Refinery Wastewter Treatment Using Constructed Wetlands : Refinery Wastewater Treatment Using Wetlands

With the regular discharge of large volumes of wastewater containing excessive accretions of organics, suspended solids and heavy metals by the Pakistani oil refining industry, over a period of years, major damage has been done to the environment. The deficiency of a wastewater treatment system and a lack of economically viable and sustainability-oriented solutions have exacerbated the extent of environmental impacts that has taken place so far. As the industry in Pakistan has become progressively circumscribed by increased taxation, inconstant as well ever more expensive electrical power supply, and last but not least, stringent environmental laws, there has arisen a strong need for the development of a treatment technology which is sustainable, efficient and cost effective.
