KRISHNA MATHA
PUSHKARANI (Udupi, Karnataka)

Temple ponds like the Krishna Matha Pushkarani in Udupi hold cultural and ecological significance but face issues like organic waste, low oxygen, algal blooms, and foul odor. To address this, NICO Nanobubble India Pvt. Ltd. implemented its nanobubble aeration technology. This case study highlights the scientific, chemical-free, and energy-efficient approach used to restore water quality and preserve the pond’s sanctity.

Objectives

  • The primary objective is to remove the algae concentration in the pond water and to restore the water bodies.
  • Also, to analyze the changes in the following water parameters:
  • BOD, COD, TSS, E. Coli and DO.

Initial Condition Of Pond

pH 7.15 COD 132.5 mg/L
TDS 197 mg/L DO 5.5 ppm
BOD 25.7 mg/L E. Coli 59.85 MPN/100 mL

How Nanobubbles Restore Lakes And Ponds To Combat Algae

Nanobubble technology offers sustainable lake restoration by delivering efficient oxygenation and chemical-free oxidation. By increasing dissolved oxygen—especially in deeper layers—it limits algae growth, supports beneficial bacteria, and reduces excess nutrients. Nanobubbles also help break down existing algal blooms through natural oxidation, improving water clarity and overall quality.

FINAL CONDITION OF POND

Parameters Units Before Treatment After Treatment
BOD Mg/L 25.7 6.6
COD Mg/L 132.5 33.7
DO PPM 5.5 15
E. Coli MPN/100 mL 59.85 6.75
TDS Mg/L 197 182.5

CONCLUSION

A case study conducted by NICO Nanobubble India Co. at the Krishna Matha Pushkarani pond demonstrated the remarkable efficacy of nanobubble technology in restoring and maintaining water quality in a culturally and environmentally sensitive setting.
