Florida Soft WaterWater is generally classified into two groups: Surface Water and Ground Water. Surface water is just what the name implies; it is water found in a river, lake or other surface impoundment. This water is usually not very high in mineral content, and many times is called “soft water” even though it usually is not. Surface water is exposed to many different contaminants, such as animal wastes, pesticides, insecticides, industrial wastes, algae and many other organic materials. Even surface water found in a pristine mountain stream possibly contains Giardia or Coliform Bacteria from the feces of wild animals, and should be boiled or disinfected by some means prior to drinking.
Ground Water is that which is trapped beneath the ground. Rain that soaks into the ground, rivers that disappear beneath the earth, melting snow are but a few of the sources that recharge the supply of underground water. Because of the many sources of recharge, ground water may contain any or all of the contaminants found in surface water as well as the dissolved minerals it picks up during it’s long stay underground. Waters that contains dissolved minerals, such as calcium and magnesium above certain levels are considered “hard water” Because water is considered a “solvent”, ie, over time it can break down the ionic bonds that hold most substances together, it tends to dissolve and ‘gather up’ small amounts of whatever it comes in contact with. For instance, in areas of the world where rock such as limestone, gypsum, fluorspar, magnetite, pyrite and magnesite are common, well water is usually very high in calcium content, and therefore considered “hard”.
Due to the different characteristics of these two types of water, it is important that you know the source of your water — Surface or Ground. Of the 326 million cubic miles of water on earth, only about 3% of it is fresh water; and 3/4 of that is frozen. Only 1/2 of 1% of all water is underground; about 1/50th of 1% of all water is found in lakes and streams. The average human is about 70% water. You can only survive 5 or less days without water.
Why Should Hard Water Concern Me?
Florida Soft WaterFor many uses, it would not matter. For instance, to put out fires, water your lawn, wash the mud off the streets or float your boat, water would have to be pretty hard to cause a problem. But for bathing, washing dishes and clothes, shaving, washing your car and many other uses of water, hard water is not as efficient or convenient as “soft water.” For instance:
~ You use only 1/2 as much soap cleaning with soft water.
~ Because hard water and soap combine to form “soap scum” that can’t be rinsed off, forming a ‘bathtub ring’ on all surfaces and drys leaving unsightly spots on your dishes.
~ When hard water is heated, the hardness minerals are re-crystallized to form hardness scale. This scale can plug your pipes and hot water heater, causing premature failure, necessitating costly replacement.
~ The soap scum remains on your skin even after rinsing, clogging the pores of your skin and coating every hair on your body. This crud can serve as a home for bacteria, causing diaper rash, minor skin irritation and skin that continually itches.
~ For many industrial uses, the hardness minerals interfere with the process, causing inferior product.
My Water is Hard; Now What?
Florida Soft WaterIf your water tests over 3 GPG hard, you should mechanically soften it. Softening water that is less than 3 GPG, while it makes your shaving and bathing more comfortable, is considered a luxury due to the fact that the cost is more than your savings. Over 3 GPG, you will save enough to pay for the cost and maintenance of a water conditioner.
As of this writing, the most economical way for you to soften your household water is with an ion exchange water softener. This unit uses sodium chloride (salt) to recharge man made plastic like beads that exchange hardness minerals for sodium. As the hard water passes through and around the plastic like beads, the hardness minerals (ions) attach themselves to the bead, dislodging the sodium ions. This process is called “ion exchange”. When the plastic bead, called Resin, has no sodium ions left, it is exhausted, and can soften no more water. The resin is recharged by flushing with salt water. The sodium ions force the hardness ions off the resin beads; then the excess sodium is rinsed away, and the resin is ready to start the process all over again. This cycle can be repeated many, many time before the resin loses it’s ability to react to these forces.
What Should I look for in a Water Conditioner?
