The Spectrum Filter achieves a high level of performance by using two particulate media layers and a patented backwash process. The upper layer of coarse media allows for an extended service cycle by providing depth filtration of large particles while a lower layer of proprietary, very dense fine polishing media provides surface filtration for smaller particles.

The Spectrum Plus Filter achieves a high level of performance by using two particulate media layers and a patented backwash process. The upper layer of coarse media allows for an extended service cycle by providing depth filtration of large particles while a lower layer of proprietary, very dense fine polishing media provides surface filtration for smaller particles. This filter is designed to treat produced water and reduce oil and solids content prior to use in downstream oil & gas operations.
