Some Main Questions To Consider When Specifying A Dosing Pump
When specifying a dosing pump for any type of chemical dosing applications there are some fundamental questions that you need to ask yourself. What is the type of fluid is being pumped?All materials which come in contact with the fluid must be compatible these include the dosing heads, diaphragms, valve balls, valve seats, piston seals […]
Stray Voltages in Water Treatment Applications (SV) General Information
Water treatment controllers approximate the TDS of the water through the use of a conductivity measurement. As the amount of dissolved solids in the system increases, so do the conductivity readings. Conductivity controllers pass a low-voltage AC signal across the conductivity electrodes to determine the conductivity of the water. When other voltages are present in […]
The Principles of Evaporative Cooling Towers
Cooling towers use the principle of evaporative or ‘wet bulb’ cooling in order to cool water. The main advantages over a conventional heat-exchanger are:- The main disadvantage of cooling towers is their need for careful maintenance to minimise the risk of water fouling and water-borne organisms e.g. Legionnaire’s disease. There are two main types of […]
