“…Other successful experiences in producing boiler feed water using RO with industrial waste and river water had been demonstrated. [13,14,15].Although the application of membrane technology for wastewater treatment has been widely reported in the past, the investigation on corrosivity of treated water is still very limited. The objective of this paper is to study the affecting factors on corrosion of tertiary-treated municipal wastewater using as makeup water of circulating cooling systems and the performance of some corrosion inhibitor.…”

Tertiary treatment of municipal wastewater is necessary to reduce its scaling potential for using as makeup water of circulating cooling systems. In this study the corrosivity and the factors affecting corrosion of municipal wastewater tertiary-treated by nanofiltration membrane process were assessed by weight-loss method. The results show that concentration of salt ions such as Ca2+, Mg2+, Cl- and SO42- has a significant effect on corrosivity to carbon steel. Certain quantity of calcium and magnesium ions could inhibit the corrosion of carbon steel, however, chlorine and sulfate ions could accelerate the corrosion of carbon steel. The corrosion inhibition effect of three inhibitors (PC-604, RP-101 and poly epoxy succinate (PESA)) in tertiary-treated municipal wastewater on the carbon steel was evaluated. PC-604 had the best corrosion inhibitor effect and the lowest dosage. This research has guiding significance for using tertiary-treated municipal wastewater as makeup water of circulating cooling systems.

This study has applied the concept of the hybrid PAC-UF process in the treatment of the final effluent of the palm oil industry for reuse as feedwater for low-pressure boilers. In a bench-scale set-up, a low-cost empty fruit bunch-based powdered activated carbon (PAC) was employed for upstream adsorption of biotreated palm oil mill effluent (BPOME) with the process conditions: 60 g/L dose of PAC, 68 min of mixing time and 200 rpm of mixing speed, to reduce the feedwater strength, alleviate probable fouling of the membranes and thus improve the process flux (productivity). Three polyethersulfone ultrafiltration membranes of molecular weight cut-off (MWCO) of 1, 5 and 10 kDa were investigated in a cross-flow filtration mode, and under constant transmembrane pressures of 40, 80, and 120 kPa. The permeate qualities of the hybrid processes were evaluated, and it was found that the integrated process with the 1 kDa MWCO UF membrane yielded the best water quality that falls within the US EPA reuse standard for boiler-feed and cooling water. It was also observed that the permeate quality is fit for extended reuse as process water in the cement, petroleum and coal industries. In addition, the hybrid system's operation consumed 37.13 Wh m of energy at the highest applied pressure of 120 kPa, which is far lesser than the typical energy requirement range (0.8-1.0 kWh m) for such wastewater reclamation.
