1. What is the maximum flux of the membranes?      

The maximum flux through Motimo hollow fibre membranes depends on the type and concentration of the raw water. Pure water flow in a MOF 1616 module is between 6500 - 8000L/hour. When treating secondary clarified effluent the flow reduces to approximately 2000L/hr. The FP-1A MBR flat plat has a pure water flow of 5000L/hour. In domestic wastewater, the average flow reached is around 150L/hour.

 2. What are the guarantee details of the membranes?   Answer

3. What range of CMF, MBR and other types of membrane project do you have in operation ? Answer

4. What pollutants affect membranes most ?

In CMF systems, oils, particularly mineral oils, at too high concentrations can affect the membranes. Solids >0.5mm diameter should be removed form CMF feed water. MBR systems are less susceptible to fouling form oild, however limits are recommended for oils and solids diameters.

MF and UF membranes are also susceptible to some coagulating metal salts, such as iron and aluminium, and colloidal material. All pollutants should be reduced or removed from the water to be treated to avoid membrane damage or deterioration.

5. What is the minimum monitoring that should be carried out to ensure good system performance? Answer

6. What are the most common factors for failure of CMF/MBR systems? Answer

7. What membrane material do you use? What are the benefits / disadvantages? Answer
