The key operational, energy and cost benefits of Huber Technology’s innovative RoS3Q Disc Thickener and RoS3Q Screw Press Dewater technologies are seeing an increasing level of interest and uptake across the UK water and wastewater sector.
Both technologies offer a range of key benefits to the utilities.
RoS2S Disc Thickener
At a recent Thames Water Innovation Day, Richard Willis explained that the RoS2S sludge disc thickener is the ideal solution to reduce tankering costs on small sites.
At the centre of the RoS2S is an inclined, slowly rotating filter disc that separates flocculated sludge from filtrate. The filter disc consists of a fine mesh cover (with roughly square apertures of 0.35 – 0.40 mm across) fixed on top of a rigid perforated carrier disc (with 5 mm dia. holes.) A baffle plate distributes the inflow from the flocculation reactor evenly across the entire filter radius.
Flexibly supported ploughs divide and move the sludge layer on the disc and open up furrows so that water can easily drain through the filter mesh, thus enhancing the filtration effect. As the filter disc continuously rotates, a scraper pushes the thickened sludge from the disc. The filter mesh is backwashed with a spray bar.
Key benefits of the Disc Thickener include:
- Low operation costs as a result of excellent performance and easy system operation:
- Unique design
- Very small footprint
- 2 sizes available for up to 40m3/hr of throughput
- Low polymer consumption
- Fully enclosed design
- Filtrate water can be utilised to wash the disc
- Capture rate of 97-99%
- Low power consumption
- Primary, Secondary sludges
- Digested sludge
- Flotated sludge
- Membrane sludge
- Conical auger shaft
- Three wedge wire sections with different bar spacings
- Continuous wedge wire inside, cleaned by a wiper mounted on auger flights
- Pressurised feed (0-500mbar)
- Pressure monitoring / control
- Totally enclosed with easy access through large inspection openings
RoS3Q Screw Press Dewaterer
The RoS3Q is a screw press with a conical screw shaft and cylindrical sieves consisting of three treatment zones: inlet and drive zone, three-part thickening and dewatering zone, and press zone with pneumatic counter – pressure cone.
The innovative RoS3Q is ideal for dewatering the following types of sludges:
- Primary, Secondary sludges
- Digested sludge
- Flotated sludge
- Membrane sludge
Key features of the RoS3Q include:
- Conical auger shaft
- Three wedge wire sections with different bar spacings
- Continuous wedge wire inside, cleaned by a wiper mounted on auger flights
- Pressurised feed (0-500mbar)
- Pressure monitoring / control
- Totally enclosed with easy access through large inspection openings
Outstanding energy efficiency and a low operator attention requirement are among the key benefits for end-users. The compact, space saving, stainless steel design, together with vibration free, virtually noiseless operation and minimum costs for wear parts mean the RoS3Q is increasingly the technology of choice for utilities who want maximum operational efficiency and cost benefits throughout the de-watering process.
