100% Water recycling to world standards drinking quality specification
Background: Applications and Treatment
The Re:Water recycling process is a natural reoccurring process, with advancements in treatment technologies; water can be recycled more efficiently to meet our needs. Re:Water can be accomplished by several different methods and depending on applications of the planned reuse will determine the amount of filtration and handling of supply for potability. Re:Water is a term describing the reclamation, treatment and recycling of wastewater or storm water collected from homes, commercial buildings and industrial facilities. Water polishing is the term used to complete the water treatment process to potable water for consumption. Drinking water is only one (1%) percent of the water consumed. As such tremendous opportunity lies in Re:Water for a variety of other non-potable purposes.
Re:Water is used in three main ways: (1) non-potable (non drinking) which involves taking treated wastewater to use for agriculture and landscaping irrigation, industrial use, toilet flushing and fire protection; (2) Re:Water is already a widely accepted practice that will continue to grow, and indirect potable reuse is becoming a favored method over discharging water back to the source; (3) Re:Water for potable use and drinking water.
The Process of Re:Water for Drinking Water
The international standard for recycling water into potable water is a three-stage process that combines physical, biological and chemical means.
The First stage, known as primary treatment, removes large physical debris, grit and sediment.
The Second stage of treatment uses biological processes to remove remaining contaminants. Populations of bacterial microorganism’s breakdown organic material within the water, consuming it like food.
The Third stage of the process, known as advanced treatment, prepares the water for reintroduction into fresh water supplies. Sand filters and disinfectants are used to remove any remaining bio-organism and chlorine from the water, before releasing it back into water reservoirs as ‘effluent’.
Water ‘Polishing’ For the Home and Office
The First stage is accomplished through filtration with a micro filtration to remove particles from the pantry area sink.
The Second stage is Charcoal filtration and with filter media before reverse osmosis. Reverse osmosis sees the water passed through a semi-permeable membrane to remove microscopic bacteria and debris.
The Third stage water is then purified with ultraviolet disinfection and micro filter with media, making far more pure drinking water.
Embracing new technologies to sustain water demands with Re:Water. is what precisely the world will benefit from.

Re:Water™ recycle used water and generate new water from natural sources from rain, air, and water storms. A full depiction follows:
The Re:Water™ Wastewater treatment Solution
The biggest problem of many developing cities is the treatment of sewage. Excess sewage is allowed to drain into landfills and result in pollution of aquifers and underground water. Untreated sewage is also the cause of unwanted odors and waste that cannot be disposed of.
The Re:Water Wastewater Sewage Treatment system uses a Closed Loop Reactor (CLR) Process to effectively treat sewage and recycle the water for reuse in agriculture and other purposes.
Diagram 3: CLR Process – Aerial View
The CLR process is a modified version of the extended aeration, complete mix process, providing the elements for biological nutrient removal. This process produces removal efficiencies that meet and exceed the efficiency of advanced tertiary treatment process. The CLR process is a centralized process that receives black water from major pipes and plumbing sources or from a wastewater collection cistern. Heavy grit is allowed to settle before being removed in the Grist Classifiers. The water is cleaned using aeration and further filtered in the Spiraflo Clarifiers before being discharged into irrigation fields, pumped into buildings, or stored in water tanks.
Diagram 5: Spiraflo Clarifiers
The Spiraflo Clarifiers are needed in two stages, primary clarification and the final clarification process. The final clarifier is the “heart” of any biological process. The Spiraflo Clarifier is proven to be from 2 to 4 times more hydraulically efficient than a center-feed clarifier. This part of the process is vital is ensuring that all sludge is removed from the water prior to aeration. It also has a surface skimmer that collects scum, grease or anything floating at the surface of the water.
A typical CLR process produces two final products, water and sludge. The water can be churned back into the Triple “R” System for further recycling and possibly into drinking water. The sludge can be reproduced into pellets that are used as fertilizer in agriculture or dried sludge is usually disposed of in landfills. If the sludge is not needed for fertilizer, there is a second option for the CLR process that produces zero sludge. This process of sludge removal is currently used in military bases and offshore oil rigs.
The CLR Process can produce up to 3,700 tons of water per day and can be customized to produce up to 37,000 tons of water per day.

RE:Water™ Water Collection System
The Rain Water Catchment System is an automated water collection system that collects runoff rain water for reuse as potable water, or for agriculture purposes. A version of this system is part of the patent pending Triple “R System as mentioned in point 3.1.
The rain water basin uses an infrared light sensor to detect rainfall and automatically opens a reverse umbrella top as a catch for rain water. The umbrella top is automatically closed by the same infrared sensor to prevent catchment of debris, and fallen particles. The collected rain water is sent to an ozone generator for purification.
The entire Rain Water Catchment System is powered entirely by wind (with an option to use solar). Methane gas produced by the waste basin is also used to power electric generators that can provide energy source to the system and the community as well.
Re:Water™ Cultivation System
The Cultivation System taps existing water from nearby rivers and lakes by pumping water through vertical turbine pumps into a reverse osmosis (RO) membrane system for preliminary cleaning. The cleaned water is then channeled into a modified version of the Triple “R” System and treated with UV before entering a double media filter.
The water is injected with Kelzyme, a natural soil conditioner and fertilizer. Kelzyme is assimilated from plants and is proven to repress harmful bacteria and fungi in the soil, as well as act as stimuli for growth of helpful bacteria in the soil that release, fix, or create nutrients for crops. The agriculture water is distributed via a pump booster system, through pipelines, and into farms.
