Description T-8622
The volume of waste water generated by domestic, industrial and commercial
sources has increased with population, urbanization, improved living conditions, and
economic development. The productive use of wastewater has also increased, as millions
of small-scale farmers in urban and peri urban areas of developing countries depend on
wastewater or polluted water sources to irrigate high- value edible crops for urban
markets, often as they have no alternative sources of irrigation water. Wastewater use for
the irrigation purpose has been well documented but still there are loopholes in the study
to monitor the effects of municipal wastewater on environment and its suitability for
agriculture. Hence, the present investigation was primarily aimed at determination of
agriculturally significant physico-chemical parameters of IARI sewage wastewater and
industrial wastewater from CETP, Mayapuri and compared their pollution strength,
primarily in terms of BOD, COD, TDS, heavy metals and nutrients (N, P, K). The treated
wastewater from CETP, Mayapuri has very excellent prospective for irrigation as the
most agriculturally significant physico-chemical parameters are under the general
standards of FAO guidelines and indicate fairly out of harm's way for the use in
irrigation. However, the sewage wastewater of IARI was not safe and sound and required
further amelioration before its utilization in irrigation. The TDS of the IARI wastewater
was in the range of 1938 – 2220 ppm. The lead (Pb) concentration was also in the range
of 0.04 to 3.84 which is higher side and must be remediated before its utilization to the
leafy vegetable crops. Moreover; the wastewater of CETP was tertiary treated while the
wastewater of IARI was only preliminary treated.
