Polishing Filtration/Recycling with Oil Removal
HE/5000
PLC & touch screen that provides factory remote system monitoring and reporting of any connected devices.
HE/5000 filtration system is designed to filter wash water for recycling back to wash applications or for sewer discharge. Systems are configured with two integrated process tanks that improve the waste stream as it is pumped or gravity fed through the filtration processes.
Wash water first enters the first process tank for oil coalescing. Liquid flows vertically downward through a quiescent feed tube to promote particle separation at tank bottom before being directed vertically upward into an oversized oil coalescing pack. As liquid ascends through the coalescing pack, flow direction is continuously changed to ensure microscopic oil droplets contact and adhere to coalescing pack's surface to form larger droplets. These larger coalesced droplets then float to the surface where they are skimmed.
Skimmed oil is captured in a decanter where oil is again separated from wash water and gravity drained to a waste oil receptacle.
Clarified liquid then flows into the polishing loop process tank. The polishing loop includes a high-volume pump, air injection system and media filter. Wash water circulates at a rate of about 100 GPM through the media filter and back to a process tank to ensure optimal solids removal. Media filter uses one of several application specific media types that target contaminates in the waste stream to maximize filtration performance.
The polishing loop can be fitted with optional equipment if odor control, foam control or pH adjustment is required. Up to 12 GPM of filtered wash water can be delivered to wash applications or discharged to sewer. The integrated PLC controls and monitors system operation and promotes optimum performance.
