Compact 33

The Compact 33 is a tubular 5.2 mm ultrafiltration membrane very well suited for the separation of biological sludge or any other high solids application in which high effluent quality is required. Separating at 0,03 micron, this membrane filter allows only water and dissolved matter to pass, rejecting everything that is undissolved. The filtrate can either be used directly in many applications, or be fed into another (RO) treatment system to remove the dissolved matter.

General Solvent Resistance

Since the resistance of the membrane to solvents strongly depends on the actual process conditions, the indications given below should only be considered as guidelines

Sodium Hypochlorite

Typical 200 ppm, at ≤ 40 ºC
Maximum 500 ppm
250.000 ppm hours cumulative at 30 ºC

*To avoid mechanical damage, do not subject the membrane module or element to sudden temperature changes, particularly decreasings. Do not exceed 60 °C process temperature. Bring the module or element back to ambient operating temperature slowly (typical value 3°C/min). Failure to adhere to this guideline can result in irreparable damage

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 coinditions after transfer of ownership for X-Flow BV 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.

X-FLOW COMPACT 33 HELIX - ULTRAFILTRATION MEMBRANE To avoid biological growth during shutdowns or storage, wet membranes should be treated with a compatible biocide. The membrane is compatible with many common disinfecting agents or biocidal preservatives. For short-term shutdowns, a daily flush with permeate quality water containing up to 2.0 ppm free available chlorine for 30 to 60 minutes may be adequate for bacteria control. In case of long-term storage, membranes should be cleaned before the disinfection step is carried out.

For disinfection, a 0.5% sodium metabisulfite solution can be used. In either situation, modules should be stored hydraulically filled. 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.
