Oil impervious device with high water flow rate
摘要:
A device or method to prevent penetration of oil and petroleum products while allowing high water flow rate is provided. Such device or method is beneficial in controlling the contamination of surrounding soil from accidental leak of hydrocarbons such as oil and other petroleum products from equipment or storage vessels containing such materials. The containment systems equipped with these devices will allow the rain water to flow through while providing barrier to oil and petroleum products.
