Abstract
A system and process for utilizing a magnetic separation technique in a batch treatment process to clarify water. The system includes a tank, a mixing device, a shearing device and magnets. Water held in the tank includes magnetic floc having magnetic seed incorporated therein. The magnetic floc settle in a lower portion of the tank and clarified water is decanted from the tank. A shearing device shears the magnetic floc producing magnetic seed and sludge. A magnetic field retains the magnetic seed while the sludge is discharged from the tank. The retained magnetic seed are reused in subsequent batches of water.
Claims20
A method of removing solids from water comprising:
- a. mixing magnetic seed, a flocculant and water in a tank to form magnetic floc;
- b. settling the magnetic floc in a lower portion of the tank;
- c. decanting purified water from the tank;
- d. shearing magnetic floc in the lower portion of the tank, producing magnetic seed and sludge;
- and
- e. magnetically retaining magnetic seed in lower portion of the tank while discharging the sludge from the tank.
A batch type water treatment system that utilizes magnetic separation to clarify water, the system comprising:
- a. a tank for holding the water to be treated wherein the water includes magnetic floc having magnetic seed incorporated therein;
- b. at least one mixing device disposed in the tank;
- c. at least one shearing device disposed in the tank;
- and
- d. one or more magnets disposed adjacent a lower portion of the tank for attracting magnetic seed to the lower portion of the tank.
