Grey Water Management

Key Considerations for Grey Water Management in Marine Settings

Marine grey water is the wastewater generated on boats, ships, and other vessels. With increasing numbers of vessels on the water, proper management of this waste is becoming a growing concern. Traditional treatment methods are often expensive and unsustainable, making it important to explore alternative solutions. One such solution is the use of active bacteria for marine grey water treatment.

Active bacteria have several advantages when it comes to treating marine grey water. They are cost-effective, environmentally friendly, and can handle a wide range of waste streams. Additionally, bacteria-based systems are easy to set up and monitor, making them a great option for marine environments.
