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

ABSTRACTSurabaya River is a source of raw water for the needs of the community in Surabaya and its surrounding areas, including for industrial and the Surabaya water supply company. Along with the rapid growth of settlements and the development of the industrial sector, the Surabaya River pollution level has increased so that the quality of the water does not meet the quality standards required as raw water for drinking water. The most potential parameter that causes the level of pollution is organic pollutants. The concentration of some water quality parameters including organic pollutants in the Surabaya River has exceeded class I water quality standards based on Government Regulation (PP) No. 82 of 2001, namely for allotment of raw water for drinking water. The purpose of this study was to improve the raw water quality such as parameters of suspended solids (TSS), organic substances, detergents and manganese (Mn) through the application of biofilter technology. The study was conducted by operating a biofilter pilot plant consisting of a lamella-type settling tank and a biofilter reactor filled with wasp-type nesting media. The results showed that the biofilter process used can reduce the concentration of TSS, organic matter, detergents and Mn in raw water. In general, the longer the hydraulic residence time (HRT) in the biofilter pilot plant, the greater the efficiency of removing TSS, organic matter, and detergent in raw water. The experiments results at the conditions of the shortest total HRT of 81 minutes, including HRT of 36 minutes in the settling tank and HRT of 45 minutes in the biofilter reactor, could obtain TSS removal efficiency of 46.92%, 15.97% for organic matter, and 55% for detergent, where the concentration of these parameters meets the quality standards for drinking water.Keywords: biofiltration, HRT, drinking water, water qualityABSTRAKSungai Surabaya merupakan sumber air baku untuk kebutuhan masyarakat di wilayah Surabaya dan sekitarnya, termasuk untuk kebutuhan industri dan air baku PDAM kota Surabaya. Seiring pesatnya pertumbuhan pemukiman dan perkembangan sektor industri, mengakibatkan tingkat pencemaran Sungai Surabaya semakin tinggi sehingga kualitas airnya tidak memenuhi ketentuan baku mutu yang dipersyaratkan sebagai air baku air minum. Parameter yang paling potensial menyebabkan tingkat pencemaran tersebut adalah polutan organik. Konsentrasi beberapa parameter kualitas air termasuk polutan organik di sungai Surabaya telah melebihi baku mutu air kelas I berdasarkan Peraturan Pemerintah (PP) No 82 tahun 2001, yakni untuk peruntukan air baku air minum. Tujuan dari penelitian ini adalah untuk melakukan peningkatan kualitas air baku seperti parameter padatan tersuspensi (TSS), zat organik, deterjen dan mangan (Mn) melalui penerapan teknologi biofilter. Penelitian dilakukan dengan mengoperasikan pilot plant biofilter yang terdiri dari bak pengendap tipe lamella dan reaktor biofilter yang diisi dengan media plastik tipe sarang tawon. Hasil penelitian menujukkan bahwa proses biofilter yang digunakan dapat menurunkan konsentrasi TSS, zat organik, deterjen dan Mn di dalam air baku. Secara umum semakin lama waktu tinggal di dalam pilot plant biofilter, efisiensi penghilangan TSS, zat organik, dan deterjen di dalam air baku semakin besar. Hasil percobaan pada kondisi total waktu tinggal terpendek (total HRT) 81 menit, meliputi HRT di bak pengendap 36 menit dan HRT di reaktor biofilter 45 menit, didapatkan efisensi penghilangan TSS 46,92 %, zat organik 15,97 %, dan deterjen 55 %, dimana konsentrasi parameter-parameter tersebut memenuhi baku mutu untuk air minum.Kata kunci: biofiltrasi, HRT, air minum, kualitas air

Abstract

Water disinfection means the removal, deactivation or killing of pathogenic microorganisms. Microorganisms are destroyed or deactivated, resulting in termination of growth and reproduction. When microorganisms are not removed from drinking water, drinking water usage will cause people to fall ill. Chemical inactivation of microbiological contamination in natural or untreated water is usually one of the final steps to reduce pathogenic microorganisms in drinking water. Combinations of water purification steps (oxidation, coagulation, settling, disinfection, and filtration) cause (drinking) water to be safe after production. As an extra measure many countries apply a second disinfection step at the end of the water purification process, in order to protect the water from microbiological contamination in the water distribution system. Usually one uses a different kind of disinfectant from the one earlier in the process, during this disinfection process. The secondary disinfection makes sure that bacteria will not multiply in the water during distribution. This paper describes several technique of disinfection process for drinking water treatment. Disinfection can be attained by means of physical or chemical disinfectants. The agents also remove organic contaminants from water, which serve as nutrients or shelters for microorganisms. Disinfectants should not only kill microorganisms. Disinfectants must also have a residual effect, which means that they remain active in the water after disinfection. For chemical disinfection of water the following disinfectants can be used such as Chlorine (Cl2),  Hypo chlorite (OCl-), Chloramines, Chlorine dioxide (ClO2), Ozone (O3), Hydrogen peroxide etch. For physical disinfection of water the following disinfectants can be used is Ultraviolet light (UV). Every technique has its specific advantages and and disadvantages its own application area sucs as environmentally friendly, disinfection byproducts, effectivity, investment, operational costs etc. Kata Kunci : Disinfeksi, bakteria, virus, air minum, khlor, hip khlorit, khloramine, khlor dioksida, ozon, UV.

