The SSP manual is targeted at a variety of users at different levels including; health authorities and regulators, local authorities, wastewater utility managers, sanitation enterprises and farmers, community based organizations, farmers associations and NGOs. SSP brings together actors from different sectors to identify health risks in the sanitation system and agree on improvements and regular monitoring and underscores the leadership role of the health sector."--Publisher's description.
Download or read book Water Reuse at Highway Rest Areas written by Clinton E. Parker and published by . This book was released on 1977 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The limited availability of water and stringent wastewater effluent standards at rest areas led to the development of a water recycle-reuse system to treat flush water from water closets. Flush fluid for rest area water closets accounts for 95% to 97% of the rest area water requirements. For a flush fluid to be acceptable it must have no objectionable odors, no objectional color, no substantial foaming, and no apparent suspended solids, and it must be low in bacterial count and chemically and biologically stable. Prior research with a bench-scale system confirmed the application of extended aeration biological treatment followed by granular media filtration as a water recycle-reuse concept. This prior work led to the installation of a full-scale field system at a rest area to develop data for implementation of the recycle concept. The treatment system at an existing rest area was modified to provide a closed loop return of water to and from the water closets. A water balance was achieved by wasting an amount of recycle water equal to the water input from sewered potable water. Data from the field recycle-reuse system were obtained during its operation from November 15, 1976, to August 31, 1977. During this time start-up was evaluated and equilibrium was achieved and evaluated at 95% recycle. The biological system and filtration system provided flush water of a quality that met standards set for flush water and was accepted by the users. Operation of the closed loop extended aeration and granular filter system for flush water recycle and reuse was similar to the conventional operation of these processes. The influence of nitrogen accounted for the most significant operating difference. Ammonia nitrogen transformation to nitrite and nitrate nitrogen resulted in an operating pH of 5.5 to 6.0 and, as a result, incomplete nitrification occurred. Nitrogen buildup in the form of ammonia, nitrite, and nitrate was experienced but the concentrations did not cause a reduction in the organic biological oxidation efficiency. The biological system functioned under conditions suitable for the utilization of organics by fungi. The biological solids were threadlike; however, they readily separated through gravity settling. The quality of the water in the recycle-reuse system varied between winter and summer operation, but it remained acceptable as a flush fluid. The variability in quality can be attributed mainly to nitrogen. Nitrogen in the recycled water greatly influences biochemical oxygen demand results and renders this test useless as a measure of organic stability. Storage requirements for recycle flush water are dictated by the resident time of the users in the building that houses the water closets, the resident time of users in the parking facility, and the physical layout of the water closet facility. Average daily and maximum daily water use based on resident times and gallons (litres) per user establishes storage, biological treatment, and filter requirements. Instantaneous peak flow establishes pipe sizes and integration of system requirements for storage and use sets pump requirements.

Download or read book Evaluation of Two Washrack Recycle Treatment Systems written by Gary L. Gerdes and published by . This book was released on 1999 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated two commercial off-the-shelf washrack wastewater recycle treatment systems (a Landa and an RGF) to determine their applicability at Army facilities. The evaluation assessed the resource requirements for installation, operation, maintenance and repair, and also assessed the effectiveness of the treatment. The two systems were found to use somewhat similar treatment processes. After a 3-month evaluation for each system, the results of the evaluations were also similar. Both systems required significant resources for in-house labor and for service. Neither system could be operated continually in an automated closed loop mode. Removal of organics was inadequate, and slugs of organics (e.g., glycol and diesel fuel) passed through the systems. These systems would not be recommended for use at Army installations unless: (1) the cost to connect the washrack to sanitary sewer was exceptionally high, or sanitary sewer was not available, or (2) the washrack was in a water short area where recycle was required.

Available in PDF, EPUB and Kindle. Book excerpt: In communities all around the world, water supplies are coming under increasing pressure as population growth, climate change, pollution, and changes in land use affect water quantity and quality. To address existing and anticipated water shortages, many communities are working to increase water conservation and are seeking alternative sources of water. Water reuse- the sue of treated wastewater, or "reclaimed" water, for beneficial purposes such as drinking, irrigation, or industrial uses- is one option that has helped some communities significantly expand their water supplies. Understanding Water Reuse summarizes the main findings of the National Research Council report Water Reuse: Expanding the Nation's Water Supply Through Reuse of Municipal Wastewater. The report provides an overview of the options and outlook for water reuse in the United States, discusses water treatment technologies and potential uses of reclaimed water, and presents a new analysis that compares the risks of drinking reclaimed water to those of drinking water from traditional sources.

Available in PDF, EPUB and Kindle. Book excerpt: Expanding water reuse-the use of treated wastewater for beneficial purposes including irrigation, industrial uses, and drinking water augmentation-could significantly increase the nation's total available water resources. Water Reuse presents a portfolio of treatment options available to mitigate water quality issues in reclaimed water along with new analysis suggesting that the risk of exposure to certain microbial and chemical contaminants from drinking reclaimed water does not appear to be any higher than the risk experienced in at least some current drinking water treatment systems, and may be orders of magnitude lower. This report recommends adjustments to the federal regulatory framework that could enhance public health protection for both planned and unplanned (or de facto) reuse and increase public confidence in water reuse.
