Hazardous waste falls into many categories. One basic categorization of waste is that which is produced in liquid form. For an example of what liquid waste is, the US Environmental Protection Agency (EPA) states that any material that can pass through a .045 micron filter at a pressure differential of 75 psi is considered to be liquid waste. That’s a very technical explanation, of course. On the other hand, it is too simplistic to say, you’ll know liquid waste when you see it.
Almost every industrial enterprise generates some form of liquid waste. There are various rules and regulations for it proper storage, transport and disposal according to local, federal and state law. New Jersey State regulations may vary from neighboring states, and companies operating within its borders must comply with individual state laws.
Waste water is any water that has been altered by humans. The water found in sewer systems would be waste water. Industrial waste water is produced by the food, iron, steel, pulp and paper industries. Some of these materials may require separation by centrifugation before part of the material will fit the above definition as liquid waste.
Liquid waste can include oil and oily water which requires separation. Fats, oils and grease as a byproduct of the food industry are also considered to be liquid wastes. Waste from septic systems, portable toilets and other sanitary systems also fall into this category.
Liquid waste containers are available in various sized cans and barrels and made with materials such as metal and plastic. There are regulations and guidelines at local, state and federal levels to ensure the proper storage, transport and disposal of waste water.
