Spectrum™ Filters
Two Effective Particulate Layers, Higher Level of Performance

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

Simple Package
The Spectrum Filter™’s flow per surface area is two times that of a conventional multi-media filter, resulting in higher productivity, smaller vessel requirement, and a reduction in capital and operating costs.

Proven Reliability
The Spectrum Filter™ outperforms conventional filtration and has proven to extend reverse-osmosis membrane life up to 5 years when used as a pre-filtration system ahead of the reverse-osmosis process.

The Spectrum Filter™ can handle water with a suspended solids concentration in excess of 100 mg/L and provides a filtrate turbidity of less than 0.1 NTU.
