RCP400-60VPP Water Treatment Filter Product Specification
Product Introduction
The RCP400-60VPP is a high-performance polypropylene (PP) based water treatment filter element, engineered for professional industrial and commercial water purification applications. Adopting advanced melt-blown and precision forming technology, this filter integrates high structural stability and excellent contaminant removal capacity, with a customized 60VPP core design matching the RCP400 series housing compatibility. It is free of adhesive, heavy metal and other harmful additives, complying with international water treatment material safety standards, and is suitable for pre-filtration and fine filtration links of various water treatment systems, effectively reducing suspended solids, particulates and colloidal impurities in water without secondary pollution to the water body.
Filtration Precision
The RCP400-60VPP features a graded filtration precision design with a nominal filtration accuracy of 5 microns as the core precision, and the absolute filtration precision reaches 10 microns. The multi-layer gradient pore structure of the filter element enables step-by-step interception of impurities of different particle sizes, realizing high-efficiency capture of fine particulates while avoiding rapid blockage of the filter core, and ensuring stable filtration precision retention throughout the service cycle.
Flux
Under the standard operating condition of 25℃ ambient temperature and 0.2MPa inlet pressure, the pure water flux of the RCP400-60VPP is 400 L/h (liters per hour). The flux remains stable within the recommended operating pressure range (0.1-0.3MPa); when the water temperature is between 10-40℃, the flux changes in a linear and recoverable range with temperature, and the actual working flux can be adjusted according to the water quality turbidity and system design requirements without affecting the basic filtration performance.
Salt Rejection Rate
As a high-efficiency particulate filtration filter element, the RCP400-60VPP is optimized for physical interception of non-ionic contaminants, with a 98%+ salt rejection rate for colloidal salt and insoluble salt particulates with particle size above 5 microns. For soluble inorganic salts, the product is designed for pre-filtration matching with reverse osmosis (RO) and nanofiltration (NF) membrane systems, and can effectively reduce the salt particulate load of subsequent desalination membrane elements, improving the overall salt rejection efficiency of the whole water treatment system.
Pressure Drop
The initial pressure drop of the RCP400-60VPP is ≤0.02MPa under the rated flux and standard operating conditions. With the progress of filtration work and the gradual interception of impurities, the pressure drop of the filter element increases slowly; the recommended maximum allowable pressure drop is 0.1MPa, beyond which the filter element needs to be cleaned or replaced in time to avoid excessive pressure loss leading to reduced system operation efficiency and filter core structural damage.
Molecular Weight Cutoff (MWCO)
The molecular weight cutoff of the RCP400-60VPP is 100,000 Daltons (Da). This MWCO rating is precisely calibrated for the interception of macromolecular organic matter, colloidal particles and macromolecular impurities in water, which can effectively retain substances with molecular weight higher than 100,000 Da while ensuring the smooth passage of water molecules and small molecular inorganic substances, matching the pre-filtration requirements of medium and high precision water treatment systems.
Membrane Thickness
The RCP400-60VPP adopts a multi-layer composite PP membrane structure, with the total effective membrane thickness of 25mm. The surface filtration layer is a 5mm dense PP membrane for fine interception of small particulates, the middle support layer is a 15mm high-strength PP membrane with gradient pores for structural support and secondary interception, and the bottom base layer is a 5mm thick PP membrane for enhancing the pressure resistance of the filter element. The multi-layer thickness design balances filtration efficiency and mechanical strength, making the filter element resistant to extrusion and not easy to deform under high pressure working conditions.
Replacement Cycle
The recommended standard replacement cycle of the RCP400-60VPP is 3-6 months, which is determined based on the standard water quality condition (turbidity ≤5 NTU, suspended solids content ≤10 mg/L). For water treatment systems with high water turbidity (turbidity >5 NTU) or continuous 24-hour operation, the replacement cycle is shortened to 1-3 months according to the actual pressure drop and water quality test results; for low-turbidity pure water pre-filtration scenarios (turbidity ≤1 NTU), the replacement cycle can be appropriately extended to 6-8 months with regular backwashing and maintenance.
