Abstract :
Purpose
In Bangladesh, the sludge of textile effluent
treatment plant has been considered as a potential envi-
ronmental threat due to its huge volume and chemical
content. Thus, the present study was carried out to assess
the reuse possibility/potentiality of textile sludge in agri-
cultural applications.
Method
Textile sludge was applied at different loading
ratios (0–100 % sludge) with soil for the pot cultivation of
red amaranth (
Amaranthus gangeticus
); subsequently,
chemical analyses were carried out on the harvested plants.
Results
The results showed that the content of plant
nutrients nitrogen (N), phosphorus (P), potassium (K) and
iron (Fe) in sludge was significant compared to organic
manure along with a high content of total organic carbon
(TOC). The growth parameters (height, number of leaves,
leaf area and root length) of red amaranth were affected by
the application of textile sludge. Maximum plant growth
was observed in the 100 % sludge treatment group, maybe
because of the high content of plant nutrients. However, the
root length and number of leaves were not significantly
affected by the sludge. The plant analyses implied that
addition of textile sludge did not increase the content of
copper (Cu), cobalt (Co), cadmium (Cd), nickel (Ni) and
manganese (Mn), but lead (Pb), chromium (Cr), zinc (Zn)
and iron (Fe) content crossed the maximum permissible
limit set by FAO/WHO.
Conclusion
Textile sludge can improve the nutrient con-
tents of pot soil and growth of red amaranth, which is
revealed by pot experiments. Therefore, it can be used as
soil improver if Pb, Cr, Zn and Fe content can be controlled
in the textile sludge.
