Domestic Wastewater Treatment

ABSTRAK Di Indonesia, operasional penambangan batubara umumnya melibatkan tenaga kerja dengan jumlah yang besar. Kondisi ini memberikan tantangan tersendiri dalam pengelolaan dampak lingkungan yang berpotensi timbul dari aktivitas manusia. Salah satu potensi tersebut yakni air limbah domestik. Air limbah domestik merupakan air limbah yang berasal dari aktivitas hidup sehari-hari manusia yang berhubungan dengan pemakaian air. Di area operasional pertambangan, air limbah domestik dapat timbul dari area pemukiman karyawan dan perkantoran. Karena potensi dampaknya terhadap lingkungan, air limbah domestik harus diolah sebelum dialirkan ke badan air penerima. Sejak tahun 1990an, diawal operasi penambangan, Kaltim Prima Coal (KPC) telah membangun dan mengoperasiokan Instalasi Pengolahan Air Limbah Domestik (IPALD) untuk mengolah air limbah domestik yang bersumber dari pemukiman karyawan dan perkantoran. Terdapat 12 IPALD dengan teknologi lumpur aktif yang beroperasi di area KPC. Lumpur aktif merupakan salah satu teknologi pengolahan air limbah domestik dengan memanfaatkan peran bakteri aerob untuk mendegradasi material organik yang terkandung didalam air limbah domestik. Makalah ini disajikan untuk mendeskripsikan performa teknologi lumpur aktif yang digunakan dalam IPALD KPC dan tantangan yang dihadapi dalam pengoperasiannya. Salah satu tantangan yang dihadapi yakni pemenuhan baku mutu yang tertuang dalam Keputusan Menteri Lingkungan Hidup dan Kehutanan No. P. 68 Tahun 2016 tentang Baku Mutu Air Limbah Domestik. Baku mutu terbaru mengatur konsentrasi efluen IPALD lebih ketat dari sebelumnya dan terdapat paramater baru, diantaranya amoniak yang memerlukan perhatian dalam pengoperasian IPALD. Kata kunci: air limbah domestik, lumpur aktif, ipald  ABSTRACT In Indonesia, coal mining operations generally involve a huge number of workers. This condition causes its own challenges in managing environmental impacts that potentially generated from human activities. One of them is domestic wastewater. Domestic waste water is waste water that comes from activities of daily living of humans related to water usage. In mining operations, domestic wastewater is generated from office and residential areas. Because of the potential impact on the environment, domestic wastewater must be treated before flowing to natural water bodies. Since the beginning of mining operations in 1990s, PT Kaltim Prima Coal has been building and operating Domestic Wastewater Treatment Plant (IPALD) to treat domestic wastewater resulting from offices and residential areas. There are 12 IPALDs with activated sludge technology operating in the KPC area. Active sludge is one of the domestic wastewater treatment technologies by utilizing the role of aerobic bacteria to degrade organic material contained in domestic wastewater. This paper is presented to describe the performance of activated sludge technology used in the KPC’s IPALD and the challenges faced in its operation. One of the challenges faced is the fulfillment of water quality standards in Minister of Environment and Forestry Decree No. P. 68 of 2016 concerning Domestic Wastewater Quality Standards. The latest quality standards regulate the effluent concentration of IPALD more stringent than before and there are new parameters, including ammonia which requires attention in the operation of IPALD. Keywords: domestic waste water, activated sludge, ipald

Domestic Wastewater Treatment

In Indonesia, coal mining operations generally involve a huge number of workers. This condition causes its own challenges in managing environmental impacts that potentially generated from human activities. One of them is domestic wastewater. Domestic waste water is waste water that comes from activities of daily living of humans related to water usage. In mining operations, domestic wastewater is generated from office and residential areas. Because of the potential impact on the environment, domestic wastewater must be treated before flowing to natural water bodies. Since the beginning of mining operations in 1990s, PT Kaltim Prima Coal has been building and operating Domestic Wastewater Treatment Plant (IPALD) to treat domestic wastewater resulting from offices and residential areas. There are 12 IPALDs with activated sludge technology operating in the PT KPC area. Active sludge is one of the domestic wastewater treatment technologies by utilizing the role of aerobic bacteria to degrade organic material contained in domestic wastewater. This paper is presented to describe the performance of activated sludge technology usedin the KPC’s IPALD and the challenges faced in its operation. One of the challenges faced is the fulfillment of water quality standards in Minister of Environment and Forestry Decree No. P. 68 of 2016 concerning Domestic Wastewater Quality Standards. The latest quality standards regulate the effluent concentration of IPALD more stringent than before and there are new parameters, including ammonia which requires attention in the operation of IPALD.

Domestic wastewater from non toilets is referred to as grey wastewater, domestic wastewater from bathing, washing and from the kitchen. Incubator Bisnis (INBIS) Permata Bunda is a forum for the application of entrepreneurial skills (apprenticeship) for people with disabilities residing in Kampung Aren, Bontang City, East Kalimantan. Grey wastewater treatment at INBIS Permata Bunda with a grease trap, filtration, sedimentation, anaerobic biofilter, aerobic biofilter, sedimentation and control. The research objective was to determine the effectiveness of INBIS Domestic WWTP to reduce organic pollutant loads based on the quality standard parameters of domestic wastewater from the Minister of Environment and Forestry Regulation No.P.68 of 2016 those are the parameters of pH, BOD, COD, TSS, fatty oil, ammonia, and total coliform. The domestic wastewater treatment process for grey wastewater has a reduced effectiveness ranging from 56.73% - 97.65% and has met the quality standards for the parameters, pH, BOD, COD, ammonia, fatty oil, and total coliform, but for TSS parameters and total coliform needs operational evaluation. Grey waterwater from the INBIS domestic wastewater treatment plant has the potential to become an alternative water source for watering plants (afforestation) if the processing results are in accordance with quality standards.

