Wastewater Treatment

From upstream interception to downstream dewatering support, Slit&Hole delivers high-efficiency solid-liquid separation solutions centered on precision wedge wire technology. We help industrial and municipal plants stabilize effluent quality while reducing sludge handling and disposal burden.

Typical applications include pre-screening, rotary/static screens, thickening/dewatering pre-protection, sludge reduction, and transfer-line screening.

Key benefits: automation-ready operation, compact footprint, anti-clogging design, reduced maintenance and waste hauling costs.

Applications: Industrial wastewater, municipal sewage, food processing, electroplating effluent.

Rotary Drum Screen

Rotary Drum Screen

Rotary drum screens are pre-treatment or primary treatment units in wastewater treatment systems, commonly used for the initial filtration of sewage, wastewater, and sludge. They are particularly suitable for treating liquids containing high levels of suspended solids and fine residues, thereby reducing the load on subsequent treatment units.

Static Sieve Screen (Inclined Screen Filter)

Static Sieve Screen (Inclined Screen Filter)

Inclined screens are solid-liquid separation equipment used in wastewater treatment. Their primary function is to remove large suspended solids and floating materials from the incoming water flow.