Abstract

The treatment process of wastewater contains organic pollutant which used in Indonesia especially in Jakarta is generaly activated sludge process. The problem is its treated water quality which frequently does not yet fulfilled to effluent standard of wastewater. Some affecting factors  are hydraulic retention time (HRT) too short, the fluctuation of wastewater flow rate, unfavorable function of aeration process and also which do not less important is operational mistake caused by insufficient knowledge of operator. To overcome the mentioned problems it is needed technological innovation to increase efficiency of wastewater treatment process especially activated sludge process. Moving Bed Biofilm Reactor (MBBR) technology is one of the  effective alternative for treating wastewater containing organic pollutants. In principle, MBBR is a modification of the activated sludge process is enhanced by adding the media into the aeration tank.This paper describes the study of domestic waste water treatment  using MBBR process which is filled with bioball plastic media which has specific surface 210 m2/m3 as much as 20 % of the volume of the aeration tank for attaching microorganism to increase efficiency and  keep stability of process.Result of the study shows that within 12 hours, 8 hours, 6 hours and 4 hours of hydraulic retention time (HRT) in aeration tank and sludge circulation ratio 0f R = 1.0 Q, the removal efficiency of ammonia were 94.05 %, 93.42 %, 89 %, and 79.6 % respectively. In ammonia loading 0.106 – 0.302 kg/m3.day, the removal efficiency of ammonia were 95.54 – 83.01 %. The greater ammonia loading,  removal efficiency of  ammonia  is getting smaller. Optimal residence time is 6 hours with ammonia removal efficiency reached 89 %, and the average concentration of ammonia in the effluent of 8.3 mg per litre.  Keyword : Domestic wastewater, ammonia, bioball, MBBR.

Abstract

In line with fast growth of populations in urban area the discharged waste water from daily activities have caused contamination of ground water and also surface water. Unbalance between distribution of source and usage of water have caused unbalance between supply and demand. Therefore, new innovation in the case supply of raw water has come to important attention. One of the alternatives which getting much attention in many state in world is to use recycle wastewater especially municipal wastewater as one source of raw water for water supplySeveral things which need to be paid attention in the case of usage of recycle wastewater are consistency of the treated water quality as according to enabled condition. In usage of recycle wastewater to be used as clean water supply there is several categorize of contaminant which must be paid attention peculiarly namely for example organic contaminant including pesticide, pathogenic bacteria, parasite, virus and also heavy metal contaminant for example mercury, lead, chrome, cadmium etc. Therefore the treatment process must be done neglectlessly with control of quality which able to be justified.One of the concept for processing of urban wastewater to be made clean water is use combination of primary treatment, secondary treatment with biological process continued by advanced treatment by physico-chemical process for example covering clarification process, nutrient removal, recarbonation, filtration, adsorption with activated carbon, ion exchange process, and also demineralization with process of reverse osmosis and also ozonization and chlorination. With these processes combination can treat wastewater yield treated water with quality of as drinking water.This paper explained some example of wastewater treatment process for recycle wastewater which have been applicated in some state. One of the example of wastewater recycle process using combination of biological process continued with ultra filtration process, reverse osmosis process, and disinfection by ultraviolet, and also pH control such as those which have been conducted by NEWATER Factory, Singapore. Kata Kunci : Daur ulang, air limbah, teknologi, lingkungan.

Abstract

Activated carbon is substance or material which is often used in processing of drinking water to eliminate such's pollutant for example : organic matter, odors, ammonia, detergent, phenol compound, organic compound of methane derivates, and others substances, which cannot be eliminated by usual processing like coagulation, flocculation, precipitation and filtration. The processing of drinking water using Powder Activated Carbon (PAC), influenced by  water flow rate, concentration of pollutant to be eliminated, injection rate of activated carbon, contact time as well as influenced by type of process for example single stage operation or multi stage operation either through cross current operation or with countercurrent operation. Despitefully is also influenced by nature of activated carbon it's self. Processing of drinking water using powder activated carbon very compatible and economic for processing in a state of emergency for example at the time of dry season where quality of water become worse, because its can be conducted as according to existing equipments without making special equipments.Kata Kunci : Pengolahan, air minum, karbon aktif bubuk.

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

A rotating biological contactor (or RBC) is a type of fixed media filter which removes both organic matter and ammonia from water.  It can be added to a packaged plant for more efficient ammonia removal, replacing the aerator in both location and function.The RBC consists of a series of rotating discs.  These discs are coated with a biological slime like the slime on rocks in a healthy stream.  This slime is rotated through the air and and then through the wastewater so that it picks up oxygen in the air and breaks down B.O.D. in the wastewater.  Since the discs rotate through the air, there is no need to pump air into the wastewater.  And since the slime stays on the discs, there is no need to recycle sludge. The present study describes basic consideration of rotating biological contactor (RBC) system for wastewater treatment. The design of an RBC system must include the following consideration sach as organics  and surface loading criteria, staging of RBC units, peripheral velocity, temperature, effluent characteritics and secondary clarifier. The RBC system have some advantages : smaller basin, less upset, high loading rate, nitrification/de-nitrification, high tolerance, low O&M Cost, durable constructions, odorless, no noise, and stable sludge characteristics. Kata Kunci : Reaktor bioloigis putar, air limbah, parameter disain.
