Abstract

The water of Kali Jagir, Surabaya, used as a raw water source, has been contaminated with high levels of BOD, COD, and permanganate. Therefore, this research seeks to address these issues by combining slow sand filtration with various media, including geotekstil and activated carbon. The study aims to optimize this combination in reducing parameters such as permanganate and total coliform in the raw water. The research methodology includes literature review, testing of raw water characteristics, preparation of slow sand filter reactors, preparation of filter media, and testing of media variations with an observation of organic and bacteriological pollutant removal efficiency. The results show that the combination of filter media involving sand, activated carbon, and geotekstil is effective in reducing organic pollutants. Geotekstil aids in the growth of the schmutzdecke layer and facilitates cleaning, while sand and activated carbon tend not to support such growth. Moreover, the optimum schmutzdecke growth time varies depending on the type of media used. These findings have significant implications for raw water treatment in industrial areas vulnerable to pollution, resulting in quality drinking water and addressing the frequent clogging issues in slow sand filters.

Abstract

Nitrogen is one of the organic compounds contained in liquid waste produced by the tofu industry. In aquatic ecosystems, excessive amount of nitrogen can lead to eutrophication and increase the amount of ammonia, nitrate and nitrite which are poisonous to humans, livestock and wildlife. In order to deal with the issues, photo-catalyst technology is employed to process the organic liquid waste by converting themintoCO_2 and water which are relatively safer. Throughout the process, it requires a medium like resin immobilized photocatalyst-ZnO (RIP-ZnO) to absorb the pollutants. Based on the aforementioned background, this study aims to analyze the impact of RIP-ZnO capacity in reducing the total Nitrogen parameter. The analysis of total Ninthisstudy was conducted by using the Kjeldahl method consisting of three processes, namely destruction, distillation and titration. The research began with the process of making reactor and RIP-ZnO. Subsequently, once the total N concentration is known, the process of resin capacity calculation is continued. As a result, the research findings indicate that the highest resin capacity of 1.14542 reduces the total Nby 33%, while the lowest one of 0.00012 decreases it by 59%. In other words, the resin capacity has an impact on the percentage of total N removal. In conclusion, the lower the resin capacity is, the higher the removal percentage is, and vice versa.

Abstract

The production of sweet soy sauce in Indonesia was particularly high in 2021, resulting in wastewater with elevated levels of COD, BOD and TSS. Therefore, wastewater from the soy sauce industry needs to be treated before being discharged into water bodies. In this study, the electrocoagulation method was used to reduce the levels of BOD, COD and TSS. Electrocoagulation is a process in which the anode releases active coagulants in the form of metal ions into the solution and electrolysis reactions occur, releasing hydrogen gas at the cathode. The aim of this research was to determine the effectiveness of electrocoagulation in reducing pollutants such as BOD, COD and TSS in industrial effluents. The study involved varying the distance between the electrode plates and the contact time. The treated wastewater was from a soy sauce industry in Surabaya. The results showed that increasing the electrode distance to 1cm, 2cm, 3cm and 4cm with a contact time up to 180 minutes significantly improved the efficiency of BOD, COD and TSS reduction. The best removal was achieved at 4 cm electrode distance and 180 minutes contact time, with reduction rates of 72.0% for BOD, 83.3% for COD and 90.6% for TSS.

Abstract

The growth and development of industry around rivers has the potential to contribute large amounts of organic waste, namely BOD and COD. The determination of organic matter in water is carried out by measuring the amount of oxygen required in the water to break down the organic matter, either using microorganisms, chemicals or other methods. Adsorption using bioadsorbents can be used to overcome this problem, with bioadsorbents such as corn husks and shallot peels, which have a large surface area and are good at controlling organic substances that are not dissolved in water, making it more efficient to remove BOD and COD parameters. This research aims to analyse the ability of corn husk and shallot peel bioadsorbents to reduce the levels of BOD and COD parameters. In this research, river water from Mangetan Canal and bioadsorbent activated with 5% H3PO4 solution were used. The research results showed that the use of corn husk and shallot peel waste as adsorbent in a continuous adsorption process resulted in optimum percentage removal of BOD of 64.1%; COD of 72.5%; BOD of 73.3%; COD of 85% at 40 minutes contact time.

Abstract

Lake water contaminated with domestic sewage is a serious problem as it can pollute the surrounding environment, as in Telaga Rambit, Gresik. Turbid water quality indicates pollution, so a treatment process is needed before use. This study aims to analyse the effect of activator type and flow rate on the filtration process using the slow sand filter (SSF) method, with a combination of coconut shell charcoal and rice husk charcoal media. The flow rate variations used were 0.1 m³/h and 0.3 m³/h, with hydrochloric acid (HCl) and phosphoric acid (H₃PO₄) activators. The results showed that Reactor B, using H₃PO₄ at a flow rate of 0.1 m³/h, was the most effective variation in reducing pollutant levels, namely BOD by 1.9 mg/l, COD by 6.26 mg/l and TSS by 12 mg/l at the 25th sampling time. The H₃PO₄ activator has been shown to increase the adsorption capacity of activated carbon media, particularly in the capture of suspended solids. The low flow rate also provided better stability during the filtration process, allowing for more effective particle retention. After 25 minutes, the filtration media had not reached saturation point, indicating that filtration could be improved with longer contact times.

Abstract

Waste treatment is the main challenge in the tofu industry, especially for household-scale producers. As a solution, constructed wetland is an affordable, efficient, and easy-to-operate waste treatment method. The tofu industrial wastewater used in this study came from one of the home industries in the park, Sidoarjo. In this study, a variety of planting media and plant types were used. The planting media used are silica sand and gravel; biochar and mixed soil; as well as a combination of silica sand, soil biochar mixture, and gravel. And the plants used in this study are Cyperus Papyrus and Cyperus Rotundus. The purpose of this study is to determine the influence of planting media and the type of plants that will be used in the CW system. All planting media used showed the ability to reduce TSS, COD, and BOD parameters. Although there is a decrease in parameters only with the media, the average efficiency of parameter reduction with plant use has a greater value with a difference of 20% to 25%. For the comparison of the two types of plants, it can be seen that the yield of Cyperus Rotundus is larger, there is a difference in efficiency ranging from 2.5% to 3% with Cyperus Papyrus plant.

Abstract

There are several types of water treatment, namely physical, chemical and biological, with each treatment process depending on the parameters of the pollutant to be treated. Raw water treatment generally uses physico-chemical treatment, which is useful for reducing the levels of pollutants such as TSS and turbidity, usually referred to as the coagulation-flocculation process. In the flocculation process there are different types of modifications, an example of modification is hydrocyclone flocculation. The aim of this research is to obtain information regarding the use of hydrocyclone flocculation reactors in the removal of pollutant parameters such as TSS. This research has been carried out by preparing 3 types of hydrocyclone flocculation reactors with different diameters (10 cm, 15 cm and 20 cm) where tests will be carried out to see the most optimal hydrocyclone flocculation diameter in eliminating TSS and turbidity parameters in the sample water. From the results of the research carried out, the most optimum diameter for the removal of TSS parameters and also turbidity in the sample water is a 20 cm hydrocyclone flocculation reactor with an average TSS removal percentage of 77.85% and an average turbidity removal percentage of 81%. Meanwhile, hydrocyclone flocculation reactor diameters of 10 cm and 15 cm have an average removal percentage of 60% and 70% for TSS, then for turbidity it is 59.8% and 62%.
