Innovative porous mortar filters: wastewater purification for clean water

Abstract

Water scarcity is a major global challenge that affects both developed and developing countries, with Indonesia serving as a prime example. Indonesia's archipelagic nature, combined with its dense population, exacerbates the severity of water scarcity. The increased population density in these areas raises the demand for water resources, putting a strain on the available supply. The purpose of this research was to create porous mortar filters (PMFs) with different ratios (1:4, 1:5, and 1:6) by incorporating 10, 15, and 20% adsorbent material by weight of fine aggregate. The research was carried out in three stages: determining PMF properties, preparing synthetic wastewater, and assessing treatment effectiveness. Various PMF compositions consistently achieved notable success, with reductions in total dissolved solids and turbidity exceeding 25 and 75%, respectively. The PMF performed admirably in eliminating bacterial concentrations, achieving a 100% removal rate, and was critical in efficiently reducing metals, with compositions achieving over 80% reduction for Manganese (Mn) and 38% reduction for Iron (Fe). PMF emerges as a practical solution as a cost-effective and simple water treatment technology, particularly suitable for areas with limited technological infrastructure and resources, providing accessible water treatment for communities facing challenges in this regard.

Purification of surface water by using the corona discharge method

“…In response to the challenges posed by the location of clean drinking water sources at significant depths, exceeding 200 meters, scientists and researchers globally are increasingly directing their attention towards the application of innovative purification methods [40]- [43]. This shift in focus is driven by the need to address the unique challenges asso-ciated with accessing and treating water from surface water sources.…”
