Filtration is used in various industries to remove impurities from wastewater and process water. The HUBER Disc Filter RoDisc is frequently utilized for the separation of fine suspended material from biologically treated wastewater.

In municipal and industrial applications, the RoDisc reliably achieves effluent values that are significantly better than the required limit values for filterable solids. This is especially true when secondary clarifiers are too small or the settling behaviour of the activated sludge is poor.

The RoDisc is also used for the removal of microplastics from wastewater. This is a significant issue in the plastic processing industries, where microplastics can contaminate the environment.

Here are some typical fields of application for the use of disc filtration:

In addition to these applications, the RoDisc is also used for the treatment of service and process water, closing water loops in industries such as food and chemical.

The filtration process of a disc filter is quite impressive, and it all starts with the grooved, compressed plastic disc rings. These rings produce a deep filtration process as dirty water is pumped in and pressure increases on the outside, compressing the rings tightly.

The grooves in the disc rings crisscross, forming a three-dimensional network that traps particles. This design filters the dirty water thoroughly, not only on the outer surface but through the entire depth of every ring's grooves.

The result is a larger, more efficient filtering area compared to screen filters, with more debris being captured and cleaner water exiting from the filter. This process is particularly effective in removing filterable solids after secondary treatment in wastewater treatment plants.

The Filtration Process is a crucial step in ensuring clean water is produced. The process involves three main stages: the filtering process, self-cleaning filtration stage, and backflushing stage.

The filtering process starts with grooved, compressed plastic disc rings that produce a deep filtration process. This is achieved by compressing the rings together tightly as dirty water is pumped in, creating a three-dimensional network that traps particles.

The number of crisscrossed intersection points on each groove varies depending on filtration grade, creating an environment where particles are eventually trapped. This design filters the dirty water thoroughly, not only on the outer surface but through the entire depth of every ring's grooves.

Water then flows from the outside of the disc stack to the inside, passing along the specially designed grooves on the surface of the disk filters which catch suspended material. This is the self-cleaning filtration stage.

The Vortix generates an outward centrifugal helical effect upon entry into the filter, moving the particles away from the disks. Clean filtered water then passes efficiently through the depth of uniquely designed discs.

In the backflushing stage, clean water from the auxiliary filter is introduced from the reverse direction through the filtering element. This decompresses the stack discs, allowing them to separate and back-wash efficiently.

The solids are expelled from the discs and exit through the back wash manifold. The filtration process then restarts with the compression of the discs.

The Vortix generates an outward centrifugal helical effect upon entry into the filter, moving particles away from the disks. This helps to prevent clogging and ensures efficient filtration.

Clean filtered water then passes efficiently through the depth of uniquely designed discs. This is made possible by the self-cleaning technology.

The screen surfaces are cleaned by a spray nozzle bar, which extracts the required water directly from the filtrate. Chemical cleaning may also be necessary from time to time to remove biofouling or inorganic residues.

In fact, the Vortix system is designed to handle a wide range of flow rates and configurations, making it suitable for various industries and applications.

Here are some examples of industries and applications where the Vortix system can be used:

Disc filters offer a unique disc filter design, engineered for longevity and low maintenance. They reduce the overall cost of ownership with features such as filtration degree from 5 to 400 micron.

The disc filter is a self-cleaning system that works without any interruptions. It automatically flushes by means of both differential pressure and time. This means you don't have to worry about manual cleaning, saving you time and effort.

Highly durable with corrosion-free plastic construction materials, disc filters are designed to withstand harsh conditions. The working principle is a combination of surface, depth, and vortex/cyclone filtering, providing efficient filtration performance.

A centrifugal action optimizes filtration performance and reduces backwash frequency and maintenance. The self-cleaning filtering element uses minimal water for an efficient cleaning action. This is especially useful in water-saving systems.

Disc filters come in a range of flows and configurations using a minimal number of components. They're compact and assembled for easy transportation and installation, often referred to as 'plug and play'. This makes them a cost-effective solution for various applications.
