1. New structure advantages:
a) cted Structure in horizontal with covers in both ends to resistant the pressure
b) automatic control without needs of operator site monitoring in 24 hours
c) internal "MBR" technology to have impact structure to match limited space of cabin.
d) the intermittent aeration in bio-membrane tank and hollow fiber membrane tank, form the process of "aerobic anoxic", and resolve the problem of "nitrogen and phosphorus removal".
e) by using "air-lifting" way to transfer the sludge from sediment tank and membrane tank to aeration tank, pump stopped without cutting air supplying, the dirt scale on the membrane come down. The life of membrane can be prolonged at least 8 to 9 years by back flushing and on line clean the membrane patent.
f) the online clean technology also avoid the problem of manual opening and cleaning, as well as replacing the membrane in the narrow space.
-Performance
1) Average Sewage disposal capacity Liters/day: from 840 to 30,800
2) Discharged water Spec. (comparing with Standard of Old, USCG and Alaska)
Convention Discharge Standard | IMO Old standard | IMO New standard | USCG | Alaska |
TSS (mg/l) | <50 | <35 | <150 | <30 |
BOD5 (mg/l) | <50 | <25 | N/A | <30 |
COD (mg/l) | N/A | <125 | N/A | N/A |
Coliform (pcs/100ml) | <250 | <100 | <200 | <20 |
PH | 6~9 | 6~8.5 | N/A | 6~9 |
Remaining Cl (mg/l) | N/A | <0.5 | N/A | 10 |
Type test (days) | 10 | 10 | 10 | 30 |
3) Capability of disposed sewage:
a) Black water: excrement and urinefrom toilet
b) Gray Water: waste water form cooking room and bath room
4) It Can be developed to a sewage recycling system
-Application field
1) Fitting to ships building since Jan.1st.2010
2) For small hotels sewage treatment
3) For disposal sewage from port, drilling platform
4) For sewage recycle system in water shortage area such as desert, sea
