Water filtration systems use reverse osmosis to filter out impurities from water. They work by forcing water through a membrane filter where contaminants such as bacteria, viruses, heavy metals, and even chlorine are removed.
Lead is a toxic metal found naturally in rocks and soil. When exposed to air, the lead becomes airborne and can enter our bodies via inhalation. This is why it’s important to make sure that any water source you drink has been purified before drinking it.
In this article, I’ll explain how lead gets into drinking water and how reverse osmosis removes lead from drinking water.
How does lead get into your drinking water?
Lead enters our drinking water in two ways: 1) old plumbing materials and 2) natural sources. Old plumbing materials include lead pipes and lead solder. Natural sources include naturally occurring minerals in groundwater.
Old plumbing materials are slowly deteriorating and releasing lead into our drinking water. These pipes were installed before regulations required testing for lead levels. Even though the pipes are no longer being used, they continue to release lead into our drinking water until they are removed and replaced.
Natural sources of lead include naturally occurring minerals in groundwater. Some of these minerals are dissolved in the water and released into the air. Once the water evaporates, the lead settles out onto land surfaces where it becomes part of the soil. Over time, rainwater picks up the lead and carries it into streams, lakes, rivers, and eventually into our drinking water.
How do you know if LEAD is in your water?
There are two main types of tests that you can run to determine whether there is lead in your water. One is called a “total dissolved solids” test, and the other is called a “lead ion concentration” test. Both tests will tell you how much lead is present in your water.
A total dissolved solids test measures the number of minerals in your water. These include calcium, magnesium, sodium, potassium, chloride, bicarbonate, sulfates, nitrates, phosphates, carbonates, silica, iron, manganese, copper, zinc, arsenic, selenium, fluoride, and others.
A lead ion concentration test measures the amount of lead ions in your water. Lead ions are the toxic form of lead, and they are usually found in older homes where lead paint was used.
Impact of Lead Poisoning on Our Bodies
Lead poisoning is a serious problem that affects millions of Americans every year. Even though the lead was banned decades ago, it still exists today. And unfortunately, children are especially vulnerable to lead poisoning.
Children under six years old are particularly susceptible to lead poisoning. Exposure to lead can cause anemia, weakness and kidney and brain damage, and even death. High levels of lead exposure can cause death, and very high levels of exposure can cause miscarriage or birth defects.
Does Reverse Osmosis Remove Lead?
Lead is a heavy metal that can cause serious health problems. You should never drink water that has high levels of lead in it. But did you know that reverse osmosis systems can actually remove lead from drinking water?
That’s right! Reverse osmosis systems will remove common chemical contaminants, including sodium, chloride, iron, copper, chromium, and lead. And since lead is a heavy metal, it tends to concentrate in places where there are lots of minerals, such as pipes or plumbing fixtures.
How Much Lead Does Reverse Osmosis Remove?
Reverse osmosis systems remove almost 100% of lead from water, but there’s still a small amount left behind. You can find out how much lead remains after using a reverse osmosis system here.
Lead is a heavy metal that accumulates in our bodies over time. Exposure to high levels of lead can damage brain development, cause learning disabilities, and even result in death.
That’s why it’s important to know how much lead is removed by your reverse osmosis system. If you’re concerned about lead in your tap water, then you might consider investing in a reverse osmosis water filtration system.
How Does Reverse Osmosis Remove Lead?
Reverse Osmosis (RO) removes contaminants from water including lead. It works by forcing water through a semi-permeate membrane that rejects any particles larger than 0.0001 microns (one ten-thousandth of a millimeter), which is small enough to prevent lead from passing through.
But there are several factors that affect how well a reverse osmosis system will work. Water pressure, solute concentration, and quality of raw water are among the main ones.
Water pressure is the force exerted by the water pushing against the membrane. Higher pressures mean more force is applied to the membrane, causing it to become less permeable. Lower pressures mean less force is applied to the membranes, allowing more contaminants to pass through.
Solute concentration refers to the number of dissolved ions present in the water. High concentrations of certain ions, such as calcium, magnesium, sodium, chloride, sulfates, nitrates, and bicarbonates, can cause problems with reverse osmosis systems.
The quality of raw water is also important. Raw water should be free of suspended matter, bacteria, sediment, and other contaminants. These can clog the pores of the membrane, reducing its effectiveness.
What Else Does Reverse Osmosis Remove?
Reverse osmosis removes many types of dissolved and solid materials from water. But there are still some contaminants that will remain in the treated water. These include lead, arsenic, fluoride, radium, pesticides, herbicides, bacteria, viruses, cysts, and molds.
So if you’re concerned about drinking water safety, then you might want to consider getting a reverse osmosis system installed in your home or office.
FAQs
Does activated carbon remove lead?
Activated carbon (AC) is among the most effective methods available for removing lead from water.
How can you remove lead from water?
Reverse osmosis can remove up to 99.1% of the lead from drinking tap or bottled water.
What does lead do to our health?
Lead poisoning can be dangerous if not treated promptly. It causes anemia, weakness, and even death.
Conclusion
Reverse osmosis systems are an excellent way to purify water. They are effective at removing contaminants such as heavy metals, bacteria, and viruses. However, they cannot remove lead.
Lead poisoning is caused by ingesting lead-based paint, drinking contaminated water, eating food containing high levels of lead, breathing air polluted with lead dust, or even inhaling fumes from certain paints.
It is possible to reduce the amount of lead in your home by using a reverse osmosis system. However, it is still impossible to completely eliminate lead from your home.
