Abstract

Seawater is one of the largest natural resources and abundant in Indonesia, which contains salt, metals and mycobacteria. Even though the amount is abundant, its utilization is still not widespread, such as to be used as clean water or drinking water. The use of adsorbents aims to adsorb impurities in the fluid. The adsorption column that is widely used is in the form of a fixed-bed column with messy stacked filling. This makes it difficult to clean and fill the adsorbent, besides the irregular pile of adsorbents will hinder the flow process of the purified fluid. The research product is a circulating portable adsorption column design consisting of 3 parts, namely: top distributor, packing bed, and bottom collector. The principle of the three parts is like a puzzle where the number of packing beds can be adjusted according to the purification needs. The three parts are connected with threads so that they can be disassembled as desired. It is hoped that this product can meet the needs of adsorption-based purification that is easy, inexpensive, and can be customized according to various types of adsorbents. The design of this product can be duplicated for other adsorption purification processes, such as purification of bioethanol, wastewater, and biodiesel.

Abstract

Seawater which contains salt, metal components and mycobacteria is part of Indonesia's natural resources. Behind its abundance, not many benefits can be used, such as clean water to drinking water. Therefore, various technologies are needed to reduce the salt content and other components. In this study, a portable seawater purifier based on the adsorption function was used. The purification apparatus is in the form of a column, and has a series of plates that are placed as a support for the filling material in order to increase residence time and complete the purification process. Materials used as adsorbents in this study include ceramic biological balls, ammonite, volcanic rock, activated carbon and zeolite. Each material is organized in a filter bag for easy installation and cleaning. The equipment construction is arranged where in addition to the column there is also a circulation flow system for seawater to ensure the purification process can run optimally. The circulation process uses a buffer tank and a booster pump back to the column input line. The variable in this study, namely the location of the water sample at Ngobaran Beach, Gunungkidul. Another variable is the filtration rate. Based on the pH value of the TDS analysis and the adsorption results of seawater samples, it can be seen that the 2-stage adsorption process is the most optimal process configuration compared to other levels. This is because the 2-stage adsorption process obtained the smallest TDS value and the most suitable pH value for clean water. The results of this study can be an alternative for an easy and portable seawater purification method. This research can continue to be developed with innovations from the type of filling material and the configuration of the adsorption column used.
