Sludge Treatment

Sludge, the residual byproduct of municipal and industrial wastewater treatment processes, carries the potential for significant harm if not managed in an appropriate manner. At Zirsakht Tadbir Arian (ZETA), we offer a range of sludge treatment methodologies aimed at waste reduction (both in terms of sludge weight and volume), cost reduction in disposal, adherence to environmental regulations, and mitigation of environmental harm.
The following processes are available within this section:


Anaerobic Digestion

Sludge digestion technology stands as an indispensable facet of wastewater treatment, harnessing the inherent capacities of microbial processes to degrade organic matter present in sewage sludge. Within the digestion process, microorganisms engage in the metabolic breakdown of the organic constituents contained within the sludge, resulting in the generation of biogas and the stabilization of solids. At Zirsakht Tadbir Arian (ZETA) Company, we excel in delivering anaerobic digestion processes characterized by remarkable efficiency and an elevated rate of biogas production.

Our expertise extends to the design and implementation of both thermophilic and mesophilic processes, tailored to meet the specific desired outcomes of the system. Moreover, we factor in considerations such as the input sludge volume and characteristics, prevailing site conditions, available space, and the adaptability of the existing wastewater treatment process—particularly in the context of fluctuating loads. This allows us to design either single digestion units or employ two-stage and batch digestion configurations as deemed most suitable for your unique requirements.

Our comprehensive capabilities encompass Engineering, Procurement, and Construction (EPC), ensuring the seamless execution of turnkey projects in this domain. Furthermore, we facilitate the acquisition of essential equipment, including digesters, and possess the means to convert biogas into a valuable energy source. We source such equipment exclusively from renowned and reputable manufacturers, assuring both reliability and performance in every facet of our offerings.


Thermal Hydrolysis Process

Thermal hydrolysis is a technological process effectively employed within wastewater treatment facilities during anaerobic digestion. As an optimized approach, it notably enhances the efficacy of anaerobic digestion processes while concurrently diminishing the volume of residual sludge and associated environmental pollution. Additionally, it contributes to the reduction of construction and operational expenses related to digestion tanks.

Within the thermal hydrolysis process, wastewater sludge or various other wet organic waste materials undergo exposure to elevated temperatures and pressures, thereby augmenting their digestibility. This versatile technique accommodates a broad spectrum of organic waste sources and residues, encompassing municipal wastewater treatment sludge, animal manure, and agricultural byproducts. It is harnessed for the production of high-quality biogas and organic fertilizers.

In summary, the application of this method affords the following merits:

Elevated biogas production rates.
Enhanced anaerobic digestion efficiency.
Improved sludge management and dewatering procedures.
Substantial reduction in the carbon footprint.
Production of high-quality biogas suitable as a renewable fuel source.
Generation of a stable, pasteurized end product suitable for utilization as fertilizer.

Zirsakht Tadbir Arian (ZETA) Company stands as a proficient implementer of cutting-edge and efficient Thermal Hydrolysis Process (THP) systems. We offer comprehensive services encompassing design, engineering, equipment procurement, and construction. Our provided systems are distinguished by their robust performance, user-friendly operation, minimal maintenance demands, and the assurance of a continuous and dependable processing regimen.

Sludge Dewatering

Using mechanical processes

At Zirsakht Tadbir Arian (ZETA) Company, we provide a range of dewatering methods, including belt filter presses, centrifuges, filter presses, and screw presses. These techniques are employed to effectively diminish moisture content, ultimately yielding a solid sludge cake.

Sludge Drying

Softening Silica Removal

In instances where customers necessitate sludge with a moisture content below 10%, we possess the capability to execute sludge drying procedures. Sludge drying is attainable through diverse techniques, encompassing thermal drying methods (such as the utilization of rotary dryers or fluidized bed dryers), solar drying, or mechanical processes like paddle dryers. The ultimate objective of these processes is the production of biosolids or biofuels.
