Many of us might have heard about the Flint water crisis. What started as an experiment for a less expensive source of water, led to complications. The water that was sourced from Flint river proved to be impure. While it did have many impurities, the presence of an excess amount of lead in the water was a cause of major concern. Lead poisoning was no longer a story for people who were dependent on Flint water for their livelihood. We all know that excess lead in water could lead to a number of health complications. Children below the age of six are extremely vulnerable to lead poisoning. While Flint is just one of the many incidents that keep happening across the world, in this article, we will try and understand how good quality lead filter system can help in removing excess led from the water. We also will look at the various ways by which excess lead can be removed from drinking or potable water.
What Are The Symptoms Of Lead Poisoning
As mentioned above, lead poisoning is more pronounced in children below the age of six. They could suffer from various problems such as difficulty in learning, irritability, weight loss, loss of appetite, abdominal pain, nausea & vomiting, fatigue and sluggishness amongst other things. Some children may also complain about constipation, hearing loss while in rare cases, seizures could also be directly related to lead poisoning. Eating food that is treated with preservatives and colors could also result in lead poisoning.
Find If The Water Has Excess Amount Of Lead
While some amount of lead will always be there in the water, you should get in touch with your local water supplier. They will help you with a copy of the latest report on the quality of water. If the lead concentration in water is within the permissible limit, then you do not have any problem. However, if it is on the higher side then you must take steps to have them removed. Even otherwise, using a dialysis quality water filter is always recommended for homes. It helps to keep the water free from various contaminants including bacteria, harmful microorganisms and of course naturally occurring minerals and chemicals.
Methods Used For Removal Of Lead From Water
There are basically three methods by which it is possible to remove lead from drinking water. They are distillation, carbon filtration and reverse osmosis. We will look at each one of them briefly.
Distillation is effective but is a very slow process. It also required a lot of energy emanating from a heat source. Though it could be effective, it is not considered optimal for efficient removal of excess lead from water.
Carbon block filters are also used to remove lead from water. However, they get exhausted quite fast and therefore come with their own limitations and shortcomings. You could buy a carbon that theoretically may be suited for removing lead from 10000 gallons of water. However, after the first 2000 gallons, the efficiency of lead removal gets reduced quite significantly. Hence this also is not considered as a reliable method for removing lead from water.
Reverse osmosis is the most advanced and is considered to be the best option to filter household water not only from lead but also from other impurities and chemicals. This is a complex process where the water is pushed through a series of different types of filters. The membranes that make up the reverse osmosis system can remove lead and other impurities and contaminants. The impurities are flushed away and what you get is clean, safe and potable drinking water.
