Book Description
Aircraft washing operations generated large quantities of wastewater containing free and emulsified oils, and heavy metals in concentrations frequently exceeding local discharge limits. Oil/water separators have proven ineffective as a pretreatment method prior to discharging the wastewater into a sanitary sewer. The Naval Facilities Engineering Service Center developed and field tested a Closed Loop Aircraft Washrack Wastewater Recycle System (CLAWWRS) based on field-proven chemical treatment followed by pre-coat filtration technologies. The system was integrated with an existing washrack at Marine Corps Air Ground Combat Center, Twenty-nine Palms. Analytical results from field tests showed oil and grease removal to less than 15 pprn, and heavy metals consistently reduced under 0.1 ppm. Additionally, the chloride concentration in the recycle water was maintained well below the maximum allowable level of 400 ppm. Typical fresh water consumption of 100,000 gallons during combined armed exercises was reduced to 15,000 gallons. This User Data Package (UDP) provides information and guidance to activities requiring or using a CLAWWRS for their cleaning operations. This UDP addresses issues concerning economic feasibility, site selection and preparation, operator requirements and regulatory requirements. CLAWWRS operating instructions, system drawings, test data, site preparation requirements, economical analysis, and material safety data sheets can be found in the appendices.

Book Description
The past 30 years have seen the emergence of a growing desire worldwide that positive actions be taken to restore and protect the environment from the degrading effects of all forms of pollution – air, water, soil, and noise. Since pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be construed as an unreal- tic demand for zero waste. However, as long as waste continues to exist, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been identi?ed: (1) How serious is the pollution? (2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? This book is one of the volumes of the Handbook of Environmental Engineering series. The principal intention of this series is to help readers formulate answers to the last two questions above. The traditional approach of applying tried-and-true solutions to speci?c pollution p- blems has been a major contributing factor to the success of environmental engineering and has accounted in large measure for the establishment of a “methodology of pollution control. ” However, the realization of the ever-increasing complexity and interrelated nature of current environmental problems renders it imperative that intelligent planning of pollution abatement systems be undertaken.
