Talk:Vermifiltration
Not well written
[edit]This article is not well written, not using Wikipedia's encyclopedic style. It is more written like some sort of literature review. I propose what can be salvaged is included in the page on vermifilter and the rest is deleted. Instead a redirect is placed from this page to vermifilter.EvMsmile (talk) 13:58, 19 December 2016 (UTC)
I have removed this section as it is only written like a literature review and not encyclopedic:
Industrial treatment
Sinha et al.,(2012a) studied vermifiltration of wastewater obtained from automobile service industry. This wastewater contained a mixture of aliphatic and aromatic volatile hydrocarbons (C10–C36) and organochlorines. The aromatic fraction mainly consisted of PAHs and is more toxic and persistent than the aliphatic part. Earthworms not only tolerated and survived as were also responsible by wastewater treatment. Dhadse et al., (2009) studied the vermifiltration of herbal pharmaceutical wastewater, which has very high BOD5 (11,200-15,660 mg L−1), COD (21,960-26,000 mg L−1) and TSS (5,460-7,370 mg L−1). BOD was removed by 90–96% and COD by 85-94%, using a two-day hydraulic retention time. Heavy metals were also removed and no sludge was formed.
