VONTRON  ZERO-FR10 ZERO Liquid Discharge（ZLD）- ZERO series.

Product Presentation:

ZERO-FR10 element is one of the industry’s most advanced fouling resistant element technology special designed for high TDS level 5000-15000 ppm, and high COD wastewater reclaiming in zero liquid discharge process. Base on the new generation of membrane separation layer technology and unique component structure, It is a low pressure drop, long cleaning cycle, high chemical cleaning resistance membrane element product.

Application:

Reuse of High Salt and High COD Wastewater.

Primary Concentration and Reduction Stage of Zero Liquid Discharge Technology

Suitable for TDS 5-15g/L of Feed Water.

Important information:

Before the  membrane  element  leaves  the  factory, The  dry  membrane  element  has  no preservation solution, The wet membrane element has 1.0% sodium bisulfite (in winter, add 10% of  propylene glycol antifreeze)  as the  preservation solution for storage treatment and  use vacuum packaging.

Dry  membrane  elements  should  always  be  maintained  wet  after  Soaking;  when  wet membrane elements are not used for a long time, preservation solution is needed to soak the elements.

When the membrane element is used for the first time, it is recommended to flush it first for15-25 minutes at low pressure (not suitable for soaking or soaking overnight), and then flush it for 60-90 minutes at high pressure (the water flow should not be less than 50% of the system design water flow).

The permeate water and concentrated water within the first hour of the initial operation of the membrane element should all be discharged.

The operating limits and operational guidelines given in this technical information are part of the limitations of the three-year warranty on the membrane element.

The addition of any chemicals that may affect the membrane element during storage and operation  is  prohibited,  and Vontron Technology will  not  be  liable  for  any  consequences arising from the use of such chemicals.

Please refer to the Product Manual for details on installation, commissioning, storage, and transportation of membrane elements.
