LITERATURE REVIEW ON THE EFFICIENCY OF ANTISCALANTS WITH DIFFERENT CHEMICAL BASES

Abstract

Introduction:
Reverse osmosis (RO) is a method for purifying water. Ir separates water from incrustations, through semi-permeable membranes; absorption of scales can cause
damage to the membranes, affecting the process. Injecting antifouling removes and
inhibits its overproduction. The objective of this scientific article is to learn about
antiscalants, using as a method the bibliographic review of previous works that have
operated with these, through the analysis of their processes and conclusions, to study
how they vary from each other and which one implies better results.
Objective:
To analyze the most common antifoulings today through a bibliographic review, where compounds that have metaphosphates and polymers as a chemical base are studied.
Materials and Methods:
The review of 3 original publications that posed as the main topic the use of different
antiscalants and their action on the membranes of reverse osmosis equipment was
carried out. The reviewed articles were published in the 2018-2021 period, taking into
consideration the quality and nature of the publications.
Results and Discussion:
According to the comparative analysis of the chosen antiscalants, the effect they have
with respect to the membranes of reverse osmosis equipment was monitored. To
analyze the results, aspects of function, dosage, injection point and conclusions obtained from each one were considered.
Conclusions:
Compared to phosphinocarboxylic acid and the modified base, sodium hexametaphosphate has shown better results in the industry with respect to reverse
osmosis membranes in water purification processes.
