Caused by the presence of calcium and magnesium. Hard water consumes soap before a lather will form and creates scale in boilers, water heaters, and pipes. 0 - 60 mg/L soft 61-120 mg/L moderate 121-180 mg/L hard >181 mg/L very hard Water Softener Calcium and Magnesium
Boiler Water Quality. Boiler Chemicals are used to ensure proper Boiler Water Quality in boilers. The below table is the Total Dissolved Solids or TDS, Alkalinity, and Hardness versus Boiler Pressure. First, knowing the water source is important, whether it is from ponds, rivers, ground wells, or city water. It is essential in determining the type of boiler water treatment chemicals needed.
Boiler water tests available The specific method of chemical treatment used varies with the type of boiler and the specific properties of the water from which the boiler feed is derived. This is very site specific but we have the testing capability to cover all your requirements. A boiler requires testing of three different water types as shown below
Dec 15, 2010 · Boiler Water Testing. Objectives of the Boiler Water Testing. 1)To monitor the condition of the boiler water. 2)To control the chemical dosing of the boiler. 3)To maintain the boiler in healthy state, around any possible seawater contamination. The first stage in the boiler water testing is to collect feed water sample from the boiler concerned.
Make-up Water – The boiler technician should check the make-up water daily. Key test parameters are hardness, alkalinity, and conductivity. Softener and/or RO unit – Test for hardness and conductivity based on softener capacity and gallons of make-up water. Test every shift if possible when you have reached 75% of softening capacity.
