![]() The dense NF90 and reverse osmosis XLE membranes showed almost complete removal (>97.7%), while the NF270 membrane showed a large dependence of removal on initial concentration from 41.9% to 96.6%. In this study, the removal of the anthelmintic mebendazole from aqueous solution was investigated using nanofiltration and reverse osmosis membranes, adsorption on granular activated carbon (GAC), and photolytic degradation. However, their use as antiparasitics and in cancer treatment will increase their already recorded occurrence in the aquatic environment. The idea of using drugs from the benzimidazole group as potential antitumor agents is becoming increasingly popular and widespread in research.

Given your insightful works in the field, we invite you and your colleagues to submit a contribution to this Special Issue in which some leading experts will describe works, ideas, and findings. The Issue accepts high-quality research articles as well as review articles. Important aspects of the Special Issue include treatment and reuse of various wastewaters (model and real). Our focus is also on pretreatments for membrane separation processes to decrease fouling. © Lippincott-Raven Publishers.This Special Issue entitled “UF/NF/RO membranes for wastewater treatment and reuse” focuses on treatment of wastewaters with pressure membrane separation processes (ultrafiltration/nanofiltration/reverse osmosis). (3) The beneficial effect of varying dialysate Na with sequential UF may be due to improved plasma refilling and decreased early intradialytic osmolar changes. (2) The need for mannitol and saline may be more readily alleviated with protocol B than with protocol A. These data suggest: (1) Sequential UF with varying dialysate Na could benefit patients who are hemodynamically unstable. The intradialytic mannitol infusion was 10 ml/HD and 0, whereas saline was 80 ml/HO and 10 for A and B, respectively. The clinical parameters (UF, BP, pulse rate) and serum Na showed no difference. The decrease in serum osmolality during the first and second hours was more marked in protocol A than in protocol B (p <0.05), but post-dialysis values were similar. The plasma volume decreased by 5.3% in protocol A as compared with 1.2% in protocol B, as shown by the Hct values. Hct, BUN, creatinine, osmolality, and serum albumin were checked every hour. BP and pulse were monitored every 30 min. Protocol A was sequential UF (50% weight loss in the first hour, 30% in the second, and 20% in the third hour) with a dialysate Na of 140 mEq/L Protocol B was sequential UF as in protocol A with varying dialysate Na (150 mEq/L in the first hr, 142 in the second, and 137 in the third). Ten chronic patients underwent HD using two protocols. We studied vascular stability during sequential UF with constant and variable dialysate Na. Hypotension is a very common problem during HD. ![]()
