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 ...

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.

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.

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.

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.

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

Types and Significance of Chlorine Residuals

Journal AWWA, 1959
When the presence of residual chlorine in water can be demonstrated, the effectiveness of chlorination is definitely insured, and continues as long as the residual is present. Soon after the practice of water chlorination was started about 50 years ago, it was discovered that a control was necessary to insure disinfection. The method of control devised

Determination of Residual Chlorine Compounds

Journal AWWA, 1951
emphasize the importance of accurate methods of determining concentrations of the various kinds of residual chlorine present. In two recent reviews Palin (1, 2) discusses the various methods which have been proposed and describes a new titration method.

AUTOMATED CHLORINE RESIDUAL CONTROL

Journal AWWA, 1969
Automated chlorination can be accomplished by a variety of control systems, each of which leaves some margin for error and unbalance. A new system refines accuracy and stability by employing techniques that lead to system performance characteristic of the linear control loop.
