ChengrongTimes has a customer whose water source comes from a remote, heavily forested mountain area.<\/p>\n\n\n\n

Given the pristine natural environment surrounding the source, our customer believes that the water quality should be excellent.<\/p>\n\n\n\n

He did not want to use an RO water purifier, since he wanted to avoid removing the naturally minerals and trace elements from the water. <\/p>\n\n\n\n

Therefore, he come to ChengrongTimes to order a small batch of 0.01 \u03bcm smart-control ultrafiltration water filters. <\/p>\n\n\n\n

These ultrafiltration water filters for house were intended to remove sediment, colloids and other suspended matter, as well as microorganisms such as bacteria and viruses, while retaining its natural minerals and trace elements. <\/p>\n\n\n\n

This mineral-retaining filtered water is not only clean but also healther as it could retain naturally minerals and often tastes better than RO-purified water.<\/p>\n\n\n\n

Most people is not care much about drinking water. As long as it does not make them ill or cause stomach problems, they consider it acceptable.<\/p>\n\n\n\n

Affluent customers, however, often expect more than basic cleanliness. Besides cleanliness, they also wanna health, better taste. <\/p>\n\n\n\n

When the source water is already with high quality, they may see little reason to use reverse osmosis water filters to turn it into the same standardized purified water available everywhere.<\/p>\n\n\n\n

That was why this customer placed his order to ChengrongTimes 0.01 \u03bcm smart ultrafiltration water filters. His aim was to address turbidity-related problems in the spring water, but retaining the natural mineral and trace elements.<\/p>\n\n\n\n

We already have many customer cases showing that when using the ultrafiltration water filter for house can provide an excellent whole house water filtration performance and results.<\/p>\n\n\n\n

After all, Chengrong Ultrafiltration Factory has specialized in inline ultrafiltration water filters for 19 years. Mountain spring water and well water are among the main applications of our whole house water filters<\/a><\/strong>, and the results have consistently been very good.<\/p>\n\n\n\n

However, shortly after the customer\u2019s ultrafiltration water filters were put into operation, he sent me a message saying that something was wrong with the ChengrongTimes water filter for house.<\/p>\n\n\n\n

The spring water filtered by the water filters for house was still yellow.<\/p>\n\n\n\n

At first, I suspected that the whole house water filtration system<\/a><\/strong> might have been knocked or damaged during transportation, compromising the internal seals and allowing untreated water to bypass the ultrafiltration membrane and mix with the filtered water.<\/p>\n\n\n\n

Based on my experience, this type of internal bypass is usually caused by a loose component somewhere inside the water filters for house. In such a case, even if something had become loose, it would not have been a serious problem and would be solved easily.<\/p>\n\n\n\n

I therefore asked the customer to follow my instructions and check whether the relevant components and connections were properly sealed.<\/p>\n\n\n\n

The inspection showed that there was nothing wrong with the ultrafiltration system. All the components were secure, and the seals were in good condition.<\/p>\n\n\n\n

But if there was nothing wrong with the equipment, why did the water filters for house appear to have failed?<\/p>\n\n\n\n

If the water filter for house system was operating correctly, why was the filtered spring water still yellow?<\/p>\n\n\n\n

Under normal circumstances, ultrafiltration systems perform extremely well when clarifying turbid natutral water. No matter how cloudy the raw water is, it normally becomes crystal clear after ultrafiltration.<\/p>\n\n\n\n

This time, however, the result was completely unexpected.<\/p>\n\n\n\n

Since we could not solve the customer\u2019s problem through online communication, I decided to visit the site in person.<\/p>\n\n\n\n

I immediately booked the earliest available flight on my phone, which would allow me to reach the installation site the following day.<\/p>\n\n\n\n

For the past 19 years, Chengrong Factory has followed an after-sales service standard of responding within 20 minutes, providing a proposed solution within two hours, and reaching the customer\u2019s site within two days whenever an on-site visit is required.<\/p>\n\n\n\n

More importantly, the customer had purchased a ChengrongTimes smart ultrafiltration water filter. Whether I looked at the situation from the customer\u2019s perspective or from the perspective of the ChengrongTimes brand, I knew I needed to visit the site and find out exactly what was happening.<\/p>\n\n\n\n
