Abstract

The WTP are responsible for the production of drinking water to be consumed by the population, which generates social benefits, however, as in any manufacturing industry, waste is generated and there is the need to dispose them properly without harming the environment. The solid waste management included waste destination and for this stage is necessary to know the waste characteristics in order to define the best treatment and disposal. This study aimed to characterize the WTPS produced by a WTP in the state of Goiás, Brazil, that employs in their treatment the coagulant aluminum sulfate. Physico-chemical analyses and structural properties were verified, showing that the residue consists of clay (mainly the mineral kaolinite and halloysite), silt and sand. The residue was determined as not plastic. The EDS analysis detected the presence of aluminum, which is related to the phosphorus removal in water and sediment, which facilitates their reuse in the wastewater treatment

Ethical guidelines for journal publication

The REMOA is committed to ensuring ethics in publication and quality of articles. 
Conformance to standards of ethical behavior is therefore expected of all parties involved: Authors, Editors, Reviewers, and the Publisher.

In particular, 

Authors: Authors should present an objective discussion of the significance of research work as well as sufficient detail and references to permit others to replicate the experiments. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. Review articles should also be objective, comprehensive, and accurate accounts of the state of the art. The authors should ensure that their work is entirely original works, and if the work and/or words of others have been used, this has been appropriately acknowledged. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. Authors should not submit articles describing essentially the same research to more than one journal. The corresponding author should ensure that there is a full consensus of all co-authors in approving the final version of the paper and its submission for publication.

Editors: Editors should evaluate manuscripts exclusively on the basis of their academic merit. An editor must not use unpublished information in the editor's own research without the express written consent of the author. Editors should take reasonable responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper.

Reviewers: Any manuscripts received for review must be treated as confidential documents. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviews should be conducted objectively, and observations should be formulated clearly with supporting arguments, so that authors can use them for improving the paper. Any selected referee who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the editor and excuse himself from the review process. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
