Frequently Asked Questions About Oil Water Separators and Sewer Discharge Systems

1. Why should I buy a RGF Oil Water Separator or Sewer Discharge System when I do not have any EPA discharge problems? You are in violation of EPA regulations if you do not have a discharge permit and are discharging vehicle wash water to the ground, septic tank or storm sewer. Eventually the EPA will notice you, or someone will report you to them in order to collect the reward money that they offer in their "Whistle Blower" program, and they you will have ten problems.
  1. You must stop cleaning your equipment.
  2. You may have to pay a fine up to $25,000 per day for minor violations.
  3. You are listed as a violator on the EPA computer, which is monitored by Environmental Activist Groups.
  4. Your company looks bad in the eyes of your employees and the community.
  5. From then on, your company will be closely inspected by the EPA, which could result in an expensive mandatory clean-up.
  6. Your company could be the subject of adverse media attention.
  7. You could be contaminating your property, which could negatively affect value or future sale.
  8. Your company could face a civil suit filed by citizens or activists.
  9. 1990 legislation has changed criminal violations from misdemeanors to felonies.
  10. Like the saying goes, "pay me know or pay me later."
2. Why will the run-off from a simple truck or heavy vehicle cleaning operation pollute my property and ground water?
Oil, grease, fuels, and paint contain hazardous materials such as benzene, lead, chromium, arsenic, pesticides, herbicides, nitrates, etc.   Over months of cleaning these hazardous materials build up to a dangerous and illegal volume.  In addition, it is illegal to discharge oils, detergents, degreasers, pesticides, etc. to the ground.  Eventually these contaminants permeate through this soil and pollute our ground and drinking waters.
3. How does the customer determine what his individual waste treatment needs are?
Since RGF specializes  in wastewater management, we are experienced in making the process fast and simple for the customer.  We maintain a fully equipped testing laboratory to determine what contaminants are present in the customer's water.  These tests are provided free of charge.  Once the pollutants and a few other key facts have been identified.  RGF can help the customer choose the proper system for his needs.  RGF will also work with the customer after the unit has been installed in order to handle any changes in his waste treatment needs. We pride ourselves on gaining and maintaining the satisfaction and respect of our customers. RGF has been awarded the INC. Magazine Customer Service Award.  RGF also offers free analysis of your water for as long as you own our systems to ensure treatment and safety is as effective as possible.
4. How does RGF assure all the contaminants are removed from the waste stream?
We utilize only technologies rated by the EPA as Best Available Technology or (BAT).  Then we borrowed a philosophy from the Aerospace and Nuclear Industries redundant systems, each system has a backup. Then we did them one better.  We have a minimum of triple redundancy.  For each contaminant, we use at least three BAT's to remove it!  For example: if the waste stream contains benzene, we would use aeration, ozone, hydrocarbon absorption foam, catalytic oxidation, carbon, and activated carbon, as many as five redundant technologies.
5. Who has RGF sold Oil Water Separators and Sewer Discharge Systems to, and how many are currently in service?
RGF has sold over 12,000 systems all over the world.  Our clients include numerous fortune 500 companies, major trucking firms, national waste haulers, heavy equipment companies, oil companies, state and local government utilities, U.S. Navy, U.S. Army, U.S. Air Force, Nuclear Plants, and NASA to mention only a few.  Many of these companies have conducted lab and field tests, in some cases using and independent agency to evaluate the system. We are proud to say we have never failed an evaluation.
6. Why not collect and store the wastewater for shipment to a water treatment plant? There are five reasons why this is a poor choice:
  1. Construction of a tank large enough to contain your run-off and the required secondary containment is expensive; a 10,000 gallon tank will cost approximately $10,000.
  2. Such a system would probably require you to obtain permits, which can be a difficult process.
  3. Regular inspection of the tank and monitoring wells will be necessary. In addition, the tank will have to be a double containment vessel.
  4. It is becoming increasingly difficult to find waste treatment plants that will accept water contaminated with oil and grease.
  5. There will be a continual shipping expense of as much as $2 per gallon and rapidly rising.
7. Can The RGF System be modified to handle other contamination problems?
Yes. We can add a flocculation unit with coagulation/flocculation chemicals to remove heavy metals by sedimentation. We can also add a pH control system to adjust water pH for contaminant removal (acid cracking) or to meet pH discharge requirements. There is also a "RGF Aeration Tower" Unit for separation of volatile solvents.
8. How does a sewer treatment plant know what I discharge and why do they care?
Sewer treatment plants, in most cases, are designed to treat human waste. Petroleum, hydrocarbons, heavy metals and other hazardous materials destroy the natural balance of the plant. Therefore, the government has developed their own "point source" program, which requires each business to clean-up there own waste steam to meet EPA or local discharge requirements. Recently, EPA has required 1,500 publicly owned treatment plants to perform a yearly inspection of all industrial discharge to assure compliance. Also, many treatment plants have remote monitoring programs, which can isolate problem industries. The federal EPA monitors the sewer treatment plant discharges.
9. I am on municipal sewer and I've been told all I need is an oil/water separator and I can discharge - isn't that true?
Oil water separators can separate free oils from water.  They do not work on soluble petroleum, hydrocarbons, emulsified oils, heavy metals, or most other hazardous materials.  Therefore, discharge of soapy wash water through an oil water separator will do little, if anything.  We have developed our SD (sewer discharge) unit to help with this problem.  It has the ability to filter solids, remove heavy metal, and many other hazardous materials. The SD System has 12 proven technologies to treat your waste stream.  In addition, oil water separators are typically in the ground and therefore subject to underground tank rules.  The SD System offers molded color impregnated UV protected polyethylene tanks and are installed above ground.
10. What if I am currently under a "stop work" order, will RGF work with me and the EPA to get me in operation again? Yes, RGF's staff of environmental experts are available to assist you in solving your wastewater problems. Our experts are active in many professional societies. We have been published in many technical journals and environmental engineering textbooks, and speak at over 12 conventions or seminars per year. You could say we wrote the book! Since 1989, RGF has been the recognized leader in wash water recycling.

12. How long has RGF been in business?
RGF was incorporated in July 1985 for the purpose of designing, developing, and manufacturing water recycling systems.  Its principles have been in the wastewater, environmental, chemical, engineering, and fabrication businesses an average of 21 years.
13. What is the life expectancy of the RGF OWS and SD? Indefinitely. Basically, the pumps will wear out in time. They can be easily replaced. The rest of the system, in polyethylene and PVC, the RGF Systems are built to last.
14. I hear a lot about ozone. Does RGF use ozone? Ozone is heavy oxygen, which is an oxidizer like chlorine. Ozone is a gas and is highly corrosive. When made and used correctly, ozone can work to oxidize organics. However, many manufacturers use ozone units that are useless. Basically, they don't produce enough ozone, if any at all, to work. Some use ozone with steel or non-UV protected polymers, which will last about six months. Many use corona discharge systems without oxygen generators or air dryers. These last about six months as they create nitric acid. RGF offers ozone with our RGF Turbohydrozone generator. After four years of R&D, we came up with a reliable, tough and efficient ozone generator that will work at a high volume for years, without maintenance. The Turbohydrozone combines UV light and ozone to create a catalytic oxidation faster and more powerful than ozone or chlorine.
