General Information

Membrane Characteristics

• Hydrophilic membrane composed of a blend of modified polyethersulfone and polyethersulfone
• Structure asymmetric/microporous
• MWCO of 10 kDa on dextranes
• High performance and a very good anti fouling behaviour
• Typical permeate quality SDI<3, turbidity <0,1 NTU
• Designed for silica retention; typical > 99.8% for colloidal silica (tested on surface water containing 10 mg/l total silica and 1 mg/l colloidal silica)

Operating Specifications

* In case of horizontal dead-end configuration or vertical dead-end pressurized configuration: max. system pressure, see specifications of membrane housing supplier (Codeline or equivalent).

• Backwash water should be free of particulates and should be of permeate quality or better.
• Backwash pumps should preferably be made of non-corroding materials, e.g., plastic or stainless steel. If compressed air is used to pressurize the backwash water, do not allow a two-phase air/water mixture to enter the element.
• To avoid mechanical damage, do not subject the membrane module or element to sudden temperature changes, particularly decreasings. Bring the module or element back to ambient operating temperature slowly (max. value 3 °C/min). Failure to adhere to this guideline can result in irreparable damage.

Operation of membrane modules at any combination of maximum limits of pH, concentration, pressure or temperature, during cleaning or production, will influence the membrane lifetime.

Storage

New membrane modules can be stored as supplied in the original packaging. The membrane elements contain an aqueous preservation solution of glycerine (20wt%) and sodium metabisulfite (1wt%).

Membrane modules should be stored in a dry, normally ventilated place, away from sources of heat, ignition and direct sunlight. Store between 0 and 40 °C.

The membrane modules should not be subjected to any freezing temperatures.

Shelf life is a maximum of 6 months for unused modules in unopened packaging under correct storage conditions after transfer of ownership for X-Flow B.V. to the Client. After the maximum period of 6 months all warrantees are null and void unless otherwise agreed in writing between the parties.

After use, the UF membrane modules need to be stored wet at all times.To avoid biological growth during shutdowns or storage, wet membranes could be treated with a compatible biocide. The membrane is compatible with many common disinfecting agents or biocidal preservatives. 

Typically for short-term shutdowns (1 – 7 days), a daily backwash with UF permeate quality water for 30 seconds at 215 lmh, should be adequate for bacteria control. Before start of the shutdown period, the modules must be cleaned by a standard Chemical Enhanced Backwash (CEB).

In case of long-term storage (> 7 days), membranes should be disinfected. The membranes should be cleaned using a CEB before the disinfection step is carried out. For disinfection, a 0,5% sodium metabisulfite solution can be used. In both short and long term storage situations, the modules should remain filled with storage solution.
