Revitalization of Rivers In India
Draft Policy Recommendation
of H-acid generates 25 kg of hazardous aqueous effluent stream.
Using Recycle@Source, it has been possible to recycle this mother
liquor back into the process to dilute the reaction mass obtained after
fusion more than 15 times, which reduced the effluent load by 90%.
The mother liquor obtained after isolation is taken for treatment with
a catalyst selectively to remove undesired impurities, then recycled
back into the process instead of water. This solution gives an overall
10% rise in yield. Even after 15 recycles, the quality of H-acid is
consistently as per the standards.
(d) INTACH’s Bacterial Bio-remediation (Manu Bhatnagar, INTACH, 2017)
bacterial bioremediation process, applied on a polluted flowing river
itself, using a combination of dosing of anaerobic bacteria and floating
and submerged media has been piloted by Indian National Trust for Art &
Cultural Heritage (INTACH) on a stretch of the Assi River near Varanasi.
The 3.5 km long Assi river flows through some very densely populated builtup
areas directly discharging wastewater and dumping garbage, including
carcasses, directly into the river. The entire stretch has also been severely
encroached.
The discharge in the river is estimated to be between 65 to 70 MLD. The
water is fast flowing owing to the elevation difference of 27m between origin
and river level.
The interventions undertaken were as follows:
(i)
(ii)
Dosing of Bacteria Concentrates: Naturally occurring, anaerobic and
facultative live bacterial strains (100 litres of concentrate per day
dosed into the stream at 6 carefully selected locations). The bacteria
degrades organic pollutants, enhances dissolved oxygen levels and
removes odours.
Increase retention time by installing soil bag weirs: Create a lagoon
on the upstream side allowing settling and allow for greater retention
period on the otherwise fast flowing stream
