Deep Filtration Apparatus Manufacturer,Supplier and Exporter in India

Product Code : SCL-CELE-14203

The Depth Filtration Apparatus demonstrates one of the most important processes in water and wastewater treatment — the removal of suspended solids by sand filtration. The unit enables comprehensive study of filtration through a granular medium, observation of pressure variation across the filter bed, and the complete filtration and backwashing cycle.

During operation, raw water containing suspended solids is pumped from the top into the sand filter. As water passes through the filter bed, solids are trapped within the pores of the sand layers, while clarified water (filtrate) exits from the bottom and collects in a tank. Over time, accumulated solids increase the pressure drop across the bed, reducing flow rate. The unit allows visualization and measurement of this process and its regeneration through backwashing with treated water, which restores filter performance.

This apparatus provides clear visualization, accurate measurement, and comprehensive control of all parameters relevant to depth filtration — making it ideal for teaching, research, and laboratory training in environmental, chemical, and civil engineering courses.

Key Features

1. Demonstrates removal of suspended solids by depth filtration using a sand filter.
2. Enables plotting of Micheau diagrams (pressure variation along the filter bed).
3. Investigation of pressure losses during filtration and backwash cycles.
4. Differential pressure gauge and 10 tube manometers for accurate visualization of pressure distribution.
5. Separate raw water and treated water tanks with dedicated pumps for filtration and backwashing.
6. Electromagnetic flow rate sensor for precise flow measurement.
7. Four electrically actuated shut-off valves for automated flow control.
8. Adjustable filter velocity to study effects on filtration performance.
9. Software-based control and data acquisition system via USB for real-time monitoring and recording of parameters.
10. Optional use of diatomite or fine suspensions to simulate raw water conditions.
