Abstract
Tank designs for magnetic seeding and separation for cleaning water. Magnetic seed are added to water to be treated and form magnetic composite particles or floc comprising the magnetic seed and pollutant particles bound thereto. Moving magnetized surfaces are utilized to collect the magnetic floc from the water to produce cleaned water. The magnetic floc are processed to separate the magnetic seed from a sludge which is ejected. Magnetized surfaces include rotating drums, disks, and walls or panels and moving magnetized belts.
Claims25
A method of treating water utilizing magnetic seeding and magnetic separation, the method comprising:
- mixing magnetic seed and a flocculant with the water to be treated to form magnetic floc;
- collecting the magnetic floc on a magnetic collector that extends a substantial distance around an upper perimeter portion of a tank having the magnetic floc and water being treated therein;
- and removing the magnetic floc from the magnetic collector.
A method of treating water utilizing magnetic seeding and magnetic separation, the method comprising:
- mixing magnetic seed with a flocculant with the water to form magnetic floc;
- submerging an endless magnetized belt in the water;
- driving the endless magnetized belt in the water;
- collecting magnetic floc on the endless magnetized belt submerged in the water as the belt is driven;
- and removing the magnetic floc from the endless magnetized belt.
A water treatment system for treating water by mixing magnetic seed and a flocculant with the water to form magnetic floc, the system comprising:
- a tank for holding the water to be treated and including a surrounding wall structure;
- a mixer disposed in the tank for maintaining the magnetic floc in suspension and moving the magnetic floc in the tank;
- a first magnetic collector disposed adjacent the surrounding wall of the tank and extending around a substantial upper perimeter portion of the tank;
- and the tank having a flocculation zone that is disposed at least partially inwardly of the first magnetic collector such that at least some of the magnetic floc in the tank moves outwardly from the flocculation zone to the first magnetic collector extending around a substantial upper perimeter portion of the tank.
A water treatment system for treating water by mixing magnetic seed and a flocculant with the water to form magnetic floc, the system comprising:
- a tank for holding the water to be treated and including a surrounding wall structure;
- a mixer disposed in the tank for maintaining the magnetic floc in suspension and for moving the magnetic floc in the tank;
- a magnetized endless belt disposed in the tank and configured to be at least partially submerged in the water contained within the tank;
- the tank having a flocculation zone that is disposed adjacent the magnetized endless belt where the magnetic floc is maintained in suspension;
- and a drive for driving the magnetized endless belt such that as the magnetized endless belt is driven, magnetic floc is collected on the magnetized endless belt.
