Nearly all water in the world contains contaminants Many dissolved minerals, carbon compounds, and microbes find their way into drinking water Pollutants in drinking water may affect household routines and human health The only way to ensure safety of your water supply is to have a periodic laboratory water analysis doneWater Testing Parameters: Water Testing Parameters Color Color in water may be due to the inorganic ions, such as iron and manganese, humus and peat materials, plankton, weeds and industrial wastes. Odor Odor is recognized as a quality factor affecting acceptability of drinking water. Most organic and some inorganic chemicals contribute odor. Turbidity The Turbidity in water is the reduction of transparency due to the presence of particulate matter such as clay or silt, finely divided organic matter, plankton or other microscopic organisms.Water Testing Parameters: Water Testing Parameters Manganese The intake of manganese can be high as 20 mg/day without apparent ill effects. It should be noted that manganese may be objectionable to consumers if it is deposited in water mains and causes water discoloration Iron Anaerobic ground waters may contain iron up to several milligrams per liter without causing discoloration or turbidity in the water. Calcium Calcium is a major constituent of various types of rock. It is one of the most common constituents present in natural waters ranging from zero to several hundred milligrams per liter.Water Testing Parameters: Water Testing Parameters pH value pH value is the logarithm of reciprocal of hydrogen ion activity in moles per liter. In water solution, variations in pH value are mainly due to hydrolysis of salts of strong bases and weak acids. Alkalinity Alkalinity of water is its quantitative capacity to react with a strong acid to a designated pH. Excess alkalinity in water is harmful for irrigation which leads to soil damage and reduce crop yields. Conductivity Specific conductance yields a measure of water’s capacity to convey an electric current.Important Water Analysis Equipment: Important Water Analysis Equipment Total Organic Carbon Analyzer (TOC) A total organic carbon analyzer determines the amount of carbon in a water sample. There are two types of analyzers. One uses combustion and the other chemical oxidation. pH Analyzer Water pH testers and analyzers help analyze pH levels and detect faults in systems with electronic pH meters.Important Water Analysis Equipment: Important Water Analysis Equipment Water Desalination Equipment The parameters measured in Desalination instruments include Alkalinity, (COD), Conductivity, Dissolved Oxygen, Water Hardness, Iron, Manganese, Turbidity in water etc.Important Water Analysis Equipment: Important Water Analysis Equipment ORP Meters ORP meters measure the very small voltages generated when the measuring probe is placed in water in the presence of an oxidizing agent.Thank You: Thank You You do not have the permission to view this presentation.
