40 Persons Simplified Marine Sewage Treatment Plant

Introduction

The simplified marine sewage treatment plant is used to treat the sewage, which means human waste in toilets, also known as “Black Water”. The Sewage Treatment Plant device is mainly constituted by aeration tank, contact oxidation tank, settling tank, membrane tank, cutting pump, air pump, discharge pump, electric control box, membrane module, UV sterilizer and

accessories of pipe lines.
