The present invention is a floatation process and associated apparatus for removing heavy metal waste from various effluent water streams. The process and apparatus generally introduces a population of fine diameter air bubbles and one or more flocculating chemicals into an effluent stream to produce buoyant floc structures that include the heavy metals and that can be removed from the effluent stream. The present invention provides a reliable, cost-effective means of removing heavy metals from effluent water streams.

The apparatus according to claim 1, further comprising a water sampling adapter fluidly communicating with the flow controlled passage for obtaining water samples. 14. The apparatus according to claim 1, wherein said flow control valve has means for adjusting the flow rate of water through said flow controlled passage. 15. The apparatus according to claim 1, further comprising at least one power source. 16. The apparatus according to claim 15, further comprising a housing for providing protection for at least a portion of the apparatus against factors external to said housing, wherein at least a portion of said power source is disposed within said housing. 17. The apparatus according to claim 15, wherein said power source is a turbine-powered electric generator. 18. The apparatus according to claim 15, wherein said power source is a self-contained power source. 19. The apparatus according to claim 18, wherein said self-contained power source is a battery. 20. The apparatus according to claim 18, wherein said self-contained power source is a rechargeable battery. 21. The apparatus according to claim 15, further comprising at least one supplemental power source for providing supplemental power to said power source. 22. The apparatus according to claim 21, wherein said supplemental power source is a solar cell, battery, rechargeable battery or turbine-powered electric generator. 23. The apparatus according to claim 21, wherein said power source is a turbine-powered electric generator, said electric generator further providing recharging capabilities to said supplemental power source. 24. The apparatus as recited in claim 1, wherein said downwardly discharged pressurized water is received by a drain system. 25. A system for the enhancement of water quality in a subterranean pressurized water distribution system, said system comprising: a subterranean pressurized water distribution system; a drain system; a flow controlled passage for pressurized water having an inlet adapted for fluid connection to a subterranean pressurized water distribution system, said flow controlled passage having a conduit for directing pressurized water received in said inlet to a routing conduit for redirecting said pressurized water subterraneously, said routing conduit having an outlet adapted for fluid connection to said drain system for receiving said pressurized water, whereby atmospheric discharge of said pressurized water and its associated dangers are avoided; a flow control valve disposed along said flow controlled passage for permitting and prohibiting the flow of pressurized water through the flow controlled passage; programmable electronic control circuitry for controlling the flow of pressurized water through said flow controlled passage by activating and deactivating the flow control valve, said system including a programmable microprocessor system for storing instructions for activating and deactivating the flow control valve; and, at least one programming interface operatively connected to the microprocessor for inputting electronic information to be stored and processed in said microprocessor system for activating and deactivating said flow control valve; whereby the apparatus can purge pressurized water subterraneously from a subterranean pressurized water distribution system on an automated, programmed basis to effect desired water flow in said subterranean pressurized water distribution system to control residual levels of contaminants and disinfectants in the water distribution system. 26. The apparatus according to claim 25, wherein said routing conduit extends above ground. 27. The apparatus according to claim 25, further comprising a backflow preventio n device connected between said drain system and said flow control valve for preventing contaminants from entering said subterranean pressurized water distribution system. 28. The apparatus according to claim 27, wherein said backflow prevention device is disposed above ground. 29. The apparatus according to claim 25, wherein said drain system is a storm drain. 30. The apparatus according to claim 25, wherein said drain system is a sewer line. 31. The apparatus according to claim 24, wherein said drain system is a drain field. 32. The apparatus according to claim 24, further comprising at least one power source. 33. The apparatus according to claim 32, further comprising a housing for providing protection for at least a portion of the apparatus against factors external to said housing, wherein at least a portion of said power source is disposed within said housing. 34. The apparatus according to claim 32, wherein said power source is a turbine-powered electric generator. 35. The apparatus according to claim 32, wherein said power source is a self-contained power source. 36. The apparatus according to claim 35, wherein said self-contained power source is a battery. 37. The apparatus according to claim 35, wherein said self-contained power source is a rechargeable battery. 38. The apparatus according to claim 32, further comprising at least one supplemental power source for providing supplemental power to said power source. 39. The apparatus according to claim 38, wherein said supplemental power source is a solar cell, battery, rechargeable battery or turbine-powered electric generator. 40. The apparatus according to claim 38, wherein said power source is a turbine-powered electric generator, said electric generator further providing recharging capabilities to said supplemental power source. 41. An apparatus for the enhancement of water quality in a subterranean pressurized water distribution system, said apparatus comprising: a flow controlled passage for pressurized water having an inlet adapted for fluid connection to said pressurized water distribution system and an outlet positioned for downward discharge to a drain system, said flow controlled passage having a conduit for directing pressurized water received in said inlet to a routing conduit for initially directing said pressurized water upwardly and then redirecting said pressurized water downwardly for downward discharge from said outlet into a drain system entry positioned directly below the downwardly discharging outlet of the flow controlled passage, whereby discharge of said pressurized water upwardly or laterally, and its associated dangers are avoided during purging of the subterranean pressurized water distribution system, said flow controlled passage being free of draining apertures between said inlet and said outlet; a flow control valve disposed along said flow controlled passage for permitting and prohibiting the flow of pressurized water through the flow controlled passage; and programmable electronic control circuitry for controlling the flow of pressurized water through said flow controlled passage by activating and deactivating the flow controlled valve. sequentially separate and deliver compounds within the samples to the detector.
