Reverse Osmosis Desalination Technology in the Oil & Gas Industry

RO desalination

Offshore industry needs for potable water

Offshore platforms are located in some of the most remote, inhospitable environments on the planet. At any given moment, more than two hundred people may be living and working on a platform, each requiring gallons of potable water for diet and sanitation. Freshwater is also required for operations aboard a platform. In fact, the main ingredient in most oil and gas industry operations is freshwater, but shipping this invaluable asset to offshore platforms is prohibitively expensive and inefficient.

On-site water purification solves this problem by allowing platforms to generate their own potable water from high salinity seawater and brackish water. One of the most reliable forms of water purification for offshore production is reverse osmosis. MECO’s RO plants equip offshore platforms to produce water quality at well below 500 parts per million in a single pass.

Reverse osmosis desalination technology

Seawater reverse osmosis (SWRO) has been the favored water purification technology for the oil and gas industry for decades due to its low energy consumption. In SWRO, seawater or brackish water is forced through a semipermeable membrane. Salt and other contaminants are retained on the pressurized side of the membrane while pure water is allowed to pass through.

MECO’s MMRO product line

MECO has been producing SWRO systems for the offshore oil and gas industry for more than forty years. Today, our MMRO reverse osmosis plants provide clean water for marine operations around the world. Our streamlined designs are engineered for ease of installation and operation and for long-term reliability, and our wide range of standard unit sizes and modular construction allow customized output and configuration. The table below shows a cross-section of our 20 models to offer perspective on the range of capacities available.
