Water Filtration System for Villas: Efficiently Treating Calcium-Contaminated Water

I. Is Tap Water Contaminated with Calcium?

Contamination of tap water with calcium is no longer a strange phenomenon. The presence of calcium in water originates from the process of dissolving minerals in the limestone layer underground.

Sources of water commonly heavily contaminated with calcium include:

• Drilled well water: Deep drilled wells often contain many minerals as groundwater comes into contact with geological layers containing calcium and magnesium.
• Groundwater: Groundwater in many areas is also contaminated with calcium due to specific geological conditions.
• Tap water: Although treated, tap water in some areas may still contain calcium, especially in places using old and corroded water supply pipes.

II. Signs of Calcium-Contaminated Water

Calcium-contaminated tap water not only affects health but also causes many inconveniences in daily life. Therefore, identifying and treating calcium-contaminated water is essential to protect health and improve quality of life. There are several common signs to recognize water contaminated with calcium, including:

• White residue in the kettle after boiling water: When boiling water, you will notice a white residue at the bottom and inside the kettle. This is the calcium deposit when water is heated.
• Dry and brittle skin and hair: Calcium-contaminated water makes the skin dry and hair prone to tangling and becoming stiff after showering.
• Yellow stains on sanitary equipment: Sanitary equipment such as toilets, sinks, and faucets often develop yellow stains or dirty deposits.
• Decreased performance of washing machines and dishwashers: Calcium buildup in these appliances reduces cleaning efficiency, resulting in clothes and dishes not being as clean as desired.
• Unpleasant taste of water: Calcium-contaminated water often has an unpleasant taste, making it unenjoyable to drink.

III. What Are the Consequences of Using Calcium-Contaminated Tap Water?

Using calcium-contaminated water for a long time leads to many serious consequences, affecting not only health but also daily activities:

• Health impacts: Drinking calcium-contaminated water can lead to conditions like kidney stones, gallstones, and digestive issues. Excess calcium accumulation in the body can cause dangerous health conditions.
• Reduced durability of household appliances: Calcium buildup in household appliances such as kettles, washing machines, and dishwashers causes them to deteriorate quickly, reducing their lifespan and operational efficiency.
• Energy consumption: Calcium-contaminated water reduces the efficiency of household appliances, leading to higher electricity consumption and increased living costs.
• Using calcium-contaminated water for a long time can cause dry and brittle skin and hair, stiff and quickly yellowing clothes. These issues all contribute to a decreased quality of life.

IV. Installation of Toan A JSC's Whole House Filtration System

Since calcium-contaminated water is a common issue nowadays, there are many methods to reduce or treat this condition, ranging from simple methods like using sediment filters to more complex treatment systems. However, one of the effective and comprehensive solutions that many buildings, hotels, restaurants, or families living in villas choose is installing Toan A JSC's whole house filtration system.

1. What is Toan A JSC's Whole House Filtration System?

The whole house filtration system is a comprehensive solution that filters water right from the source, removing calcium and other heavy metals along with impurities from the household water source, ensuring clean water supply for the entire building. This system operates based on mechanical and chemical filtration principles, ensuring clean and safe water for all usage needs.

2. Structure of Toan A JSC's Whole House Filtration System for Buildings, Villas

Depending on the usage needs and daily water consumption of customers, the technical consulting team of Toan A JSC will study and install a whole house filtration system tailored to each unit, building, or household. In general, the structure of this system will include components such as: coarse filters, fine filters with details like control valves, water filtration materials, and 03 filter columns ensuring a filtration capacity from 1.5 - 3m3/h to provide enough water for household use, buildings. The roles of each component in the system are as follows:

• Coarse filter component: Removes impurities in water. This component consists of 3 filter columns:
  • Filter column 1: Removes heavy metals (iron oxide, manganese oxide, etc.) and suspended impurities causing an unpleasant odor in hard water. This filter column also removes impurities causing discoloration. The main filtration materials in this column are manganese sand, quartz sand, and gravel.
  • Filter column 2: Helps reduce various viruses, bacteria, impurities, odors, and colors in water, balancing the pH level. The main component of this filter column is activated carbon.
  • Filter column 3: Calcium and lime filter column using cationic particles that reduce water hardness by absorbing ions (Ca2+, Mg2+), then releasing Na+ ions to soften the water.
• Fine filter component: Consists of a 20-inch PP fine filter core with ultra-small filtration slits of about 5µm, removing suspended impurities larger than 5µm.

After passing through the filter columns of this whole house filtration system, water will go into a reservoir for water storage and distribution to various spaces in the building, villa. Water after passing through Toan A JSC's whole house filtration system will ensure purity, cleanliness, especially removing up to 99% of calcium, providing safe and pure water, meeting the QCVN 01:2018/BYT drinking water standard.

The whole house filtration system is not only suitable for households but is also widely used in manufacturing facilities, restaurants, hotels. Using this system helps improve water quality, ensure user health and protect household appliances.
