15 Persons Simplified Black Water Treatment Plant


15 Persons Marine Sewage Treatment Plant

Introduction

The sewage treatment plant is applicable to treat the sewage (human body wastes and wastes from the toilets on vessels, known as black water. It doesn’t add any dilution water, gray water, processing water or seawater. And it’s not suitable for special region like Baltic Sea discharge sewage to the passenger ship, without considering the requirements of the performance index of total nitrogen and total phosphorus.

The type marine 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.

Common Troubles and Solutions

No.

Trouble

Possible cause

Solution

1

Device liquid "to take the tank" and not high alarm

Check the overflow port,if not overflow, the device internal contact oxidation tank to the electric flocculation tank pipeline or overflow port  pipeline blockage.

Clean up the block line

Check the overflow port, if the overflow, then check the control box control

Electrical maintenance

2

High level alarm device

Look at the water meter, such as above rated flow, it is possible to use the peak of the toilet

Temporarily  using the toilet

Look at the water meter, such as below rated flow, the discharge pipeline may not be smooth

Check discharge line

Look at the water meter, such as the rated flow rate, the film may be contaminated.

3

Voice of air pump is

abnormal

Pump failure

Repair or replacement of the pump

The air pump and the electric three-way valve can not be opened simultaneously.

Check control circuit

4

Voice of vacuum pump is

abnormal

The suction is not smooth.

Check line

No water, the membrane may be fouled.

5

One hour without steering electric three-way valve

Sewage or sludge can not be regularly upgrade

Check the control circuit or electric three-way valve

6

UV-lamp is not lighting

UV-lamp is broken

Replace the lamp

7

Water quality is not qualified

Activated sludge is not enough or qualified

Re-culture bacteria

The membrane is out of order

Replace membrane
