PHF-80-V UF Membrane Mann+Hummel Equivalent

Product Introduction

The PHF-80-V Ultrafiltration (UF) Membrane is a high-performance industrial-grade membrane module engineered as a direct equivalent to the Mann+Hummel PHF-80-V. This membrane offers outstanding filtration efficiency, chemical resistance, and mechanical durability, making it a dependable choice for water and wastewater treatment across a wide range of industrial and municipal applications.

Manufactured using advanced hollow fiber membrane technology, the PHF-80-V ensures consistent removal of suspended solids, bacteria, and viruses. It is especially suited for use in pretreatment for reverse osmosis (RO) systems, industrial process water recovery, and municipal drinking water systems. The module supports both backwash and chemically enhanced cleaning (CIP), enabling long operational life and high recovery rates.

Working Principle

The PHF-80-V UF membrane works on the outside-in filtration principle using hydrophilic hollow fiber membranes made of Polyvinylidene Fluoride (PVDF). Here's how the filtration process works:

1.    Feedwater Flow: Untreated water is introduced into the outer side of the hollow fibers (shell side).

2.    Filtration Action: Water penetrates the microporous membrane layer (nominal pore size ~0.03 µm), while contaminants such as colloids, bacteria, viruses, and suspended solids are retained on the outer surface.

3.    Permeate Collection: Clean water flows through the inner fiber lumen and is collected as permeate.

4.    Cleaning Cycles: Regular backwashing and periodic chemical cleaning help maintain high permeability and performance.

This method ensures stable operation even under varying feedwater quality and reduces membrane fouling for extended lifespan.

Technical Parameters

Applications

1. Municipal Water Treatment

The PHF-80-V module is ideal for use in drinking water treatment plants. Its fine filtration ensures the removal of pathogens, suspended solids, and turbidity, resulting in safe and clear water.

2. Wastewater Reuse

UF membranes are essential in advanced wastewater treatment and water reuse systems. This module helps in reclaiming high-quality effluent for non-potable applications like irrigation, industrial processes, and toilet flushing.

3. Industrial Process Water

In industries such as electronics, food and beverage, textiles, and chemicals, the PHF-80-V provides ultra-clean water needed for sensitive operations.

4. Pretreatment for Reverse Osmosis

Reduces SDI (Silt Density Index) of feed water and protects RO membranes from fouling, improving the efficiency and lifespan of downstream desalination or filtration systems.

5. Seawater Desalination

As a pretreatment step in SWRO (Seawater Reverse Osmosis), it improves system efficiency by minimizing organic and particulate load.

6. Cooling Towers and Boilers

Used for purifying make-up water and reducing blowdown frequency, resulting in energy and water savings in HVAC and power plant operations.

FAQ

Q1: Is the PHF-80-V UF module compatible with Mann+Hummel systems?
Yes. This module is fully compatible and interchangeable with the original Mann+Hummel PHF-80-V membrane modules.

Q2: What type of water sources can it treat?
The module is suitable for surface water, groundwater, seawater, industrial wastewater, and tertiary effluent.

Q3: What is the expected lifespan of this membrane?
Typically 3–5 years depending on the feedwater quality, cleaning frequency, and operating conditions.

Q4: Does this membrane remove viruses and bacteria?
Yes. With a nominal pore size of 0.03 µm, it achieves >4 log removal of bacteria and >5 log removal of viruses.

Q5: What cleaning methods are supported?
It supports backwashing, air scouring, and chemical cleaning with common agents like sodium hypochlorite, citric acid, and NaOH.

Q6: Can it handle high-TSS (Total Suspended Solids) waters?
Yes. The outside-in flow design accommodates higher solids loading and makes it more resistant to fouling.

Q7: How often should I perform chemical cleaning (CIP)?
CIP is generally recommended every 1–4 weeks depending on fouling rate and operational parameters.

Q8: What are the benefits of using PVDF membrane material?
PVDF offers excellent chemical resistance, long-term durability, and resistance to biofouling compared to other polymer materials.
