Pre -design Processing Of Lindi TPA Case Study TPA Sending Binjai City

by ADMIN 71 views

Introduction

Lindi water is a type of water produced from various processes, such as waste decay, water infiltration into a pile of garbage, as well as the water contained in the garbage itself. This water flows to the bottom of the pile of garbage and extracts the waste content both dissolved and suspended. If not managed properly, leachate can pollute the environment and endanger living things around it. In this case study, we will discuss the pre-design processing of Lindi TPA at TPA Sending Binjai City.

Background

TPA Sending is a waste treatment site that has been operating since 1985 and is planned to be closed in 2030. With the increase in the volume of waste produced by the City of Binjai, research on the design of the Sanitary Landfill system at TPA Sending is very important. It is estimated that the current leachate water treatment installation unit is unable to process the volume of leachate water produced from the landfill to be designed. Therefore, a new system needs to be designed that is able to process the leachate effectively.

Methodology and Analysis

The leachate discharge generation will be calculated using the Thornthwaite-Matter water balance method, which considers several factors such as precipitation, evapotranspiration, surface flow, and soil moisture storage. The selection of the process unit for leachate water treatment will be adjusted to the characteristics of leachate water from the existing location. In addition, the designed process unit will also follow the provisions in the Minister of Public Works Regulation No. 3 of 2013 concerning the Implementation of Solid Facilities and Infrastructure.

Sampling of leachate water is carried out in the existing leachate processing installation pond (IPL), using the Grab Sampling method. The sample was then tested in the laboratory to evaluate its content. The quality standards used in the analysis are in accordance with the Minister of Environment and Forestry Regulation No. 59 of 2016 concerning Lindi Quality Standards.

From the results of the calculation of the water balance with the Thornthwaite-Matter method, leachate water generation was obtained from the Sanitary Landfill TPA design in the sending of 85.78 m³/day. Analysis in the laboratory shows the characteristics of leachate water with a pH of 7.99, BOD 1328.00 mg/L, COD 2970.00 mg/L, and TSS 308.00 mg/L content. With these characteristics, several process units are chosen to process leachate, namely the equalization tub, anaerobic tub, facultative tubs, wetland tubs, control tubs, and disinfecting processes.

Lindi Water Treatment System Design

The results of the processing installation system designed are expected to produce effluents with BOD content of 30.00 mg/L and COD of 67.09 mg/L. This shows that the planned processing is able to reduce levels of pollutants in leachate water so that it is safer for the environment.

The estimated total investment costs required to build a designed unit amounted to Rp 3,521,100,000.00. These costs include all processing processes needed to manage leachate water effectively and sustainably.

Conclusion

Design of leachate processing systems at the TPA Sending the City of Binjai is very important to maintain the quality of the environment and public health. By applying the right method and following existing regulations, it is expected that leachate management can be done efficiently, reduce the negative impact on the environment, and support the sustainability of waste management in this area. Success in the design and implementation of this system can be a model for waste management in other cities.

Recommendations

Based on the results of this study, the following recommendations are made:

  • The design of the leachate processing system at TPA Sending should be implemented as soon as possible to reduce the negative impact on the environment.
  • The government and local authorities should provide support and funding for the implementation of the leachate processing system.
  • The public should be educated on the importance of proper waste management and the impact of leachate on the environment.

Limitations

This study has several limitations, including:

  • The study only focuses on the design of the leachate processing system and does not consider other factors that may affect the implementation of the system.
  • The study only uses data from the existing leachate processing installation pond (IPL) and does not consider other sources of leachate water.
  • The study only considers the technical aspects of the leachate processing system and does not consider the social and economic aspects.

Future Research

Future research should focus on the implementation of the leachate processing system and the evaluation of its effectiveness. Additionally, research should be conducted on the social and economic aspects of the leachate processing system to ensure that it is sustainable and beneficial to the community.
