ANALISIS EKOEFISIENSI DAUR ULANG AIR LIMBAH MESIN WASHING IP DI PT X

The amount of water usage is not comparable to the amount flowed to WWTP due to the remote location and indications of leaks in the wastewater piping system, so an ecoefficient analysis of wastewater recycling of IP washing machines at PT X is needed. The type of data in this study consists of primary and secondary data. The primary data needed are the amount of clean water usage per machine, the amount of wastewater generation, and the effluent quality of wastewater. The results showed that the efficiency process was carried out by analyzing clean water usage, measuring wastewater generation, calculating the cost of using clean water and wastewater treatment costs, as well as measuring effluent quality on color parameters and TDS. It is obtained that the effluent quality results still meet government regulatory standards, so that it can be used as raw water in applying wastewater recycling, and wastewater can be flowed directly through sand filter media and carbon filters contained in IP plants, without being treated first at wastewater treatment plants. The amount of savings in implementing ecoefficiency in reducing groundwater use is 87% or 2331.8 m3 / month from the use of IP washing process water and wastewater treatment cost savings of Rp 3,807,370 / month.
