Nitrates removal technology for bore well water
Published on by Evans Tembo, Senior TVET Advisor - WASH & Solar Energy - GIZ in Technology
In my project area, we use bore wells as a water source, but recently the water is contaminated by nitrates.
Could you please let me know which low-cost technology can be used to removes nitrates in borehole water in rural areas of a developing country?
Conventional processes for nitrate removal - ion exchange, reverse osmosis and electro dialysis - are quite expensive and pose a question of subsequent disposal of generated nitrate waste brine.
By the Zambian Drinking Water Standard (ZDWS), recommended nitrate levels are 10 mg/l NO3-N equaling 44.3 mg/l NO3.
We would like to reach these levels so any advice is helpful.
