High-pressure Loose Reverse Osmosis membrane

SL Lithium RO 8040 HR 40
SL Lithium RO 8040 HR 40 High-pressure Loose Reverse Osmosis Membranes have relatively larger pore sizes, compared to traditional tight reverse osmosis membranes. It ranges from a few nanometers to several tens of nanometers, this allows certain larger molecular weight substances, such as some organic compounds and low molecular weight salts, to partially pass through the membrane, while traditional reverse osmosis membranes primarily retain almost all ions, small molecules, and large molecular solutes. Due to their structure and characteristics, High-pressure Loose Reverse Osmosis Membranes generally have higher water flux under the same operating conditions compared to traditional reverse osmosis membranes. This means they can process more water per unit time, enhancing water treatment efficiency. The main applications of the product are in areas where the stringent desalination is not required, but there is a need to separate specific solutes from water or concentrate certain substances to some extent.

Note:

1. If the temperature is higher than 95°F (35°C), please contact us to determine the specific solution.

2. The highest operating temperature is 95°F (35℃) when pH value is higher than 10.

3. Under certain circumstances, free chlorine and other oxidizing agents can cause premature failure of membranes, therefore, it is recommended to remove free chlorine before it contacts with membranes.

  • Preparations

    When the membrane system is ready to be commissioned, the membrane treatment system needs to be started up correctly to prevent damages to membrane elements caused by the overflow of feeding water and the hydraulic shock. The correct initiating sequence helps to ensure that the system’s operating parameters align with design requirements, so that the quality and quantity of produced water through the system reach designed objectives.

    Before the membrane system is initiated for the first time, pretreatment system debugging, elements loading, instrumentation debugging and calibration and ancillary equipment system debugging and so on shall be completed.

    Please contact us for more information.

  • Operation Guide

    During start-up, shutdown, cleaning, etc., to prevent potential damaged to membranes, any sudden changes of pressures or of crossflow flow in membrane elements shall be avoided. During start-up, it is suggested to follow the undermentioned procedures to gradually transit the system from shutdown to operating:

    Feeding pressure should be gradually escalated over a period of 30 ~ 90 seconds.

    The set peak of crossflow velocity should be gradually achieved over a period of 30~ 60 seconds.

    For more information, please contact us

  • Maintenance

    Once the membrane element is moisturized, it should always be kept moist.

    If users failed to strictly follow the set operating limitations, the warranty will be null.

    If the system need to be shut down for an extended period of time, it is recommended to immerse the membrane elements in protective solution to prevent microorganisms.

    The user shall be responsible for any damages to the membrane elements caused by using incompatible chemicals, lubricants, etc.

    The maximum pressure drop a single pressure vessel can tolerate is 50psi (3.4bar).

    Under all circumstances, backpressure must be avoided on the production side of the membrane system.
