SOIL MAIN

These are for handling the waste from Water Closets, Urinals and all Hospital waste

water as required by health codes. Inputs from this source not exceed 70

liters/person/day. Overboard by-pass line must be fitted. A Luzhou Transfer Unit can

be fitted if the final soil pipe position is below the sewage treatment plant. Ensure

that peak pumping flows or periods don’t exceed the peak handling capability of the

Sewage Treatment Plant. On Gravity sewage collection system, a Macerator is

recommended with units sized above 150 crews and on passenger vessels and

ferries.

SOIL WATER GRAVITY PIPELINE FALLS

This should be a minimum of 10mm per 300mm run in the direction of flow, after

allowing for the worst trim conditions Non-Return Valves or Valves which could

cause a flow restriction should not be fitted.

AIR VENT

It is important that no liquid pockets can from to impede the free run of the gasses.

Luzhou can supply a centrifugal fan for difficult pipe arrangements. A flame trap is

not required.

EMERGENCY OVERFLOW FROM TREATMENT TANK

This can only be effective when the tank overflows. Connection must be 1.5m above

maximum sea water levels to ensure that the Non-Return Valves can be lifted and

flow take place. If the available is less than this a back-up will occur in the system

until the required head is available. If emergency overflow connection is below

maximum water level then connect to bilge including a ”U” trap of 200mm to prevent

venting into the compartment.

GALLEY WASTE

This should be treated comply with the IMO resolution; normally drain it overboard

directly via a 25mm screen. If it is intended to connect into soil inlet of the sewage

treatment plant, LUZHOU must be consulted, as size of plant will be affected and a

grease trap must be fitted.

NOTE: THE GREY WASTE PIPELINES SHOULD NOT CONNECT TO THE

TREATMENT PLANT.

SIPHON PREVENTION

If the top of the sewage treatment tank is above minimum sea water level, then the

pump discharge pipeline must be looped above the top of the tank and a connection

taken from the top of the loop to a point in the air vent line above the discharge head of

the pump.

MEMBRANE SYSTEM

Pretreatment water (in primary treatment tank) is circulated under the function of

MEMBRANE SYSTEM, and the concentrated water will return to the bioreactor but

the filtrate, accordance with the IMO 159(55) latest regulations, will be collected into

the treatment tank and pumped overboard automatically. The function, BACKWASH

is provided to clean the system with the compress air, 0.4Mpa under the controlling

of El.Control Panel.

DUAL PUMP SET

This can be supplied to give a standby pump ready piped in.

AIR COMPRESSOR

When the sewage plant is offered, the dual air compressors have been installed.
