Controlling Parameters in Water Analysis
Pure Water and Highly Purified Water
Pure water and highly purified water are crucial factors to production in numerous processes and industries and can be used as a raw material, auxiliary and/or for process operation. It is very important to pay particular attention to the quality of the water used as it is crucial to product quality and the safe operation of the production facilities. Therefore, continuous monitoring is essential - from an ecological as well as an economic point of view.
Process water is one of the most challenging for analysis instrumentation. Mostly this water is characterized by a certain purity, fluctuating loads, as well as very high salt concentrations. Since any disturbance in water-circuits can lead to an entire plant shutdown, resulting in huge costs, reliable and fast online water analyzers are an essential. Due to the diverse demands of various measurement challenges, application-specific analyzers provide huge advantages against standard analyzers that are used for...
Waste water, especially industrial waste water, is the most challenging water for instrumentation. Mostly, this water is characterized by highly fluctuating loads, very high salt concentrations as well as a high particle density. Hence, the accurancy and speed of measurements depends on the measurement system itself and the oxidation technique used. Obviously, application-specific analyzers provide huge advantages against standard analyzers that are used for all applications.

PeCOD® Analyzer oxygen demand analysis for source & treated drinking waters
MANTECH’s chemical oxygen demand (COD) analyzer is breaking new ground in the science of monitoring source and treated drinking water. In addition to providing 15-minute COD results and biochemical oxygen demand (BOD) estimates, MANTECH’s PeCOD® Analyzer measures natural organic matter (NOM) in raw and treated drinking water. The NOM Analyzer™ — which is the drinking-water application of MANTECH’s novel PeCOD® COD-testing system — does what no other technology has...
Online Chemical Oxygen Demand for Treatment Optimization - Case Study
A wide variety of products are made in the chemical and pharmaceutical manufacturing industries, that require large volumes of chemicals, materials, and substances that are used throughout process operations. Waste water from these facilities typically include contaminants, toxins, nutrients, and organic content that presents challenges with regards to treatment. A major UK based chemical manufacturing facility had lost a large amount of product to the waste stream, and as a result, incurred charges from the...
What is Chemical Oxygen Demand (COD)?
Chemical Oxygen Demand (COD) analysis is a measurement of the oxygen-depletion capacity of a water sample contaminated with organic waste matter. Specifically, it measures the equivalent amount of oxygen required to chemically oxidize organic compounds in water. Why Measure COD? COD is used as a general indicator of water quality and is an integral part of all water quality management programs. Additionally, COD is often used to estimate BOD (Biochemical Oxygen Demand) as a strong correlation exists between COD...
Nitrogen Demand Increases for Semiconductor: How Safe Are You?
As users demand ever-smaller smartphones and better televisions, semiconductor manufacturing plants are tasked with developing new products faster and using new materials. Key to the continued success of the semiconductor industry are inert gases, which include nitrogen and argon. When used safely, both nitrogen and argon play a number of important roles within the semiconductor plant. Yet, these gases poses a health hazard for employees if a leak occurs. How and Why Nitrogen is used in Semiconductor Manufacturin...
