Planning for Small-Scale Business (USK) Batik Wastewater Treatment Plant X Yogyakarta

Abstract

Small scale business / Usaha Skala Kecil (USK) X currently does not have a batik wastewater treatment unit. This condition causes the possibility of contamination to water bodies. USK X wastewater treatment applications' planning needs to be carried out sustainably, namely by reusing water. The process units needed in this planning are the sequencing batch reactor (SBR) and constructed wetlands. The effluent of textile wastewater with this system for parameters BOD, COD, TSS, sulfide, total oil & fat, and color were 0.13 mg/L; 106.5 mg/L; 2.4 mg/L; 0.036 mg/L; 0.07 mg/L; and 90.67 PtCo, respectively. The dimensions of the SBR unit required are 0.75 x 0.6 x 1 m. Modification of the SBR unit uses an ozone generator to produce ozone gas which functions as oxidation of organic pollutants and colors in batik waste. After processing in the SBR unit, it is carried out using a constructed wetland with 2.56 m2.

Domestic Wastewater Disinfection Planning for Constructed Wetland Treatment Effluent

“…From the data that has been analyzed, a discussion of each unit will be carried out related to the design criteria and the effectiveness of the disinfectant for the outlet of the constructed wetland planning in the WWTP unit [23]. The discussion was conducted to determine the suitability of the design criteria with the dimensional planning of the WWTP units.…”

Evaluation of domestic wastewater and river management in Belian Village, Batam City Sub-district, Indonesia

“…The increase in the discharge of domestic wastewater produced can cause an increase in the burden of domestic wastewater pollution so that it can reduce the quality of water in the river. Pollution of domestic wastewater can cause an increase in the composition of organic matter in rivers and increase the value of COD and BOD, which causes reduced oxygen in river water and reduces river water quality [22][23][24].…”
