Handling & Storage
To ensure proper handling of AQUADYN
®
FZ50 hollow fiber modules, please refer to the safety and handling instructions
below.
2.1
SAFETY INSTRUCTIONS
Having proper equipment is essential for safely executing the following handling instructions. Appropriate gloves, shoes and
safety glasses should be worn at all times. The following additional safety measures are recommended:
•
Be sure to read appropriate safety data sheets (SDS) before working with the chemicals.
•
The modules are shipped and stored in a preservative solution to prevent drying and reproduction of bacteria.
Please wear appropriate safety equipment when handling.
•
If preservative leaks from the module, avoid splashing. Use adequate protection to cover the module and any other
surrounding equipment.
•
If cleaning with a combination of acid and sodium hypochlorite, avoid mixing these chemicals as harmful chlorine
gas results.
•
Use a mask to prevent inhaling the gas from the preservative solution.
2.2
PRESERVATIVE SOLUTION
The module is shipped wet, in a preservative solution to prevent drying and bacteria growth. A solution of sodium
hypochlorite and water (10-20 mg/L free chlorine) or ~500 mg/L sodium benzoic acid water solution is used as preservative.
The module is filled with ~15 kg of preservative.
2.3
HANDLING
•
Avoid exposing the module with material that contains ester plasticizer or e.g. flexible polyvinyl chloride tube etc.
•
Avoid exposing the FZ50 modules to organic solvents, cleaning substances, fat, oil or adhesive tape, as these
materials may cause damage or cracks of the module.
•
Do not affix vinyl tape or packing tape to the module and avoid writing on the module with permanent marker.
•
To clean the outside of the module, use water and dry with normal cloth.
•
Please handle the modules with care. The module or hollow fibers may break due to heavy impact.
2.4
STORAGE
Avoid exposing the modules to UV rays and direct sunlight as the module casing and resin parts may deteriorate after being
exposed to UV rays or high temperatures for long periods of time. Modules should be stored in a place, out of direct sunlight
and UV rays and at a temperature between 5°C to
35°C (41°F to 95°F). Ensure that the module’s temperature doesn’t fall
below 5°C (41°F). If necessary, use thermal insulation around the body of the module.
The modules are packaged in a preservative solution to ensure that the hollow fibers inside the mo
dules don’t dry out. They
are also shipped with protective caps on the feed and permeate ports to protect the modules during storage and
transportation. These protective caps are not designed for use during operation, but to prevent the hollow fibers from drying
out and protection from bacterial contamination. If the original packaging has been opened, keep the outlets sealed.
Insufficient seals may cause the hollow fibers to dry out and and lead to poor module performance.
If storing modules that have been used, implement the disinfection procedure before storing it.
