High operational costs

Traditional sludge dewatering systems can be energy-intensive and require frequent maintenance.

Variable sludge composition:

Fluctuating sludge characteristics impact the performance and consistency of dewatering processes.

Environmental compliance:

Tightening environmental regulations demand low-emission, low-noise, and resource-efficient technologies.

How does it work ?

The process

The sludge dewatering screw press (NSP) uses a wedge-wire drum combined with a unique hose flocculator to separate solids from liquids efficiently. As sludge enters the system, it is conditioned by the hose flocculator, ensuring consistent floc formation even when sludge characteristics vary.

The rotating screw moves the sludge through the drum, where water is gradually removed. An automatic washing system keeps the filtration surface clean with minimal water usage, all while avoiding the wear and tear seen in moving-disc designs.

Lower costs

The screw press (NSP) reduces both sludge disposal and operational costs through its highly efficient dewatering process. By producing a drier sludge cake, it minimizes transportation and landfill fees. The system's low installed power requirement also translates to significantly reduced energy bills over time. Additionally, minimal mechanical wear lowers maintenance frequency and spare part costs.

Adaptability

The screw press (NSP) is engineered with a hose flocculator that adjusts to changing sludge compositions in real-time. This adaptability ensures consistent dewatering performance, even when the incoming sludge varies in thickness or content. It eliminates the need for constant manual adjustments or additional chemical dosing. This makes it ideal for facilities dealing with variable influent conditions

Sustainability:

Designed with environmental considerations in mind, the screw press (NSP) operates with low energy consumption and produces minimal noise, contributing to a reduced carbon footprint. Its automatic washing system conserves water by efficiently cleaning the unit without excessive usage. The screw press (NSP) low metallic wear and tear not only extend its lifespan but also reduce the frequency of part replacements, minimizing waste. Collectively, these features support sustainable wastewater management practices.

On-site demonstrations:

Our mobile units allow potential customers to test performance under real sludge conditions.
