Abstract

Poly Aluminum Chloride (PAC) is a chemical that is frequently utilized in the treatment of drinking water. It is therefore essential to investigate methods of reducing the dosage of PAC in conjunction with natural ingredients that have the potential to adsorb pollutants in water. This research employs a combination of PAC and aloe vera, utilizing the optimal composition identified in previous research. The research was conducted on a laboratory scale using raw water samples of river water that had been intentionally contaminated with iron. The pollutant parameters measured were iron, organic matter, and ammonia. These parameters were selected as they are likely to be affected by the addition of aloe vera. The results of the treatment using jar tests were evaluated by comparing the quality of the initial water sample, the use of PAC alone, and the use of a combination of PAC and aloe vera. The experimental results demonstrated that the combination of PAC and Aloe vera exhibited superior efficacy in reducing iron levels compared to PAC alone. However, this combination also resulted in a notable increase in organic matter levels in the water samples.

Abstract

One of the pollutants that must be controlled in rivers is the level of nitrite. Excessive amounts of nitrite are detrimental because they affect the quality and health of aquatic ecosystems. This study aimed to determine the effectiveness of eco enzymes in reducing nitrite levels in polluted river water as an alternative to conventional water treatment technologies. Three types of eco-enzyme made from vegetable, tomato and orange waste were used in this study. The experiment also aimed to evaluate the potential of reducing nitrite levels and its effect on pH performance. The results showed that adding 5% Vegetables Eco Enzyme (VEE), Tomatoes Eco Enzyme (TEE) or Oranges Eco Enzyme (OEE) to river water samples with an initial nitrite level of 4.813 mg/L produced the best results, with VEE showing the greatest effectiveness. This is because the nitrite concentration was reduced by 100% in the 4^(th) hour for VEE, the 6^(th) hour for TEE and the 8^(th) hour for OEE. For the pH parameter, there was a significant decrease, but it remained within the quality standard of pH 6–9. Statistical analysis using t-tests and ANOVA showed significant differences in both nitrite levels and pH results, as well as in the type of treatment.

Abstract

Waste water treatment facilities (WWTP) are producing a rising amount of sludge, which poses serious disposal and environmental issues. The purpose of this study is to investigate the possibility of using WWTP sludge in place of filler materials while making NPK fertilizer. Significant levels of vital elements, including nitrogen (N), phosphorous (P), and potassium (K), which are crucial for fertilizer quality, were found in the sludge after a thorough physical and chemical analysis. A comparative assessment was performed between the WWTP sludge and standard clay filler materials to evaluate compliance with Indonesian National Standard (SNI) 2803:2024 for solid NPK fertilizers. Experimental mixing trials identified the optimal sludge-to-clay ratio as 60:40, which produced fertilizer granules with acceptable physical properties, homogeneity, and nutrient content that met the SNI requirements. This study shows that using WWTP sludge as a filler in fertilizer manufacture has major financial advantages in addition to supporting resource recovery and sustainable waste management. The study promotes the use of sewage reuse in fertilizer production as a creative way to solve environmental issues and boost industrial productivity.
