Oily Water Treatment Technologies

Oily water is a common waste stream generated by many industries, including oil and gas, marine, and manufacturing. Oily water can contain a range of pollutants, including oil, grease, and other contaminants that can be harmful to the environment and human health.

To ensure compliance with environmental regulations and protect the environment, it is essential to properly treat oily water before discharge.

Oily water treatment technologies are designed to remove oil and other contaminants from water, ensuring that it meets regulatory standards for discharge or reuse. These technologies are crucial in various industries, including oil and gas, petrochemicals, manufacturing, and maritime operations. There are several oily water treatment technologies available, including:

Coalescing technology

Coalescing technology is a widely used method in oily water treatment to facilitate the aggregation of small oil droplets into larger ones, making them easier to separate from water. The process involves the use of coalescing media or devices that encourage the merging of dispersed oil droplets.

The technology involves passing oily water through a coalescer that contains a series of plates or tubes that encourage the oil droplets to come together and form larger droplets that can be easily removed.

Biological treatment

Biological treatment is an environmentally friendly and sustainable approach used in oily water treatment, relying on the activities of bacteria and microorganisms to break down and consume hydrocarbons and metabolize the contaminants present in the water. The technology involves creating a controlled environment that supports the growth of bacteria, which in turn consume the contaminants and produce harmless byproducts.

This process is effective in removing various organic contaminants, including oil and grease, and is commonly employed in wastewater treatment facilities across different industries.

Membrane technology

Membrane technology is a filtration process in oily water treatment that uses a semi-permeable membrane to separate oil and other contaminants from water. The technology is effective for removing both dissolved and suspended contaminants, including oil, grease, and other pollutants.

Membrane technology allows Oily water to pass through the membrane module, which contains the selective membrane material. The membrane acts as a physical barrier, allowing water molecules to pass through while blocking the passage of oil droplets and other contaminants.

Chemical treatment

Chemical treatment is a common and effective method used in oily water treatment to enhance the separation of oil and water phases, as well as to remove or neutralize contaminants. Various chemicals such as coagulants and flocculants are employed to modify the physical and chemical properties of the components in the water, facilitating their separation and subsequent removal. The chemicals cause the oil droplets to come together and form larger droplets that can be easily removed.

Oily water treatment offers several benefits

Environmental Compliance

Treating oily water helps prevent the release of harmful pollutants into natural water bodies, preserving ecosystems and biodiversity.

Protecting Human Health

The treatment of oily water reduces the risk of exposure to hazardous substances for both workers in industrial facilities and the public. Contaminated water can have adverse effects on human health if not properly treated.

Preventing Soil Contamination

Untreated oily water can lead to soil contamination if discharged onto land or if it infiltrates soil. Oily water treatment prevents soil pollution and protects agricultural lands from the harmful effects of oil and contaminants.

Protecting Infrastructure

The presence of oil and contaminants in water can lead to corrosion and degradation of infrastructure such as pipelines, pumps, and equipment. Oily water treatment helps protect industrial infrastructure, extending its lifespan and reducing maintenance costs.

Meeting Industry Standards

Many industries have specific standards and guidelines for water quality. Oily water treatment ensures that water discharged from industrial processes meets or exceeds these standards, demonstrating a commitment to responsible environmental stewardship.