Florida Soft WaterMake sure the unit has enough resin to treat all the water you and your family will use. As of this writing, the average usage per day, per person (including children), for inside the house is 87 gallons. You should also be shown two or three ways to initiate recharging the unit.The oldest way is by a timeclock, ie, your water usage is calculated and the frequency of recharging programmed into the timer. On the appointed day, at the appointed hour, the unit recharges. If all went as calculated, ok. If you were gone — too bad — you just wasted salt and water. If you had extra company — too bad — you ran out of soft water. You must pick a unit that will treat one days supply of water and still have about 40% of the resin in the recharged state. This will provide you with the most efficiency for salt and regeneration water.A second way to initiate recharge is by using a meter. These units have a meter installed in the water line and simply measure how many gallons of water you actually used. The unit is set according to your water hardness, and will recharge when the gallons used approach exhaustion of the resin bed, saving you a high percentage of your recharge salt and water.Many variations of these methods are on the market. Some use computers to calculate in advance, when to recharge the unit; some have two resin beds (tanks), and switch back and forth between the two, keeping you in soft water all the time, at the highest efficiency. These systems are most effective in high-hardness waters, ie, over 10-12 GPG, and over 4 people in the family. Low hardness water and smaller families do not require the extra expense of these options.
I Have a Water Conditioner, Now my Water Feels “Slimy”
Florida Soft WaterWhen the hardness minerals are removed, soap no longer forms a soap curd, or “bathtub ring” on your skin, plugging your pores, clinging to every strand of hair. You are now truly clean. That slick, slimy feeling you feel is your natural body oils — without the soap scum. The old saying that you get “squeaky clean” is a myth; that feeling was caused by the soap scum on your skin. By the way, that soap scum provided an excellent place for bacteria to hide and grow, causing numerous minor skin ailments.
My Water Stinks! What can I Do?
Florida Soft WaterFirst, you must learn a little about your nose: Once you smell some things, your sense of smell is dulled for a short while, and you can’t make accurate judgments of smell. For instance, if I blindfold you, let you smell gasoline, hand you a piece of onion to eat and tell you it is an apple, you can’t tell it’s not because your nose isn’t working properly!! (Your sense of taste isn’t working either — smell and taste are closely related and affect each other!)
So, to correctly analyze your problem, you need to become a detective. The best time to locate the smell is after you have been away from home for a few hours — this allows your nose to become sensitive to “that smell” again. With your ‘sensitized’ nose, go to an outside spigot — one that the raw, untreated water flows from. Turn it on, let it run a few minutes, then smell it. If it smells — we found it. If not, we must look further. (Many, many smells are not in the raw water at all, they are introduced into the water inside the house.) Go to a cold, treated water spigot inside the house, turn it on and let it run a minute; then smell. If this water smells, and the outside, untreated water didn’t — you must have a device (cartridge filter, water softener, etc.) in the water line that needs to be cleaned and sanitized.
If it is a cartridge, or ‘string’ filter, replace the element and sanitize the housing. If you have a water conditioner call Florida Soft Water. If you rent the unit, just call! You can sanitize the unit by pouring Citric Acid or Chlorine Bleach in the brine well of the salt tank, and placing the unit into regeneration.
If the cold, treated water inside didn’t smell, turn on the hot water and let it run a few minutes — does it smell? If it does, chances are you have a sacrificial anode inside your hot water heater that is “coming apart at the seams” and throwing off a “rotten egg” odor. This obnoxious smell will drive you right out of your shower! The only solution is to remove the anode from the heater, voiding your warranty, or replace it with a new one made with aluminum alloy. This anode is placed in a (glass lined) hot water heater to seal up any cracks in the glass lining and prevent corrosion of the heater tank. You will find the anode on the top of the heater; remove the tin cover and insulation — look for what looks like a pipe plug — about 3/4 inch in size with a 1 1/16″fitting. Turn off the heat source and the water; have someone hold the tank to prevent it from turning, and unscrew the “plug”. You will find that the ‘plug’ has a 30 – 40 ” long pipe (or what’s left of one) attached to it. Hopefully, most of the rod is still attached — just corroded. If so, replace the plug with a real pipe plug and throw the anode away. If part of the rod has corroded off, and fallen into the heater, you may have to try to fish it out. Either way, before you plug the hole, pour about 2 pints of chlorine bleach into the heater first. This will kill the smell left in the heater. If, after a week or so, the smell returns, you must fish out the rod that is in the bottom of the tank. Good Luck!
OK, It’s my Raw Water That Smells — Now What?
Florida Soft WaterFirst, you must determine what is causing the smell, and how strong it is.
Minor, musty smell
If it is a minor, or low-level smell, you MIGHT be able to solve it with a small, point-of-use carbon filter. You can place these types of filters on the water line going to the cold water where you draw you drinking water. Or, you might solve it with a whole-house filter on your incoming water line to filter all of the water inside your home.
