Water-to-Water:
A massive opportunity to do good.
Transforming contaminated water (saltwater, sewage, polluted) into safe, clean water.
Transforming contaminated water (saltwater, sewage, polluted) into safe, clean water.
Other water-purifying technologies pass feedwater through a filter or chemicals are added such as chlorine. Rainmaker’s Water-to-Water technology separates water from all other substances (i.e. waste, chemicals, salt) before it passes through a membrane in vapor form. This system is tremendously more efficient, and is disrupting the water market.
Rainmaker’s Water-to-Water solutions are:
✔ Versatile
✔ Scalable & Cost-effective
✔ Environmentally & Socially Sustainable
✔ Applying Proprietary Technology
✔ Modular and portable
✔ Distributed and decentralized
✔ Wide application use cases
✔ Rapid turnkey deployment
✔ Cost competitive
✔ Solutions easily scalable by adding more units
✔ No large capital required from the customer
✔ Not reliant on local infrastructure
✔ Chemical free
✔ Zero to small carbon footprint
✔ Energy agnostic: wind, solar, grid, diesel or hybrid
✔ Access to clean water, saving lives
✔ Innovative membrane distillation and waste heat recovery system
✔ Algorithms optimize energy use
✔ Networked real time monitoring and control system
✔ Multi-input feed water (saltwater, sewage, polluted) to create potable and medical grade water (Water-to-Water)
✔ Reuse water through a closed-loop system
The leading applications for our Water-to-Water technologies include:
Using a Membrane Distillation process, water is evaporated under low pressure by a heat pump condensation process that recycles the heat through an evaporator. The vapour produced from heating the water passes through the vapour-selective and hydrophobic membranes.
This membrane only allows water vapour to diffuse through, unlike Reverse Osmosis where water containing dissolved salts and other solids pass through the membrane.
The pores in this membrane are also larger than the pores in Reverse Osmosis membranes so there is less pressure and energy required as a
result. The driving force of this technology is the partial pressure difference (temperature difference) between each side of the membrane pores.
They can be efficiently powered by wind, solar, grid, generator, or combinations. Water can now be produced at the point of use, eliminating transportation and distribution costs.
Water-to-Water units are available in three sizes, producing 37,500, 75,000 or 150,000 liters of drinking water per day.
Rainmaker’s Water-to-Water units offer you the most flexibility for power options. Choose from solar, wind, grid, diesel or a combination with zero to small carbon footprint.
Our Water-to-Water system can be powered by a variety of energy sources with varying output capacities. Deployment can be as fast as 90 days after purchase order. Units are operational within 14 days after containers arrive on location.
