Ship sewage treatment is an important measure of environmental protection in the shipping industry. With the improvement of people's awareness of environmental protection and the improvement of laws and regulations, the standards of ship sewage treatment are getting higher and higher. Among them, 15ppm is a key standard in ship sewage. What is the meaning of

15ppm? It means that the concentration of grease in water should not exceed 15 mg per liter. This standard is derived from the provisions of the International Maritime Organization (IMO) and aims to protect the marine environment from the effects of oil pollution. When treating sewage, the ship must ensure that the oil content does not exceed 15ppm, otherwise it will be deemed to have violated environmental protection regulations and need to bear corresponding legal responsibilities.

15ppm standard is very important for environmental protection. A large number of ships travel on the ocean every year. If not restricted, the oil pollution will cause great damage to the marine ecosystem. The introduction of the 15ppm standard can effectively reduce the impact of sewage discharged from ships on the marine ecosystem and protect the living environment of marine organisms. The implementation of the

15ppm standard also requires broad support from the international community. At present, most countries have incorporated this standard into laws and regulations, and punished unqualified ships. With the increasing awareness of global environmental protection, more and more countries and regions are gradually improving the standards of ship sewage treatment to better protect the marine environment.

To sum up, 15ppm is an important standard in ship sewage treatment, which is very important to ensure the marine ecological environment and protect human health. We need to further improve the standards of ship sewage treatment by strengthening environmental awareness and technology research and development, and make greater contributions to the protection of our beautiful ocean.
