Parts per million
Planned Preventative Maintenanceschedule of tasks that keep the air handling unit efficient, daily/month/yearly etc.
to treat what? to form chloramines or th ebreakpoint the ammonia? Two possibilities with two different answers.
Use a chemical called "sodium bicarbonate" or "alkalinity up" - the dosage is 1.5 lbs for every 10000 gallons and 10 ppm. (So, 1.5*(gallons / 10000)*(ppm increase / 10)=amount) Mix with water in a large bucket and pour it around your pool.
100 ppm is worse than 50 ppm. The higher the ppm value, the more concentrated the substance is in the solution. In this case, a concentration of 100 ppm is twice as much as 50 ppm.
ppm
Zn < O.6 ppm Fe < 4.5 ppm Mn < 2.0 ppm Cu < 0.2 ppm
115 ppm is 0.0115%.
5 ppm (parts per million) is larger than 2 ppm. PPM is a measurement that indicates the concentration of one substance in a million parts of another, so a higher number indicates a greater concentration. Therefore, 5 ppm represents a higher quantity than 2 ppm.
ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.
0.5Mm = 50 PPM
Multiply ppm by 10000.
46 ppm is 0.0046%
0.110 ppm = 0.000011%
1 percent is 10,000 ppm .06 percent = (.06 x 10,000) = 600 ppm 90 ppm = (90 / 10,000) = 0.009 percent 0.06 percent is not the same thing as 90 ppm. This is not a math problem. You have to change the material. That's a chemistry problem.
