Process Water

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 every application.

Cooling Water

Cooling water key facts

Cooling water is used in almost any industry. It serves as heat transfer medium for the heat dissipation of buildings and processes. Generally, all cooling systems have one thing in common: The cooling medium is water.

There are several methods of cooling on the market that differ significantly with regards to their design and the composition of the cooling medium used. The most common methods in power plants and in the energy supply industry, minding that mixed and special forms are also used, are once-through cooling, recirculative cooling, open-circuit cooling and closed-circuit cooling.

Often cooling water is obtained by using surface water. Depending on the application, the water must then be treated before usage. However, cooling water becomes waste water when it is pre-treated by use of chemicals or changed in its composition by product spills or thickening. Therefore the cooling water systems' effluent should be continuously monitored. To prevent contaminated influents, a continuous monitoring of TOC at the influent is advisable.

Important parameters for the assessment of cooling water are the TOC and toxicity. With its Quick-series LAR provides an appropriate analyzer for each cooling water challenge. Furthermore, the ToxAlarm is optimally suited for the monitoring of toxicity of effluents.

Process Water

Process water key facts

Usually, process water is characterized by having suspended and dissolved pollutants as well as a complex water composition. It may involve toxic chemicals, high salt concentrations, or in case of an accident, organics as oils, fats or other substances. Hence, the reliance on reliable measurements is enormous. Whether adhesive properties, high and fluctuating loads or a wide variety of water compositions, tailor-made online water analyzers are specialized to specific process water to perform an optimally measurement process.

Accuracy in the online analysis of process water allows conclusions about the functionality and effectiveness of a production facility to be drawn. The right measurement technique enables the fast detection of product spills and provides the opportunity to take countermeasures.

For the toughest applications, LAR Process Analysers AG presents its Ultra-series. The analyzers QuickTOCultra, QuickCODultra or QuickTONultra provide reliable measurements of TOC, COD and TNb. Combinations of these parameters are possible.
