Evaluating the Fluid Loss and Carrying Capacity of Water‐Based Muds Treated With Wheat Husks and Periwinkle Shells

Journal of GeoEnergy, Volume 2025, Issue 1, 2025.
The formulation of drilling fluids with the desired characteristics required to achieve a successful drilling operation depends largely on the drilling additives. In this study, we investigated the potential of two agrowastes, wheat husks (WHs) and periwinkle shells (PSs) as additives in water‐based drilling fluids (WBFs).

POTENTIAL APPLICATION OF A LOCALLY SOURCED PHOTOCATALYST FOR THE PHOTOCATALYTIC DECOLOURISATION OF METHYL ORANGE IN AQUEOUS SOLUTION [PDF]

Journal of Engineering Science and Technology, 2015
Periwinkle shell ash (PSA) was investigated for its photocatalytic properties in decolourising methyl orange in aqueous solution. The effects of irradiation time, initial dye concentration and PSA dosage on the decolourisation process were investigated ...

Synthesis of biocompatible hydroxyapatite from quail eggshell, oyster shell, and periwinkle snail shell

Journal of Applied Research on Science and Technology (JARST)
This study focuses on the synthesis of hydroxyapatite (HA, Ca10(PO4)6(OH)2) from calcium carbonate (CaCO3)-rich quail eggshells, oyster shells, and periwinkle snail shells (Filopaludina bengalensis) through the use of the wet precipitation method. The methodology involved calcining the shell waste to convert CaCO3 to calcium oxide (CaO), undergoing ...

Use of Egg Shell Powder and Periwinkle Shell Ash to Strengthen the Engineering Properties of Clayey Soil

INTERANTIONAL JOURNAL OF SCIENTIFIC RESEARCH IN ENGINEERING AND MANAGEMENT, 2023
Recently, the stabilization of clayey soil (CS) has drawn the attention of numerous researchers. In the past, Egg Shell Powder (ESP) and Periwinkle Shell Ash (PSA) were individually tested for their ability to stabilize clayey soil. The author has attempted to stabilize the clayey soil by combining the two of them.
