摘要:

The problem of haloforms in drinking water treatment has made necessary to investigate new treatment methods capable of reducing the amount of halo-compounds formed when chlorination must be maitained in particular for disinfection, in the network. In laboratory test, as well as in pilot and industrial studies, different treatment lines have been tested. The measurement of precursorsand humic acids, and the use of chlorine as a decomplexing agent for humic matter give the possibility to determine the kinetic conditions for haloforms appearance during potable water treatment and to define a treatment line avoiding halogenous compound formation.

摘要:

A new antibiofouling ozone system with an intermittent injection of high-concentration ozone has been developed. The system was demonstrated to be effective for preventing biofouling on surfaces in fresh water stream. The application of the system reduces remarkably both the capital and the running costs compared to adopting conventional ozonation method.

摘要:

The authors review mass transfer of ozone to water with or without chemical reaction. In order to calculate the dimensions of an ozone-water contactor, it is necessary to know its characteristics without chemical reaction (KL) and with chemical reaction.

摘要:

In water treatment plants equipped with large–scale ozonation facilities, specific safety measures must be constantly reviewed and tested. Safety of employees : in high concentrations, ozone becomes a poisonous gas. This requires adequate means for detection of ozone in traces in the ambient air. ventilation and destruction. individual protection Safety of plant and equipment : ozonation has become an essential phase in the treatment process and ozonators must be fitted with safety devices for the detection and rapid control of hazardous conditions.

摘要:

In the operation ofozone treatment plants, one will have to deal with ozone inthe off–gas exhaust air. In higher concentrations in the exhuast air, ozone has the unpleasant property of being detrimental to plant, animal and man.

摘要:

ABSTRACT: Center, type and underline Abstract heading, capitalizing the first letter. A double-space should separate the heading from the abstract text. Indent approximately 1/2 inch (13 mm) from both left and right margins for typing the abstract. The abstract should be approximately 50 to 70 words in length. It should be factual and contain the main results and conclusions of the paper. It should be intelligible to the reader without reference to the body of the paper and be suitable for reproduction by abstracting services. Introduction to the text (without a heading) should begin two spaces below the abstract using full margins.
