Abstract

A system and process for utilizing magnetic seeding and separation in a water treatment system. The invention relates to the use of magnetic seeding and separation technology where a magnetic seed is added to water along with a flocculating polymer. The flocculating polymer binds the non magnetic pollutant particles to the magnetic seed yielding magnetic floc. Collectors with magnetized surfaces attract magnetic floc. The magnetically collected magnetic floc are sheared to form sludge, which is discharged as waste, and cleaned magnetic seed, which is recycled and reused in the water treatment system. Magnetic seeding and magnetic separation technology are employed in various types of water treatment systems to remove dissolved pollutants, suspended solids and scalants. Moreover, using magnetic seeding and magnetic separation in conjunction with polymers or biological treatment to remove dissolved pollutants and suspended solids from water.
