LOVE THE FLOW!

We have been using quite a long time now, filtering 8 to 10 Gallons a week for home drinking water. Beats going to the Bottle Water Machines every week and not knowing how the machines are maintained if maintained! Using with the battery pack, which works great! We have also used many times on Camping trips to remote areas. using the SOLAR Panel that is built in to the top of the case. Solar worked just as fast as the battery- I timed both! Takes approximately 4 minutes to fill Gallon jug of water. Have not tried on really dirty water as yet, but nice to know it will filter such if ever needed. Very compact neat little case.easy to take along camping. Prior to purchase the company was very nice about answering all my tons of questions! I do not have any test kits to test water from this, but it tastes great and our tap water is horrible here in SoCal. VERY HAPPY WITH MY FLOW

Solar Disinfection Water Treatment for Drinking Water

Solar water disinfection cleaning: how to disinfect water using solar energy: this article explains using solar heating equipment for correcting unsanitary or unsatisfactory drinking water. Solar water disinfection using solarcatalytic treatment (SODIS) has been under test for some time.

Here we report on recent studies that have improved the efficacy of that approach to using solar power to produce potable water.

We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need.

Solar Water Treatment for Contamination

Solar water purifiers use solar energy to produce potable (drinking) water from available water sources. In a typical solar water purifier design, sunlight is converted either to electrical energy typically to operate distillation equipment, pumps, or evaporators, or sunlight is used directly in the form of heat to operate a distillation process. Water is vaporized (evaporated) from a storage container. Water vapor is condensed on the under-side of a glass or plastic surface where it runs down to a clean-water collection container.

The most rudimentary emergency solar still has been made using clean black plastic trash bags, a hole in the ground, and plants as a moisture source.

Our placeholder photo at page top is a photovoltaic array in use on a restaurant in San Miguel de Allende, Mexico (not powering solar water purification). [Images of solar water disinfection systems sneeded, CONTACT us].

Comparison of Alternative methods for producing potable water using solar power

Photocatalytic enhanced solar disinfection using NF-TiO2 (reported below in this article). Keep in mind that the SODIS approach is aimed at reducing bacterial contamination only.
Solar powered desalinization or demineralization (seeReferences or Citations below). removing salt, e.g. from seawater. By 2014 a San Francisco company, WaterFX had begun demonstrating a solar-powered water-cleaning technology in an effort to address increasing water shortages in the Western U.S Woody (2014).

Output capacity for stationary water purification systems varies by model, ranging from 1 gpm to a system capable of producing more than 8,600 gallons per day. Quoting:

Watch out : reviewing popular solar water purification articles in our research we observe that some writers are confused about the difference between disinfection and purification.

For example, simply using sunlight to heat water in a closed plastic container for some number of hours might reduce the number of bacterial pathogens. those sensitive to high temperatures without having to boil the water. But such water heating may not remove chemical contaminants. though in an open container some volatile chemical components may be driven off or redued.

And without other more effective filtration steps, heating water simply using direct sunlight will not remove fine sediment nor some other pathogens such as giardia cysts, and it may not reliably reduce bacterial contaminants either, depending on the starting level and particular bacteria.

Photocatalytic Enhanced Solar Disinfection of Drinking Water

These Комментарии и мнения владельцев on use of solar powered equipment for water disinfection are based on Final Report: Enhanced Photocatalytic Solar Disinfection of Water as Effective Intervention Against Waterborne Diarrheal Diseases in Developing Countries, National Center for Environmental Research, U.S. Environmental Protection Agency et als.

Quoting from the above report (http://cfpub.epa.gov/ncer_abstracts/index.cfm/fuseaction/display.abstractDetail/abstract/8841/report/F)

Photocatalytic enhanced solar disinfection using NF-TiO2 was responsible for complete inactivation of E. coli in those reactors exposed to both solar and visible light radiation. The presence of NF-TiO2 enhanced the disinfection rate efficiency of E.coli when compared to those experiments where no photocatalyst was used. Practical application of dye solutions as dosimetric indicator appears as very useful for determining the solar radiation dose necessary for waterborne pathogen deactivation.

