Chlorine definition

Chlorine means dry chlorine.
Chlorine means total residual chlorine.
Chlorine means an element that at room temperature and pressure is a heavy greenish yellow gas with a characteristic penetrating and irritating smell; it is extremely toxic. It can be compressed in liquid form and stored in heavy steel tanks. When mixed with water, chlorine gas forms hypochlorous acid (HOCl), the primary chlorine-based disinfecting agent, hypochlorite ion, and hydrochloric acid. HOCl dissociation to hypochlorite ion is highly pH dependent. Chlorine is a general term used in the MAHC which refers to HOCl and hypochlorite ion in aqueous solution derived from chlorine gas or a variety of chlorine- based disinfecting agents.

  • The following table of quantification levels will be used to determine compliance with NPDES permit limits: Parameter PQL ML Chlorine, Total Residual 0.050 mg/l -- This permit may be modified, or, alternatively, revoked and reissued, to include more stringent effluent limits or conditions if information generated as a result of the conditions of this permit indicate the presence of these pollutants in the discharge at levels above the water quality based effluent limit (WQBEL).


More Definitions of Chlorine

Chlorine means a chemical agent that exists as a gas in its elemental form or as a part of a chemical compound which is an oxidant. It is a bacteriological agent used to disinfect the water in public swimming pools.
Chlorine means an element that at room temperature and pressure is a heavy greenish yellow gas with a characteristic penetrating and irritating smell; it is extremely toxic. It can be compressed in liquid form and stored in heavy steel tanks. When mixed with water, chlorine gas forms hypochlorous acid (HOCl), the primarychlorine-based disinfecting agent, hypochlorite ion, and hydrochloric acid. HOCl dissociation to hypochlorite ion is highly pH dependent. Chlorine is a general term used in the MAHC which refers to HOCl and hypochlorite ion in aqueous solution derived from chlorine gas or a variety of chlorine-based disinfecting agents.• “Available Chlorine” means the amount of chlorine in the +1 oxidation state, which is the reactive, oxidized form. In contrast, chloride ion (Cl–) is in the -1 oxidation state, which is the inert, reduced state.Available Chlorine is subdivided into Free Available Chlorine and Combined Available Chlorine. Pool chemicals containing Available Chlorine are both oxidizers and disinfectants. Elemental chlorine (Cl2) is defined as containing 100% available chlorine. The concentration of Available Chlorine in water is normally reported as ppm (mg/L) “as Cl2”, that is, the concentration is measured on a Cl2 basis, regardless of the source of the Available Chlorine.• “Combined Available Chlorine” or “Combined Chlorine” or “CAC” or “CC” means the concentration of available chlorine present in the form of inorganic or organic chloramines. Combined available chlorine is less reactive than free available chlorine and organic chloramines are generally less reactive oxidizers than the inorganic chloramines. Combined chlorine is determined by taking the difference between the Total Chlorine (TC) and DPD-FC concentrations. CC = TC – DPD-FC.• “Cyanurate-bound available chlorine” or “CBC” means the concentration of available chlorine that is bound to cyanurate.• “DPD Free Chlorine” or “DPD-FC” means the FC (“free chlorine”) concentration from DPD-based test methods. The DPD-based test result for FC includes cyanurate-bound available chlorine as well as HOCl and OCl-, that is, DPD-FC = FAC CBC. The terms DPD-FC and FAC would be interchangeable only in the absence of cyanuric acid.• “Free Available Chlorine” or “FAC” or “Free Chlorine Residual” means the portion of the total available chlorine that is not “combined chlorine” or “cyanurate-bound available chlorine” and is primarily present as hypochlorous acid (HOCl) or hypochlorite ion (OCl-). Molecular ...
Chlorine means the chemical element “Cl” that exists as a gas in its elemental form and which is an oxidant and biocidal agent, used in swimming pool disinfection. Chlorine may be derived from chlorine gas, calcium hypochlorite, sodium hypochlorite, trichloro-s- triazinetrione or lithium hypochlorite. Sodium dichloro-s-triazinetrione (dichlor shock) is excluded from this definition.
Chlorine means a chemical agent that exists as a gas in its elemental form or as a part of a chemical compound which is an oxidant. It is a bacteriological agent used to disinfect the water in pools, spas, or other water features.

It can be compressed in liquid form and stored in heavy steel tanks. When mixed with water, chlorine gas forms hypochlorous acid, the primary chlorine-based disinfecting agent, hypochlorite ion, and hydrochloric acid. Hypochlorous acid dissociation to hypochlorite ion is highly pH dependent. Chlorine is a general term used in these regulations which refers to hypochlorous acid and hypochlorite ion in aqueous solution derived from chlorine gas or a variety of chlorine- based disinfecting agents.• “Available Chlorine” means the amount of chlorine in the +1 oxidation state, which is the reactive, oxidized form. In contrast, chloride ion (Cl–) is in the -1 oxidation state, which is the inert, reduced state. Available Chlorine is subdivided into Free Available Chlorine and Combined Available Chlorine. Pool chemicals containing Available Chlorine are both oxidizers and disinfectants. Elemental chlorine (Cl2) is defined as containing 100% available chlorine. The concentration of Available Chlorine in water is normally reported as mg/L (PPM) “as Cl2”, that is, the concentration is measured on a Cl2 basis, regardless of the source of the Available Chlorine.• “Free Chlorine Residual” OR “Free Available Chlorine” means the portion of the total available chlorine that is not “combined chlorine” and is present as hypochlorous acid (HOCl) or hypochlorite ion (OCl-).The pH of the water determines the relative amounts of hypochlorous acid and hypochlorite ion. HOCl is a very effective bactericide and is the active bactericide in pool water. OCl- is also a bactericide, but acts more slowly than HOCl. Thus, chlorine is a more effective bactericide at low pH than at high pH. A free chlorine residual must be maintained for adequate disinfection.
