Abstract

Industri Nata de Coco merupakan merupakan salah satu agroindustri yang dalam proses produksinya menghasilkan air limbah yang bersifat asam dan mengandung konsentrasi polutan organik yang tinggi, terutama air limbah yang berasal dari sisa fermentasi nata. Oleh karena itu, air limbah tersebut harus diolah dengan baik agar tidak mencemari lingkungan. Berdasarkan Peraturan Menteri Lingkungan Hidup Republik Indonesia Nomor 5 Tahun 2014 Tentang Baku Mutu Air Limbah, baku mutu air limbah industri Nata de Coco yang boleh dibuang ke badan air atau saluran umum yakni dengan konsentrasi maksimum COD 150 mg/l, BOD 75 mg/l, TSS 100 mg/l dan pH 6-9. Tujuan penelitian ini adalah melakukan uji kinerja pengolahan air limbah industri Nata de Coco yang berlokasi di Gunung Putri, Kabupaten Bogor, menggunakan proses lumpur aktif. Penelitian dilakukan mulai bulan Februari sampai dengan bulan April 2019. Dari hasil penelitian dapat diketahui bahwa air limbah industri Nata de Coco mempunyai pH yang rendah dengan konsentrasi zat organik (COD) yang tinggi, dapat mencapai lebih dari 5000 mg/l. Perbandingan BOD/COD air limbah berkisar 0,34 sehingga relatif sulit untuk terurai secara biologis. Untuk mengolahan air limbah industri Nata de Coco dengan menggunakan proses lumpur aktif, pH air perlu dinaikan menjadi sekitar 8 agar proses lumpur aktif berjalan optimal. Hasil penelitian menunjukkan bahwa dengan beban COD rata-rata 0,56 kg COD/m3.hari didapatkan efisiensi rata-rata penghilangan COD sebesar 95,7 %. Kata Kunci: Air Limbah, Nata de Coco, Lumpur Aktif

Abstract

Sumber air minum daerah padat penduduk dan masyarakat pesisir dipenuhi dari air permukaan atau sumur dalam. Air permukaan dipengaruhi oleh pasang air air laut , sehingga hampir sepanjang  waktu dalam setahun kualitas airnya payau bahkan asin. Disamping konsentrasi garam yang tinggi, kualitas air sumur dalam juga buruk yaitu mengandung zat organik, besi dan mangan tinggi, hal ini disebabkan oleh struktur tanah dan sanitasi lingkungan yang buruk dari masyarakat nelayan. Penggunaan air hujan sebagai sumber air alternatif dalam pemecahan masalah tersebut, terbatas untuk memenuhi kebutuhan air minum di musim penghujan. Alternatif lain, masyarakat harus mencari dari daerah lain yang jauh dari rumah mereka atau membeli air dengan harga mahal. Untuk memecahkan masalah kritis ini diperlukan penerapan teknologi pengolahan air yang sesuai. Teknologi pengolahan air ini harus menghasilkan air minum yang memenuhi standar teknis dan teknologi yang aplikatif, mudah dan murah dalam operasi dan pemeliharaan karena diharapkan masyarakat di daerah itu dapat mengelola, mengoperasikan dan maintenace. Teknologi osmosa balik untuk mengolah air asin menjadi air minum merupakan salah satu alternatif untuk memenuhi kebutuhan air minum yang memenuhi syarat teknis kesehatan dan hasil pengelolaannya dapat meningkatkan derajad sosial maupun ekonomi masyarakat nelayan.Kata kunci : air minum, air asin, masyarakat pesisir, osmosa balik, padat penduduk

