A hydrosieve screen is a cost-effective and efficient sieve used for separating solids from liquids. It utilizes a durable stainless steel bar screen with a triangular cross-section, also known as a waterfall sieve. The velocity of the incoming liquid is used to separate the solids. Its effectiveness has been proven through numerous installations worldwide across various applications.
Key Characteristics:
• No moving parts (static operation)
• Gravity-driven filtration
• Wedge wire anti-clogging surface
• Continuous operation
The operating principle of the hydro sieve relies on the Coandă effect, where the liquid forms a hydraulic attachment to the bars of the screen plate. Unlike straight bars, these bars have rounded angles and are configured in a wavy pattern. As a result, the liquid passes through slots while the separated solids remain on the front face of the screen plate. The screen plate is designed with three distinct angles to ensure efficient elimination of liquid, deceleration of screenings, and drainage.
To support this screen plate, there is a frame that promotes even distribution of effluent across its width before accelerating it down the screen plate. The filtered liquid is collected in the base beneath the screen plate. Together, these components form what is known as Hydro Sieve.
The operation is based on gravity flow and surface filtration:
• Liquid flows onto the screen surface
• Water passes through wedge wire slots
• Solids remain on the surface
• Solids slide downward due to gravity
In advanced designs, the Coanda effect improves flow distribution and enhances separation efficiency.
| Feature | Hydrosieve Screen | Rotary Drum Screen |
|---|---|---|
| Energy consumption | None | High |
| Moving parts | No | Yes |
| Maintenance | Low | High |
| Clogging resistance | High | Medium |
| Operating cost | Low | High |
Hydrosieve screens are ideal for low-energy, high-solids filtration, while rotary drum screens suit automated mechanical systems.
