Introduction

  • Most of the Indian villages and urban sector have hard water supply in community pipelines

​

  • Hard water contains high concentrations of calcium and magnesium, which lead to limescale buildup.

​

  • Over time, lime scale deposits clog pipes, reduce appliance efficiency, and decrease water flow.

​

  • Scaling in community water pipelines introduces multiple issues

​

      • Water quality
      • Water flow rate
      • Pipe quality
      • Maintenance expense

Proposed Idea

Scale Fighter Embedded Unit

Generated signal produces a wave current that sweep all frequency response

Generated signal causes the ions to participate and collide with each other to the point where calcium crystal grows until they become so large that there are no surface charge left to stick to th pipe walls or other surface

Generated current introduces a temporary magnetic field which suppress the charge of ions and also the property to precipitate

Induction coil wrapped around pipe on incoming water supply

Delivers multiple freq.

Incoming water containing CaCO3

Unique and complex modulating frequency waveform hits the resonant frequency of CaCO3 molecule causing them to lose their adhesive property

Power Supply and battery management unit

Microcontroller unit to generate specific programmable frequency chunk

Amplification and waveform shape tuning to generate specific resonant frequency

Testing load (coil to generate magnetic field)
