Abstract

Prior to modification of the WWTP, BPPT building has had a domestic waste water treatment plant with a lagoon aeration system using activated sludge process. Due to the quality of the current WWTP outlet not meet quality standards waste disposal in accordance with the Governor Regulation DKI No. 122 in 2005, it is necessary to optimize the existing WWTP process and needs to be modified in order to produce quality process WWTP outlet that can meet quality standards. WWTP modification is accomplished by the addition of biofilter reactor, which has been proven reliable and stable in terms of treating domestic wastewater. Based on the monitoring results of the WWTP, it can be concluded that this system can function in accordance with the planning of the quality of the WWTP outlet which can meet the quality standards of the waste in accordance with  Governor Regulation DKI No. 122 2005.Keywords : Domestic wastewater, process modification, WWTP optimization.

Abstract

Waduk Rio – Rio is an artificial ponds located in East Jakarta. Current condition of the waduk rio - rio is not maintained, its visible from outlet of the ponds foaming indicates pollution. Therefore, monitoring the quality of the ponds which describes the condition of good quality ponds in physics, chemistry, and microbiology. The results of the monitoring and analysis data using the pollution index, it can be seen that the pollution level of Waduk Rio - Rio in the first period (dry season) classified as moderate polluted by pollution index value of 5.542. While in the second period (transitional season), the value of the pollution index at 11.069 and classified as heavy polluted. The pollution sources of Waduk Rio - Rio is domestic wastewater which comes from community activities around the ponds. It can be seen from the high biological parameters such as Fecal Coli and Coliform. In order to reduce the level of pollution in the Waduk Rio - Rio, the domestic wastewater discharged into the ponds needs to be processed first. One of the domestic wastewater treatment technology is a biofilter Anaerobic - Aerobic. Keywords : Pollution Indeks, Water Quality Indeks, Biofilter Anaerob – Aerob

Abstract

Generally, wastewater of nata de coco industry contains suspended solids and COD were high, ranging from 90,000 mg / l. The high level of of the wastewater pollutants, resulting in nata de coco industry can not be directly disposed of its wastewater into the environment agency. Appropriate technology required in order to process the waste water so that the treated water can meet the environmental quality standards that are allowed. Designing the waste water treatment plant that is suitable and efficient for treating industrial wastewater nata de coco is the activated sludge process. Wastewater treatment using activated sludge process of conventional (standard) generally consists of initial sedimentation, aeration and final sedimentation.Keywords : Activated Sludge, Design, IPAL

Abstract

Selection of the appropriate composition desalination units can be done with a variety of method approaches, one of the method is the Analytic Hierarchy Process. In determining the desalination unit with AHP method to consider is setting a goal, an alternative criteria and pairwise comparison. Research for the determination of the exact composition of the desalination unit in order to achieve sustainable drinking water suppy in coastal areas and small islands has been conducted. The results of the study are as follows, the energy demand of 50.83%, operator costs of 26.64%, maintenance costs of 14.13% and chemical requirement 8.4%. For an alternative composition desalination unit of RO 10 m3 / day is the best alternative composition with value of 59.61%, the composition of the next alternative is RO 20 m3/ day of 30.40% and the last alternative of the desalination unit composition is RO 120 m3/ day of 09.99%.Key words : Desalination, Mukti Stage Flash Composition, AHP
