Perencanaan Desain Alternatif IPAL Dengan Teknologi Anaerobic Baffled Reactor Dan Anaerobic Filter Untuk Rumah Susun Romokalisari Surabaya - ITS Repository

Rumah Susun Romokalisari adalah rumah susun yang terletak di kota Surabaya dan berdiri sejak tahun 2015. Walaupun masih termasuk baru, rumah susun ini memiliki beberapa permasalahan dikarenakan tidak adanya pengolahan air limbah grey water yang memadai. Selain itu air buangan dari tangki septik rumah susun yang tidak diolah dapat membahayakan kualitas air tanah di sekitar rumah susun. Oleh karena itu perlu adanya unit pengolahan limbah tambahan untuk mengolah kedua air buangan tersebut. Perencanaan ini memberikan dua alternatif unit yang akan digunakan yaitu Anaerobic Baffled Reactor dan Anaerobic Filter. Kedua unit ini dipilih karena biaya pembangunan dan perawatannya yang murah serta operasionalnya yang mudah, berdasarkan literatur dan penelitian-penelitian sebelumnya.

concentration of 5000mg TOC l-1) and stable methane production, i.e. 0.901 CH4 g-1 of TOC removal, at the early stages of start-up process. The strategy based on maximum substrate loading controlled by reactor pH significantly shortens the start-up regime. In this case, the reactor attained steady state conditions approximately 140 days after start-up. On the other hand, a start-up time of 200 days was required when a strategy based on maximum substrate utilization was adopted. The biomass loss in anaerobic fluidized bed reactor was found independent with respect to start-up of the reactor. The experimental studies (Gorris et al., 1988; Morgan, 1991; Liang et al., 1993; Araki and Harada, 1994) conducted on brewery, synthetic wastewater and ice-cream wastewater evaluated the efficiency of treatment and changing microbial activities, leading to methanogenic biofilm formation during start-up of reactor. The COD removal efficiency reached 85 per cent at volumetric loading of 27- 30kg COD m ±3 day ±1 with methane content up to 72 per cent in the biogas. Upflow velocities (4-25 mh ±1 ) caused a prominent difference in the pattern of initial biofilm formation. Microbial activities with respect to acetate production, hydrogen utilizing and acetate utilizing methanogenesis increased up to 3-4 times as that of suspended growth sludge. A comparative start-up performance of anaerobic reactors including fluidized and expanded bed, was reported (Balaguer et al., 1997) for high strength wastewater at 37 o C and for different support materials.

EFFECT OF ANAEROBIC, Dr. Rostika

EFFECT OF ANAEROBIC, Dr. Rostika

Lack of physical activity leads to increase many health problems. The World Health Organization noted that lack of physical activity is the fourth death factor (6% of deaths worldwide) (WHO, 2010). Based on its metabolism, there are two types of physical activity, aerobic and anaerobic. Aerobic exercise is a physical activity that uses ATP from the oxidative phosphorylation of glycogen and free fatty acids which depends on the availability of oxygen. In contrast, anaerobic exercise uses ATP from glycolysis which no need of oxygen (Astrand et al., 2003).

Intl Conference PEG Wastewater

Intl Conference PEG Wastewater

This paper presents the suitability of anaerobic treatment of PEG-containing wastewater as a pre-treatment in order to recover the potential energy in the form of biogas. Polyethylene glycols (PEGs) are polymers composed of repeating sub-units of identical structure, called monomers, and are the most commercially important polyethers. PEGs are liquid or low-melting solids, depending on their molecular weights. It is prepared by polymerization of ethylene oxide. PEGs are non-toxic and are widely used in the manufacture of cosmetics, water-soluble lubricants, antifreeze agents for automobile radiators, and pharmaceutical, in the conservation treatment of ancient wood and in the production of non-ionic surfactants. Therefore, millions of tons of PEGs are manufactured or involved in industrial processes worldwide every year. Most of them reach conventional wastewater treatment systems after industrial utilization.

Anaerobic Digestion for Energy Production

Anaerobic Digestion for Energy Production

The characteristics of solid wastes determine the successful anaerobic digestion process ( high biogas production potential and degradability). In municipal solid waste, substrate characteristics may vary due to the method of collection, weather season, cultural habits of the community . Substrate characteristics such as its composition, C/N ratio and particle size will be briefly discussed in this sub chapter. The degradability and biogas production potential from solid waste in an anaerobic digester are dependent on the amount of the main components: lipids, proteins, carbohydrates such as cellulose and hemicelluloses as well as lignin (Hartmann and Ahring, 2006). Among them lipids are the most significant substances in the anaerobic digestion, since the methane yield from lipids is higher than from most other organic materials. The theoretical gas yield of glyceride trioleate is, for example, 1.4 m 3 per kilogram of oil with a methane content of 70% (Hanaki , 1981; Angelidaki ., 1990). Although organic waste with a high content of lipids is an attractive substrate for biogas production, Neves (2008) reported that the lowest hydrolysis rate constants were obtained in the assays fed with kitchen waste that contained an excess of lipids. This was presumably due to a synergetic effect on the degradation of the other components since lipids adsorb onto solid surfaces and may delay the hydrolysis process by reducing the accessibility of enzyme attack. Lignocellulosic (cellulose and hemicelluloses which are tightly bound to the lignin) waste can be found in abundant amount in the form of garden waste, paper residue or agricultural waste. Due to the presence of lignin, lignocellulosic waste is considered to be quite resistant to anaerobic digestion and hydrolysis is the rate limiting step in the overall process. In order to improve the rate of enzyme hydrolysis and increase yields of fermentable sugars from cellulose or hemicellulose in lignocellulosic waste, several pretreatment methods such as thermal (steam or hot water), chemical (acid, lime or ammonia addition) or combination of both methods were proposed by several authors (e.g. Mosier ., 2005; Fernandes . 2009).
