BACKGROUND: Surfactants are always used as collectors to form complexes with the hazardous materials of wastewaters in foam fractionation. An important topic is how to reuse the surfactants in the process of recovering the hazardous materials. In this work, a novel technology of foam fractionation coupled with adsorption separation was developed for separating streptomycin sulfate (SS) from its simulated wastewater and reusing the collector sodium dodecyl sulfate (SDS).

“…Lu et al used cetyl trimethyl ammonium bromide (CTAB) as the collector to remove dyes from real textile wastewater. Han et al and Li et al investigated the foam fractionation of SS using SDS as the collector. The studies mentioned above show that the surfactants are effective for removing hazardous materials using foam fractionation.…”

“…When this foam is broken into the so-called ''foamate'' stream, the surfactant in the solution is enriched since the foam has a relatively high surface area for a specific volume of interstitial liquid (17,18). The technology has been widely applied in bioseparation engineering, such as the separation of proteins (15,(19)(20)(21)(22), antibiotics (23,24), and other bioactive compounds (25)(26)(27) in recent years.…”

The purpose of this study was to investigate the use of foam fractionation to recover saikosaponins. First, the solvent extraction method was applied for the extraction of saikosaponins from radix bupleuri using ethanol or deionized water. Then, the foam fractionation technique in batch mode was used for the recovery of the total saikosaponins from the extract. The effects of initial concentration, air flow rate, liquid loading volume, pH, and operating time on the process performance were investigated. The recovery percentage 77.2% and an enrichment ratio 3.68 of total saikosaponins with one-stage separation were obtained under the optimal conditions of initial saikosaponin concentration 0.18 mg/mL, air flow rate 50 mL/min, liquid loading volume 200 mL, pH 5.5, and operating time of 2 h. A two-stage foam fractionation technology was also designed, which was effective for improving both the recovery percentage and enrichment ratio simultaneously.

“…At present, ion exchange is mainly used for the plant‐scale isolation of SS from the fermentation broth. During the separation process, a large amount of the wastewater is produced, which has a SS concentration as high as 0.5 g/L 2. Biodegradation is preferred in the industrial treatment of the SS‐containing wastewater.…”

Industrial discharges from manufacturing streptomycin sulfate (SS) are inhibitory to biological wastewater treatment and need to be stripped of residual SS. For effective SS recovery from the wastewater, a two-stage foam separation technology was investigated using a column with a vertical ellipsoid-shaped channel (VEC) and a conventional one, and sodium dodecyl sulfate (SDS) served as the collector. The mechanism of enhancing foam drainage by VEC was theoretically analyzed. In the first stage, the column with VEC was used and under the optimal conditions of the liquid-loading volume 300 mL, volumetric airflow rate 100 mL/min, the initial pH 7.0 and the molar ratio of SDS to SS 8.0, an improved SS enrichment ratio of 16.7 was obtained. In the second stage, a conventional column was used and with a volumetric airflow rate of 450 mL/min, the foamate had a SS concentration of about 0.5 g/L, so it was used as the feed solution of the first stage. By the two-stage technology, the total SS recovery percentage reached as high as 99.7%. Thus, it was significantly effective for the two-stage foam separation technology to recover SS from the simulative wastewater.
