“…Shells are composed of compounds such as calcium carbonate, chitin, calcium hydroxyapatite, and calcium phosphate. Most shells contain chitin which is a natural polysaccharide that has many uses, such as chelating agents, emulsifiers, and adsorbents [11] so that shells can be used as a filtration medium to raise the pH of wastewater. Shell also has a removal value of COD parameter up to 80.6 percent at media thickness of 122 cm and HRT of 36 h [12].…”

BACKGROUND: Domestic wastewater can cause health problems and pollute groundwater sources. Such pollution not only has a negative impact on health and the environment, but also on the cost in providing clean water. AIM: The outcome of domestic wastewater treatment through a proper technique is expected to meet the clean water quality standard for sanitation purposes. MATERIALS AND METHODS: The experiment was conducted to determine the effect of Hydraulic Retention Time (HRT) on the levels of Biochemical Oxygen Demand (BOD) and Total Suspended Solid (TSS) of domestic wastewater. The experiment was carried out with 6 variations of HRT, namely 1 hour, 2 hours, 4 hours, 6 hours and 8 hours with 4 repetitions. The media running process was carried out for 14 days until the reactor condition was in steady state. RESULTS: The results showed that the removal values for COD, Oil and Fat, Ammonia and Total Coliform parameters were 68.03%, 46.51%, 69.64% and 68.99%, respectively. Based on the variation of HRT of 1 hour, 2 hours, 4 hours, 6 hours and 8 hours on the BOD parameter, the removal values obtained were 11.7%, 21.3%, 34.7%, 49.0% and 64.1%, respectively. Furthermore, for the TSS parameter, the values obtained were 17.3%, 25.4%, 30.6%, 42.3% and 50.4%, respectively. CONCLUSION: HRT was proven to have a significant effect on the levels of BOD and TSS of domestic wastewater with a p-value of <0.05 at the 95% confidence level

“…Besides, the density of GIC and GIC1 samples was observed to increase as the ageing time increased from 1 day to 21 days. The increase in density along with ageing time is due to the increment in ratio of bound to unbound water [ 25 , 28 ]. The reaction in the GIC matrix occurs with the presence of water as a medium of setting reaction over a period of time.…”

“…On the other hand, the carbonate group depicted by C–O vibration mode at wavenumber ~1460 cm −1 confirmed the involvement of carbonate precursors in the production of GIC samples. Besides, Khiri and co-workers explained the formation of asymmetric COOH band at 1550 cm −1 which originated from the carboxyl group in PAA used in the formulation of GIC [ 25 ]. The cross-linking reaction of the carboxylic group was observed in all cement samples due to an active reaction that occurred between PAA and ASF glass ceramics.…”

Glass ionomer cement (GIC) is a well-known restorative material applied in dentistry. The present work aims to study the effect of hydroxyapatite (HA) addition into GIC based on physical, mechanical and structural properties. The utilization of waste materials namely clam shell (CS) and soda lime silica (SLS) glass as replacements for the respective CaO and SiO2 sources in the fabrication of alumino-silicate-fluoride (ASF) glass ceramics powder. GIC was formulated based on ASF glass ceramics, polyacrylic acid (PAA) and deionized water, while 1 wt.% of HA powder was added to enhance the properties of the cement samples. The cement samples were subjected to four different ageing times before being analyzed. In this study, the addition of HA caused an increment in density and compressive strength results along with ageing time. Besides, X-ray Diffraction (XRD) revealed the formation of fluorohydroxyapatite (FHA) phase in HA-added GIC samples and it was confirmed by Fourier Transform Infrared (FTIR) analysis which detected OH‒F vibration mode. In addition, needle-like and agglomeration of spherical shapes owned by apatite crystals were observed from Field Emission Scanning Electron Microscopy (FESEM). Based on Energy Dispersive X-ray (EDX) analysis, the detection of chemical elements in the cement samples were originated from chemical compounds used in the preparation of glass ceramics powder and also the polyacid utilized in initiating the reaction of GIC.

“…In another sense, the large variability in size and also the static friction coefficient of clam shells on different materials have also been investigated to improve the mechanical processing of clam shells into powders of various granulometries [60]. The flexibility of use and the large availability of clam shells also allowed them to be used as a precursor, together with soda lime glass waste, for the formation of glass ionomer cement, i.e., a mixture of glass and an organic acid, for prospective use in dentistry [61]. Clam shells also possibly represent the most viable source of biogenic calcium carbonate for reasonably easy application in the fields of both polymer and cement composites.…”

Natural and renewable sources of calcium carbonate (CaCO3), also referred to as “biogenic” sources, are being increasingly investigated, as they are generated from a number of waste sources, in particular those from the food industry. The first and obvious application of biogenic calcium carbonate is in the production of cement, where CaCO3 represents the raw material for clinker. Overtime, other more added-value applications have been developed in the filling and modification of the properties of polymer composites, or in the development of biomaterials, where it is possible to transform calcium carbonate into calcium phosphate for the substitution of natural hydroxyapatite. In the majority of cases, the biological structure that is used for obtaining calcium carbonate is reduced to a powder, in which instance the granulometry distribution and the shape of the fragments represent a factor capable of influencing the effect of addition. As a result of this consideration, a number of studies also reflect on the specific characteristics of the different sources of the calcium carbonate obtained, while also referring to the species-dependent biological self-assembly process, which can be defined as a more “biomimetic” approach. In particular, a number of case studies are investigated in more depth, more specifically those involving snail shells, clam shells, mussel shells, oyster shells, eggshells, and cuttlefish bones.
