HPR-MBR-II Reinforced PVDF/PET Hollow Fiber Membr | RFQ Sourcing Details

The HPR-MBR-II is a reinforced hollow fiber microfiltration membrane module for submerged MBR and water-filtration systems. Its membrane construction combines a modified PVDF functional material with a polyester (PET) support network pipe.

The module uses an ABS shell and a frame-style structure intended to simplify installation and maintenance. Published parameters for the HPR-MBR-II include a 1250 × 30 mm module specification, an effective membrane area of 10–35 m², a 1.5/2.6 mm membrane inner/outer diameter, and 0.1 μm filtration accuracy.

The stated operating method is submerged suction or siphon filtration, with water collection at the top and bottom and water production from both sides at the top. A φ24 connecting pipe is specified. The stated usable pH range is 2–12, with 6–8 identified as the optimal range.

The published temperature range is 10–40°C, with 15–30°C listed as optimal. Operating pressure is stated as 0.02 to -0.05 MPa, while the optimal range is listed as 0.02 to -0.03 MPa. The stated operating membrane flux is 10–30 L/m²·h. Recommended sludge concentration is 4–12 g/L, with 6–10 g/L identified as optimal.

Published oil limits are below 50 mg/L for animal and vegetable oils and below 3 mg/L for mineral oil;the corresponding optimal limits are below 30 mg/L and below 1 mg/L. The reinforced woven support structure is described as resisting fiber breakage, and monofilament tensile strength is stated as greater than 200 N.

The membrane is described as permanently hydrophilic and suitable for dry transportation and storage. Stated porosity is greater than 60%.

The module supports high-pressure water backwashing, and its arrayed fiber arrangement is designed to improve air scrubbing and water distribution while reducing the likelihood of sludge compaction.

Listed application fields include municipal sewage treatment, industrial park wastewater, rural decentralized sewage treatment, electroplating wastewater, metallurgical wastewater, printing and dyeing wastewater, reclaimed-water reuse, aquaculture tail-water treatment, black and odorous water treatment, and water-purification systems.

Custom module sizing and OEM branding are stated as available. Before procurement, the buyer should confirm the final effective membrane area and module dimensions for the selected configuration, as the product family covers multiple sizes.

The buyer should also obtain a project-specific operating design covering feed-water analysis, pretreatment, target permeate quality, sustainable design flux, aeration demand, backwashing parameters, chemical-cleaning limits, and expected membrane life.

Connection layout, cassette or frame integration, quantity, packaging, inspection criteria, replacement terms, and warranty coverage should be documented in the purchase specification before ordering.