Similar information from pilot- and benchscale evaluations of APO processes is also included to supplement the commercial-scale data. Performance and cost data is summarized for various APO processes, including vacuum ultraviolet (VUV) photolysis, ultraviolet (UV)/oxidation, photo-Fenton, and dye- or semiconductor-sensitized APO processes. This handbook is intended to assist engineering practitioners in evaluating the applicability of APO processes and in selecting one or more such processes for site-specific evaluation.APO has been shown to be effective in treating contaminated water and air. Regarding contaminated water treatment, UV/oxidation has been evaluated for the most contaminants, while VUV photolysis has been evaluated for the fewest. Regarding contaminated air treatment, the sensitized APO processes have been evaluated for the most contaminants, while VUV photolysis has been evaluated for the fewest.APO processes for treating contaminated solids generally involve treatment of contaminated slurry or leachate generated using an extraction process such as soil washing. APO has been shown to be effective in treating contaminated solids, primarily at the bench-scale level.

This will be deployed in the U.S.A., as well as developing nations in order to increase general health, increase stability of community reliance on salt and chemical contaminated ground water sources.Summary/Accomplishments (Outputs/Outcomes): Over the last year, we produced a hand-made SEA unit to test the feasibility of our initial research. Initial results encouraged us to produce a unit that would closely resemble a deployable, mass-produced SEA unit. This required full-sized industrial plastic molds and thermoformed plastic SEA units. After about a year of working to achieve necessary funding to acquire evaluation samples of production SEA Panels, we began in-lab and field-testing of the units. Significant further research and development is needed to increase condensation-gathering efficiency of the units and test the units in real-world applications. Specifically, we hope to gather efficiency data to determine cost-benefit of using an active barrier-cooling system on the condensation barrier. We also hope to optimize geometry of the condensation barrier to encourage water-gathering efficiency.Conclusions: In conclusion, we have produced a fully functional system, which can provide potable water from any contaminated water source. Unlike methods that use molecular osmotic screens, the SEA requires minimal maintenance and cannot be rendered useless by dissolved chemicals like chlorine. Most important, the SEA is a good example of sustainable design in that it successfully captured crystalline salt rather than emitting toxic salt brine and the units double as rain-capture devices which may help to eliminate malarial vector breeding on flat roofs.Our proposed Phase II objectives and strategies are to gather highly critical data from field tests and more controlled tests to determine optimal SEA design to maximize waterproducing efficiency while hopefully lowering manufacturing complexity and therefore cost per panel. We also need to determine if theoretical advantages provide a high enough cost-benefit ratio to justify increased manufacturing cost. We need to determine best use and types of biocides and /or ultraviolet treatment to control algae and pathogens. We need to determine optimum mixing ratios with untreated water for ground water demineralization. We also need agricultural field-testing to determine best use integration of the SEA system with low-pressure drip-irrigation systems. Finally, we need to test SEA in a variety of configurations and global locations to determine optimum installed best practice for untrained and minimally trained users.

SOLAR MULTI-USE WATER SYSTEM (SOLARMUS)

Pronounced ‘solar moose’, this simple system is known for its solar-powered water pumping abilities. The SolarMUS uses energy from the sun to pump water from a distant source to storage tanks strategically placed above a community. These tanks store a large amount of water, usually up to three days’ worth. This ensures a reliable supply of water year-round. Once in the storage tanks, the system cleverly lets gravity do the rest, piping water back down hill to tap stands outside each home and within easy reach of fields, and to schools, clinics and other institutions in the community. This is a big reason it is so efficient – only half of the power normally needed to distribute the water is used. With the simple turn of a spout below, water is distributed to households, farms, and businesses on-demand. It is called a multi-use system (MUS) for this very reason. The water can be used for many purposes such as drinking, cooking, sanitation, irrigation, and more.

Where is the SolarMUS appropriate?

The SolarMUS is best used in hilly regions where communities live above their nearest water source. They can also be useful for communities who live in flat areas but are simply a long distance away from a dependable supply of water. Because it relies on solar energy, this system is also best for regions that experience many days of sunshine each year.

