Dr. Albert Heindl of wastewater treatment specialists HUBER Technology is among the line-up of confirmed expert speakers at SludgeTech 2017, the International Water Association’s upcoming specialist conference on sludge management at Imperial College London from the 9th–13th July.

The HUBER expert will be presenting at a workshop on the application of drying and advanced thermal conversion technology, one of a number of workshop sessions taking place at the conference.

The conference will bring together leading experts to share knowledge and insight into the challenges and opportunities surrounding sewage sludge and showcase the latest research and innovation.  

High energy and nutrient content mean sewage sludge is now regarded as a major opportunity for significant value recovery and revenues.In addition to energy generation, there is also considerable potential for the recovery of other biorenewable materials and industrial chemicals.

Backed up by extensive experience over the past 25 years in the UK wastewater treatment industry, HUBER Technology is flagging up the importance of matching the correct sludge product to the specific application.

Proven technology with a successful track record at 950 + UK wastewater treatment works

HUBER’s large and innovative product range is already in use at over 950 wastewater treatment works across the UK, including products at every stage of the sludge treatment process:

• Sludge Screening
• Sludge Thickening
• Sludge Dewatering
• Sludge Drying

HUBER also has a range of sludge dewatering trial plants available for customers to trial on their process streams. This includes a containerised unit with a HUBER Screw Press Q-PRESS®, polymer preparation equipment, feed pump, dosing pump and controls to enable full scale trials to take place.

Sludge Screening

HUBER Technology’s Sludge Acceptance Plant ROTAMAT® Ro3 is the perfect unit for tankered sludge coarse screening with a throughput capacity of up to 320m3/hr (dependant on dry solids content) The ROTAMAT® Ro3 is manufactured from stainless steel which minimises corrosion and ensures the unit is very robust. The Ro3 is already in use at 450+ UK reference sites.

For fine screening of sludge HUBER Technology have the HUBER Sludgecleaner STRAINPRESS® unit. This product is suitable for indigenous sludges or sludges that have normally been pre-screened. The sludge is screened up to 5mm in 2D, with finer meshes available and is dewatered to 35-45% DS. Both of the above screens incorporate screening, screenings washing (Ro3) and dewatering in one containerised unit using one single drive. HUBER have 350+ UK reference sites.

Key benefits of HUBER Sludge Screening are:

• High solids removal
• Low energy consumption
• Simple robust design
• Fully automated operation
• Containerised unit reducing odour

Sludge Thickening

Sludge Thickening is required to reduce storage volume on site, if the site is too small for dewatering to be viable then reducing the volume of sludge will reduce the transport costs.

The HUBER Disc Thickener S-DISC is suitable for smaller satellite sites. It is an inclined enclosed unit with a feed capacity up to 40 m3/hr and is available in 2 sizes with a compact footprint.

The HUBER Rotary Screw Thickener S-DRUM has a feed capacity up to 110m3/hr and is available in 2 sizes. Its unique design offers better process robustness and durability than a gravity belt thickener.

The HUBER Belt Thickener DrainBelt has a feed capacity up to 80m3/hr and is available in 3 sizes. The two smaller sizes achieve the same throughput as the HUBER Disc Thickener S-DISC. It has a low polymer consumption and minimum operating costs.

Key Benefits of HUBER Sludge Thickening are:

• Low energy & polymer Consumption
• Easy setup & low operator attendance
• Installed inside and outside
• Unique design & compact footprint
• Simple robust design
• Offsite build packages available
• Proven technology in use at 45+ UK reference sites

Sludge Dewatering

Sludge dewatering helps achieve a dryer cake for reduced transportation and storage costs.

The HUBER Screw Press Q-PRESS® is available in 4 sizes and is suitable for smaller sites. It has a variable throughput of 1-27m3/hr (depending on sludge type and input DS%) and achieves a high dewatering performance.

For Sludge dewatering the HUBER Screw Press S-PRESS can process a variable throughput up to 10-12m3/hr with a single unit.

Key Benefits of Sludge Dewatering are:

• Low polymer requirements
• Efficient and reliable operation
• Low power consumption
• Minimum operator attendance
• Offsite build package available
• Trial plant available
• Proven technology in use at 50+ UK reference sites

Sludge Drying

Thermal Sludge Drying will help to achieve >90% dry solids for reduced handling, storage and disposal costs. The HUBER Belt Dryer BT, which has been installed worldwide- including the UK, uses an innovative sludge pelletising technology and heat re-circulation, providing excellent product quality and reliability.

Key benefits of Sludge Drying are:

• Reuse of sludge for fuel / fertilizer
• Reduces costs or transport & storage
• Reduced odour during storage
• Low energy requirements
• Fully automated operation
