Oil Platform Sewage Treatment Plant

Oil Platform Sewage Treatment Plant

The oil platform sewage treatment plant used for offshore drilling platform, which be explosion proof type.

The SWCM explosion proof type sewage treatment plant uses activated sludge, contact oxidizing and principle of biologic membrane to digest the organic pollutant, which can treat sewage effectively and reach at the IMO new effluent standard or other stricter requirements.

The plant adopts activated sludge, contact oxidizing and principle of biologic membrane to digest the organic pollutant, which can treat sewage effectively and meet the IMO new effluent standard or other stricter requirements.

It Implement of IMO MEPC.159 (55) Resolution.

The rules and effluent standards as followings:

	IMO old standard	IMO new standard	USCG	Alaska
TSS (mg/l)	50	35	150	30
BOD5 (mg/l)	50	25	NR(Not required)	30
COD (mg/l)	NR(Not required)	125	NR(Not required)	NR(Not required)
Coliform (pc/100ml)	250	100	200	20
PH	6~9	6~8.5	NR(Not required)	6~9
Chlorine (mg/l)	NR(Not required)	＜0.5	NR(Not required)	10
