Lime Softening Water Treatment | Lime Softening Process
Units- Phase 2:
Flow Rate (Softener):
(2) FDB-78P Oil Removal Filters
2,600 gpm (90,000 BPD) (590 m3/hr)
3,450 gpm (120,000 BPD) (780 m3/hr)
Oil removal from water, prior to hot lime softening.
The Deep Bed Filter is implemented in the Oil Removal step (ORF), prior to the lime softening process, and the Softening step (After Filter), post lime softening.
At the site, the oil removal filter influent is between 100 ppm and 300 ppm with an effluent less the 3 ppm oil and solids. After lime softening water treatment, the softener is then used for solids removal and polishing before ion exchange. The softener effluent is consistently less than 1 ppm TSS.
