Abstract

Industri yang mengeluarkan limbah amoniak merupakan jenis industri yangcukup banyak keberadaannya di Indonesia, oleh sebab itu suatu penelitian dan pengkajian pengolahan limbah amoniak akan bermanfaat untuk memberi masukan pada pihak pemerintah maupun pihak industri dalam menjaga kelestarian liangkungan perairan. Penelitian dan pengkajian pengolahan limbah amoniak konsentrasi tinggi telah dilakukan dengan cara biologis menggunakan reaktor biofilter tercelup. Pemilihan sistem ini karena telah diketahui cara biologis adalah cara yang paling ekonomis dan reaktor biofilter tercelup merupakan sistem yang mudah dioperasikan dengan hasil yang cukup optimal. Pengolahan limbah amoniak dilaksanakan melalui dua proses yaitu proses nitrifikasi dan proses denitrifikasi. Pada percobaan terdahulu telah dilakukan percobaan penurunan amonia dengan proses nitrifikasi dan berhasil baik, dan percobaan kali ini prosesnya adalah denitrifikasi. Proses denitrifikasi bertujuan untuk menghilangkan senyawa nitrit dan nitrat, sehingga pada akhirnya hasil olahan air limbah yang keluar telah bebas dari senyawa nitrat dan selanjutnya dapat dibuang ke perairan umum. Hasil percobaan proses denitrifikasi menghasilkan penurunan rata-rata nitrit 100% dan nitrat 99%, dengan volume reaktor 45 liter, kapasitas maximum 4,8 liter/jam dan waktu tinggal 72 jam. Kemampuan optimal biofilter dalam menurunkan nitrat adalah 5351 mg/liter/m3 media biofilter, dengan waktu tinggal optimal 3 hari.

Abstract

Wastewater treatment of a combined anaerobic-aerobic system is secondarywastewater treatment after physical treatment. Basically this wastewater treatment relies on bacteria in degrading pollutants. The use of honeycomb biofilter is to increase specific surface of media for attaching bacteria. Total volume of reactors is 280 liter, made of glass, equipped with two circulating pump and blower in the aerobic zone. The Biofilter is made of plastic, structurally like honeycomb. Its dimension is 28 cm x 25 cm x 30 cm, very light and easy to clean. It takes 14 days for seeding.The reactors were run in four different resident time, namely 7 days, 5 days, 3 days and 1 day. The raw water used in this experiment is wastewater from tofu and fermented soybean cake industries that have BOD around 300 - 500 mg/l. The water is sampled weekly and the results from 1,872 physical and chemical parameters from 144 water samples show that the reactors that using biofilters have better performance than the reactors using no biofilters. The Efficiency process in decreasing BOD value is around 51 - 91 % for resident time one day up to 7 days. Besides such a good relatively high efficiency, the hydraulic loading is around 0,48 - 3,33 m3/m2/ day and BOD loading is around 0, 20 - 0,43 kg BOD/m3/day.

Abstract

Waste to energy now become one of the technology solution that is in many developed  countries, in an effort to reduce greenhouse gas emissions from waste. Urban organic waste is a potential source of greenhouse gases. Methane gas is an energy source that can be used as fuel. It is difficult to find land for Landfill alocation in the major cities and often becomes a difficult social problem. Structured Landfill Cell is used to treat the waste at the landfill, with the aim to use land more scalable, easier waste management and control, better sanitation, better water control leachate and gas produced can bemanaged optimally and compost can be utilized with the production and quality control.This new system was first used in Indonesia by PT Navigats Organics Energy Indonesia in landfill Suwung, Denpasar, Bali. There are 5 cells already built in Suwung and two of cells have been filled with garbage. Each cell contains 12,000 m3 soliswaste. Observations carried out on gas productivity of two cells that have been filled, with a dry treatment on cell 1 (dry cell) and a wet treatment in cell 2 (wet cell). The observed gas is CH4, CO2,and O2 as the main parameters, with the addition parameters are CO and H2S. The instrument used is the GA 2000 Plus. Observations of two cells made for 4 months, with the content of CH4 around 40 to 50% in the first month and gradually decreased to reach 18 to 25% in the fourth month. Carbondioxyde going up and down following condition of CH4 and its value ranges between 16 and 28%. Oxygen consentration around 2 to 14%.For keeping engine performance the consentration of methane should more than 28%and O2 content lower than 6%. Cell with watering will temporarily reduce CH4 and CO2 and O2 increase, but it is slowly rising again. Carbonmonoside values tend to increase with age garbage (10 sd 350 ppm), whereas irregular H2S values ranging 0 up to 24 ppm, allegedly associated with the low protein content in the trash. Sewage treatment system is proven to increase CH4 gas, yet still needed modifications of structure and the gas collector pipe system so that productivity can be improved.Key Words : Solidwaste, Metana, Cell System

Abstract

The rapid growth of population in developing country causes environmental contamination by increasing significantly pollution load in  river and other water body. It needs efficient and effective strategy to overcome contamination in certain areas. Technical identification of pollution source and its influence to environmental quality is important to should be known and socialized to community. Land use to is important to get  priority  and should be  managed consistently environmentally sound, beside solid waste and domestic wastewater. Law enforcement also should be applied, especially to company or industry which significantly gives contribution to environmental degradation. Environmental restoration need fund, so government as regulator need partner  from private to overcome environmental problem. Environmentally based industries and services is needed to be developed as government counterpart, but up to now the development of them retarded caused by non competitive interest of commercial bank. Environmental fund should be collected from polluter through regulated mechanism and In the next future  environmental bank should possible manage the fund and finance environmental industry and services to overcome environmental pollution, in this case government act as regulator only.Key words : water polution, management, water resources, strategies

Abstract

Biofilter as one of method processing of waste have been introduced since early 20, but in its application have time to be left by effect of newer technological appearance like trickling filter, rotating biological contactor, activated sludge, and fluidized bed reactor. Biofilter very effective in deodorizing, especially dangerous aromas of organic volatile compound, and poisonous air from industry with efficiency 90 - 99,9%. Biofiltrasion become more economic compared to carbon adsorption or oxidation when its organic content under 3000 ppm. Most biofilter operate on organic concentration around 1000 ppm or  lower. There are some matter to influence market of biofilter, for example :        1). the increasing of regulation about oxide nitrogen emission coming from hot process. Biofilter do not yield nitrogen oxide addition, 2). The increasing of sigh of society about contamination of aroma of facility processing of waste, processing of solid waste and others, 3). preventive methodologies implementation of pollution using condensation and air emission concentration, 4). Pressure to industry to use processes with discard as small as possible, 5). The increasing of attention to emission of hit and organic air materials, and also low cost water treatment technology.   Kata Kunci  : Bau, Odour, Biofilter, Biofilm, Limbah tahu dan tempe, wastewater treatment
