ICT is made up of information technology (storage tanks) and communications technology (pipes). Information (stored water) is stored using information technology (storage tanks) and a communication (flowing water) reaches the recipient through communications technology (pipes).
The Brinell hardness test is commonly used to determine the hardness of materials like metals and alloys. The test is achieved by applying a known load to the surface of the tested material through a hardened steel ball of known diameter. The diameter of the resulting permanent impression in the tested metal is measured and the Brinell Hardness Number is calculated as. BHN = 2 P / (Ï D (D - (D2 - d2)1/2)) (1). where.
Just as salt dose and brine concentration has an impact on a system efficiency, the rate at which brine is introduced will also have an impact. For a given salt dose and concentration, the brining rate will determine brine contact time with the resin. Increased contact time will increase the capacity and efficiency of the softener system; therefore, the slower brine can be introduced the better. There are practical limitations to how low the flow rate can go.
