- ... The use of agricultural wastes (groundnut shell, orange and banana peel, rice husk, coconut husk and Wawa tree saw dust) as potential cost-effective adsorbent for heavy metal removal from wastewater was evaluated. The effect of pH (2.0–6.0), adsorbent dosage (0.6–2.2 g), contact time (10–130 min) and initial concentration (Pb: 5–105 mg/L, Cu and Zn: 2.5–52.7 mg/L) on the metal removal efficiency a ...

- ... The role of total solids (TS) content in anaerobic digestion of selected complex organic matter, e.g. rice straw and food waste, was investigated. A range of TS from wet (4.5%) to dry (23%) was evaluated. A modified version of the Anaerobic Digestion Model No.1 for a complex organic substrate is proposed to take into account the effect of the TS content on anaerobic digestion. A linear function th ...
