How to Choose a Reliable Central Water Purification or Central Water Softening System?

How to Choose a Reliable Central Water Purification or Central Water Softening System? Most People Are Doing It Wrong!
Depending on the filtration level and specific functions, different water purification devices need to be installed at various stages of a home’s water system. Today, let’s take a look at the differences between central water purification and central water softening systems.

1. What Are Central Water Purification and Central Water Softening Systems?
A central water purification system is a secondary purification device installed on the main water line after the pre-filter. Its primary function is to remove colloids, bacteria, impurities, rust, silt, and certain organic substances and compounds from the water. Similar to a central air conditioning system, a central water purification system ensures that purified water flows from every faucet in the home, providing clean water for the kitchen, bathroom, balcony, living room, and other areas. This meets all household water needs, including drinking, cooking, washing, and bathing.
Central Water Softener: A third-stage purification device installed on a branch line downstream of the central water purifier. The water softener alters water hardness by removing calcium and magnesium ions, while also adsorbing excess iron ions. It achieves a high removal rate for hardness (water alkalinity), providing comprehensive softening for the household’s bathing water. It is typically used for daily hygiene, bathing, and laundry.

2. Why Install a Central Water Purifier and Central Water Softener?
Central water purifiers have a high flow rate, enabling them to supply water throughout the entire home, earning them the title of “central whole-house water purifiers.” Home central water purifiers introduce a new concept in water usage, simultaneously meeting both household drinking water and general domestic water needs. For most families, this represents a new approach to water treatment.
In terms of filtration precision, central water purification has achieved a high standard. The water quality after filtration by a central water purifier is excellent, making it an outstanding choice for household use.

Central water softeners are an excellent solution for water used in personal hygiene, with their primary function being to soften the water. Using softened water saves resources and eliminates many hassles. Washing your face with softened water helps lock in moisture, making your skin appear more youthful; showering with softened water nurtures skin health and keeps it smooth and supple; and washing clothes and towels with softened water leaves them clean, soft, and looking as good as new.

Soft water eliminates safety hazards and equipment wear caused by limescale in downstream water-using appliances, preventing scaling and blockages in wall-mounted boilers, radiators, water heaters, and solar water heaters, thereby extending their service life. When used with bathroom fixtures (such as glass shower enclosures, mirrors, bathtubs, and toilets), soft water minimizes the formation of stubborn white stains and rust spots that are difficult to clean.

For women and those with high standards for quality of life, a central water softener is indispensable.
If there are no special requirements for non-potable household water, central water purification and central water softening systems can be installed selectively; however, if budget allows, installing both is recommended.

After all, a central water filtration system effectively removes impurities such as colloids and certain compounds from the water, resulting in a purer taste and better water quality; it also provides greater peace of mind when washing fruits, vegetables, and dishes. Softened water reduces energy consumption, significantly improves the efficiency of water heaters, removes scale from pipes, increases water flow and pressure, and effectively extends the service life of other water-using appliances.

3. How to Choose Central Water Purification and Central Water Softening Systems

If you choose to install a central water purification system, the following four points must be considered.

First, Material Composition
As with other water purification equipment, the materials used in central water purification systems must meet food-grade standards to ensure product stability. Additionally, the system must undergo rigorous water hammer testing before leaving the factory to effectively withstand the damage caused by water hammer. Water inlet and outlet connections must maintain the system’s密封 integrity and enhance its pressure resistance. Regarding filter cartridges, food-grade ultrafiltration membrane fibers—safe and additive-free—are the ideal choice for central water purifiers.

Second, Filtration Method
Currently, central water purifiers on the market can be categorized by filtration method into non-ultrafiltration membrane systems and ultrafiltration membrane systems. If the local water’s TDS value is above 80, a central ultrafiltration water purifier is recommended; if the TDS value is below 80, a central water purifier using activated carbon is sufficient.
Central ultrafiltration water purifiers offer high filtration precision and a long service life.

Third, Water Flow Rate
Since central water purifiers are installed on the main water supply line, household water usage must be carefully considered to determine the appropriate flow rate. Generally, a flow rate of 3,000 L/h is sufficient for a 100-square-meter home; however, duplexes and townhouses may require the installation of two 3,000 L/h central water purification units.

Fourth, Service Life
Water purifiers typically specify their rated total filtration capacity. Service life varies by model. Failure to replace filter cartridges in a timely manner may cause previously filtered substances to backflow, contaminating the water quality.

A central water softener can be selected to complement a central water purifier. If you choose Shibaokang’s central water purifier, it is advisable to also select a Shibaokang brand central water softener. If equipment from different brands is used, performance may be compromised.

Key considerations when selecting a central water softener include:
1) Based on the operating principle of the central water softener, can it seamlessly perform softening, backwashing, brine regeneration, salt tank refilling, and rinse cycles? More importantly: Does it feature a separate salt tank (Shibokang water softeners use a separate salt tank)?
2) Can the system be intelligently programmed to automatically schedule backwash cycles, ensuring optimal softening performance? Does it use high-quality resin (which has strong exchange capacity, is resistant to damage, and has a normal service life of several years)?
3) Does it allow monitoring of the unit’s operational status? Does it feature automatic backwashing to prevent clogging, eliminating the need for manual intervention?
4) Does it feature microprocessor-controlled regeneration technology? This technology ensures thorough resin regeneration, guarantees high-quality softened water, and effectively extends the resin’s lifespan.
