Magnetic Seeding and Separation (MSS) is a high speed magnetic clarification system that removes suspended solids from water. With ballast clarification, fine particles are attached to a heavy material such as sand with a flocculating polymer. This makes the particles heavier and therefore they settle quicker in water.
