Chromium effects of tannery waste water and appraisal of toxicity strength reduction and alternative treatment

<p>Tannery waste waters decrease the quality of water bodies into which they are discharged is of large scale<br>environmental concern. Disposition of tanning effluents e.g. Chromium (Cr) into the environment creates<br>inauspicious outcomes by modifying the normal physiochemical properties of soil and water. It is determined<br>that Chromium is the principal threat whenever tanning industry derives in to practice. Cr is extremely venomous<br>and carcinogenic to humankind, animals, vegetations and as well overall environment. The paper was executed<br>solely on secondary information by conferring literature informants including scientific journals, conference<br>articles document and internet site that focused on the effects of tannery waste water and assessment of<br>alternative treatment options used to reduce, removal, retrieve or reprocess Cr from the waste water. Effective<br>management of tannery effluent is the need of the hour. Although a lot of treatment alternatives were assessed to<br>preclude its effect on the environment, neither of them forced out Cr completely. In some cases researchers<br>however successful enough practicing biotechnological methods to reduce the strength and fatal state of<br>Chromium (e.g., Cr(Vl)). Hence, treatment alternatives are either; complex, energy consuming, expensive or<br>applicable to a indisputable portions of the world due to engineering science or proficient work force<br>requirement. Consequently, to tackle these important challenge demanding environmental ordinance with<br>jurisprudence implementation has to be practiced to apply improve treatment scheme which is widely<br>applicatory. Defilers must acknowledge the environmental cost of their manufacture and treated according to<br>polluter pay or precaution precepts. Furthermore, the general public has to be aware of it and all concerned<br>organizations and authorities have to work hard to accomplish zero discharge level or leastwise to gain the<br>standard limit of Chromium discharge defined/ accorded by Environmental Protection Agency.
