Dewatering Technologies: Ashbrook Simon-Hartley offers the most cost-effective and high performance sludge treatment solutions for every possible municipal and industrial application
The Aquabelt range of gravity belt thickeners are designed to take any kind of sludge and thicken to 3 to 5% dry solids. For further dewatering the Klampress range of belt filter presses can be relied on to produce a consistent 25%+ dry solids cake.
As the needs of industry and sewage treatment plants develop over time, with ever-changing processes and tightening regulations, so does the range of solutions offered. In addition to constant development of the core Aquabelt and Klampress ranges you will find many examples of the company's continued innovation in the product profiles provided here.
- Belt Filter Press
Robust design, quality engineering and high performance make the Klampress the industry standard for belt filter press technology. Compared with centrifuges they offer a host of financial and operational advantages:
- Low power consumption, typically 10% of a comparable throughput centrifuge
- Low polymer consumption
- Easy installation on a small footprint
- Low operating costs and no need for major overhauls
Since its creation the Klampress and Winklepress concepts have been continuously developed to meet, and frequently, exceed customers dewatering demands. In addition to the core range of two-belt models, recent introduction of the 3-belt Klampress and Europress ranges justify the claim that whatever the dewatering challenge there is always a Klampress to meet it.
Variable incline discharge ramp for achievement of very high cake dry solids output, which other makes struggle to match.
Proprietary polymer mixer for immediate and precise adjustment of polymer rate and clog free continuous operation.
Smartpress belt tensioning and alignment system which automatically accommodates variation in sludge feed to ensure consistent and continuous output to pre-set requirements.
With five models to choose from with a range of belt width and roller configurations there is a Klampress to match any application.
-Extended deck for very high throughput applications
-High pressure version for ultra high solids cake production
-Full enclosure for odour prevention
-Customised configurations engineered for unique applications.
3-Belt Klampress: By combining thickening and dewatering decks in one unit feed sludge only has to be mixed with polymer once, so polymer consumption can be halved. Installed on a footprint of half that required for separate belt thickening and de-watering the 3-Belt Klampress is also the most convenient solution where space is at a premium. The 3-Belt Klampress is specifically designed to take dilute sludge feeds (< 1.5% dry solids) and dewater right up to 25% dry solids in one process.
WINKLEPRESS Belt Filter Press Technology: After all of the tests are in, and the studies complete, the Winklepress stands alone as the clear winner in high-performance dewatering. The Ashbrook Simon-Hartley Winklepress combines advanced, high-durability engineering, precision workmanship and long-life materials into a single masterpiece of performance and value.
By maximizing gravitational forces, linear and shear pressure effects, and Ashbrook Simon-Hartley's proprietary engineering features-such as floating chicanes, dandy rollers and precision polymer mixers - the Winklepress is able to deliver throughput rates unequaled by other technologies. Other technologies typically have limited process flexibility, with little room for rheological variations in the influent. The Ashbrook Simon-Hartley Winklepress maximizes performance with multiple and distinct processing zones - taking advantage of numerous dewatering strategies - resulting in exponentially increased dry cake results.
- Belt Thickening
Ashbrook Simon-Hartley offers several thickening technologies covering the full range of sludge throughputs:
Aquabelt Technologies® - Provides solutions and flexibility for municipal and industrial applications while providing the most efficient means of thickening dilute process streams.
- The Aquabelt® STD
- Aquabelt® STD - Enclosed
- Aquabelt® COMPACT
- Aquabelt® COMPACT - Enclosed
- ABCT Aquabelt ® - gravity belt thickeners for throughputs from 15 to 150 m³/hr.
- DAB System - 'in vessel' thickeners for throughputs from 1.5 to 12.5 m³/hr.
All technologies have the flexibility to process SAS, primary or mixed sludge and take sludge feeds as thin as 0.5% ds. In typical applications DABs and Aquabelts are used to produce a thickened sludge of 3 to 6% ds but have the flexibility to thicken up to 7 to 8% ds where required.

Rugged stainless steel construction and automatic controls allow outdoor installation and unmanned operation. And with the minimum of moving parts it is highly dependable for long periods of maintenance-free operation. The DAB System opens up the possibility of thickening sludge on-site at remote or smaller STWs. It is a very low cost solution for local thickening that yields significant savings by dramatically reducing the volume of sludge transported away for centralised thickening.
-Low polymer consumption
-Stainless steel construction to allow outdoor installation
-Completely visible and easily adjustable process
With the new generation of ABCT Aquabelts 'spill free' operation is guaranteed by their new auto-sensing belt tensioning and alignment system. As you would expect the ABCT also includes the robust design and quality engineering that have made it the industry standard for sludge thickening:
Unique adjustable ramp allowing precise adjustment of thickened sludge dry solids content while operating
Proprietary polymer mixing for immediate and precise adjustment of polymer rate and clog free continuous operation
