@article{Evi Nur Cahya_Eva Arifi_Riyanto Haribowo_2020, title={RECYCLED POROUS CONCRETE EFFECTIVENESS FOR FILTRATION MATERIAL ON WASTEWATER TREATMENT}, volume={18}, url={https://geomatejournal.com/geomate/article/view/641}, abstractNote={<p>The use of concrete waste from the demolition of buildings is one of the conservation efforts to reduce its environmental impact. In this study, concrete waste was destroyed by the size of coarse aggregates, then made into porous concrete. Porous concrete from recycled coarse aggregate was used as filtration media to reduce the pollutants in wastewater to satisfy the water quality standards. For this purpose, wastewater from the communal wastewater treatment plant was filtrated through two layers of porous concrete made of recycled coarse aggregate with several different sizes, and the water quality output of the system was measured<br>according to water quality parameter standard. The objective of this study is to examine the effectiveness of the aggregate sizes of normal coarse aggregate compared to recycled coarse aggregate as filtration media. From the result of the water treatment filtration model, it was found that the size of coarse aggregate in the porous concrete mix has a significant effect for reducing the water pollutants, as biological oxygen demand (BOD), chemical oxygen demand (COD) and total suspended solids (TSS). As a result of this study, porous concrete made from recycled coarse aggregate shows better performance on filtrating the water pollutants. </p>}, number={70}, journal={GEOMATE Journal}, author={Evi Nur Cahya and Eva Arifi and Riyanto Haribowo}, year={2020}, month={Jun.}, pages={209–214} }
