A report on the increasing usage of chemicals in water treatment, particularly the use of coagulants and flocculants. (BB)

A special report on the state of the water pollution control industry reveals that due to forthcoming federal requirements, sales and the backlogs should increase; problems may ensue because of shortages of materials and inflation. Included are reports from various individual companies. (MLB)

Regional and supraregional treatment centers have been developed in Switzerland to cope with the problem of systematic toxic waste disposal. The process employed at the Fairtec Turgi plant is described beginning with delivery and storage and proceeding through treatment, reprecipitation, decontaminating cyanide, filtering sludge and ion-exchanger…

Discusses the roles of leading firms, consulting engineers and equipment manufacturers in the growing field of water pollution control. Reviews of individual companies are given. (BL)

Examples of user experiences of the Enviro Monitor are cited together with advantages for its use. This is an all-weather instrument capable of making a continuous record of pollutants and controlling unattended operations at remote locations under adverse weather conditions. (BL)

Most waste treatment techniques conceived to meet the 1977 standards can be separated into three distinct phases: primary, secondary and tertiary treatment. An examination of the four heaviest industrial water users, pulp and paper, steel, plating, and food processing, demonstrates these treatments use proven technology to meet specific…

Industry is faced with handling, disposing and recovering vast amounts of waste, much of it as a result of present pollution control technology. Industry has found the technology available, expensive and, without regulation, easy to ignore. Many industries are therefore improperly managing their wastes. (BT)

Describes technologies used to conserve energy by using process wastes in the following situations: (1) incineration at a photographic company, (2) wet oxidation at a paper mill, and (3) sewage skimmings fuel at a municipal waste water plant. (MA)

The pulp and paper industry are being forced by economic considerations and air pollution regulations to consider alternatives to the use of sulfur systems, be they kraft, acid or neutral sulfite. To meet environmental requirements and combat erosion of profits, modernized non-sulfur pulping methods will increasingly appear on the scene. (BT)

The problems that are encountered when cooperation breaks down between the industrial source operator and the pollution control equipment vendor are examined. The focal point of this examination is the study of defenses available to the equipment vendor when industrial source operators refuse to cooperate. (Author/BT)

Through capsule reports, seminars, and design manuals, Environmental Protection Agency has activated its industrial technology transfer program for marketing the products of federal research, development, and demonstration activities. Its purpose is to disseminate information to industry on available technology for control and treatment of air,…
