“…Along with runoff mitigation, PCP has been most promising in reducing TSS loadings versus IBPG and PICP. This result may be due to its rough and porous surface structure, which is capable of trapping sediments while storing water volume within the surface and media [52][53][54][55][56]. Furthermore, the existing innovative storage design (0.13 m), consisted of #2 open-graded aggregates followed by #52 washed stone, which might be effective in particulate trapping within its enlarged void spaces.…”

This study examines the hydrologic and environmental performance of three types of permeable pavement designs: Porous Concrete Pavement (PCP), Permeable Interlocking Concrete (PICP), and Interlocking Block Pavement with Gravel (IBPG) in the semi-arid South Texas. Outflow rate, storage, Normalized Volume Reduction (NVR), Normalized Load Reductions (NLR) of Total Suspended Solids (TSS), and Biochemical Oxygen Demand (BOD5) were compared to results obtained from adjacent traditional pavements at different regional parking lots. A notable percentage of peak flow attenuation of approximately 31–100% was observed when permeable pavements were constructed and implemented. IBPG was capable to hold runoff from rainfall depths up to 136 mm prior to flooding. PCP was the most satisfactory in reducing surface runoff (NVR: 2.81 × 10−3 ± 0.67 × 10−3 m3/m2/mm), which was significantly (p < 0.05) higher (98%) than the traditional pavement. PCP was also very effective in TSS removal (NLR: 244 × 10−5 ± 143 × 10−5 kg/m2/mm), which was an increase of over 80% removal than traditional pavement. IBPG (NLR: 7.14 × 10−5 ± 7.19 × 10−5 kg/m2/mm) showed a significantly (p < 0.05) higher (46%) BOD5 removal over traditional pavement. These results demonstrate that the type of permeable pavement and the underlying media can significantly influence the runoff reduction and infiltration in this climatic region.

“…This water, which is absorbed through hygroscopic attraction (i.e., charged particle surface area), leads to the increase in volume of water held in the sandy growth medium (Fassman-Beck et al 2015;Rosalina et al 2019;Torkashvand and Shadparvar 2013). This could be due to greater adsorption capacity, negative charge, cation exchange capacity (CEC), and surface area of zeolite particles compared to sand (Rosalina et al 2019;Saghaian Nejad et al 2017). These results imply that the proposed method can be used to improve PAWC and nutrient content in greenhouses, green roofs, and urban green spaces where high permeability growth mediums such as sand are frequently used.…”

The use of high permeability soils with low plant available water content (PAWC) for cultivation of plants in the greenhouses, green roofs, and urban green spaces requires frequent irrigation, which leads to high water consumption. This paper presents an innovative method consisting of combined use of sustainably produced liquid organic fertilizer (LOF) extracted from landscape grass waste and clinoptilolite zeolite for improving PAWC of sand. The study included four substrates, namely sand (S), sand with 20% zeolite (SZ), sand treated with LOF (SLOF), and sand with 20% zeolite treated with LOF (SZLOF), to evaluate the effect of LOF and zeolite on PAWC of sand. The effect of three growth medium treatments, sand that received LOF fertilizer (LOF1), sand with 20% zeolite that received LOF fertilizer (ZLOF), and sand that received inorganic fertilizer (CF1), through a greenhouse experiment during two growing seasons (fall and summer) on productivity of perennial ryegrass (Lolium perenne) and properties of its growth medium was also evaluated. Combined use of LOF and zeolite increased the volumetric water content of sand by 29, 154, and 220% at 0, 30, and 100 centibar (CB) suctions compared to S substrate, respectively, and increased the dry biomass yield (DBY) of perennial ryegrass by 42% in ZLOF during the summer season compared to CF1 growth medium. Additionally, the content of organic matter, nitrogen, and phosphorus increased by 25, 120, and 84%, respectively, for ZLOF treatment compared to 33, 40, and 53% for LOF1 treatment. The outcomes of the experiments demonstrate the feasibility of using LOF and zeolite to improve the PAWC of sand and DBY of perennial ryegrass.

“…O autor reforça ainda ser promissor, o uso do concreto poroso como forma de diminuir o impacto do escoamento urbano poluído e das águas residuais, e o reuso destas em outras finalidades. Nejad et al (2017) destacam que devido aos níveis excessivos desses parâmetros (citando, dentre outros: DQO, turbidez, chumbo e sólidos suspensos totais -SST) encontrados nas águas, impactos negativos podem ser gerados nos ecossistemas aquáticos e humanos saúde, e essas cargas de poluentes podem levar à criação de enormes florações de algas nos lagos receptores e rios, além de subsequente criação de aspecto visual desagradável e condições eutróficas nesses ambientes.…”

Nos grandes centros urbanos, a constante impermeabilização das vias intensifica alagamentos e enchentes, gerando inúmeros transtornos à população. O uso do concreto permeável como mecanismo de drenagem de águas pluviais e residuárias tem sido uma solução parcial para esse tipo de problema de drenagem, inclusive com a adição em sua composição de materiais com propriedades adsorventes que visem a melhoria de parâmetros físico-químicos e biológicos da água. Portanto, este artigo tem como objetivo geral trazer importantes resultados de diversos estudos utilizando concreto permeável com adições minerais e mostrar os benefícios nas propriedades mecânicas e adsorventes desse tipo de concreto, com ênfase na utilização do biocarvão. Para isso, optou-se como metodologia, fazer uma breve revisão da literatura, no qual foram analisadas pesquisas concluídas disponíveis em base de dados online como Scopus, Science Direct a partir do ano de 2015 utilizando como descritores em inglês: “Concrete” AND “Biochar”, “Concrete porous” AND “Biochar”, “Pervious concrete” AND “Biochar”, “Treatment of water” AND “Concrete porous”, “Cementitious materials” AND “Biochar”. Foram selecionadas 51 referências sendo assim especificados: 48 artigos científicos, 1 norma e 2 capítulos de livros. Constatou-se que a adição de minerais adsorventes e biocarvão no concreto podem promover melhoria de parâmetros de qualidade da água como diminuição de turbidez, nitrogênio totais (NT), Fósforo Totais (PT), DQO, DBO, entre outros, e promoverem, em alguns casos, ganho de resistência mecânica dos concretos produzidos.
