Greywater recycling: Treatment options and applications

Wastewater is an immense resource that could find significant applications in regions of water scarcity. Greywater has particular advantages in that it is a large source with a low organic content. Through critical analysis of data from existing greywater recycling applications, this paper presents a review of existing technologies and applications by collating a disparate information base and comparing/contrasting the strengths and weaknesses of different approaches. Simple technologies and sand filters have been shown to have a limited effect on greywater; membranes are reported to provide good solids removal but cannot efficiently tackle the organic fraction. Alternatively, biological and extensive schemes achieve a good general treatment of greywater with particularly effective removal of organics. The best overall performances were observed within schemes that combine different types of methods to ensure effective treatment of all the fractions

Code of good practice on dump closing or conversion to sanitary landfill at federal establishments

This Code provides recommended practices for personnel who are engaged in the management of solid wastes at Federal establishments. In keeping with the Federal Government Cabinet Decision of June 8, 1972, entitled "Control and Abatement of Pollution from Federal Activities - Cleanup and Prevention-, the Government wishes to provide a consistent and exemplary environmental pollution control program by reviewing, and where necessary, upgrading the design, operation, and maintenance of Federal installations, thus offering leadership in the nation-wide effort to protect and enhance the quality of our environment. Use of this Code is intended to promote a consistent approach towards the cleanup and prevention of water, air and land pollution and ensure that the best practicable control technology is used. Its purpose is to assist Federal agencies in developing waste management programs, and plans and specifications for the construction and operation of Federal facilities. In addition to this Code, the following guidelines and codes of good practice have been prepared to cover other associated areas of environmental concern: 1. Code of Good Practice for Management of Hazardous and Toxic Wastes at Federal Establishments, 2. Guidelines for Effluent Quality and Wastewater Treatment at Federal Establishments, 3. Code of Good Practice for Handling Solid Wastes at Federal Establishments, 4. Guidelines Applicable to Incinerators at Federal Establishments, 5. Interim Guidelines Applicable to Boilers at Federal Establishments
