Mr. Moreland is available to discuss Air Force projects and issues concerning storm water and wastewater pollution prevention. A primary focus of the manual will be the discouragement of O/WS use in favor of implementing pollution prevention initiatives to eliminate the generation of oily wastewater discharges. The pump moves the oily water to the adjacent oil/water separator (D). Also included within the manual will be several flow diagrams that help guide readers through decision processes. Floor drains in maintenance bays may not be necessary in all cases, particularly if a "dry" process can replace a "wet" process and eliminate a wastewater stream.

Operations and Maintenance: ZEKS OSB™ Oil/Water Separators are effective for reducing the hazardous waste content in compressed air condensate. MIL-HDBK-1138, Wastewater Treatment System Operations and Maintenance Augmenting Handbook, 31 October 1997. In an effort to update and maintain environmental technology user requirements, the U.S. Army Environmental Requirements and Technology Assessments (AERTA) WWW site has been developed and is hosted on DENIX at http://www.denix.osd.mil/denix/DOD/Policy/Army/Aerta/default.html. It is important for each installation to contact their state and local regulatory agencies for information on regulations and standards applicable to oil/water separators. water into the floor drains. As the water cools, the grease and oil separate and float to the top of the grease trap. Develop and implement a plan for each base to assess the need for, and effectiveness of, existing oil/water separators with the goal of consolidation or elimination of ineffective units. Therefore, it is important to prohibit the discharge of certain types of potential contaminants into an O/WS, and to regularly analyze sludge samples to determine toxicity prior to disposal. Occasionally, simple gravity type O/WSs do not remove enough oil for the resulting wastewater to meet regulatory discharge requirements. It also discusses the fact that, in recent years, many of the oil/water separators installed by the military are not performing adequately due to problems with the design, selection, introduction of the wrong types of wastes, and lack of proper maintenance. 2701, et seq. These regulations are codified at Title 40 CFR Parts 110, 112, 116, and 117. If O/WSs are improperly used, their sludges and oils can become contaminated with a variety of hazardous substances. 13101, et seq. COVID-19 Corona Virus South African Resource Portal. Section 311 (Oil and Hazardous Substance Liability) of the CWA establishes requirements for preventing discharges of oil and other hazardous substances, and requires certain action for spills. Install a double liner with leak detection system for new separators including associated oil recovery tanks. MIL-HDBK-1005/16, Wastewater Treatment System Design Augmenting Handbook, 31 October 1997. Eliminate unpermitted pollutants and prohibit discharge of wastewater from industrial operations containing hazardous wastes and heavy metals. However, oil/water separators work best when they receive only oils and water. Nominal capacity of the separator. MIL-HDBK-1138, Wastewater Treatment System Operations and Maintenance Augmenting Handbook, 31 October 1997. All shops with floor drains shall be operated according to Oil/Water Separation Technology User's Reference and Application Matrix. Collect, treat, and dispose of industrial waste separately. MIL-HDBK-1138, Wastewater Treatment System Operations and Maintenance Augmenting Handbook, 31 October 1997. Eliminate unpermitted pollutants and prohibit discharge of wastewater from industrial operations containing hazardous wastes and heavy metals. After passing through a floor drain, contaminated water must run through a grease trap in commercial kitchens and an oil separator at fuel stations and car washes before flowing into sewer systems. (NOTE: Title 40 CFR Part 63, Subpart VV, National Emission Standards for Oil-Water Separators and Organic-Water Separators, regulations do not apply to O/WSs at Air Force installations. U.S. Army Environmental Requirements and Technology Assessments (AERTA) WWW site, http://www.denix.osd.mil/denix/DOD/Policy/Army/Aerta/default.html. It may be appropriate to connect the drain directly to a properly designed, installed, and maintained oil/water separator; or to an intermediary sump or holding pond/basin. If it cannot be prevented, it should be recycled. An O/WS has upper limits to the amounts of oil and sludge that can effectively accumulate while it is in operation. . In addition, cold climates may pose a problem if the unit is exposed to the elements. Excessive use of detergents can render an O/WS inefficient by completely emulsifying oils into the wastewater stream and allowing it to pass through the system. However, O/WSs require pumping of the wastewater from the area of the floor drain, possibly causing increased turbulence and less efficient separation. ), and administrative rules promulgated thereunder. Federal Facility Compliance Act (42 U.S.C. Oil/Water Separation Technology User's Reference and Application Matrix, http://aec-www.apgea.army.mil:8080/prod/usaec/et/ows/titlepage.htm. Air Force Policy/Guidance There are a number of excellent reference documents that can assist installations with the design, installation, and maintenance of O/WSs. Perform a comprehensive inventory of all existing oil/water separators (including on-line oil and grease/fuel traps, and small oil/water separators outside of hangars, corrosion control facilities, fuels transfer/storage operations, Aerospace Ground Equipment (AGE) maintenance shops, wash racks, etc.). More information concerning RCRA-regulation of O/WS tanks is presented in a 1989 letter to Hunt & Hunt Engineering from the United States Environmental Protection Agency (EPA), copies of which are available from PRO-ACT. Air Force Instruction (AFI) 32-7041, Water Quality Compliance, 13 May 1994. . It also discusses the fact that, in recent years, many of the oil/water separators installed by the military are not performing adequately due to problems with the design, selection, introduction of the wrong types of wastes, and lack of proper maintenance. Locate the oil/water separator on the base utility as-built drawings and update the information as changes occur. Reference Documents DRAFT AFI 32-7080, Compliance Assurance and Pollution Prevention (will revise existing AFI 32-7080, Pollution Prevention Program, 12 May 1994).