Polyphosphate Accumulating Organisms

To meet the effluent requirements given for the sensitive receiving body, the Southpest Wastewater Treatment Plant of Budapest, Hungary uses a combined activated sludge-biofilter system with chemical precipitation for P removal. Causes of the proliferation of glycogen accumulating organisms (GAOs) observed in the unaerated/oxic activated sludge unit of this system were investigated both in full-scale and in lab-scale experiments combined with a detailed analysis of the microbial communities. Concentration profile measurements throughout the 8-stage activated sludge unit indicated anaerobic conditions in the first two unaerated reactors and low orthophosphate level (<1 mg l−1) in all of the stages that could not be attributed to the influent quality, but to Fe (III)-dosing to the returned activated sludge. Microbiological analysis revealed the presence of GAOs from the GB group in the Gammaproteobacteria and occasionally tetrad-forming organisms from Actinobacteria, and the absence of Rhodocyclus-related polyphosphate accumulating organisms (PAOs) in the activated sludge samples. Comparative lab-scale studies carried out in two identically arranged UCT-systems with staged anoxic reactors also confirmed that Fe (III)-dosing may result in phosphorus deficiency of the microbial niche, leading to the suppression of growth and EBPR activity of PAOs and to the proliferation of GAOs.

Domestic Wastewater Treatment

Crepe cotton bandages (textile fabrics) are common household kit in the medical first aid boxes and are globally used in pharmaceutical and health care units to offer heat, insulation and support in many medical situations. Southern Tamilnadu comprises of more than 150 crepe bandage textile units and exports tonnes of crepe cottons. Many units are operated on continuous basis and therefore the amount of wastewater generated and its treatment is of critical importance. Unlike typical textile effluent, crepe cotton processing wastewater do not contain dyes, but significant proportions of caustic soda, soda ash, bleaching agents and COD. This paper discusses the effluent treatment of crepe cotton processing units using mixed cultures of macroalgae and activated sludge microbes. There are very few studies comparing the performance of activated sludge and macro algae in wastewater treatment. Fresh water macroalgae was collected from a nearby pond and activated sludge was collected from the aeration basin of domestic wastewater treatment plant. Crepe cotton processing effluent had significant concentrations of COD, TDS, TSS and was highly alkaline. The COD removal efficiency of about 73.8% and 99 % was obtained for macroalgae and activated sludge microbes respectively. COD removal was quick in activated sludge while macroalgae cultures took 144 h to remove 275 mg/L of COD. This study shows that activated sludge microbes are quick to adapt in uptake of organics from crepe cotton effluent when compared to macroalgal sp, further studies will provide insights on generating bioenergy from algal species grown in crepe cotton effluent for sustained plant operation.

Wastewater Quality

Domestic wastewater treatment is one of the environmental problems in Surabaya. Besides causing water pollution, wastewater also causeing health problems. A method to treat wastewater is Communal Waste Water Treatment Plant (WWTP). The effluent of WWTP is then reused by residents. The study aimed to describe the WWTP in Kelurahan Simokerto, Kecamatan Simokerto, Kota Surabaya, and compare wastewater parameters to the regulation. The study is a descriptive observational and cross-sectional research. The method used is interview with WWTP organizer and laboratory examination on 5 samples of influent and effluent parameters include pH, BOD, COD, TSS, oil and grease. All of influent and effluent parameters have already met domestic wastewater quality standards in Peraturan Gubernur Jawa Timur No. 72 Tahun 2013 so the effluent is safe to be discharged into the environment. Since the influent and effluent is below the maximum level of quality standards, the Communal WWTP in Kelurahan Simokerto hasn’t already met standard for an appropriate WWTP. The experts need to do study about wastewater characteristics before building a WWTP so that the appropriate WWTP is obtainable. Moreover, they need to do in-depth study about factors that affect wastewater quality. It’s necessary to arrange detailed SOP for routine operations and maintenance of WWTP accompanied by improvement of understanding of the organizer and citizens about the importance of communal WWTP as well as how to operate and maintain.

Abstract. Domestic wastewater (toilet water and household water from kitchens) is evacuated in unit or separate networks to the purification station (STEP) in order to eliminate their waste; organic and mineral matter, dissolved and suspended before discharging them into the natural environment or reusing them in irrigation. The main purpose of this work is to operate the wastewater treatment plant in the Ben Slimane Airport area by using activated sludge, this process consists of destroying pollutants and microorganisms by bacteria formed in the clarifier. Moreover, the operation of the station was considered by controlling the sensors installed in each basin to promote their optimization, in addition, the physicochemical analysis was carried out in the STEP laboratory. The results found for the parameters studied showed the very effective reduction of the organic load of the wastewater treatment plant, so these values meet the discharge standards defined by Moroccan legislation.
