In this research, compost was used as raw materials in the production of biomass adsorbent granules using drum granulation technique. Different concentrations of aqueous sodium silicate solution were used as the binding agents. Chromium and Methylene Blue solutions were selected as model adsorbates for heavy metals and dyes, respectively. The results obtained showed that the concentration of sodium silicate used had a positive influence on the mechanical strength of the granules, increasing the concentration would increase the compressive strength of the granules. The adsorbent granules had sufficient strength to survive wet conditions they were subjected during the adsorption study. However, increasing the concentration has a negative influence on the adsorption properties of the compost granules for both Chromium and Methylene Blue.

在这项研究中，堆肥被用作使用鼓式造粒技术生产生物质吸附剂颗粒的原料。使用不同浓度的硅酸钠水溶液作为粘合剂。选择铬和亚甲基蓝溶液分别作为重金属和染料的模型吸附物。获得的结果表明，所用硅酸钠的浓度对颗粒的机械强度具有积极的影响，增加浓度会增加颗粒的抗压强度。吸附剂颗粒具有足够的强度以抵抗在吸附研究期间经受的潮湿条件。但是，增加浓度对堆肥颗粒对铬和亚甲基蓝的吸附性能都有负面影响。
