Water is the essence of life, but in today’s fast-paced world, the safety of our drinking water is increasingly uncertain. Are you aware that the tap water we rely on daily carries health risks? Excessive heavy metal content in tap water can have detrimental effects on our well-being.
Unraveling the Sources of Heavy Metals in Tap Water
1. Industrial Pollution Discharge:
The discharge of heavy metal wastewater, including hazardous substances like Chromium (Cr), Cadmium (Cd), Copper (Cu), Mercury (Hg), Nickel (Ni), and Zinc (Zn), from industrial processes such as mining, machinery manufacturing, and the chemical industry, poses a severe threat to our water resources. This pollution has resulted in significant harm to both our environment and human health.
2. Faucets and Water Pipes:
Water pollution has reached alarming levels, even with diligent efforts by water treatment plants to remove harmful contaminants. Aging water pipes contribute to “secondary pollution” as they release varying amounts of heavy metals during water transportation. Furthermore, we cannot overlook the potential heavy metal contamination from faucets. Copper alloy faucets, commonly used today, contain copper, zinc, tin, iron, manganese, lead, aluminum, and other elements. Over time, lead leeks into the water, causing further contamination.
The Hazards of Excessive Heavy Metals in Drinking Water
Tap water can harbor an array of heavy metals, including mercury, chromium, cadmium, lead, cobalt, vanadium, antimony, manganese, tin, zinc, and arsenic. The hazards associated with elevated levels of heavy metals in water are numerous. They can lead to heavy metal poisoning, impair important organ functions, and damage the nervous system.
For instance, let’s consider the well-known effects of lead poisoning. Adults suffering from lead poisoning often experience symptoms such as fatigue, depression, heart failure, abdominal pain, and renal deficiency. Children, on the other hand, are significantly more vulnerable. Lead poisoning can cause irreversible damage to their intelligence, behavioral development, physical growth, and nervous, digestive, circulatory, and urinary systems.
Moreover, heavy metals are invisible and odorless, making them impossible to detect with the naked eye. Boiling water is ineffective in removing these contaminants and may even lead to chemical reactions that form harmful substances.
Effective Methods to Remove Heavy Metals from Water
1. Absorption Method:
The absorption method is widely used to combat heavy metal contamination. It involves utilizing materials with porous surfaces and strong absorption capabilities, such as activated carbon, minerals, and molecular sieves. While activated carbon is a popular adsorbent, its high cost and limited lifespan restrict its complete removal of heavy metals from water.
2. Electrolysis:
Electrochemical methods leverage the principles of electrolysis to enrich heavy metals through redox reactions occurring on positive and negative electrodes. The electrolysis method encompasses electrolytic precipitation and heavy metal recovery electrolysis, depending on the type of anode employed. However, this technique consumes substantial electricity and requires numerous iron plates. Furthermore, the separation of sludge poses challenges, leading to high operational costs.
3. Air Flotation Method:
The air flotation method involves the reaction between ferrous sulfate and heavy metal ions in an acidic environment, resulting in the formation of flocs in an alkaline environment. These flocs are then buoyed to the surface by countless fine air bubbles, clarifying the water. However, this method entails significant chemical consumption, often yielding suboptimal removal outcomes and generating substantial solid waste. The disposal of solid waste incurs high costs as well.
4. Extraction Method:
The extraction method introduces a substance that is insoluble in water but soluble in a solvent into the sewage during treatment. However, this approach is costly, as it requires the addition of solutes or extracts to effectively remove heavy metals.
5. Water Purifier Filtration Method:
The filtration method, commonly employed in water purifiers, offers a practical solution for heavy metal removal. Currently, reverse osmosis (RO) water purifiers are highly regarded. Water filtered through an RO membrane is devoid of harmful substances while retaining essential minerals vital for the human body. Drinking RO-purified water over an extended period does not have adverse effects on health.
