and air quality In this course‚ we will discuss the reasons and means for controlling scale‚ corrosion and biological fouling. Critical Parameters The critical parameters for cooling water are: conductivity‚ total dissolved solids (TDS)‚ hardness‚ pH‚ alkalinity and saturation index. Conductivity and Total Dissolved Solids (TDS) Conductivity is a measure of the ability of water to conduct electrical current and it indicates the amount of the dissolved solids

I gave her an inner strength to endure childbirth and the rejection that many times comes from her children. I gave her a hardness that allows her to keep going when everyone else gives up‚ and take care of her family through sickness and fatigue without complaining. I gave her the sensitivity to love her children under any and all circumstances‚ even when her child has hurt

of the Upper Nepean Catchment. The following is a summary of factors that affect water quality. Water may contain several ions‚ namely anions and cations which are toxic to humans. Hardness is the scum on water surface from significant concentrations of calcium and magnesium ions. Total dissolved solids is the measure of dissolved solids that are ionic in water. Turbidity is the presence of suspended solids in water which reduces penetration of light‚ resulting in a decrease concentration of
