Solar Desalinators, Water Purifiers and Stills Do It Yourself DIY

Equipment required:

10,000 gpd vapor compressor

1000 gallon recycle tank
500 gallon brine tank

Useful information

1 cubic foot water = 7.48 gallons

1 gallon water = 8.34 pounds

1 cubic foot of water weighs approximately 62pounds

1 cubic foot of concentrated solids to 5% moisture weighs approximately 100 pounds

Sand w/ Gravel, wet = 125 pounds per cubic foot

Sand w/ Gravel, dry = 108 pounds per cubic foot


 

10,000 gpd at 1000ppm = 8,340 pounds solids per 1,000,000,000 gallons (83.4 pounds of solids per 10,000 gallons).


A 10,000 gpd vapor compressor generates 9,000 gallons of distilled water and 1,000 gallons of reject brine water at 10,000 ppm if the influent is 1,000 ppm.

 

This 1,000 gallons of 10,000 ppm reject water must be compressed , yielding 900 gallons of distilled water and 100 gallons of reject brine at 100,000 ppm (84 pounds).

 

900 gallons of 10,000 ppm reject brine should be added to the 100 gallons of 100,000 ppm reject brine water in the 1,000 gallon tank, producing 1000 gallons of reject brine water at 15,000 ppm (approximately 150 pounds solids).

 

The 1000 gallons of reject brine water at 15,000 ppm will be compressed to 100 gallons of 150,000 ppm reject brine.

 

900 gallons of 10,000 ppm reject brine should again be added to the 100 gallons of 150,000 ppm reject brine (approximately 225 pounds solids) This batch should be compressed and stored in the 500 gallon brine tank for solids recovery.

 

The final reject brine is at 210 degrees Fahrenheit and will cause rapid evaporation. Supersaturation may be achieved with no additional heat.

Sundragon Salt Factories 100% Green No Salt Brine.

Salinity management is a zero brine discharge system. Desalination liquid concentrate disposal is the challenge.

Anyone can desalinate seawater or brackish ground water, liquid brine concentrate disposal is the issue.

Desalinators make salt free water with a brine reject. The salt doesn't go away.

SunDragon collects all the salt and impurities from seawater or brackish ground water producing dried salt and distilled water.

No need to pretreat water

Our processes collect all salts and solids from water.

We distill 100% of the feed water and collect 100% of the dissolved solids in the feed water.

The highly-corrosive properties of the effluent stream from RO and Vapor Compression desalinators is not a problem for the SunDragon Salt Maker systems.

The protection of the environment is a critical consideration in the design functionality of the SunDragon.

Water is increasingly coming into investors sights as despite its scarcity the potential for growth is vast. The steady increase in water scarcity, the continuous depreciation of our water infrastructure, and the on-going degradation of our water environment the crisis is here.

There are 6 solar zones if you are in one of the lower solar zones forget solar stills or any solar evaporators. Southern California, Arizona, New Mexico and West Texas are best for solar water purifiers. 100+  Annual Sunny Days Cities At 100 days plus solar may work for you however if you are going to use passive solar it is cheaper to buy the water than buy a solar still.

How Homeowners on Well Water Use Calcite (Crushed Marble) to Neutralize Corrosive Well Water This will work with distilled water and makes the water taste better.

Crushed marble, also known generically as calcite, is a naturally occurring calcium carbonate media that is crushed and screened. It can be used inexpensively to neutralize acidic or low pH waters to a neutral, less corrosive condition. View Article

Both designs rely on heat from the sun to heat a mass of water. The heated water releases water vapor, which condensates on the glass or plastic cover and runs into a trough or collection pan. This type of solar still makes pure water and is not vary expensive.

The Problem:

No manufacture of solar evaporators that I can find has NSF certifications, tested for purity and conformity to existing US (EPA) standards for drinking water quality. These certifications are expensive, and the current design and operational methods for solar evaporators has low production as to quantities of distilled water produced under any sun conditions. This low production of the box evaporator has kept this technology from becoming popular.

A solution:

For home use, or in remote areas to increase water production from your box evaporator, use hose water heating to preheat the water to be evaporated: feed water as the water is known. Feed water heats in a hose much faster than the mass of water in the evaporator. Feed water can be recirculated through the evaporator and the agitation of the evaporator water increases the release of water vapor.

A 50 ft. hose holds about a gallon of water. Fortunately hose is inexpensive and readily available.

How Hot, How Clear?

Solar Survey Water Still Use

Temperatures above 85 degrees F and clear sunny skies are the lower temperatures that this type of system work well in. Black hose is best to preheat feed water although in extreme circumstances; any garden hose or PVC pipe will work. You should make a solar box for your hose if possible; this will increase the hose heat. The more hose the better; the volume of hottest water generates the greatest amount of water vapor and purified water.

 

For there to be noticeable improvement in output production of distilled water from a box evaporator a minimum feed water temperature of 150 degrees F is required. With a constant 200 degrees F moving water you will evaporate at least 70% of your evaporative water. Our lab test of 203 - 206 degree water constantly moving actually evaporated 82% of the evaporator water. Ideally 180-190 degrees is preferable for the best quality of water.

Building a box evaporator is easy; it can be made from a variety of materials. Plywood and plastic food grade polyethylene sheeting are readily available and inexpensive. Polyethylene is polyethylene, plastic is food grade polyethylene is polyethylene. Glass may be used if you are making a flat cover box evaporator. Curved or dome shaped covers offer more surface for condensation a advantage with the preheated method.

Volatile Organic Compounds (VOCs)

Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects.Volatile organic compounds may have a variety of harmful health effects. At high levels of exposure, many VOCs can cause central nervous system depression (drowsiness, stupor). All can be irritating upon contact with the skin, or to the mucous membranes if inhaled.

The most effective method for preventing VOC contamination is to ensure that these compounds are not used or disposed of near wells or surface water supplies. Protecting your water source is the most effective method to eliminate exposure to these chemicals. Be sure that your well is constructed properly and is protected to prevent surface water from moving down the well casing into your drinking water supply.

Vented gas tanks: a tank that preheated feed water is sprayed into and is vented to remove odors and gases from water. This should be done prior to evaporation.

Carbon filtration can be used too remove VOC's; water should be filtered after evaporation.

According to the Internet, this Chinese farmer is getting hot shower water from this roof of beer bottles and plastic tubing. This version of the story was seen on Ananova (sent in by reader Arnaud Betremieux). The account says: "I invented this for my mother. I wanted her to shower comfortably," says Ma Yanjun, of Qiqiao village, Shaanxi province. Ma's invention features 66 beer bottles attached to a board. The bottles are connected to each other [with plastic tubing] so that water flows through them. Sunlight heats the water as is passes slowly through the bottles before flowing into the bathroom as hot water, reports China Economy Network. Ma says it provides enough hot water for all three members of his family to have a shower every day.And more than 10 families in the village have already followed suit and installed their own versions of Ma's invention."
