Look inside the EcoBELT

EcoBELT™ removes solids using a continuous-loop fine mesh belt screen. As the screen moves it acts as a conveyor and carries solids out of the incoming wastewater. The patent-pending cleaning system discharges the solids from the belt screen and deposits them into the screenings hopper. Periodic hot-water flushes further clean the belt screen by removing oil and grease that may accumulate over time. An optional screw press dewaters the collected screenings to between 20-40% dry solids while screened wastewater continuously passes through the unit.

How does it save energy? Where other RBFs use a air-based belt cleaning device that must run a high-energy blower constantly; the EcoBELT’s Doctor Blade is a mechanical solution taking advantage of the momentum of solids on the belt. It uses no additional energy and saves up to 80% of the system’s overall energy input when compared to similar filters.

Quick question:

How long does a belt last?

Belts used in the EcoBELT are specially-designed to last twice as long as many of its competing belts. While impacted by factors including types of pretreatment in the plant configuration and belt loading, belts last 2 years on average. And though belt replacement is infrequently required, the EcoBELT is designed to make it a smooth exercise for plant operators. Nexom's team trains operators to swap out the EcoBELT belt in 30 minutes (other RBFs take 6-8 hours). Don’t risk having another RBF’s belt fail during peak flows; with EcoBELT you’ll be back online 16x faster!
