JIUWU Tubular inorganic ultrafiltration ceramic membrane filters

JIUWU ceramic membrane element has an asymmetrical structure consisting of three layers, which are filtering layer, intermediate layer, and support layer. The pressure drop of such asymmetrical structure is lower than that of symmetrical structure of other membrane, which means that ceramic membrane element has better recovery. 

1.      What are the advantages of Ceramic Membrane?

Compared with such traditional filter like polymer membrane, ceramic membrane has many unique advantages:

v  High separate accuracy, limpid and transparent filtrate with little content of impurity;

v  Pure aluminium oxide brings membrane excellent performance on resistance to acid and alkali and makes the membrane longer working life;

v  No additive needed, the dense bacterial residue can be recycled as feed, so it’s an environmental friendly technology;

v  Operate under normal temperature and obturation, which ensure product activity. More of the original flavour and aroma of the fruit is retained;

v  Higher yield rate of high quality products;

v  The membrane pore size keeps asymmetric distribution and low slow decay, and maintain high flux filtration;

v  Greatly reduce the discharge of waste;

v  Membrane runs with high strength and excellent wear resistance

v  Controlled by PLC automatically

v  Less grounding necessary for installation &small footprint

2.      How does ceramic membrane work?

During filtration by means of ceramic membrane made by JIUWU the medium to be filtered flows through the channels of the membrane carrier. All particles whose size exceeds the pore radius of the membrane are retained. The particles /molecules build up in the concentrate. The filtrate permeates through the pores and depending on the procedure is subjected to subsequent process stages. This filtering method is also called “cross-flow filtration” or “dynamic filtration” . Cross-flow management can achieve stable fluxes. Cleaning is performed by means of backward flushing or chemical cleaning.

3.      Does ceramic membrane need to be cleaned?

Membrane fouling is a major obstacle to wide spread application of the membrane. It is the phenomenon whereby the membrane permeated flux decreases and the transmembrane pressure (TMP) rise with the passage of time due to the membrane fouling. To solve the problem, cleaning step is must be took, or the membrane after using can be exchanged.
