Now, 1800 lb H2O/(1,000,000 mol N.G./379 SCF/mol) =Ĭonverting PPMv moisture content to LBS-H2O/MMSCF in Natural GasĪssume you have 150 ppmv of moisture in natural gas (CH4) This means you have 100 moles of water per 1,000,000 moles of N.G.ġ00 mol H2O/1,000,000 mol CH4 * 18 lb H2O/mol H2O = Say you have 100 ppmv of moisture in natural gas (let's call it N.G.). Once you know what "brand" of ppm you're dealing with, write it out fully and then do the units conversion. ppmv means parts per million by volume, which is identical to molar concentration ppmw means parts per million by weight (really mass). I greatly prefer specifying it that way over just plain ppm so as to avoid confusion. You may see your contaminant's concentration expressed as ppmv or ppmw. Less common (thankfully) would be mixed concentrations. In gas/vapor systems, molar (or volume) concentrations are the most common in liquid systems, mass concentrations prevail. This process is simply called water softening.There are several conventions for expressing concentrations of contaminants, and you should attempt to be specific. These devices are designed to reduce the water hardness from 200, 300, or even 400 ppm to below 60 ppm. You can find a list of the best water softeners here. Pretty much the only way that is very effective at softening water and eliminating all the problems that come with it is installing a water softener. You might not like it but fighting hard water is a smart long-term decision. Hard water will eventually lead to limescale build-up in your piping, washing machine, and so on, thereby limiting the lifespan of essential plumbing. The more concerning are the long term effects. Hard water with a high concentration of calcium and magnesium ions causes white stains pretty much everywhere.

The immediate effects of using hard water might be apparent on your skin or on your dishes, faucets. The easiest thing is to just ignore the problem. What To Do If You Find Out You Have Hard Water? Essentially, getting a 100+ ppm water hardness is not unusual it’s actually very common. More than 90% of people find that their water is either moderately hard, hard, or very hard.
If you measure that your water hardness is below 60 ppm or 3.50 GPG, you don’t have to worry about hard water. Mmol/L is a metric unit, usually in use outside of the US.įirst, you have to measure the water hardness with a water hardness test.

Here is the full water hardness scale, according to the USGS: Classification In the US, the unit of water hardness is usually parts per million (ppm) or grains per gallon (GPG). Internationally recognized water hardness scale recognizes 4 water hardness classes – from soft, moderately hard, hard, to very hard. Scale Of Water Hardness (From Soft To Very Hard Water) Here is a quick chart that gives you a spectrum of water hardness in parts per million (ppm): The water hardness scale is a benchmark on how hard our water is.

How to know if you have hard water? Simple: Limescale build-up in internal piping is extremely problematic.Īccording to the water hardness scale, more than 85% of US households have hard water in their piping. Example of white stains hard water causes. The damage to internal piping, appliances, limescale build-up, and skin irritation are just a few problems that hard water causes. Nobody wants to have hard water in the house.
