| - Due to the use of durable and chemically stable membrane materials (PES / PVDF), the MaxFlow membrane module has a high filtration performance with low fouling potential. By using low differential operating pressures, scaling is effectively prevented.
- The innovative MaxFlow module „open channel design“ provides optimal biofilm control and minimizes the quantity of chemical cleaning procedures. Multi-module arrangements guarantee extremely high energy efficiency plus a high packing density per square meter. This further reduces plant operating costs.
- The compact module design enables multi-stack module arrangements using shallow water levels. Therefore, a future plant upgrade to increase capacity is easy to implement.
- The MaxFlow membrane module is resistant to clogging due to its open-channel design. A simple screen or settling tank is sufficient as pre-treatment.
- The MaxFlow filtration modules can be cleaned inside the process tank using the „cleaning in place” (CIP) method. Depending on the wastewater source, cleaning intervals range between 2-6 months. The modules may also be cleaned outside the process tank if desired.
- The robust design and the safe, easy handling of MaxFlow membrane modules allow for simple plant layouts.
- Most existing conventional treatment plants can be retrofitted with Maxflow membranes due to the flexible and compact nature of our membrane module design.
