[...]Using the energy of the sun Solar drying of sludge uses the energy of the sun as a thermal energy source. This provides a very ecological, environmentally friendly and energy-efficient process for the treatment of sludge from wastewater treatment plants or water purification plants. The basic principle of the process is that the sludge is dried in a greenhouse structure. The sludge can be brought into the greenhouse manually, for example with a wheel loader, or automatically directly from the dewatering facility by means of special conveying units. In the greenhouse, the sludge must be distributed[...]

[...]Efficient drying process for partial drying of sludge The HUBER Disc Dryer RotaDry® is used for the disc drying process. A disc dryer is a contact dryer that transfers heat to the medium to be dried via direct contact of the hot disc. HUBER is an expert in drying processes and designs the optimal drying plant based on the individual requirements to ensure an economically and ecologically optimal utilisation of the sewage sludge. Disc Drying of Sludge The entire disc dryer process consists of the following main components and process steps: Intermediate storage and feeding To ensure continuous[...]

[...]From the screenings wash press to the container – reliable conveyor technology for any requirement After the screenings have been washed and dewatered in the HUBER Wash Press WAP® , they have to be discharged into the collection container. Depending on the amount of screenings and the local conditions, this transport operation can be simple or very complex. In the simplest case, the HUBER Wash Press WAP® discharges the screenings directly into a container standing next to the wash press. However, as soon as longer distances have to be covered and/or the screenings have to be transported from[...]

[...]Identification of the ideal time for screw shaft maintenance Maintenance of the HUBER Wash Press WAP® as and when required Sensor with signal LED on the HUBER Wash Press WAP® Also for retrofitting to the HUBER Wash Press WAP® The aim of the HUBER Wash Press wear detection system is to enable a preventive maintenance strategy. The system detects a threshold value in the diameter loss of the compacting screw in the closed compaction zone section of the wash press. This part of the compacting screw is usually the machine component subject to the most wear. At the same time, however, it is difficult [...]

[...]HUBER Detection System Safety Vision Innovative digitalisation module for the HUBER Multi-Rake Bar Screen RakeMax® Maximum machine availability and operational safety through detection of critical material to protect the screen and downstream machines Reduced wear and maintenance, increased machine lifetime and reduced costs Screenings volume-dependent control of downstream machines Optimal machine utilisation through adaptive operation based on event detection Challenges and Prevention Challenges in mechanical preliminary wastewater treatment The main task of the screens used and installed[...]

[...]Replacing the primary clarifier with a fine screen – HUBER CarbonWin® In the HUBER CarbonWin® process, the primary clarifier is replaced by a fine screen. This results in the following advantages: Only 1/10 of the space required compared to conventional primary clarifiers Minimised investment and operating costs Suitable to be integrated into existing plants The primary clarifier is the last stage of the mechanical pre-treatment of a wastewater treatment plant and works according to the anaerobic sludge stabilisation process. In the primary settling tank, undissolved organic and inorganic substances[...]

[...]Tailor-made solutions for fish protection We develop solutions that are both designed and implemented to be sustainable and long-lasting. This starts with resource-saving manufacturing of our screens and screening machines, and continues with optimisation of structures for water abstraction projects, right through to comprehensive concepts for fish protection. Technical options HUBER solutions for fish protection Optimal fish protection starts with the correct design of the structure and the screen concept. This also includes fish deterrent systems and specially shaped filter elements for belt[...]

[...]Various solutions for conveying sewage sludge The heart of an economical sludge dewatering system is the HUBER Screw Press Q-PRESS® , which is in use in thousands of installations worldwide. However, the right solution for the subsequent transport of the dewatered sludge into the provided containers is also of great importance for the implementation of an optimal and practicable dewatering process. HUBER offers various solutions for container filling, which can be differentiated in terms of sludge volume or sewage treatment plant size, number of containers and degree of automation. Solutions [...]

[...]Safe working in manholes – safe opening and access Manholes fulfill an important task in water supply and wastewater disposal. They are used for example where shut-off fittings in pipelines must be accessible, or to control sections of very long pipelines, and for aeration/deaeration or access to complex installations (e.g. well shafts, pressure reduction shafts). Easy and safe access must be ensured in each individual application. Most of the manholes are entered from the top. This means that the operating personnel must open the manhole cover in order to then be able to use an entrance [...]

[...]All-round building protection with tested security We must eliminate the risk of any manipulation of our drinking water and its quality. Access to the free water surface must be prevented and the plants protected against vandalism and theft. The exterior shell of objects should therefore be designed as a mechanical barrier with a long resistance time. Criminal investigation departments recommend, among other measures, the use of security doors certified to resistance class RC3 or RC4 in compliance with DIN EN 1627. For vertical access, it is best to use tested security manholes covers . Certified[...]
