Page 4: Introduction
Introduction MANN+HUMMEL Water & Fluid Solutions (WFS) offers a wide variety of capillary modules under the MICRODYN brand. MICRODYN cross-flow microfiltration (MF) modules are used to separate suspended solids larger than 0.2 micron. The highly porous polypropylene (PP) membrane is backwashable, allowing for stable and efficient filtration with continuously high product flux. -
Page 5: Product Description
Please refer to Appendix 1, Table 1 for an overview of available MICRODYN capillary modules. For more module-specific data, please refer to the respective datasheet on the webpage (Capillary & Tubular Modules - MANN+HUMMEL Water & Fluid Solutions (microdyn-nadir.com) MICRODYN CAPILLARY MODULES | USER MANUAL MANN+HUMMEL Water & Fluid Solutions | REVISION DATE: 09/09/2021... -
Page 6: Shipping, Handling & Storage
All new modules being stored prior to use should remain in original packaging. RETURNING A MODULE If a module is returned for any reason, MANN+HUMMEL WFS must approve the shipment first. Please contact the appropriate MANN+HUMMEL WFS representative before sending the product back. Non-approved return shipments will be rejected. -
Page 7: Installation & Activation
In the vertical position, the permeate outlet must always be toward the top of the module so that air can be removed completely from the module prior to operation (Figure 3).

Page 8: Activation With Water Pressure
In the PBP process, a part of the permeate is pushed back by compressed gas (e.g. air). Care must be taken so that the gas is not pressed into the membrane. Otherwise, the membranes will be made a partially hydrophobic with reduced flux. A reactivation must then be performed.

Page 19: Chemical Cleaning
Inorganic fouling (e.g. mineral salts, ferrous compounds) is removed using acidic agents. Organic acids like citric acid, oxalic acid, or mixtures of hydrochloric acid and oxalic acid have proven favorable. • For more information about cleaning, please consult MANN+HUMMEL WFS.

Page 20: Piloting
Pilot testing is usually required to determine the feasibility and process parameters of the filtration/concentration process utilizing MICRODYN. Please note that MANN+HUMMEL WFS offers compact pilot units (see Figure 17) and supervision of piloting. For more details, please contact your MANN+HUMMEL WFS representative. -
