Biological filter 2-chamber 1,5 m³ for CWS and ponds

Effective biofiltration of water for aquariums and fish farming

The 2-chamber 1.5 m³ biological filter is a reliable solution for water treatment in closed water supply systems (CWS), ponds and aqua farms. It is designed to decompose ammonia and nitrite, providing stable water parameters and creating optimal conditions for growing fish, shrimps and crayfish.

Key advantages of the CrawTec 1.5 m³ model

1. Dual chamber filtration system. Splitting the water flow into two chambers increases the efficiency of cleaning and allows you to achieve a stable operation of the filter.
2. The volume of bio-loading - 1000 litres. The filter can be equipped with 500 litres of floating loading and 500 litres of tinting, which provides a huge working surface - 1000 m²/m³.
3. Robust housing. The filter is made of 10 mm thick food-grade polypropylene, resistant to water, chemical attack and mechanical damage.
4. Optimum water exchange. Three inlet and three outlet connections (Ø110 mm) allow even distribution of the load and adaptation of the system to different water volumes.
5. Efficient aeration. Includes 3 340 mm diameter disc atomisers and a compressor to maintain high oxygen levels in the bio-load.
6. Easy maintenance. The filter requires no complicated maintenance, is easy to rinse and will not clog if used correctly.

How does a 2-chamber biofilter work?

The first chamber retains mechanical particles, reduces water turbidity and evenly distributes the flow.
In the second chamber, biological purification takes place - beneficial bacteria decompose ammonia and nitrite, turning them into safe nitrates.
Built-in atomisers saturate the water with oxygen, which accelerates the biofiltration process.

Where can this filter be used?

• In closed water supply systems (CWS) - maintains stable water parameters.
• In fish farms - improves water quality in pools and tanks.
• In ornamental ponds - prevents water colouring and removes impurities.
• Aquafarms - ideal for fish, crayfish and shrimp farming.
