Abstract

The principles of wastewater treatment is to convert the objectionable material to less objectionable form, to dispers the pollutants so that their concentration are minimal, or to concentrate them for isolating them from the environment. Detergent content in domestic wastewater disposal has different characteristics from the others thereby they need special approach to remove from the effluent. This research intend to recognize whether there is correlation between detergent content and the other water quality parameters. Thereafter tried to treat domestic wastewater with coagulation flocculation process use alum as coagulant and dry clay which called “Ampo” as coagulant aid, then rapid mixing is conducted along  5 minutes, this process continue with sedimentation.This research is conducted in laboratory scale use simulation water. Detergent content varies from 20 mg/l to 180 mg/l. The parameters are pH, Total Dissolved Solid (TDS) and KMnO4. Research finding shows that there is linear correlation between detergent content with pH and TDS, for KMnO4 the correlation undefinitive. It also found that there are increasing water quality that indicated with decreasing parameters after the treatment.

Abstract

The characteristics of wetlands can be recognized through their hydrological and ecological conditions. The hydrology of a wetland determines whether it can function initially or change. Research on the hydrology of wetlands can start from applying an appropriate water balance and a runoff generation formula for a wetland. Hydrological analysis of wetlands, including peatlands as part of watersheds, requires proper research according to the circumstances. A water balance formula calculating the equilibrium between rainfall, evapotranspiration, surface water, and groundwater is essential for recognizing wetland conditions. Analysis of the watershed flow where the wetland is located can use the rational formulas and the unit hydrograph methods of generated flow that consider suitability for the wetland conditions. This analysis is carried out by calculating the influence of variables on the wetland; rainfall, surface flow, and water detention. Other variables related to soil properties have an influential aspect in determining flow generation. The overall variables effect is reflected in the changes in the downstream flow hydrograph of a watershed. It mainly seems in the recession curve of the flood hydrograph. The peak of the flow decreases in order to wetland presence. This change is a composite of the upstream flow alteration and wetland storage influence. The influence of wetland areas is also found in flood volume, which shows a proportional relationship, namely that the increase in wide wetland areas affects the decrease in flood volume.

Abstract

Indonesia has risk to get a flood event every year since big intensity rainfalls occur every year. Some waterworks will ‘be required to anticipate from it. The flood design number should be available. One of method which mostly used to be applied is unit hydrograph. Unit hydrograph concept firstly is defined by Sherman in 1932. It still be developed by many researchers to get any unit hydrograph basin both actual unit hydrograph and synthetic unit hydrograph. Since the characteristics of some unit hydrograph basin are specifics, researches to discover any unit hydrograph the basin are significant. This research attends to obtain the representative unit hydrograph of Bedog basin in Yogyakarta province. The result shows characteristics of representative unit hydrograph are depend on rainfall intensity due to its distributions and the flood hydrograph figure.

Abstract

Detergent is one type of pollutants that found in domestic wastewater disposal, especially produced from laundry activities. Accumulated detergent physically effected to water body causes foaming and high turbidity therefore causes bad smell. Nowadays, there are no many well known research easily and effectively to remove detergent content. This research proposes an easy and moderate process to remove detergent content from domestic effluent with cheap and available materials. It can useful as references to design some unit operation of wastewater treatment for domestic effluent with detergent contents. For this aim, it has chosen a treatment system coagulation flocculation which give alum coagulant and dry clay coagulant aid called “ampo”, thereafter rapid mixing is conducted along 5 minutes, this process continue with sedimentation. This research is conducted in laboratories scale use simulation water thereafter, tried to the real wastewater effluent. Detergent content variable vary from 20 mg/l, 60 mg/l and 100 mg/l then optimum alum dosage is determined. It is used to determine the optimum dosage alum-dry clay “ampo” combination with various detention time variables. Research finding shows linear correlation between initial detergent content with less of it. It means that if the more detergent content used the lower efficiency occur. The detention time also influence in process decreasing of detergent content, 48 hours is the best condition. Optimum condition found at optimum dosage alum 125 mg/l and ampo 25 g/l and the 48 hours detention time which reach 41%.in efficiency.