Reference Documents Dispose of sludge as a hazardous waste and retest wastewater from oil/water separator to assure compliance. Where motor vehicles are serviced and stored, an oil separator shall be installed with a static water capacity of 1 cubic foot for every 100 square feet of area to be drained. With properly placed floor drains, less water will be required to drain away liquids. Here's my test. Emulsifying Agents Inlet Sumps / Sand Traps. Docurment References Optimizing DoD Investments in Oil/Water Separators and Closed-Loop Recycle Treatment Systems, U.S. Army Environmental Center (USAEC), 1997. http://aec-www.apgea.army.mil:8080/prod/usaec/et/ows/titlepage.htm, http://www.denix.osd.mil/denix/DOD/Policy/Army/Aerta/default.html, http://www.denix.osd.mil/denix/DOD/Policy/Army/Aerta/Need_assessment/A22e/a22e_a.html, http://www.afcesa.af.mil/Directorate/CES/Civil/WasteWtr/Wastewtr.htm. Excessive use of detergents can render an O/WS inefficient by completely emulsifying oils into the wastewater stream and allowing it to pass through the system. For More Information . Often times people use “water as a broom” to wash away spills and debris. If too much oil accumulates in the receiving and middle chambers, it may flow into the wastewater outlet chamber and end up being discharged to the environment. ), and administrative rules promulgated thereunder. The series has been adopted for use by the military and addresses most topics pertinent to wastewater treatment O&M. The grease is actually trapped by baffles, which cover the inlet and outlet of the tank, preventing grease from flowing out of the trap. It includes typical wastewater characteristics and specific guidance on selecting, procuring, and implementing treatment and recycling systems, including oil/water separators. Separating compressor oil from the condensed water allows for safe and cost-effective condensate disposal in accordance with local regulations.

If the sludge is hazardous, take immediate actions to identify and eliminate sources of hazardous pollutants. In addition, paragraph 3.5.2 states that efforts to achieve wastewater compliance will be focused on many factors, including the elimination/minimization of point sources such as O/WSs. If too much oil accumulates in the receiving and middle chambers, it may flow into the wastewater outlet chamber and end up being discharged to the environment. O/WSs should be given the same close attention given to any other important piece of equipment. Also included within the manual will be several flow diagrams that help guide readers through decision processes. Reduce oil concentrations well below five parts per million. A listing of the REOs and the geographical areas they cover can be obtained from the AFCEE World Wide Web site at http://www.afcee.brooks.af.mil. store oil recovered by the separation process and all other equipment or containers at a regulated facility that do not qualify for the wastewater treatment exemption are required to meet the applicable SPCC requirements (67 FR 47069, July 17, 2002). Waste stream discharges by installations to their own federally operated treatment works (FOTWs) historically have not been subject to federal pretreatment regulations. Visit this WWW site at http://aec-www.apgea.army.mil:8080/prod/usaec/et/ows/titlepage.htm. Floor drains can mix many sources of waste, including wash water, used oil, chemicals, and sediments into a single difficult-to-manage semi-liquid stream. A (2.2.e), Improve Oil and Grease Removal/Treatment Technologies for Contaminated Wastewaters and Sludges/Soils, contains links to many useful equipment vendor sites (skimmers, centrifuges, filters, coalescing units, etc.) Identify monitoring and discharge limits. As always, PRO-ACT is available to respond to questions from our eligible customers concerning oil/water separators. Pollution Prevention Act (PPA) (42 U.S.C. Perform a comprehensive inventory of all existing oil/water separators (including on-line oil and grease/fuel traps, and small oil/water separators outside of hangars, corrosion control facilities, fuels transfer/storage operations, Aerospace Ground Equipment (AGE) maintenance shops, wash racks, etc.). However, O/WSs require pumping of the wastewater from the area of the floor drain, possibly causing increased turbulence and less efficient separation. The Oil-absorbing Oil/Water Separator utilizes 2-stage absorption bags to attract and hold oil like a magnet. Mr. Shah is available to discuss Air Force policy issues concerning O/WS including funding, installation, replacement, and removal. Also provided are recommendations for implementing the concepts presented in the report, including installing recycling units, removing O/WSs, installing pre-treatment systems, plugging drains, and preventing discharges. Rather than having a floor drain that runs into an independent sediment separator unit, the SD series is designed to be an all-in-one unit. The series has been adopted for use by the military and addresses most topics pertinent to wastewater treatment O&M. In addition, it separates and retains greasy and oily wastes, preventing their evacuation into the drainage lines where they cause blocking and stoppages. Mercer supplies a line of cylindrical below-ground, high-performance, oil/water separators from 50-5,000 gpm (10-1,000 m3/h). This field is for validation purposes and should be left unchanged.
