PPM is a term used in chemistry to denote a very, very low concentration of a solution
By definition, a Liter of water weighs 1 kg (1 kilogram or 1000
grams).
An 1 mg (1 milligram or 1/1000 of a gram)
Therefore 1 mg = 1/1,000,000 of a kg.
So, based on above data: 1 mg/L = 1 mg/kg = 1 mg/million mg =
ppm.
mg/L =ppm

In clinical applications, the unit parts per million (ppm) is used to express very small concentrations of solute, where ppm is equivalent to 1 mg of solute per 1 L of solution. Calculate the concentration in parts per million for cach of the solutions.

1. An effluent water contains significant quantities of non-emulsified oil with a concentration of 176 mg/l. In order to maintain the concentration of the oil below 25 mg/l, alum with a dosage of 35mg/l was used. Based on the preliminary experiments it was found that every gram of alum produces 0.65 g of sludge. The weight percentage of sludge in the effluent is 2.75. The flow rate of oily effluent water to the treatment unit is 0.75 m3/min at 30°C....
