Large amount of High-salt wastewater is produced with the oil exploration. The wastewater will severely pollute the environment by disposal and waste so proper measures is need to be taken, so the water can be treated and recycled. Those bring the benefits of saving cost, no harm to the environment, improving economic benefits and successive development.

In consideration of the high-salt wastewater features and practical oilfield production condition, with mature pre-treatment technology and device, we adopt dual-membrane process, we have finished field test and trial verification, which provide a solid foundation for project large-scale implement.
