B

  • Best Management Practices (BMP): BMP are scheduled activities, prohibitions of practices, maintenance procedures and other management practices to prevent or reduce pollution.
  • Builders: Builder’s primary function is to reduce the water’s hardness. They work on the main contributors in hard water, calcium and magnesium, by precipitation or chelation (holding these minerals in suspension), allowing the surfactants (cleaning agents) to penetrate more effectively.

C

  • Colloidal Matter: Matter that is finely divided and will not settle.
  • Conversions
    • 4,608 Drops (approximately) = 1 Gallon
    • 1 Gallon = 8.34 Pounds
    • 1 Cubic Foot = 62.4 Pounds
    • 1 Acre Foot = 325,851 Gallons
    • 1 Gallon = 3.785 Liters
    • 1 Cubic Foot = 7.48 Gallons
    • 1 Milligram Per Liter (mg/l) = 1 Part Per Million (ppm)

E

  • E. coli (Escherichia coli): A species of bacteria found in large numbers in the intestinal tract of warm-blooded animals.

I

  • Ion: A charged atom, molecule, or radical that affects the transport of electricity through an electrolyte. An atom or molecule that has lost or gained one or more electrons.

P

  • Parts Per Million (ppm) or Milligrams Per Liter (mg/l): Parts per million (ppm) is for volume and milligrams per liter (mg/l) is for weight per volume. They both are used as measurements of parts, contained in the whole. Here is an example of ppm: If you had one blue marble mixed in with 999,999 clear marbles, you would have 1 ppm or if you used the weight of that one marble, it would be 1 mg/l. Both are used in water and wastewater treatment and are interchanged in conversations, but they are one in the same.
  • Preliminary Effluent Limitations (PELs): Means effluent limitations developed by the Division, or developed by the applicant and approved by the Division, that will serve as the effluent quality guidance for the alternative treatment facilities identified in the site location application and the selected alternative for the final design of the domestic wastewater treatment plant. PELs are determined for the proposed discharge flow and are set at a level such that the proposed treatment facility will not cause an exceedance of applicable water quality standards for those state waters to which the proposed discharge would be made.
  • Protein: A class of nitrogenous organic compounds that consist of large molecules composed of one or more long chains of amino acids and are essential part of all living organisms, especially as structural components of body tissues such as muscle, hair, collagen, etc. and as enzymes and antibodies.

S

  • Surfactant: Surfactants are organic chemicals that are used to release the binding properties of water and allow cleaning agents to penetrate, loosen and remove grime and soil from clothing. There are different classifications based on their ionic (electrical charge) properties in water. The application of these different classifications varies from laundry detergents, to household cleaners and hand soaps.

T

  • Total Dissolved Solids: Total Dissolved Solids (TDS) is the measure of dissolved material in a liquid. For a better understanding of TDS, put a teaspoon of salt into a glass of water. Watch as the salt starts to dissolve. The dissolved salt at this point is considered a dissolved solid. Now apply that picture to the natural world. Water is dissolving deposits of various sizes from large to minute particles contained in the earth’s soil, like calcium, sodium, magnesium, sulfate, chloride and potassium.

V

  • Virus: A genetic element containing either DNA or RNA that replicates in cells but is characterized by having an extracellular state.
