Recently, at the request of Mr. Li, a major client in Beijing, we tested a filter cartridge marketed as China’s “No. 1” purification brand—priced several times higher than ours. We sent the ChengRongTimes PVC-alloy ultrafiltration membrane cartridge and the competitor’s filter cartridge to a laboratory for comprehensive testing under identical membrane area conditions.
The results were clear: ChengRongTimes’s ultrafiltration cartridge delivered significantly higher performance, particularly in flow rate and purification efficiency, reinforcing its position as an unbeatable value leader in ultrafiltration.
Higher Flow Rate for Faster Clean Water Production
Flow rate is one of the most important performance indicators for an ultrafiltration cartridge, and it is closely related to inlet water pressure.
The test covered five pressure conditions: 0.2MPa, 0.25MPa, 0.3MPa, 0.35MPa, and 0.4MPa. Under every tested pressure condition, the ChengRongTimes PVC-alloy ultrafiltration membrane outperformed the competing brand by 150–190 liters per hour.
Higher flow rate means faster clean water production, making the cartridge particularly suitable for cooking, drinking, and other high-demand household water purification applications.
For example, when preparing 15L of water, enough for a 5-person dinner, at 0.25MPa, ChengRongTimes required only 1 minute 38 seconds, compared with 2 minutes 15 seconds for the competitor. This represents a 37.5% efficiency boost.
26.9%–50% Higher Purification Efficiency
The flow-rate advantage is supported by ChengRongTimes’s advanced ultrafiltration technology. Its PVC-alloy ultrafiltration membrane is designed to precisely block harmful bacteria, viruses, colloids, and suspended solids while retaining beneficial minerals and trace elements.
This filtration approach provides high water purification efficiency without unnecessarily removing beneficial minerals and trace elements, making ChengRongTimes’s ultrafiltration cartridge a practical solution for everyday drinking and household water purification.
Longer Cartridge Lifespan and Lower Replacement Costs
A high flow rate and stable purification performance can also contribute to a longer filter cartridge lifespan.
By processing larger volumes of water with balanced pressure distribution, the ChengRongTimes ultrafiltration cartridge is designed to resist clogging more effectively. Less clogging can reduce the frequency of filter cartridge replacement and help lower long-term water purification costs.
For buyers comparing ultrafiltration cartridges based on total operating cost, flow rate, purification efficiency, cartridge lifespan, and replacement frequency should all be considered—not just the initial purchase price.
Stable Performance Under Different Pressure Conditions
Consistent performance is essential for an ultrafiltration membrane cartridge. ChengRongTimes maintains stable performance across different inlet water pressure conditions, helping ensure consistent clean water output.
This stability is especially useful in different household water-use environments, including high-rise buildings with relatively low water pressure and periods of peak water consumption.
The test results across 0.2MPa, 0.25MPa, 0.3MPa, 0.35MPa, and 0.4MPa demonstrate the consistency of ChengRongTimes’s PVC-alloy ultrafiltration membrane under multiple pressure conditions.
ChengRongTimes: High-Performance Ultrafiltration at a Better Value
The comparison demonstrates the core advantages of the ChengRongTimes PVC-alloy ultrafiltration membrane cartridge: higher flow rate, higher purification efficiency, longer service potential, and stable performance across different pressure conditions.
With a 150–190 liters per hour flow-rate advantage, 37.5% faster production in the 15L test at 0.25MPa, and 26.9%–50% higher purification efficiency, ChengRongTimes provides a strong value proposition for customers looking for high-performance ultrafiltration cartridges and water purification solutions.
For customers comparing domestic and international filter cartridge brands, ChengRongTimes offers a practical combination of performance, reliability, and cost efficiency.
