The below is the list of effluent parameters from an industry, can this water be used to grow plants?
COD- 6320 ppm
VFA- 920 ppm
Alkalinity- 1160 mg CaCo3/L
TDS- 2320 ppm
Total hardness- 392
Iron- 4 ppm
Appreciate any one who replies with answer.
I would say it will depends on the type of plants you want to grow. Also for what purpose? Land irrigation, food production for human or animal consumption? Have in mind that if you want to grow plant to be sold for consumption you better analyse your microbial parameters as well.
At first glance, you have a good range of pH, conductivité is high (3.8mS/cm2) meaning that you have alot of conductive ions in your effluent. This is accordance with your TDS (total disolve solid). This shows that your water has alot of minérals good or maybe bad ones? The COD and BOD is also somewhat high meaning that your water contains alot of organic matter, that can be good plants but beware of microbial growth if you too much nitrogen compounds and phosphorous compound in your water and with dissolved oxygen you can promote both algal and bacteria growth (including potential pathogens).
Thank you for your quick reply, i plan on growing a fresh water fern named Azolla, i heard aquatic macrophytes can survive in various organic effluents, so i planted them on a small pond i built, there seems to be slow growth but the plants are alive, phosphorous is deficient in the effluent so i added 6 mg/L of superphosphate and it worked, there seems to be a change in growth.
