The Chubu economic region, anchored by the City of Nagoya and the Port of Nagoya, presents a unique set of geotechnical engineering challenges. With extensive alluvial deposits, high water tables along the Ise Bay, and dense urban networks, civil engineering projects—ranging from Nagoya Subway extensions to heavy industrial port foundations—require sophisticated slurry-supported piling and deep excavation techniques.
Under these conditions, standard bentonite and polymer slurries quickly become contaminated with fine sands, silts, and abrasive clays. SINOVO Group’s specialized desanding systems are specifically configured to handle Nagoya's challenging soil strata, ensuring clean recycling of drilling fluids, protection of downstream hydraulic machinery, and strict compliance with Japan’s environmental guidelines for waste mud disposal.

A rigorous examination of centrifugal separation parameters for maximizing fluid life in foundation drilling.
At the heart of the SINOVO desander is the polyurethane hydrocyclone. The feed slurry is pumped tangentially into the cylindrical section under pressure ($0.2 \sim 0.4 \text{ MPa}$). This creates a powerful vortex, generating centrifugal forces thousands of times greater than gravity.
Heavier solid particles (sand, gravel, coarse silt) are forced outward against the wall and descend downward through the conical section, discharging as underflow onto the high-frequency vibrating screen. The clean liquid phase remains in the center of the vortex and rises to discharge through the overflow pipe back into the active mud tank.
| Parameters | Standard Bentonite | Polymer Slurry |
|---|---|---|
| Max Inflow Density | 1.20 g/cm³ | 1.05 g/cm³ |
| Average Sand Removal | > 95% (> 50μm) | > 98% (> 74μm) |
| Recommended pH | 8.5 - 10.0 | 7.0 - 9.0 |
Unlike standard separation units, SINOVO mud desanders utilize premium polyurethane screen panels with a negative-angle layout. This layout prevents blinding and screen wear when processing abrasive granulates typical of Nagoya's marine deposits.
