1. Marine Wastewater Treatment Unit Main Spare Parts:

(1) Air Pump

Air pump is used for transporting air to the plant. The plant is equipped with two kinds of air pump, they are main air pump and lifting air pump. They have the same structure but different functions. The main air pump is used to aerate to aeration tank and contact oxidation tank. The lifting air pump is used to lift the sludge in membrane tank and setting tank to aeration tank and to aerate to membrane tank.

(2) Cutting And Discharge Pump

Cutting and discharge pump is the open impeller centrifugal pump, the sewage is cut and macerated by cutting pump to recycle or discharge it to overboard at the emergency time. The sewage in all tanks can be discharged empty, so long as open the cerresponding bottom valves.

(3) Selfpriming Pump

Self-priming pump is a centrifugal pump with stronger ability of self-suction, but it is better to keep some water in the pipes to avoid the problem for restarting. It can create a certain difference pressure and make the water permeate the membrane.

(4) Ultraviolet Ray Sterilizer

The disinfection principle of ultraviolet ray sterilization is to adopt appropriate length of UV wave to damage the molecular structure of the DNA or RNA of organism cell. It causes the deaths of growing cell and regenerative cells and makes content of coil form in effluent meet the requirement of discharge standard.

(5) Electric Control Box

The electric box is provided with the function of electric operation, protection and procedure control for the equipment.

2. Marine Wastewater Treatment Unit Process Principle:

The device 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. The treatment procedures of the plants are shown as following:

3. Marine Sewage Treatment Plant Severl Class Certificates Supply:

ABS, BV, DNV.GL, LR, RINA, NK, USCG, and CCS class certificates.
