The Carmeuse Lime & Stone glossary of terms is a great resource for our customers and visitors. Here you can find definitions for many industry terms and acronyms regarding the multiple uses of lime. You'll find this section to be a useful supplement to the research papers and case studies available through our website. Locate a definition in the immediate display of general terms or choose an industry from the list to find terms specific to their application.

The quantitative capacity of aqueous media to react with hydroxyl ions.
The capacity of water to neutralize acids, a property imparted by the water's content of carbonates, bicarbonates, hydroxides and occasionally borates, silicates and phosphates. It is expressed in milligrams per liter of equivalent calcium carbonate.
Water that contains dissolved matter at an approximate concentration range from 1000 to 30,000 mg/L.
Water that contains dissolved matter at an approximate concentration of more than 30,000 mg/L.
The amount of chlorine required to achieve, under specified conditions, the objectives of chlorination.
The reciprocal of the resistance in ohms measured between opposite faces of a centimetre cube of an aqueous solution at a specified temperature.
That part of the subsurface water that is in the saturated zone; water directly below the earth's surface that is in the saturation zone.
The polyvalent-cation concentration of water (generally calcium and magnesium).
A reversible process by which ions are interchanged between an insoluble material and a liquid with no substantial structural changes of the material.
The number of milliequivalents of exchangeable ions per millilitre of backwashed and settled bed of ion-exchange material in its standard form.
The electromotive force developed by a noble metal electrode immersed in the water, referred to the standard hydrogen electrode.
The amount of oxygen required, under the specified test conditions for the oxidation of waterborne organic and inorganic matter.
The logarithm of the reciprocal of the hydrogen ion activity in aqueous solutions. A measure of the strength or intensity of a water's acidity or alkalinity. Water with a pH of 7.0 is neutral. A pH less than 7.0 indicates an acidic water, while a pH greater than 7.0 indicates an alkaline water.
The concentration of dissolved matter found in water after bromide and iodide have been replaced by an equivalent quantity of chloride, all carbonate converted to oxide, and all organic matter destroyed.
Any solid or semisolid or liquid waste generated from a municipal, commercial, or industrial wastewater treatment plant water supply treatment plant or air pollution control facility (wet scrubbers) or any other such waste having similar characteristics and effect.
A mixture of water and any finely divided insoluble material (fly ash, slaked lime, etc.) in suspension.
Reduction of transparency of a sample due to the presence of particulate matter.
A process employing semipermeable membrane under a hydraulic pressure gradient for the separation of components in a solution. The pores of the membrane are of a size which allow passage of the solvent(s) but will retain non-ionic solutes based primarily on physical size, not chemical potential.
That matter that is changed under conditions of the test to the gaseous state.
Water discharged from a process as a result of its formation or use in that process.
Any accumulation of insoluble material derived from water or formed by the reaction of water upon the surfaces in contact with the water.
