Membrane Filtration

Spiral Wound Membrane

Suntar provides spiral wound membrane equipment/systems with a variety of filtration accuracy for different requirements, including spiral wound membrane systems in the range of microfiltration (MF), Ultra-filtration (UF), Nanofiltration (NF), and Reverse Osmosis (RO).

Typical spiral wound NF membrane equipment/systems are suitable for desalination, reduction of monosaccharides, and concentration processes.

Reverse Osmosis (RO) water treatment technology is well-known and widely used for pure or ultra-pure water production in all kinds of applications that requires pure or ultra-pure water.

Ceramic Membrane

Porous ceramic membranes available with a pore size ranging from 0.01 to 10 μm cover microfiltration and ultrafiltration. The membranes with different geometry can be adapted according to the viscosity and the suspended solids content of the feed solution to achieve the requirement of specific clarification and separation.

Principal Advantages
Long life-span
Highly chemical resistant
Full automatic control
High concentration factor, low water consumption, and small waste discharge
Applicable for filtration at high temperature
Typical Applications
Filtration of fermentation broth of amino acids (like lysine, threonine), organic acid (like lactic acid, succinic acid), etc
The concentration of reducing gel, etc
Clarification & Filtration of food & beverages (like fruit juice, plant extracts)

Flat Sheet Ultrafiltration (UF)

Suntar flow-cel flat sheet membrane separation technology has broken through the bottleneck of traditional filtration and separation technology in the fermentation industry. Our technology ensures a better filtrate quality at lower running costs. Nearly 400 sets of Suntar Flow-Cel UF systems with a total membrane area up to hundreds of thousands of square meters have been sold and installed with a handling capacity of over 10,000 tons feed per day.
Principal Advantages
High filtration accuracy and excellent filtrate quality
Strong fouling resistance and easy cleaning
Capable to treat fluids with high viscosity or high suspended solids
Modular design
Full automatic control
Typical Applications
Filtration of fermentation broth of amino acids (like lysine, threonine) and organic acid (like lactic acid, succinic acid)
Removal of bacteria, protein, etc. for process liquid

Hollow Fiber Membrane

Hollow Fiber membrane is a kind of porous homogeneous membrane, which made of PS / PVDF / PAN / PVC by a special process. The pore size range is from 3 KDa to 0.45 μm, which covers microfiltration and ultrafiltration. The membranes with different micro-tube diameters can be adapted according to the viscosity and the suspended solids content of the feed solution to achieve the requirement of specific clarification and separation. Inside–out filtration mode with high crossflow velocity prevents membrane fouling, which is suitable to use for the concentration and purification of highly concentrated liquid.
Principal Advantages
High permeate flux
Tough and reliable material
Low energy consumption
Sharp pore distribution
Chemical resistance, easy to clean
Applicable for filtration at high temperature
Typical Applications
Clarification & Filtration of glucose, beverages, seasonings, wine, etc
Filtration of fermentation broth, clarification, concentration & desalination for protein enzyme, etc

Tubular Membrane

Tubular membranes are particularly suited to fluids with high viscosity and/or suspended solids and are easy to clean due to their wide flow channels. Pre-treatment requirements are minimal.

Flow channel can choose from 6mm to 12.5mm, according to the liquid specification. And filtration accuracy is available across the full spectrum of membrane processes from Microfiltration to Reverse Osmosis.

Principal Advantages
Simple pretreatment
High concentration factor
Fouling resistance, easy to clean
The lower module packing density
Typical Applications
Filtration & clarification of fruit Juice & beverages
Clarification of sugar products
Bacteria removal filtration of fermentation broth
Colors, salt removal and concentration of dyestuff, etc
