Buy plant for waste water treatment ORCA III

Manufacturer - EVAC (Finland)

ORCA III is a plant for waste water treatment of physical-chemical type.
Complies with all requirements of IMO Resolution MEPC.159(55)

System description:
During the operation waste waters are collected in holding tank of the vessel and then flow to ORCA III plant by means of the transfer macerator pump. Flocculant is added by the dosing pump to waste water pipe before transfer macerator pump. Coagulate is intensively mixed with waste waters by means of static mixer and continues as slow mixing in sedimentation tank. Water flowing from sedimentation tank fills in the oxidizing tank up to a defined level. After the level is reached, recirculation discharge pump pumps water through the disc filter. Inside the oxidizing tank oxygenated water is mixed with sodium hypochlorite to create oxidizing/disinfecting substance recirculating in a defined time moment. Then the treated water is discharged overboard by means of recirculation discharge pump through the 3-way valve. Waste waters treated by ORCA III possess quality allowed for discharge.

Standards compliance:

Has sanitation-epidemiological certificates
Complies with all requirements of IMO MEPC.159(55)
