Ceramic filter media are used in many water treatment products, including drinking water filters, hydrogen water systems, shower filters and other functional filtration products. While choosing the right type of ceramic media is important, the way water interacts with the media can also influence its performance. One important factor is contact time, which refers to how long the water remains in contact with the ceramic media during treatment.
Different filtration systems create different contact conditions. A gravity-fed filter may allow water to move slowly through the media, while a shower filter or high-flow cartridge may provide much shorter contact time. The amount of ceramic media, particle size, cartridge structure and water flow can all affect this interaction. For this reason, the same ceramic media may produce different results when used in different filtration products.
Contact time can be particularly important for functional ceramic media designed for hydrogen release, mineralisation, alkalinity or other water conditioning applications. Using more ceramic media does not necessarily guarantee better performance if water passes through the system too quickly. Manufacturers should therefore consider media quantity, flow rate and cartridge design together rather than evaluating each factor separately.
Zhangqiu City Longxin Corundum Products Co., Ltd. manufactures hydrogen, antibacterial, alkaline, adsorption, mineralisation and multifunctional ceramic filter media for different water treatment applications. For OEM and private label projects, we can support customers in selecting suitable ceramic media specifications according to their filtration system and application requirements. Testing the media under realistic operating conditions can help manufacturers develop more suitable and consistent water treatment products.
