Active conservation treatment processes

The discharge from both domestic and industrial wastewater treatment plants (for example, from activated sludge processes) has been a low-cost source of makeup for cooling systems for many years. Efforts to reuse water continue to gain momentum for environmental conservancy and economic reasons, but the fact that secondary use waters are, by definition, of a lower grade than other supply sources inevitably means an increased risk of deposition or fouling problems in the cooling system. 

Waste Minimization Waste minimization is any effort to reduce or recycle the quantity of waste generated, and when feasible, to reduce or eliminate toxicity. It includes any source reduction or recycling activity undertaken to reduce the total volume or quantity of hazardous waste and/or the toxicity of hazardous waste, with the goal of minimizing threats to human health and the environment. Waste minimization focuses exclusively on solid wastes regulated under the Resource Conservation and Recovery Act (RCRA), and does not include treatment, unless the treatment is part of the recycling process. However, it is broader in scope than P2 to also include recycling and other means to reduce the amount of waste that must be treated or disposed of off- or onsite. 

The treatment is usually conservative in nature with avoidance of excessive activity that will create the symptoms. An explanation of the condition assists the child and the parents in understanding the cause of the pain and the necessity of resting the knee during the healing process. Occasionally, the tubercle may be pinned to the tibia to create early fusion. 

The major industrial water use and handling activities (i.e., cooling, process operations, water treatment, and steam production) should be viewed individually for opportunities to improve pollution control performance and reduce pollutants, as well as in an integrated fashion to conserve energy and avoid duplication in treatment. For example, in process operations improved housekeeping,...
