Sludge treatment equipment are designed and engineered to serve different functions and requirements of sludge treatment. Some of the important functions of sludge treatment equipment include -
- Mixing of municipal industrial wastes, deep tank blending of high viscosity fluids, de-icing applications.
- Filtration of industrial liquid.
- Handling of concentrated municipal and industrial sludges, dewatering and lifting devices for heavy solid uses and applications.
- To remove water from the liquid wastewater residues and to form a non-liquid material.
- Sludge flotation
- Anaerobic digestion for the volume and mass reduction of input material.
Sludge treatment is a critical issue, which affects both the environment and the economic stability of various treatment sectors. It is a problem, which brings various factors into play – the quantities produced, the treatment processes involved and the various reprocessing sectors involved (energy and biological). A major factor that contributes to the increasing demand for sludge treatment equipment is extensive population growth. With increasing population, the sludge generation volumes are continuing to rise, thereby pushing the manufacturers to seek further solutions for sludge treatment.
According to a report, dewatering equipment and thickening equipment, jointly account for about 68% of total sales of sludge treatment equipment. Municipalities are the main source of revenues for the sludge treatment equipment market accounting for about 76%, while the pulp & paper and the food & beverages dominate the industrial applications in the sludge treatment industry. However, the present industry regulations and public demands are affecting both the municipalities as well as industrial end users. Trends suggest that in future, industrial end users will It has also been observed that in the future, industrial end users will grow in importance, as the awareness on the benefits of using the sludge treatment equipment for sludge processing is compounding with the attempts to conform regulations as well as to gain cost efficiency by recycling wastewater.
The techniques for sludge treatment and disposal have been subject to rigorous testing and inspection, which is due to the strict policies governing the treatment processes suitable for final disposal routes. The regulatory factors act as dominant forces and present an important market opportunity for equipment manufacturers. The urban wastewater treatment directives drive the market to meet legislative requirements, thereby boosting the demand for treatment equipment. However there is a need for superior technology capability and knowledge of industry.
Flexible and innovative services are also expected to ensure future growth in the regulated market of sludge treatment wherein the environmental consciousness in rising. Considerable opportunities remain in upstream efficiencies adaptability and innovation is a key for success. The most progressive technologies, like drying and dewatering, continue to be beneficial to companies compelled to look for methods to reduce the amount of water content in sludge in order to minimize the transportation and disposal costs. Sludge drying is expected to earn huge demand and revenues with continuously increasing safety regulations and restrictions being placed on disposal alternatives such as landfills.
