Tube Settlers vs. Plate Settlers: Comparing Lamella Technologies

#1
The sedimentation process in both water and wastewater treatment is a physical process which relies on gravity to settle and remove suspended solids. Advanced solids settling processes typically utilize lamella, commonly referred to as tube settlers or plate settlers, to reduce the vertical distance solids particles must fall until hitting a “settling surface”. Higher flow rates, better effluent quality, and more compact sedimentation basins can all be achieved with both types of lamella sedimentation equipment. Although both operate on the same principles of solids settling and can be used as basis of design in many cases, there are several notable differences between the two technologies.

Characteristics of Tube Settlers and Plate Settlers

Tube settlers utilize multiple adjacent tubular channels that are sloped at a nominal 60° angle and combine to form an increased effective settling area. The size and shape of the tubular channels vary by manufacturer. Brentwood’s tube settler design features a trapezoidal shape created by thermoforming PVC sheets.

Polyhedral Hollow Ball packing is made from heat resistant and chemical corrosion resistant plastics, and the application temperature in media ranges from 60 to 150 degrees.

Plastic Polyhedral Hollow Ball (PP, PE, PVC, CPVC, RPP ) is also called plastic multi-aspect hollow ball, polyhedral hollow ball packing composed of two hemispheres which will form into a ball. And each hemisphere consists of a number of half fan-shaped leaves, the upper and lower leaves in a staggered arrangement. The design concept is advanced and the structure is reasonable. Plastic Polyhedral hollow balls have the virtue of light weight, wide free space, small wind resistance, and good surface hydrophilic, big full wet surface area and convenient filling in the equipment and sound usage effect.

Plastic polyhedral Hollow Ball can be used in sewage treatment, desulfurization of CO2 in power plant, desulfuration and purified water tower packing. Plastic multi-aspect hollow ball is a new type of high-efficiency tower packing applied in water treatment equipment.
