Biological treatment of wastewater: sustainable solutions for maritime and offshore applications The biological treatment of wastewater is increasingly recognised as the most sustainable and effective way to address the unique challenges of marine and offshore environments. As regulations tighten and environmental concerns intensify, shipowners and operators are turning to advanced Bioreactors to improve compliance,… Read more

Choosing the right sewage treatment plant for ships: what to look for As the maritime industry faces increasingly stringent environmental standards and operational demands, selecting the right sewage treatment plant on ships has become a critical decision for shipowners and operators. With a broad range of options available, understanding the essential considerations can help ensure… Read more

Flexible retrofit solutions for water treatment on offshore platforms Reliable water treatment on offshore platforms is essential for operational continuity, crew safety, and environmental compliance. As offshore sites evolve, either through expansion or changing crew capacity, the ability to upgrade or retrofit wastewater treatment systems becomes a decisive factor in maintaining these standards, without introducing… Read more

Biological treatment of wastewater: Enhancing vessel wastewater management The biological treatment of wastewater is a vital component of modern marine waste water management strategies. As regulatory pressure increases and environmental awareness grows, shipowners are looking towards integrating advanced solutions such as bioreactors and marine incinerators for optimal compliance and efficiency. At G&O Bioreactors, we recognise… Read more

What is a biological sewage treatment plant – and why choose one? In the maritime and offshore industries, efficient wastewater management is essential for both operational compliance and environmental protection. A biological sewage treatment plant – also known as a bioreactor for wastewater treatment – offers a proven solution, utilising the natural degradation of organic… Read more

Membrane bioreactor for wastewater treatment in marine applications As regulatory pressure on marine wastewater discharge increases, shipowners require robust, future-proof solutions for biological wastewater treatment. Traditional Moving Bed Biofilm Reactor (MBBR) systems have been widely used, but the membrane bioreactor process (MBR) offers significant advantages in terms of discharge quality and operational safety. How a… Read more

On July 1st, 2025, Finland implemented the world’s first nationwide regulation requiring all vessels, regardless of type, to meet stricter standards for onboard wastewater treatment. This legislative milestone marks a growing trend: environmental compliance in maritime operations is no longer optional—it’s essential. The implications for shipowners Finland’s legislation signals an accelerated tightening of wastewater discharge… Read more

Even in tiny amounts, chlorine is highly toxic to fish and other aquatic life. Trout larvae die at concentrations as low as 0.006 mg/L, and at just 0.1 mg/L, most marine plankton are killed. Once released, chlorine can also react with organic matter in seawater to form trihalomethanes (THMs) – a group of persistent, carcinogenic… Read more

Whether operating under strict IMO standards or working with NATO-aligned navies, regulatory compliance is at the core of every system we deliver. Our Bioreactors hold MED and IMO MEPC 227(64) certificates, and our systems are designed to meet the highest global standards for onboard wastewater treatment regardless of vessel type or operating environment. “Navigating the… Read more

What is Biological Wastewater Treatment? Biological wastewater treatment is a process that uses microorganisms to break down organic matter in sewage. This method is effective in removing contaminants from water, making it suitable for discharge into the environment. The process of biological water treatment involves three primary stages: 1. Pre-treatment (Screening Phase) Water is first… Read more
