Every distributor is designed to ensure low maintenance, provide energy efficiency, and deliver consistent performance that result in lower power and maintenance costs, and years or trouble free operation.

Trickling Filter Media – Brentwood

Brentwood Trickling Filter Media is a structured-sheet media that is largely responsible for the success of performing trickling filters. Unlike outdated rock fill, PVC modules have superior compressive strength and higher void volumes, which are necessary for stacking. Greater specific surface area allows for higher organic loadings and process efficiencies. All Brentwood trickling filter media is fabricated from rigid, self-extinguishing, un-plasticized PVC sheets with UV protection. The material is resistant to rot, fungi, bacteria, acids, and alkalis commonly found in wastewater.
