The Hazards of Excessive Manganese in Drinking Water
Manganese has severe physiological toxicity. Long-term ingestion of low doses of excessive manganese in drinking water can cause chronic poisoning, leading to tremor paralysis and serious damage to the nervous system. According to research, excessive manganese can also damage the arterial intima and myocardium, forming atherosclerotic plaques, causing coronary artery stenosis and coronary heart disease. Excessive manganese intake can reduce the synthesis of “dopamine” in the brain. Early symptoms include fatigue, dizziness, headache, memory loss, muscle pain, mood instability, depression or agitation. Late symptoms include muscle stiffness, increased muscle tone, body tremors, and sometimes fever and breathing difficulties that do not respond to antibiotic treatment.
In terms of water supply network maintenance, manganese deposits on pipe walls, reducing drainage capacity. When sediment peels off or iron and manganese accumulate at the end of pipes, it can seriously affect water quality, causing “black water” or “yellow water”. In severe cases, it can block water pipes and outlet equipment. These problems can occur when manganese concentration in pipes reaches only 0.15mg/L.
Product Features: Manganese Sand Filter
The manganese sand filter is a type of filter that uses manganese sand as the filling material. It is beneficial for removing impurities in water. Its advantages include low filtration resistance, large specific surface area, strong acid and alkali resistance, and good anti-pollution performance. The unique advantages of the manganese sand filter lie in its adaptive operation achieved through optimizing filter media and filter design. The filter media has strong adaptability to raw water concentration, operating conditions, pretreatment processes, etc. During filtration, the filter bed automatically forms a loose upper layer and dense lower layer, which helps ensure water quality under various operating conditions. During backwashing, the filter media disperses fully, resulting in effective cleaning.
Manganese sand filters can effectively remove suspended solids in water and have significant removal effects on pollutants such as colloids, iron, organic matter, pesticides, manganese, bacteria, and viruses in water. They also feature fast filtration speed, high filtration precision, and large pollutant interception capacity.
