We believe,
WATER has a very limited capacity to hold Oxygen when compared to SOIL and that's why centuries back Life moved out of Water to SOIL. We use soil as the medium to hold the required micro & macro life forms that are crucial for cleanup of wastewater. We bioengineer the soil and call this as "BioActive Soil". Our bioengineering of this BioActive soil layer brings about the required bioconversion to rejuvenate the waste water, hence the name rejuWATER™.

BioActive soil layer is continuously fed with Oxygen supply and we do not use a blower to do this! We use Canna Indica, a wild plant found in the marshy land surrounding water bodies. The roots of Canna Indica liberate Oxygen. So, when we plant this in to the BioActive Soil layer, all along the roots, huge colonies of aerobic microbes develop. Also, the porosity of soil is able to distribute the liberated Oxygen through out the BioActive Soil layer.

When wastewater is trickled through this BioActive soil, our waste in the water which is food for microbes gets eaten up quickly by the microbes. There is always a huge colony of microbes ready to feed on the waste in the wastewater. Microbes, break up the complex molecules in to simpler ones that get consumed by the roots of Canna Indica. Hence whatever is excreted by the microbes is taken up by the plants, which means ZERO SLUDGE!

Canna Indica grows very fast in our sewage wastewater treatment and needs to be pruned quite frequently. Also to maintain enough growth space some plants need to be uprooted once in 2-3 weeks. This is all the maintenance required to run our STP, efficiently.

Challenges with Electromechanical STP's
Three important facts where the conventional sewage treatment plants using electromechanical design suffer:

1. requires 24x7 Power Suppy:
Conventional Electromechanical STP needs DG backup power to assure continuous supply of Oxygen to Microbes. Power failure cuts the O2 supply & microbes begin to die destabilizing whole system.
2. trying to split Oxygen from air:
The whole idea of pumping air in sewage treatment process, assuming that Oxygen molecule will break up from air and get dissolved in water is more a wishful thinking, it might be happening, but the diffusion rate is hardly 10%. Also, what do you do with the 79% Nitrogen that is left behind after disassociation of the Oxygen molecule. On one hand we face a challenge of Nitrogen & Phosphorous removal during treatment of sewage, on the other hand we are pumping Nitrogen back in to the same system!

3. Indian warm climate supports Anaerobic processes:
Wastewater treatment in india, will remain to be a challenge, because wastewater treatment plant manufacturers continue to support the aerobic wastewater treatment methods where as Indian climate supports Anaerobic Digestion (AD) technologies.
Our Solution
Aerobic technologies work well in cold climates. Warm climate supports effortless growth of Anaerobic bacteria.

Aerobic requires electricity Anaerobic doesn't. But, Anaerobic is not a preferred system, due to assumption that it would smell bad everywhere.

Anaerobic produces Hydrogen Sulphide, Ammonia & Methane that are foul smelling, but to handle these gases, without spreading the foul odour around, is a case of engineering.
