Researchers at the Environmental Technology Division of the CSIR-National Institute for Interdisciplinary Science and Technology (NIIST) here have developed a bio-eco engineering system for treating greywater.
NIIST is opening a model treatment unit on its campus for treating and recycling greywater from the staff quarters on June 5, in connection with the Environment Day celebrations.
The NIIST system consisted of a modular anaerobic treatment unit (microbial process) integrated into a planted filter bed (Phytoremediation unit) for treating different types of greywater, NIIST said in a statement. The anaerobic treatment unit was a patented design from NIIST. Nearly 50% of the contaminants in the greywater would be removed in the anaerobic treatment system.
