  1. 3. A buildup of particulates on or within a filter, preventing fluid flow through the filter at normal pressures.
  2. 7. Flow coefficient
  3. 8. Wastewater or water flows that are often treated separately then fed into the main process;
  4. 9. Type of filter where wastewater flows over media and enables the formation of slimes or biomass, which contain organisms that feed upon and remove wastes from the water being treated.
  5. 11. The process of removing minerals from water, usually through
  6. 14. A chemical produced by living cells having the ability to reduce large organic molecules to units small enough to diffuse through the cell membrane.
  7. 15. A term applied to a dewatered residue from a filter, centrifuge or other dewatering device.
  8. 16. A deposit or precipitate of magnesium ammonium phosphate hexahydrate found in digested sludge lines, valves, centrifuges and centrate discharge lines
  9. 18. The name of the table that arranges the elements in order of increasing atomic number that illustrates the repetition (or periodicity) of the key characteristics.
  10. 19. The liquid overlying the sludge layer in a sedimentation vessel
  11. 20. A quarter-turn manual valve that uses a cylindrical or tapered plug to permit or prevent straight through flow through the body.
  12. 22. A unit of length indicated by the symbol A.
  13. 23. A test procedure where a chemical solution of known strength is added drop-by-drop until a certain color change, precipitate or pH change in the sample is observed (end point).
  14. 24. A mechanical treatment process that cuts large pieces of waste into smaller pieces so they will not plug pipes or damage equipment.
  15. 25. Water treatment equipment that uses a sodium-based ion exchange resin principally to remove calcium and magnesium cations.
  16. 26. A spillover device used to measure or control water flow.

  1. 1. A type of valve that is a linear-motion valve characterized by a round style body with a long face-to-face dimension.
  2. 2. The movement of water into and through a soil and into underground infrastructure.
  3. 4. To separate water from sludge to produce a cake that can be handled as a solid
  4. 5. A property of water, or any other fluid, that resists efforts to change its shape or flow. Some fluids are rated by how thick it is.
  5. 6. reverse osmosis or distillation.
  6. 10. The membrane output stream that contains water rejected by the membrane.
  7. 12. Dialysis conducted with the aid of an electromotive force applied to electrodes adjacent to both sides of the membrane.
  8. 13. Any of several derivatives of methane in which three halogen atoms (chlorine, bromine or iodine) are substituted for three hydrogen atoms.
  9. 17. Any process that upgrades treated wastewater to meet specific reuse requirements. Also called advanced waste treatment.
  10. 20. The proportion of the total volume of material that consists of pore space or voids, usually stated as a percentage.
  11. 21. A device for measuring fluid flow, including a short converging cone succeeded on the same axis by a long diverging cone.
