Karangpilang II Water Treatment Plant (WTP) is a part of Karangpilang WTP of Surabaya Water Utilities that serves the water supply for Surabaya City. Karangpilang II WTP has the biggest clean water production capacity in Karangpilang WTP, which is 2500 L/s. Using conventional treatment to remove turbidity, the treatment plant in Karangpilang II WTP consists of pre-sedimentation, clearator and filter units. In this study, evaluation of turbidity quality in production water and turbidity removal efficiency were conducted to analyze the Karangpilang II WTP performance in turbidity treatment. The evaluation was conducted using the 2016 data, by comparing the turbidity of production water with the Water Quality Standard of the Water Utilities, and by comparing the turbidity of raw water, effluents of each treatment unit and production water. The evaluation result showed that in the case of Karangpilang II WTP turbidity removal performance, there were some occurrences that the turbidity in production water has not met the standard quality. The results also showed that there was a unit in the Karang Pilang II WTP with inadequate performance in turbidity removal, namely pre‑sedimentation unit. There are some solutions for the problem of turbidity removal in Karangpilang II WTP: increasing the maintenance schedule for pre-sedimentation unit; determining the proper turbidity reference in determination of coagulant dose; optimizing the coagulant dose; using produced sludge from water treatment as coagulant aid along with Al2SO4; and using capping material in filter unit.

Tofu liquid waste comes from the washing process, boiling, and printing on tofu production. Tofu liquid waste is usually directly discharged into rivers or sewers which can have a negative impact on the environment. Tofu wastewater treatment with activated charcoal adsorption methods can reduce the concentration of pollutants contained in the waste. This research was conducted to determine the effect of variations in stirring speed in the removal of COD and TSS levels in tofu liquid waste. The adsorbent used in this study was activated charcoal from the skin of jengkol (Pithecellobium lobatum) carbonized at 350ºC which was then activated using 1M HCL. The adsorption process in this study used a mass of 2 g of activated charcoal; 4 g, 6 g and 8 g and stirring speed 60 rpm and 120 rpm. The initial concentrations of COD and TSS were 5140 mg/L and 605 mg/L. The results of the research that have been carried out show that the stirring speed and mass of the adsorbent affect the levels of COD and TSS as well as the effectiveness and adsorption capacity. A significant decrease in COD and TSS levels occurred in the treatment using 8 g of activated charcoal and a stirring speed of 120 rpm. The COD value obtained was 1137 mg/L, TSS was 103 mg/L and the efficiency value obtained was COD of 77.88% and TSS of 82.98%.

Tofu industrial wastewater contains a high level of chemical oxygen demand (COD), which may cause negative impacts if not treated before being discharged into the environment. Filtration is one of the simple and effective methods for COD removal in tofu industrial wastewater, utilizing filtration media such as sand and activated carbon. The objective of this research is to evaluate the performance of spent coffee grounds (SCG) activated carbon and river sand as filtration media in COD removal from tofu industrial wastewater. The research was carried out using a dual media filtration unit composed of SCG activated carbon and river sand, with media thicknesses of 15 cm and 30 cm, respectively. The results show that the combination of SCG activated carbon and river sand as filtration media can reduce the COD level in tofu industrial wastewater from 928 mg/L to 307 mg/L (66.92%), although it still does not meet the quality standard (300 mg/L). Based on the findings, it can be concluded that the combination of SCG activated carbon and river sand has the potential to lower COD levels in tofu industrial wastewater, but further improvement is required to enhance its effectiveness.
