Traditional ACI Systems

UCC is committed to innovation and technology that deliver performance advantages in our activated carbon injection systems. Our performance-based technology and extensive industry expertise set UCC apart from other suppliers. UCC ensures optimal system performance through sophisticated predictive modeling, on-site trials to validate removal rates, sorbent consumption, balance of plant effects and performance knowledge.


The traditional ACI system is a fully functional, pre-piped and wired skirted silo with equipment installed prior to arrival on site to the maximum extent possible. The silo rooftop equipment includes a bin vent filter, level detector, Hi Hi level detector, and pressure/vacuum relief. The silo is equipped with explosion panels and a truck fill line.

The silo bottom is a chisel with UCC standard fluidizing trays. The feed lines include gravimetric feeders with eductors to meter the material into the conveying line.

Inside the silo skirt, all required equipment is pre-piped and wired including motor starters or MCCs, PLC or DCS junction boxes, transformer, lighting, heating and ventilation, blowers and feed train stackup.
