Tubular Membrane

Membrane-Based Solutions for Suspended Solids

Product Description

Tubular membranes are designed for applications involving liquids with high suspended solids (SS) or solid content. They utilize adjustable high cross-flow velocities to achieve optimal operating conditions, thereby extending the membrane’s lifespan. Thanks to their design, tubular membranes are easier to clean, making them ideal for handling challenging filtration processes.

From fine particulates to heavy sludge, our tubular membranes handle it all, delivering uncompromised performance for reliable wastewater treatment solutions.

Tubular Membrane is a type of membrane filtration technology where the membrane is configured in long tubes. It is constructed from materials such as ceramics, polymers, or composites. Tubular membranes are particularly suited for applications requiring high fouling resistance and the ability to handle high solids concentrations.


The flow channel can be customized between 6 mm and 12.5 mm to meet specific liquid requirements. Additionally, tubular membranes offer convenient cleaning, easy maintenance, and the ability to operate independently.

Tubular membranes are commonly used in ultrafiltration (UF) and microfiltration (MF) processes. They are well-suited for applications that involve treating water with a high concentration of suspended solids or viscous fluids, such as landfill leachate, RO Concentrate, Cooling Water Softening, Acid and Alkali Recovery, Fruit and Vegetable Juice Separation and Concentration.

Tubular membranes apply in various industries such as food and beverage processing, pharmaceuticals, and municipal water treatment, industrial waste water treatment.

Most Frequently Asked Quesiton

What are tubular membranes from Suntar made of?

Our tubular membrane is made from PVDF materials for enhanced durability and chemical resistance.

Tubular membranes operate using crossflow filtration, where feedwater flows tangentially across the membrane surface, reducing fouling while allowing permeate (filtered water) to pass through

Yes, they are ideal for streams with high solids, fats, oils, or grease due to their robust design and ability to handle high fouling loads.

Ceramic tubular membranes can withstand aggressive cleaning chemicals, high temperatures, and extreme pH conditions.

Cleaning frequency depends on the feedwater quality and fouling tendencies but typically ranges from weekly to monthly.

Fouling may include:

  • Scaling (e.g., calcium, magnesium deposits)
  • Biological fouling
  • Organic fouling
  • Particulate depositio
