Water that has been adversely affected in quality by pollutants is called waste water. Wastewater treatment means removing biological or chemical waste products from water and then there by treated water can be used for other purpose. Wastewater treatment plants include Agricultural wastewater treatment, Sewage treatment and Industrial wastewater treatment.
Open access to the scientific literature means the removal of barriers (including price barriers) from accessing scholarly work. There are two parallel roads towards open access: Open Access articles and self-archiving. Open Access articles are immediately, freely available on their Web site, a model mostly funded by charges paid by the author (usually through a research grant). The alternative for a researcher is self-archiving (i.e., to publish in a traditional journal, where only subscribers have immediate access, but to make the article available on their personal and/or institutional Web sites (including so-called repositories or archives)), which is a practice allowed by many scholarly journals.
