Abstract

The ready-mix concrete industry plays a crucial role in supplying concrete for various construction purposes. During its production and operational processes, this industry generates wastewater from laboratory activities, mixer van washing, and truck mixer cleaning. The generated wastewater is treated and planned to be reused for road spraying within the industrial area. This paper aims to analyze the characteristics of the generated wastewater and its potential impact on roads, and evaluate the efficiency of its reuse. The total volume of treated wastewater produced is 11.88 m³/day, containing parameters such as pH, TSS, Cl⁻, and SO₄²⁻. Based on the water quality measurements, the treated wastewater meets the quality standards set by the Ministry of Environment and Forestry for pH and TSS, and by Government Regulation No. 22 of 2021 for chloride and sulfate. Therefore, the wastewater is considered suitable for road spraying. The efficiency of using treated wastewater for this purpose reaches 43% during the dry season and 86% during the rainy season.

Abstract

In general, laundry businesses use detergent rather than soap to wash clothes because detergent contains surfactants that are more effective at removing dirt. This washing process produces waste that is usually disposed of directly into the environment. The indiscriminate disposal of laundry waste can cause environmental pollution because it contains pollutants, such as chemical oxygen demand (COD) and surfactants, that exceed established quality standards. The purpose of this research was to test the effectiveness of water bamboo plants in reducing COD and MBAS levels in laundry waste. This phytoremediation method utilizes microorganisms (rhizosphere microbes) living in the root system and planting media. These microorganisms decompose organic and inorganic materials in wastewater into simpler compounds, which are then used as nutrients by the plants. The most effective configuration for reducing COD and surfactant levels in laundry waste is 15 water bamboo plants with a residence time of three days. However, COD levels are still above the quality standard while surfactant levels are below it.

Abstract

The animal feed ration industry in South Kalimantan Province produces domestic liquid waste from supporting activities with quite high levels of pollutants. The waste is processed using a Wastewater Treatment Plant (WWTP) and reused to reduce environmental impacts. This study aims to examine the efficiency of utilizing domestic waste as an alternative water source for watering Green Open Spaces (GOS) in industrial areas. The research method used is descriptive-quantitative based on secondary data. Based on the results of wastewater quality measurements at the WWTP outlet,it shows that domestic waste has met the quality standards according to the Minister of Environment and Forestry Regulation P.68 of 2016 and PP No.22 of 2021 for watering purposes. The animal feed ration industry produces domestic waste of 15.5m³/day with a WWTP capacity of 20m³/day and a planned GOS area of ​​8,715.15m². There are two scenarios for wastewater utilization, namely in the dry season with an efficiency of 40.65% and the rainy season with an efficiency of 81.31% of the total industrial raw water needs. These results indicate that domestic waste in the animal feed ration industry has the potential to be an alternative water source that is environmentally friendly and supports sustainable water management.

Abstract

Wastewater generated from poultry slaughterhouses generally contains high levels of organic matter and ammonia, which can contaminate aquatic environments if not properly treated. The high organic content contributes to elevated COD levels, while ammonia can be toxic to aquatic organisms. This study was conducted to evaluate the performance of a biofilter system with intermittent aeration (anoxic–oxic combination) using tree fern board and bioring media in reducing COD and NH₃-N concentrations. The tested aeration durations included 3 hours (1 hour anoxic, 2 hours oxic), 6 hours (2 hours anoxic, 4 hours oxic), 9 hours (3 hours anoxic, 6 hours oxic), and 12 hours (4 hours anoxic, 8 hours oxic). The experimental results showed that the bioring medium exhibited better performance than the tree fern board, with the optimum condition achieved at a 12-hour hydraulic retention time, resulting in COD and NH₃-N reductions of 93.41% and 88.21%, respectively. Overall, the findings indicate that a bioring-based biofilter with intermittent aeration has strong potential as an effective and environmentally friendly alternative technology for treating poultry slaughterhouse wastewater.
