Total measured oil in the water after the water cleaning process, but before it is discharged from the installation The amount of ammonium found in the water sample. The amount of total organic carbon found in the water. The water is under high temperature and the carbon left is measured The amount of Fenol found in the water sample. The amount of Glycol found in the water sample. The pH value of the treated water. The pH value is best given as a value, with no unit of measure, since there are no variations from the pH. The temperature of the water before it is discharged. Total measured residual clorines in the water after the water cleaning process, but before it is discharged from the installation. Total measured Oxygen in the water after the water cleaning process, but before it is discharged from the installation. A measure of the cloudiness of water caused by suspended particles. A measure of the number of particles in water as measured by a coulter counter. Any comment that may be useful in describing the water quality. There can be multiple comments. The unique identifier of the recurring element.
