Project Overview
Textile effluent treatment is typically managed with flocculation and aeration, which require heavy chemical use, electricity, and generate large sludge volumes. For dyeing and bleaching units in Perundurai, this leads to high operating costs and environmental concerns.
BEADS™ Technology Solution
Bio-Electrochemical Anaerobic Digestor System (BEADS™) developed by JSP Enviro provides a sustainable alternative:
Recovers Energy
Anaerobic fuel cell-based process that treats wastewater while generating electricity or methane.
No Chemicals & Minimal Sludge.
No chemicals required for treatment. Upto 80% reduction in sludge.
Modular Design
No concrete structure required. Modules can be added as capacity increases.
