Abstract

Instalasi pengolahan air minum (IPA) Taman Kota, Jakarta Barat, memiliki kapasitas disain 200 liter/detik, dan air baku berasal dari Cengkareng Drain dan terdapat unit prasedimentasi sebelum air baku masuk ke IPA. Digunakan IPA konvensional yang dilengkapi dengan unit bio filter untuk mengabsorbsi zat organik di air baku. Lumpur berasal dari unit sedimentasi yang dibuang secara rutin setiap 10 menit dengan volume lumpur rerata 144,93 m3/hari dan pada kondisi maksimum 628,30 m3/hari, unit biofilter yang dibuang secara berkala saat dilakukan pengurasan bak yaitu 150,10 m3/hari, serta unit saringan pasir cepat yang membuang air bekas backwash filter secara berkala dan dalam waktu yang singkat sebesar 468,86 m3/hari. Mempertimbangkan perbedaan karakteristik lumpur yang dihasilkan, direncanakan 2 unit tanki penampung (ekualisasi) terpisah yaitu tanki pertama menerima lumpur sedimentasi serta tanki kedua menerima lumpur pengurasan bio filter dan air bekas backwash filter. Memperhatikan luas lahan yang tersedia, maka lumpur sedimentasi yang terkumpul di tanki penampung dipompa menuju ke unit thickener dan selanjutnya ke unit dewatering mekanik. Studi perbandingan dilakukan terhadap 3 opsi peralatan dewatering mekanik dengan mempertimbangkan volume lumpur yang dapat direduksi, biaya investasi, serta biaya operasional dan energi.   Peralatan dewatering mekanik terpilih adalah belt filter press yang mereduksi lumpur sedimentasi menjadi 4,20 m3/hari, dan pada kondisi maksimum menjadi 18,20 m3/hari. Keywords: water treatment plant, sludges, backwashed water, dewatering

Abstract

Aim: This study is to determine effect of contamination level of population settlement activity on water quality in the reservoir at west Sunter by measurements of reservoir water quality in the form of physical and chemical parameters including the identification of the kinetics of COD. Methodology and Result:  This research was conducted in April to August 2016 with 11 sampling locations. Research indicated that the reservoir had experienced heavy pollution with DO value ranging between 1.05 mg/L-1.52 mg/L with a minimum quality standard of 3 mg/L, Ammonia 0.13 mg/L-0.38 mg/L with a quality standard of 0.02 mg/L, surfactant (1.74 mg/L-4.63 mg/L) quality standard of 0.2 mg/L and phosphate (0.8 mg/L-1:19 mg/L) to the quality standard of 1 mg/L. Reservoir also were polluted with heavy loads inclusion of organic content with COD values ranging between 112.58 mg/L - 196.39 mg/L. The source of pollution in the west Sunter reservoir was derived from domestic sewage. Based on the average constant value it takes 16.96 hours to reduce the COD from 120 mg/L to 40 mg/L. Natural Retention time at West Sunter Reservoir is 13.6 days. Conclusion, significance and impact study: Domestic waste has obviously contaminated West Sunter reservoir from its physically green color, high organic content with high COD values, low DO, high oil and fat content, and high phosphate levels. These polluted compounds must be removed before spreading to the next water body. If the reservoir is considered as a reactor site, then the reservoir must be able to remove the contaminants before disposal.

Abstract

Aim:This research is  aimed  to study of organic degradation in  Pluit reservoir,  that located in the Village Penjaringan, North Jakarta, between 6° 07' 28.6" S 106° 48' 07.6" E and 6° 06' 40.2" S 106° 47'51.1"E with a broad area of ± 80 Ha, depth 1-8 meter. Flow systems pluit reservoir is half continuous and water is disposed with 4 units pump with a capacity of 4.5 m3/s which operates 8 hours/day throughout 11 pumps available. From the results of research findings are then compared with quality standards inspection according to the Government Regulation No. 82/2001 Class II for a review of recreation, fisheries and agriculture. Methodology and Result:The 90% of the DO value is ≤ 2 mg/L. The phosphate value obtained overall is not complied to the standard quality (≤ 0.2 mg/L P). In Pluit reservoir is found organic compounds as raw CODwhich was not complied to the standard quality (≤25 mg/L COD) approximately 27.52 mg/L COD - 371.52 mg/L COD. A kinetics test was done in order to determine the decreasing rate of COD in two conditions, where the first aeration to initial DO reached 4.5 mg/L, and the second is without aeration. Conclusion, significance and impact study:The COD degradation towards time is then measured and shows that organic degradation rate towards time without aeration process shows no decreasing, while non-aerated condition shows that the reaction rate following first pseudo reaction is 0.096 hours-1 – 0.133 hours-1 with an average value of 0.1177 hours-1.
