Abstract
A method and system for the recuperation of the content of septic tank where the supernatant is returned to the septic tank after the recuperation of the sludge and of the scum is described herein. According to the method of the present invention, a major portion of the supernatant is advantageously recuperated from the top of the septic tank to the bottom thereof, and stored in a first reservoir of the system. The sludge, the remainder of the supernatant and the scum are then recuperated and stored in a second reservoir. The supernatant is filtered, either upon its recuperation or before its return to the septic tank. Finally, the filtered supernatant is returned to the septic tank.
Claims29
A method for the recuperation of septic tank content using a mobile recuperation unit having first and second reservoirs, the content of the septic tank including sludge, supernatant and scum, said method comprising:
- transferring a portion of the supernatant from the septic tank to the first reservoir of the mobile recuperation unit;
- transferring the remainder of the content of the septic tank into the second reservoir of the mobile recuperation unit;
- filtering the supernatant;
- and
- transferring the filtered supernatant from the first reservoir back to the septic tank.
A system for the recuperation of septic tank content including sludge, supernatant and scum, said system comprising:
- a first reservoir;
- a second reservoir;
- a bidirectional pump assembly having at least one pump suction pipe having a proximate end connected to a first port thereof;
- said pump assembly having a second port connected to said first reservoir and a third port connected to said second reservoir;
- a filtering assembly provided between said second port and said first reservoir;
- and control means whereby, said bidirectional pump assembly pumps the supernatant from the septic tank into said first reservoir, filters this supernatant via said filtering assembly, pumps the sludge and the scum to said second reservoir and pumps back the filtered supernatant to the septic tank to thereby reduce the portion of the content of the septic tank remaining in the recuperation system.
A system for the recuperation of septic tank content including sludge, supernatant and scum, said system comprising:
- a first reservoir;
- a first pump having an inlet and an outlet open to said first reservoir;
- a first pump suction pipe having a proximate end connected to said inlet of said first pump;
- a filtering assembly associated with said first pump suction pipe;
- a second reservoir;
- a second pump having an inlet and an outlet open to said second reservoir;
- a second pump suction pipe having a proximate end connected to said inlet of said second pump;
- and control means whereby, a) said first pump pumps the supernatant from the septic tank to said first reservoir, b) said filtering assembly filters the pumped supernatant, c) said second pump pumps the sludge and the scum to said second reservoir, and d) said first pump pumps back the filtered supernatant to the septic tank to thereby reduce the portion of the content of the septic tank remaining in the recuperation system.
