Chlorine Demand definition

Chlorine Demand means the difference between the amount of chlorine applied and the amount of free chlorine available at the end of the contact time, expressed in milligrams per liter.

Chlorine Demand means the difference between the amount of chlorine applied to a given water and the amount of total available chlorine remaining at the end of the contact period. All test conditions (contact time, pH and temperature) must be given, expressing the chlorine demand in a given water.

Chlorine Demand means the amount of chlorine required to produce a free chlorine residual of 0.1 mg/l after thirty (30) minutes contact time, expressed in milligrams per liter.

Examples of Chlorine Demand in a sentence

• Chlorine Demand - The result obtained when using an approved laboratory procedure to determine the difference between the amount of chlorine added to a sample and the amount of chlorine remaining in the sample at the end of a specified contact time at room temperature, expressed in milligrams per liter.

• Chlorine Demand: In systems that do not routinely chlorinate, this test reveals unusual demands on the oxidizing capability of the added chlorine, indicating the presence of a contaminant that warrants further investigation.

• Analyses by the CCUA showing not more than the following:• BOD - concentrations of 250 milligrams per liter (mg/l),• Chlorine Demand- concentrations of 15 mg/l,• Ph - not less than 6.0 nor more than 9.0• Suspended Solids - concentrations of 250 mg/l,• COD – concentration of 800 milligrams per liter (mg/l).

• For each sample a chromatogram of ultraviolet (UV) absorbance (absorbance units) against time (minutes) was produced.2.2.2 Chlorine Demand and Formation Potential Tests Chlorine demand was measured by determination of the chlorine residual after exposure to a range of chlorine doses.

• Chlorine Demand Free E-pure Chlorine demand free E-pure water was used to generate results for free and total chlorine calibration curves.

More Definitions of Chlorine Demand

Chlorine Demand means the difference between the amount of chlorine available at the end of the contact time, expressed in mg/l.

Chlorine Demand means the quantity of chlorine absorbed in water, wastewater or other liquids, allowing a residual of 0.1 parts per million (ppm) by weight after fifteen (15) minutes of contact. The standard laboratory procedure shall be as defined in the latest publication of 40 CFR Part 136 "Guidelines Establishing Test Procedures for the Analysis of Pollutants."

Chlorine Demand means the quantity of chlorine absorbed in water, sewage or other liquids, allowing a residual of 0.l ppm, after fifteen (15) minutes of contact.

Chlorine Demand means the difference between the amount of chlorine added to water, sewage, or industrial wastes" and the amount of residual chlorine remaining at the end of a twenty minute contact period at 68 degrees F. temperature;

Chlorine Demand means a measure of oxygen-consuming capacity of inorganic and organic matter present in water or wastewater. It is expressed as the amount of oxygen consumed from a chemical oxidant in a specified test. It does not differentiate between stable and unstable organic matter and thus does not necessarily correlate with biochemical oxygen demand. Also known as oxygen consumed (OCR) and dichromate oxygen consumed (DO), respectively.

Chlorine Demand means the difference between the amount of chlorine added to water or wastewater and the amount of residual chlorine remaining at the end of a specified contact period. The demand for any given water varies with the amount of chlorine applied, time of contact and temperature.

Chlorine Demand means the quantity of chlorine reduced or converted to inert or less active forms of chlorine by substances in the water, measured as the difference between the amount of chlorine applied and the amount of free chlorine available at the end of the contact time, and expressed in milligrams per liter.
