At the end of the bar rack cleaning cycle the cleaning elements are positively cleaned by a pivoted comb which reliably discharges the removed screenings into a downstream transport or disposal unit. The easy to access and maintain drive unit is installed above the channel. Due to the screen’s compact design its height above floor is very low.
By developing the HUBER Multi-Rake Bar Screen RakeMax® CF, we have successfully united two proven screen designs into an innovative screening system that is unique in terms of both reliability and functionality. Due to its different design options the RakeMax® CF covers a very wide range of applications, allowing us to respond to the individual needs of our customers and to specific constructional and hydraulic site conditions.
The main benefits of the HUBER Multi-Rake Bar Screen RakeMax® CF at a glance:
- Proven technology of two screen designs combined into one
- High hydraulic throughput capacity due to U-shaped bar rack
- No submerged moving parts
- Very little space required due to vertical installation - ideal for narrow spaces and deep channels
- Rake tines fully engaging with the bar rack
- Screen rake engaging above the bar rack / water surface
- Increased separation efficiency through flow deflection in the bar rack
- An optionally integrable emergency overflow eliminates the need for an emergency bypass construction
This new development maintains the positive characteristics of the proven HUBER Multi-Rake Bar Screen RakeMax®, such as high screenings discharge capacity due to a variable number of rake tines, automatic scraper device without use of process water, etc.
The HUBER Multi-Rake Bar Screen RakeMax® CF has successfully proven its functionality in daily operation over a long time in a size 5 wastewater treatment plant. Due to positive experiences in practical operation it was possible to create and implement another innovation in the field of mechanical wastewater treatment.
Especially with existing screening plants the minimum requirements on solids retention in the inlet are often not reliably met. One reason for this is certainly that people can select from a great variety of sanitary products today and have changed their consumer behaviour during the past years. To meet these changed requirements the passage opening at the bar rack needs to be reduced.
This is usually accompanied by a growing hydraulic load. These conditions inevitably mean that a larger hydraulic passage area must be made available. This in turn usually means that the existing screen channel needs to be widened or even a new screen house must be built, with the consequence of high construction costs.
For such cases, HUBER offers with the HUBER Multi-Rake Bar Screen RakeMax® CF another screen option for headworks. RakeMax® CF screens can be adjusted to suit specific site requirements, both structural and hydraulic, and reduce investment and operating costs.
