One of the industry’s top digital network integrators, STL, announced today that all of its manufacturing facilities in India have received Deutsch Quality Systems’ Zero Liquid Discharge (ZLD) certification (DQS India).
Achieving “Water Positivity by 2030” is one of STL’s UN SDGs, and this is a significant step in that direction.
India currently only possesses 4% of the world’s freshwater reserves, but by 2025, demand will increase by almost 70%, placing unprecedented strain on water supply chains.
Water management is at the top of the list for STL’s materiality matrix.
Due to this, STL is creating communities that are water-resistant and implementing technology solutions like rainwater harvesting to better manage water demand and adhere to strict ZLD guidelines.
Sewage (STP), Effluent Treatment (ETP), and Multi-Effective Evaporator (MEE) plants are used at STL to control water.
The ZLD procedure entails in-plant improvements to reduce water usage and a thorough study of the liquid waste profiles. Chlorine and solids are removed from the effluent chemically.
Following a three-tiered centrifugation process to remove salt and suspended materials, it is suitable for scrubbers and boilers.
A Supervisory Control and Data Acquisition (SCADA) architecture and shift dashboards are used to monitor the entire process digitally.
For all six manufacturing facilities located in Aurangabad and Silvassa, Maharashtra, India, STL has successfully replicated the ZLD structure.
In total, these actions helped STL recycle more than 145,000 cubic meters of production wastewater across all of its manufacturing plants in FY22.
Akanksha Sharma, Global ESG Head, STL, commented on the accomplishment, saying, “Water conservation and reuse are top of the agendas of the organizations subscribing to sustainable business practices.
The ZLD accreditation for all of our manufacturing facilities in India demonstrates our view that it is possible to preserve water and use it again while conducting sustainable business practices.
