Solar Waste Water Evaporator System

The Waste water will be pumped on a Metal Open tray (painted with absorber paint) through a simple pump and from there it will be falling on the Receiver by gravity. The receivers will be heated by concentrating solar energy. The temperatures on the Receivers will be more than 1,000° C. The falling water on the receivers will start evaporating and the rest of the water which is not evaporated will be heated up. The heated water will fall again in the nearby Solar Pond through a sprinkler system and the cycle will be repeated continuously. 

Welcome to our innovative solution for sustainable water evaporation using solar energy. Our system utilizes a combination of simple yet efficient mechanisms to harness the power of the sun for water treatment. By employing metal open trays coated with absorber paint and concentrating solar energy, we ensure effective evaporation of wastewater while minimizing energy consumption.

How It Works:

  1. Wastewater Pumping: The wastewater is pumped onto metal open trays coated with absorber paint using a simple pump.
  2. Solar Heating: The trays are exposed to concentrated solar energy, raising the temperature on the receivers to over 1,000°C. As the water falls onto these heated receivers, it begins to evaporate, leaving behind impurities.
  3. Evaporation and Heating: The falling water undergoes evaporation, while the remaining water is further heated. This dual process ensures efficient treatment of wastewater.
  4. Water Recycling:  The evaporated water vapor is collected and condensed, leaving behind purified water. The heated water that doesn’t evaporate completely is directed back into a nearby solar pond via a sprinkler system, ready to be cycled through the process again.


  • Energy Efficiency:  By harnessing solar energy for heating, our system significantly reduces the need for external energy sources, making it environmentally friendly and cost-effective.
  • Water Conservation:  Through evaporation and condensation, we efficiently treat wastewater, providing a sustainable solution for water recycling and conservation.
  • Low Maintenance:  With its simple design and reliance on natural processes, our system requires minimal maintenance, ensuring long-term reliability.


Our sustainable water evaporation system offers a scalable and eco-friendly solution for wastewater treatment. By harnessing the power of the sun, we aim to contribute to a cleaner environment and a more sustainable future. Join us in embracing innovation for a greener tomorrow.
