Microfilters
Efficient Drum Filtration for Water Treatment and Fiber Recovery
The Algas microfilter is a high-performance drum filter with unique design features. Because it filters from the inside out, the recovery trough can be placed inside the drum. As a result, the filter operates at a higher level than conventional filters, which increases filtration time and improves efficiency.
Moreover, the Algas microfilter uses only atmospheric pressure. This means solids are not pushed or pulled into the filter medium. Therefore, the filtering action is gentle. Consequently, the clear filtrate contains only microscopic solids, making the water safe for reuse. In addition, the filter medium is easy to clean. Filter cloth types range from 10 micron for special tasks up to 1000 micron for thickening applications.
Algas microfilters are available in many sizes. However, the filter capacity depends on several factors, such as:
- Production type
- Water type and flow
- Fiber content and pH
- Temperature
- Required cleaning effect
- Content of fillers and other materials
Because of our experience in custom filter dimensioning, we can select the best microfilter solution based on data from similar installations.
Applications of Algas Microfilters include:
- River water treatment
- Fiber recovery – replacing fresh water with clear filtrate
- Improving “clear” water from save-alls, DAF units, and disc filters
- Treating filtrate from screw presses – saving water, fibers, and separating fines and fillers
- Separate treatment of DIP sludge
- Increasing capacity of existing effluent systems
- Treating black liquor
- Pre-thickening of bio sludge
- Microfiltration after final biological treatment for water reuse or discharge
In summary, the Algas microfilter ensures high-efficiency water filtration, sustainable water management, and better fiber recovery for the paper industry and other industrial processes. Therefore, it is a reliable choice for mills seeking efficiency and water savings.
Our Solution:
Algas microfilters provide a proven solution for fiber recovery and process water reuse in the pulp and paper industry. By efficiently separating usable fiber from white water, our systems deliver a high-quality filtrate that can be safely reused in production. This significantly reduces both heating energy consumption and overall water usage in your plant.
With over 30 years of experience and hundreds of successful installations worldwide, Algas has become a trusted partner in industrial water treatment and fiber recovery. Our flexible microfiltration technology adapts easily to a wide range of processes, supporting the growing need for sustainable water management across multiple industries.
Choose Algas microfilters to improve process efficiency, lower operating costs, and contribute to a more sustainable production environment.
Advantages:
- Water savings – efficient re-use of process water.
- Energy savings – re-use of warm clarified water instead of heating new fresh water.
- Raw material savings – filtration saves good fiber for re-use.
- Power savings – recovering the raw materials retains the power that has been put into processing it.
- Waste savings – reduced solids loading in the effluent plant reduces the handling of sludge.
- Chemical savings – chemicals are recovered in the raw materials and in the effluent plant.
