The use of aquatic macrophytes to treat emerging contaminants in secondary wastewater effluents. Is that possible?
Emerging contaminants like Prescription and non-prescription drugs, Home care products, Veterinary and human antibiotics, Industrial and household products, Sex and steroidal hormones, and other endocrine disrupters.
there is possibility to phytoremediate EDCs, there is also reports titled as PHYTOREMEDIATION OF ENDOCRINE DISRUPTING CHEMICALS IN URBAN RIVER WATER, but the screening of phytoremediating plant species is really time consuming process
phytoremediation can be used to absorb such contaminants in wastewater but you need to carefully select the plant species that will give appreciable absorption efficiency
Hi Akram / Jude,
I'm also interested in the subject, and if you could recommend any particular published studies, could you please post some titles here?
Thanks!
Aquatic plants like lemna (duckweed), typha etc. are known to remove toxic substances from wastewater and can also be used for emerging contaminants. However, further research is needed
You may try Lemna aequinoctialis, Spirodela polyrhiza, Amaranthus gangeticus. Hopefully any of these may work.
Phytoremediation is an excellent technique in wastewater treatment.Lots of literature are available for its high efficency in removing heavy metals The removal efficiency is higher for a single ion (only present) whereas its efficiency decreases when there are other competing ions (actual cases). Therefore the plant may be efficent in removing EDC also if it is under starving condition (with no other alternatives the poor plant will be forced to take EDC as its food).
Dear Phyto R-Researchers, Its very encouraging to note that this field has been doing well and offers a great opportunity to carry out effective remediation. phy-R is ideal for physical, chemical and micro-biological contaminants and pollutants.. The plants in different sp. give a variety of mixes. ie growing in submerged, partially, and on land, floating plantation too is an ideal variation, We need to stress that - the factors that aid phy-R are as follows- sunlight, air with O2, CO2,N2, and also HC minim %, air changes with draft of air, O&M-operation & maintenance practices- de-weeding, When the plant produces are taken up for any human consumption, caution is to be exercised, At best, they can be deep-fried and eaten, ie avoid raw or boiled form, Many forms of plants have been used, and offer ideal remediation by adsorption in soil, stones, roots, stems, leavves, flowers, etc.. PhyR does create an unique eco-system with valued bio-diversity. Even the fish, birds, and others partaking with the bio-assets, contribute to the wwt treatment and process, happening naturally. With well wishes on precise documentation of plants sp. and the remediation done on varied pollutants etc.
