Chapter 1: Techniques

Delta-Stak: A Powerful Solution for Water Treatment

In the world of environmental and water treatment, the name "Delta-Stak" signifies a robust and efficient sedimentation system, renowned for its ability to remove suspended solids from various liquid streams. Developed by Baker Process, the Delta-Stak system utilizes inclined plate settlers, a technology that significantly enhances the separation process compared to traditional settling tanks.

Understanding Delta-Stak

Delta-Stak is essentially a modified inclined plate clarifier, designed to maximize sedimentation efficiency. It operates on the principle of gravity sedimentation, where denser particles settle out of the liquid stream due to their weight. However, the Delta-Stak system significantly amplifies this process by incorporating a series of inclined plates.

The Science Behind Inclined Plate Clarifiers

The inclined plates within the Delta-Stak unit provide a larger surface area for the settling process. As the liquid flows upwards between these plates, the particles experience a longer settling path, allowing for efficient separation. This effectively translates to a reduced settling time and increased capacity compared to traditional settling tanks.

The Delta-Stak system utilizes the following key techniques:

• Inclined Plates: These plates are strategically angled to maximize the settling path of suspended particles. This longer path allows for more complete sedimentation, even for smaller particles.
• Upward Flow: The liquid stream flows upwards through the inclined plates. This upward flow pattern promotes efficient particle settling, as heavier particles are drawn downwards against the flow.
• Lamella Technology: Delta-Stak systems employ lamella technology, which refers to the use of thin, closely spaced plates to increase surface area. This significantly enhances the sedimentation process, resulting in faster settling times and higher removal rates.
• Pre-treatment: Depending on the specific application, the Delta-Stak system may be combined with pre-treatment processes such as coagulation and flocculation to enhance particle aggregation and promote more efficient sedimentation.

By combining these techniques, Delta-Stak effectively optimizes the sedimentation process, achieving high removal rates of suspended solids while minimizing footprint and operational costs.
