“…The ratio BOD 5 /COD clearly indicates the biodegradability of the wastewater, thus allowing for biological treatment. The deficiency of macronutrients (N and P) is obvious . Nevertheless, a significant portion is not easily biodegradable, and a subsequent treatment is necessary.…”

Supercritical water oxidation (SCWO) provides high destruction efficiencies for a wide variety of hazardous wastes at low reactor residence times. This paper studies the feasibility of the SCWO process for the treatment of the esterification wastewater from the poly(ethylene terephthalate) (PET) industry, for which the major contaminant product is ethylene glycol. Both the feed and the liquid-phase product were analyzed in terms of total organic carbon (TOC) to determine the efficiency of the process. Effluent from the PET industry contained 16000 mg/L TOC, equivalent to 4 wt % ethylene glycol. Experiments were carried out in a pilot plant equipped with a pressure shell and a cooled-wall reactor. The effects of temperature and oxidant concentration on removal efficiency were investigated. Tests were performed in the range of 550−750 °C at a pressure of 23 × 106 Pa. Results showed elimination efficiencies of up to 99.9% at 630 °C and residence times of less than 50 s. The scale-up of this plant has been simulated using the software Aspen Plus.

Anaerobic biogranulation is an emerging wastewater treatment technology for industrial applications. As a result of increasing basic understanding and acceptance toward the anaerobic granular processes, a growing interest and confidence in the technology has resulted in a remarkable increase of full‐scale plants installed worldwide over the past few decades. While the technology is well accepted and much research work had been conducted on granule formation, insight unfolding the granulation remains unclear. This article presents a review documenting hypothetical elucidations on anaerobic granule formation and granulation mechanisms. The article also provides detailed discussion on applications of anaerobic granulation with emphasis on reactor systems, emission mitigations, and bioenergy production. Prospects and challenges of anaerobic granulation for wastewater treatment are also outlined.
