Abstract
A horizontally-extending shear tank having a plurality of blades spaced along a horizontally extending elongated shaft disposed in the tank for shearing floc in a water treatment system. A method of collecting a swath magnetic floc, transferring the floc to the horizontally-extending shear tank, shearing magnetic seed from the floc to produce a slurry swath, and transferring the slurry swath to a magnetic device to separate the magnetic seed for recycling.
Claims25
A water treatment system for treating water including seeded floc, comprising:
- a. a horizontally disposed collector for collecting the seeded floc;
- b. a horizontally extending shear tank for receiving the seeded floc from the collector and shearing the seeded floc to produce a sheared slurry of seeds and sludge;
- and
- c. the horizontally extending shear tank including:
- i. a horizontally-extending tank;
- ii. a horizontally disposed shearing device mounted in the horizontally extending tank;
- and
- iii. an outlet formed in the horizontally extending tank for discharging the sheared slurry of seeds and sludge.
A method of treating water containing seeded floc, comprising:
- a. collecting the seeded floc on a collector;
- b. removing the seeded floc from the collector;
- c. directing the seeded floc into a horizontally-extending shear tank;
- d. shearing the seeded floc in the horizontally-extending shear tank to produce a sheared slurry of seeds and sludge;
- and
- e. discharging the sheared slurry of seeds and sludge from the horizontally-extending shear tank.
A method of treating water containing floc seeded with magnetic seeds, comprising:
- a. feeding a first swath of floc into an inlet of a horizontally-extending shear tank;
- b. shearing the floc in the horizontally-extending shear tank by contacting the floc with a plurality of moving blades connected to an elongated shaft disposed horizontally in the horizontally-extending shear tank, producing a sheared slurry of magnetic seeds and sludge;
- c. feeding a second swath of magnetic seeds and sludge from the horizontally-extending shear tank to a rotating magnetic collector to extract the magnetic seeds from the sludge;
- and
- d. feeding the magnetic seeds to a flocculation tank and discharging the sludge.
