Abstract

The authors wish to make the following corrections to their paper [1]: [...]

Highlights

The corrected paragraph, reads as follows: Within the group of technologies applied to physical helminth egg removal from wastewater, land-based post-treatment technologies such as sand filtration, wetlands and polishing ponds are reported to achieve helminth egg removal of 90%–99%, 100% and 100%, respectively [1,25,26]
Jimenez [19] reported that grit removal followed by a coagulation flocculation process in what is known as advanced primary treatment (APT), combined with an upflow sand filtration, reduced the amount of helminth eggs from 1.2 to 0.2 eggs·L−1
A study using APT, followed by a sand filter combined with a synthetic medium, reduced the amount of helminth eggs in

Introduction

The corrected paragraph, reads as follows: Within the group of technologies applied to physical helminth egg removal (not inactivation) from wastewater, land-based post-treatment technologies such as sand filtration, wetlands and polishing ponds are reported to achieve helminth egg removal of 90%–99%, 100% and 100%, respectively [1,25,26]. 1 Environmental Engineering Faculty, National University of Engineering, Lima 25, Peru; E-Mail: bgbcayalal@gmail.com 3 Lettinga Associates Foundation (LeAF), P.O.