Abstract

Until now, the drinking water companies in Indonesia still use chlorine for disinfection processes. In addition, the chlorine also uses for removal Fe, Mn and ammonia. If the raw water contains high concentration of ammonia, chlorine will react with ammonia form chloramines which have lower strength of disinfection power. The higher concentration of ammonia in raw water caused the higher consumption of chlorine. The reaction of chlorine with certain organic compounds as humic substances will to produce chloro-organo compounds like chlorophenols which become serious problems to day because trihalomethane and also chlorophenols compounds are carcinogenic substances.To overcome the problems one of alternative is using the combination of biofiltration and ultrafiltration to process the drinking water. Biofltrations process is treatment of raw water biologically using fixed bed biofilter reactor witch filled with honeycomb plastic supporting media for removal Fe, Mn, ammonia detergent, and also organic substances. Ultrafiltration (UF) is filtration process using hollow fiber membranes that have effective pore sizes of 0.1 – 0.01 µm. The ultrafiltration units are capable of separating some large molecular weight dissolved organics, colloids, macromolecules and suspended solids from raw water. The ultrafiltration process is designed to remove colloidalized particles in the range from 0.1-0.01µm.By combining the biofiltration and ultrafiltration processes, hence will be got technological alternative of drinking water process which capable to degrade an organic matter, ammonia, detergent and can remove the colloidal or suspended matter effectively without chemicals instead of conventional process. Kata Kunci : Pengolahan Air Minum, Biofiltrasi, Membran, Ultrafiltrasi, Pilot Plant

Abstract

Kepulauan seribu (Seribu Archipelago) is one of region of north jakarta, the province of DKI Jakarta Raya which is populated by around 18.000 inhabitants. It consists of 111 small islands. Among them, there are about 11 (eleven) islands are stated as the residential:   P. Untung Jawa, P. Tidung Besar, P. Lancang Besar, P. Panggang, P. Pramuka, P. Kelapa I, P. Kelapa II, P. Harapan, P. Sebira. P. Payung dan P. Pari. P. Panggang and P. Kelapa I are the most populated.In relation to the clean water supply, specifically for drinking water/freshwater, mostly is got from the narrow well, rainfall and some water treatment installations that heve been owned by some islands. However, problem arises when the prolong dry season comes as the quality of water in the narrow well decreases significantly, the well water became brackish. In order to cope this problem, the avaibility of sufficient water treatment installations to process brackish water into freshwater is very important. The water treatment installation with reverse osmosis system is one of the most effective alternative in order to provide the freshwater for the people in the islands. The system has also been aplied sufficiently in several islands, such as P. Kelapa I, P. Tidung, P. Pramuka, P. Untung Jawa, P. Panggang dan P.

Abstract

One of common problem on dense settlement area in Indonesia is the need for clean water and especially at rural and isolated areas this problem have not been properly solved yet. The ground and river water which consume by the community do not meet the requirement for drinking water, even at several places the water is not suitable to drink. The standard requirement for drinking water have to comply with the physical, chemical and biological requirements and if one parameter do not comply with the requirement then the water is not proper to drink.Most of residential area in Indonesia have poor water quality and have not got clean water services from local PAM, therefore in order to fulfill the need for drinking water, the community buy bottled drinking water which is very expensive.To overcome the above problem, a pilot  unit package of technology have been developed, to treat well water or clean water from PAM to be direct to drink water ( no need to boiled it ). The unit consists of water pump, sand filter, mangan zeolit filter, activated carbon filter, cartridge filter, ultra violet sterilisator and ozon generator Kata Kunci : Air tanah, air PAM, pengolahan air,  air siap minum

Abstract

In big cities, the water quality of rivers used as the main raw water sources is getting worse and worse. That is caused by a lot of improper wastewater management systems, especially in industrial and settlement areas. As an example, the raw water of PDAM TKR Bojong Renged which is taken from Cisadane  Rives contains Ammonia 3.8 mg/l and it means that the content is not allowed to be used as the raw water for drinking water purpose. To cope with the problem, a bofiltration process can be used as one alternative to reduce Ammonia till the required standard quality.  A honeycomb tube type made plastic was the media of biofilter reactor. Operational condition was varied with HRT (Hydrolysis Retention Time) between 1-4 hours and air supply between 0-30 l/minute. The best process condition was found at 2 hour-HRT and 20 l/minute air supply and the Ammonia removal efficiency was about 65%. The linear regression equation was  ya  = -91.19xa + 77.12, where Y is for removal efficiency and the axis X is for Ammonia loading.  Keywords:  raw  water quality, ammonia, biofiltration, honeycomb tube, removal efficiency,