Because carbon removes smells by ADsorbtion, ie, the smell “sticks” or “adheres” to the carbon particles, you must be careful not to exceed the manufactures recommended flow — some filters even have a flow restriction built in them. If you run water through them too fast, you will not remove the smells. Whenever you place a carbon filter in your water line, you must be sure to replace the element and sanitize the housing on a regular basis. Carbon filters remove organics from water, and the bacteria found in water like to eat organics — the carbon filter is a nice, dark place, just full of food for them to grow and reproduce in. Regular and routine replacement will help prevent any buildup of bacteria in the cartridge.
What if I experience a strong, rotten-egg smell?
Florida Soft WaterStrong, rotten-egg odors in the raw water is usually the result of the decomposition of decaying underground organic deposits. As water is drawn to the surface, hydrogen sulfide gas can be released to the atmosphere. In strong concentrations, this gas is flammable and poisonous. It rapidly tarnishes silver, turning it black. It is toxic to aquarium fish in sufficient quantities. As little as 0.5 ppm hydrogen sulfide can be tasted in your drinking water.
How do I remove hydroge sulfide smell?
Florida Soft WaterInstallation of a whole house filter loaded with a media that is specific for hydrogen sulfide removal is successful many times. These types of filters must be recharged with chlorine or potassium permanganate. The removal capacities of these types of filters are usually fairly low, and must be sized to contain enough media to prevent premature exhaustion, and subsequent passage of the smell to service. It is also typical that the amount of hydrogen sulfide can fluctuate rapidly, causing great difficulty in sizing the unit. In addition, potassium permanganate is extremely “messy”, and will leave stains that are very difficult to remove.
I have Red Stains in my Sinks and Other Fixtures — Help!
Florida Soft WaterRed stains are normally caused by iron in the water. You must test to determine the amount and the type of iron you have. Some types are: oxidized, soluble, colloidal, bacteria or organic-bound. All are a problem! It only takes 0.3 ppm to stain clothes, fixtures, etc.
This type of iron is usually found in a surface water supply. This is water that contains red particles when first drawn from the tap. The easiest way to remove this type of iron is by a fine mechanical filter. A cartridge type filter is usually not a good solution, due to the rapid plugging of the element. Another method or removal is by feeding a chemical into the water to cause the little particles of iron to clump together, and then fall to the bottom of a holding tank, where they can be flushed away.
Soluable iron is called “clear water” iron. After being drawn form the well and contacting the air, the iron oxidizes, or “rusts”, forming reddish brown particles in the water. Depending on the amount of iron in the water, you may solve this problem with a water conditioner, or a combination of softener and filter. You may use an iron filter that recharges with chlorine or potassium permanganate, or feed chemicals to oxidize the iron and then filter it with a mechanical filter. You can sometimes hide the effects of soluble iron by adding chemicals that, in effect, coat the iron in the water and prevent it from reaching oxygen and oxidizing.
Colloidal iron is very small particles of oxidized iron suspended in the water. They are usually bound together with other substances. They resist agglomeration, ie, the combining together of like substances forming larger, heavier, more filterable ones, due to the static electrical charge they carry. This iron looks more like a color than particles when held up in a clear glass, as they are so small. Treatment is usually one of two: Feed chlorine to oxidize the organic away from the iron, thus allowing agglomeration to occur, or, feeding polymers that attract the static charge on the particles, forming larger clumps of matter that is filterable.
Iron bacteria are living organisms that feed on the iron found in the water, pipes, fittings, etc. They build slime all along the water flow path. Occasionally, the slimy growths break free, causing extremely discolored water. If a large slug breaks loose, it can pass through to the point of use, plugging fixtures. These types of bacteria are becoming more common throughout the United States. If you suspect bacteria iron, look for a reddish or green slime buildup in your toilet flush tank. This type of iron problem is very hard to eliminate. You must kill the bacteria, usually by chlorination. You must use high amounts of chlorine throughout your plumbing system to kill all organisms. You may find it necessary to feed chlorine continuously to prevent regrowth. A filter alone will not solve this problem.
When iron combines with tannins and other organics, complexes are formed that cannot be removed by ion exchange or oxidizing filters. This iron may be mistaken for colloidal iron. Test for tannins; if they are present, it is most likely combined with the iron. Low level amounts of this pest can be removed by use of a carbon filter, which absorbs the complex. You must replace the carbon bed when it becomes saturated. Higher amounts require feeding chlorine to oxidize the organics to break apart from the iron and cause both to precipitate into a filterable particle.
