Monitoring Chlorine Residuals

Journal AWWA, 1984
In this letter, White comments that the conclusions reported by Ram and Malley in “Chlorine Residual Monitoring in the Presence of Norganic Compounds” (Journal AWWA, September 1984) may be misleading to operators at wastewater or reclaimed water plants.

Reduction of chlorinated hydrocarbon residues in swine

Bulletin of Environmental Contamination and Toxicology, 1971
The occurrence of residues of chlorinated hydrocarbon insecticides in animal tissue has been well established in the literature. Thomas et al (I); Fahey and Brindley, (2); Entomology Research Division (3) are three authors who reported the contamination of beef tissues resulting from the feeding of treated forage or permitting livestock to forage on ...

Process for Disposal of Chlorinated Organic Residues

Journal of the Air Pollution Control Association, 1965
A continuous process for the disposal of halogen-containing organic residues has been developed. This process is based on the decomposition of wastes into gaseous byproducts by high temperature reactions with air and steam. The exit gases, which are essentially carbon dioxide, nitrogen, and hydrogen halides, can be scrubbed with water, thereby ...

Chlorinated hydrocarbon residues in the fish of lake Tanganyika

Bulletin of Environmental Contamination and Toxicology, 1976
The use of chlorinated hydrocarbon pesticides for the control of tropical diseases and the treatment of agricultural crops in Central Africa has [ncreased tremendously since it was started in 1954 (LAMBRECHT, 1954; BRION, 1962). Even though the levels of residues from such pesticides have been studied extensively in many parts of the world, there are ...

QUALITY VS. RESIDUAL CHLORINE

Journal AWWA, 1971
Chlorine residual, an indication of adequate chlorination of a water supply, has a definite relationship with the bacteriological quality of the supply. This paper discusses how much, what kind of, and the proper surveillance of, chlorine residual.

Chlorine Residual and Bacteriological Quality

Journal AWWA, 1942
problem of the relation of chlorine residual to bacteriological quality of drinking waters resolves itself, in a sense, into whether a stipulated residual may be employed as an index of safety in respect to bacterial quality and hazard of transmission of disease.

Chlorinated Hydrocarbon Residues in Airborne Fallout

Nature, 1972
IN an analysis of the input and output of chlorinated hydrocarbon residues in a freshwater ecosystem in south Sweden, the amount entering the study area by means of precipitation and by airborne particles was estimated.

Evaluation of Residual Chlorine

Journal AWWA, 1935
Ortho-tolidine has been used almost exclusively for the estimation of residual chlorine in water since its standardization in 1913 by Ellms and Houser (1), and its development by Wolman and Enslow in 1918 (2). Prior to that time the then less delicate starch iodine method had been used.

Advances in Chlorine‐Residual Analysis

Journal AWWA, 1975
Chlorine has historically been chosen for the disinfection of water supplies. Its germicidal efficiency and the long‐lasting effectiveness of chloramine residuals in the distribution system are responsible for its continued popularity. Unfortunately, techniques for continuous process analysis capable of differentiating between chlorine‐residual species
