Effective and reliable solution for both large and small sewage treatment systems.

Applications

The ICABUS is ideal for filtering sewage in urban areas, where the concentration of paper fibers is often high. The system offers a cost-effective solution to improve sewage quality without the need for expensive or complex filtration systems. It is the perfect choice for reliable and sustainable water treatment.

No blockages due to grease or pollution
The unique design of the ICABUS prevents blockages caused by organic matter or grease. This ensures that the system continues to operate smoothly without operator intervention.

Cake filtration
The ICABUS uses the principle of cake filtration, by which the contamination on the sieve (the cake) determines which particles are separated. As the brushes clean the sieve, the contamination is removed and a laminar water flow is created. This causes the fibers to be stretched out as they move along the sieve plate, effectively building up the cake. This natural separation mechanism ensures excellent filtration without clogging.

Installation
Thanks to its modular design, the ICABUS is easy to install, whether as a plug-and-play system in a container or built into existing infrastructure. This offers flexibility in application and installation to suit the specific needs of your water treatment plant.

Savings
Highly robust and low maintenance
Thanks to its robust design and self-cleaning method of operation, the ICABUS requires minimal maintenance and has low management and maintenance costs. This makes the ICABUS a sustainable choice with low investment and operational costs.

Energy efficient
The ICABUS consumes only 250 Watt of energy for a capacity of 700 to 1000 m³ per hour, making the system particularly energy efficient. The low speed transfers considerable power, allowing the motor to propel the brush holders effectively. In addition, there is a 1.5 kW pump for pulp discharge. By comparison, a belt sieve (max 400 m³/hour) requires 15 kW of compressed air to stay clean. So the energy consumption is 250/1000 versus 15,000/400. You do the math!

Cost-saving
The ICABUS offers significant savings compared to other fine-sieving systems. The payback period is only 3 to 4 years when using an existing digester, or 6 to 8 years for a new digester.

Sustainability

Digestion and biogas production
The pulp resulting from the sieving process can be digested to produce biogas (40% more biogas than surplus [SG2] sludge alone), or used as a carbon source for phosphate and nitrogen removal.

Contribution to circular economy
The harvested toilet paper fibers can be reused to make new sustainable products, closing the value chain and contributing to a circular economy.

Improved water purification
The ICABUS reduces undissolved particles in sewage by 30%, which increases sludge activity and contributes to the effectiveness of phosphate and nitrogen removal. The system also reduces aeration energy requirements by 14% and reduces surplus sludge by 20%.

CO₂ reduction
The ICABUS contributes to a reduction of approximately 1,300 kilograms of CO₂ per ton of sieved material, which also makes the system an environmentally friendly choice.

Maintenance

We drop by every few months for an inspection (adjusting the brushes if needed) but even if we didn’t, the system would simply keep running. The ‘wear-and-tear parts’ are PBT brushes that glide gently over smooth stainless steel plates. In other brush sieves, these brushes last for years. Even if the sieve plates or shaft bearings need to be replaced, the system is up and running again in a few hours. Every 5 years we like to have the system completely empty for an entire day so we can do a detailed inspection and replace some parts preventively.
