ion form which makes such solutions conducting. With conductivities of 1,000 µS/ cm or more, an ample supply of mobile ions provides pH electrodes with a good electrical circuit to yield fast, accurate pH readings. In pure water with low conductivity, sta
Importance of pH Measurement
Hydrometallurgical concentrating and refining applications require pH/ORP sensors to withstand aggressive environments while maintaining accurate measurement. Processes such as cyanide leaching (e.g gold) and solvent extraction (e.g. copper, nickel, zinc) require pH and ORP to be at very specific values to yield the desired chemical species. pH may need to be controlled as precisely as ±0.05 for some processes. Even where this
DISSOLVED OXYGEN CHEMISTRY
Dissolved Oxygen (DO) is a measure of the amount of oxygen, usually thought of as a gas, that is dissolved in a liquid such as water. Oxygen is essential to life and is also the most common element found taking part in corrosion reactions. DO can be thought of as the fuel needed for the corrosion process to proceed. It is the corrosion reactions that necessitate trace (boiler) DO analyzers; such as IC Controls 865-25 or 869-22 portable that are
Abstract
In 1967, the steel industry realized bottom blowing process after the shrouded injector had been invented by Canadian Guy Savard and Robert G.H.Lee. While in the nonferrous metallurgical industry, top blowing] process was industrial applied in Australia in 1987. And side blowing Noranda process went into industrial production in Canada in 1973. Then in 1991 the pilot test of bottom blowing copper smelting process was done by using the lances like structure of th

Abstract
Losses of metal are often traced to incorrect pH/ORP signals in floatation, leaching, extraction, electrolysis, and precipitation processes, aggravated by pressure changes. IC Controls a Canadian mining sensor manufacturer developed a new superior pH/ORP sensor that stops metal losses, reduces environmental footprint and contributes to sustainability. The cause of incorrect pH/ORP signal is rooted in the reference junction. Reference Junctions are designed to al

Definition
Total Dissolved Solids (TDS) is a measure of the sum of all inorganic and organic substances in a liquid in molecular, ionized or micro-granular colloidal suspended form. The solids must be small enough to survive filtration through a sieve the size of two micrometer. TDS solids are normally found in all freshwater systems. Major applications of TDS are: at low levels the study of water quality for streams, rivers, lakes, potable water taste, and at h
Industrial Process Description
Cyanide-containing waste is produced in various industries such as mining and electroplating. Processes such as stripping, cleaning, and plating generate wastes that can include metal cyanide complexes with alkaline iron, nickel, zinc, cadmium, copper, silver, and gold. Wastes containing cyanide are required by both US EPA law 40 CFR pan 413 & 433." and Ontario. Canada. 560/94 to be discharged below 1 ppm monthly. These levels may be de
High Purity Water Resistivity/ Conductivity Measurement
Ultra-Pure Water without any chemical impurities will still have a conductivity because of the presence of H* and OH" ions due to the self-ionization of water. Ultra-pure water has a conductivity of 0.055 HSiemens`cm or a resistivity of 18.18 mQ-cm at 25 °C. In order to know the conductivity or resistivity of ultra-pure water it is required to do accurate temperature compensation at very low conductivities, e.g.
pH measurement in the petrochemical industry is frequently extremely difficult. Operating in high temperatures with highly reactive contaminants traditional pH reference electrodes can, in some applications, last only days.
IC Controls 613 sensors reference is designed for difficult applications particularly where fouling or poisoning conditions exist. The reference uses a highly stable non-porous polymetric interface in place of the traditional porous liquid junction used by all c
