Effect of using porcelains on the performance of water and wastewater treatment

Abstract EN

In this study the local materials (Porcelains) was tested as coagulant aid with alum.

Also, it was used the porcelains material as a dual media with sand to determine the efficiency of this material.

This was done by doing the experimental work, to improve the performance of the coagulation and filtration processes used in water treatment plants.

The work required installing of a pilot plant system ; the experimental work was included tests for both water and wastewater.

the initial turbidity for experiments was between (10-200 NTU).

The results indicated that the porcelains material has more efficient in the removal of turbidity for all levels of turbidity and more efficient in removal of BOD5 in the coagulation and filtration processes.

The average of efficiency of turbidity removal with the initial turbidity of (10, 50, and 100, 150, 200 NTU) were (72.8, 84, and 91 %) respectively when adding alum only in the coagulation process.

These percentage were increased to a value of (79, 93, and95 %) respectively when using alum with coagulant aid of porcelanite material.

Also, the results of present study referred that when using the porcelanite material as a dual media with sand in the filtration process, the percent of turbidity removal was about of (87 %), while the removal efficiency by using single media was about of (74 %)when using alum only in the coagulation process.

The efficiency was increased to about (93 %) and (80 %) by using the dual media and single media respectively when using porcelanite material with alum in the coagulation process.

The local alum was gave the removal efficiency of BOD5 of about (46 %),while when using porcelanite with alum the removal efficiency was increased to a value of about (61 %).

In the filtration process the removal efficiency of BOD5 by using dual media was better than that by using single media by about of (18 %) when using alum only in the coagulation process.

When using the porcelanite material with alum, the removal efficiency by using dual media better than that by using single media also by about (25 %).