Unlike our Hydram systems (which require a high volume of water), this system can be used in areas where the water source is low in quantity, such as a naturally occurring spring. This unique feature, paired with system lifespans of 20 years, make this technology a highly versatile and practical solution.

At present, SolarMUS systems are primarily used within our Nepal programme where communities living in the foothills of the Himalayas have serious restrictions on the water they can access. We work with communities to install the SolarMUS systems in order to improve access to water for household as well as agricultural use. We support communities with WASH training, agricultural training as well as the tools and skills that they need to maintain the system going forward.

Fun fact, these systems have the potential to lift water over 200 vertical metres – this is extremely helpful when working in mountainous terrain like Nepal! Speaking of, did we mention that we have already delivered 29 SolarMUS systems in Nepal? Well, we have, and these systems are currently lifting an incredible 436,843 litres of water per day (enough for 7,000 showers) to a total of 8,475 people.

How does the SolarMUS really work?

A solar photovoltaic (PV) array generates electricity as Direct Current (DC) from the sun’s light. This electricity drives a motor in a connected pump and brings the pump into operation. The pump lifts water, from the source(s), up to a storage tank or reservoir located above the community. A gravity fed system then distributes the water down to individual tap stands, outside homes and within easy reach of fields.

– A collection tank is constructed near the water sources to collect the water from different sources.

– The pump is submerged under the water in the collection tank (if the pump is a submersible type) or near the collection tank (if it is a surface mounted type). Solar panels are erected close to the collection chamber, ensuring that the solar array gets that maximum number of hours of sunshine as possible. The solar PV array generates the electricity as DC.

– The electricity generated from the solar PV array passes through the cable to drive the motor, and the motor operates the pump. If an Alternative Current (AC) pump is used, an inverter is required to convert the DC to AC.

– The pump draws water from the collection tank and delivers it to the storage tank through a delivery pipe. The storage tank is constructed at the top of the village and the size of the tank is designed to allow at least 3 days of autonomy (i.e. it will be made large enough to hold 3 day’s worth of water). This means that even if there are 3 consecutive days of cloudy weather when the pump is not in operation, there is still sufficient water for distribution.

– A distribution pipe carries the water from the storage tank to a series of taps and outlets at various locations in the community.

– Water can be released on-demand by community members.

Should you have questions about SolarMUS our highly experienced field team would be happy to answer them. Contact us at getintouch@renewable-world.org.

We believe SolarMUS technology is a promising renewable energy solution. However, it wouldn’t be sustainable or profitable without the direct involvement, training, and cooperation of communities. This is why we put communities at the centre of our work – working with them from day one to create a long-term vision and management plan.

Solar-powered water desalination tech for off-grid applications

Berlin-based Boreal Light has developed water desalination tech powered by PV for off-grid applications. The solution uses 460 W solar panels from Chinese module manufacturer DAH Solar and produces clean water from direct seawater at a cost of €0.50 (

Boreal Light, a German technology company, has developed a PV-powered water desalination machine for off-grid applications.

The Winture Planet Cube machines have capacities from 1,000 liters per hour to 50,000 liters per hour. The size of the solar array needed to power these machines is a function of three factors: their capacity, the salinity of the water, and the depth of the borehole which water is extracted from. The technology uses seawater, wastewater, brackish water, or surface area as inputs.

“On average, a machine of 2,000 liters per hour needs a PV array with an installed capacity of 11 kW, for most projects we developed in Sub-Saharan Africa,” Hamed Beheshti, CEO of Boreal Light told pv magazine. Other projects include a 15,000 liter per hour machine in Iraq using a 90 kW PV system.

Boreal Light oversizes the solar arrays to sidestep the need for using batteries.

“We are extremely against using batteries because it brings a lot of extra costs, transportation, and maintenance. Instead of storing electricity from the solar panels, we produce more water and store it – it is way cheaper,” said Beheshti. “The machine in the Iraq project, for example, needs a maximum of 49 kW of electricity.”

The excess water is usually used for fish farming, irrigation, and sanitation. The company also uses the electricity excess for charging electrical cargo bikes used for distributing water, and for charging battery banks of nearby schools.
