Our pp filter cartridge series features a reinforced central core and a melt-blown depth design with a progressive pore structure that effectively captures particles of various sizes, significantly improving impurity removal performance. In water treatment applications—especially in systems using Danfoss plunger pumps, which require a high level of pretreatment reliability—this pp filter cartridge is strongly recommended thanks to its absolute filtration capability, providing essential protection for the pump.
Additionally, this cartridge is ideal for front-end filtration in wine and beer production. Diatomite filtration equipment is commonly used in these industries, and leakage of diatomaceous earth powder can occur easily. This filter cartridge effectively intercepts diatomite particles, preventing contamination in downstream processes.
The integrated center core further enhances the structural strength of the filter, enabling it to withstand higher flow rates and pressure differentials.

FAQ
Has your company evaluated the economic benefits of the pretreatment system?
Yes. The pretreatment section accounts for about 20%–30% of the total investment of the RO system, but it significantly reduces long-term operating costs, including:
40%–60% reduction in membrane replacement costs;
10%–15% lower energy consumption (due to reduced fouling and lower pressure drop);
Cleaning frequency reduced from once per month to 2–3 times per year.
Our project is quite special. Is it possible to customize the security filter (cartridge filter housing) according to our required dimensions?
No problem. Just provide us with your drawing, and we will prepare our design based on your requirements. Production will only begin after you confirm the final design.
If I order the complete pretreatment section, will the media—such as activated carbon, quartz sand, etc.—be pre-filled in the tanks, or will they be shipped empty?
For smaller systems, such as 250 LPH to 1000 LPH, some units will be shipped with the media already filled.
For larger systems, we do not pre-fill the media. The customer will need to fill it on-site after receiving the equipment, because the media may compress and damage the distributor or the tank during transportation.
Do you have any additional services?
Yes, we provide a free goods inspection service. If your supplier is within 200 km of our company (Chengdu), even the transportation cost will be covered by us. If the distance is more than 200 km, only the transportation and hotel costs will be borne by you.
Can all your products accept OEM service?
Yes, for each item, there will be a minimum order quantity, and then we can produce an OEM order for you.
Can you source some other related products for us?
Yes, whether they are water- or wastewater-related products, we can source them for you. We have been working in the water and wastewater fields for more than 10 years.
