When water containing iron and manganese passes through the bed, it oxidized and precipitated by contact and hydrogen sulfide H2S gas eliminated by oxidation to sulfate and insoluble precipitate. Periodic regeneration cycle with a weak solution of potassium permanganate restore the oxidizing capacity of the bed.
The most common water problems is Hard water and are as follows.
Most of the earth’s water is groundwater. it travels through rock and soil picking up minerals, including calcium and magnesium along the way. These two contaminants produce is commonly known as “Hardness” in water. Hard water could be noticed easily on clogged pipes and appliances. Hard water mineral deposit can form in coffee makers and other plumbing equipment . A film layer could be seen on bathtubs or shower tiles due to hard water. Hard water can cause hair to be dull and limps and dry skin. Water heating costs could increase as a result of hard water. The calcium and magnesium in hard water act as many soaps, and detergent to reduce their cleaning capabilities. These hardness increase the cost of washing and reduces the lite of clothes also.
When water containing iron or manganese passes through the filter bed, birm acts as an insoluble catalyst to enhance the reaction between dissolved oxygen and iron compounds and produces ferric hydroxide which precipitates and easily filtered. Periodic automatic time clock backwash flushes cut the accumulated iron and manganese and the bed is ready to perform its function.
