Abstract

In the event of natural disasters such as earthquakes, tsunamis, landslides, floods and droughts, water occupies a key role in disaster relief. The presence of water is important for drinking, cooking and support the refugee areas of environmental sanitation and avoiding disaster victims of diseases waterborn disease. Water problem in disaster conditions may occur partly as a result: the disturbance of water sources because change of water quality, to become turbid or salty, the destruction of a piping system, treatment plant damage, disruption of distribution systems, or the scarcity of water in evacuation areas. Introduction of water quality becomes important to determine which process technology will be used and saved investments in emergency conditions. Priority handling of clean water usually comes first in the refugee areas with communal system, because the need of water for bathing, washing and toilet is big enough, while for a drink in the early events during disaster dominated by bottled water, but for their long-term, they have to boil water. For remote areas and difficult to reach individuals who usually use  system more simple and easily operated. Water Supply Technology for emergency response has the characteristic 1). Able to operate with all sorts of water conditions (flexible & adaptable), 2). Can be operated easily, 3). Does not require much maintenance, 4). Little use of chemicals, and 5). Portable and easy removable (Mobile System). Keywords :  Water Quality, Water Treatment Technology, Drinking Water, Emergency Response, filtration, ceramic filtration, Ultra filtration, Reverse Osmosis, Ultraviolet Sterilizer, Ozonizer, Disinfection.

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,

Abstract

Principle of zero delta Q policy is that a development should not  increase water discharge to drainage system. Policy of zero delta Q is apply to zone of recharge area and other zone which is not recharge area as well, because this area which is not as recharge area has contribute a great deal to local flood. Based on this therefore implemention of policy of zero delta Q is applied to urban area such as Jakarta. Activities proposed for Jakarta were: 1. Optimize use of water reservoir, pond and site; 2. Implementation of artificial recharge or could be combined with biopore; 3. Effective land use by provide open green areas; and 4. Normalization of drainage system. Keywords : policy, zero delta q, flood, artificial recharge, biopore, development

Abstract

A brackish water treatment process technology based on reverse osmosis principle has been applied in an Islamic school community “Raudlatuttalibin”, Rembang, since July 2008. Production capacity of the water treatment plant was designed 10M3 of drinking water per day. After running the system for one and a half years, a lot of problems were consecutively appearing untill the end of March 2010. This identification activity clarified all problems in detail and explained how to solve them. They are not only technical problems, but also social and cultural problems of the community. To solve them it must be started from increasing the capability of operators and applying the clean production concept. Finally by changing all the technically broken spareparts and running the RO unit system properly, they will be guaranteed to be able to produce good quality of drinking water.  Keywords : water treatment plant, reverse osmosis, technical & social problems.

Abstract

Domestic wastewater from the regional office in Jakarta is one of the contributors to environmental pollution. Many office buildings in Jakarta are not managing the domestic wastewater, except BPP Technology  office has managed its domestic wastewater  by  building domestic wastewater treatment plant. Increasing officers caused  decrease performance and unsufficient capacities of WWTP. WWTP expansion is needed to address the problem of environmental pollution. The success of the development of WWTP is determined by input data (soil research data) with high accuracy, design, and construction. Number of failures of civil construction in recent years due to the use of land in excess of eksploitatif carrying capacity in general, for example, groundwater exctraction  in excess can cause degradation of land, construction of road above the critical height cause sliding and high buildings construction affect to the surrounding land. The research of the soil is required for the planning of WWTP BPP Teknologi. The study was to estimate the soil carrying capacity of the soil layers that had been done by conducting experiments such as the SPT (Standard Penetration Test), Sounding and Boring. Implementation of activities include soil testing in the field and soil testing in the laboratory,  physical test and mechanical test, test to determine the value of ground forces. Sondir was conducted in three locations until the impermeable soil and drilling was implemented in depth of 4,00 m.. Four tubes of soil samples  consisting disturbed soil and undisturbed soil from depth of 1,5 m – 2,00 m and 3,00 m – 3,50 m were taken from drilling to be analyzed in the laboratory. Keywords: IPAL, soil sounding and boring, Cone penetration test, pemampatan tanah

Abstract

The  increased  use  of  pesticides  has  led  to many  benefits  such  as  advanced  productivity and lower maintenance costs  in agriculture. On the other hand, their  adverse  effects  have  also  grown : an increase of  the risks to the ecosystem and human health. Pressure driven technique such as reverse osmosis and nanofiltration have the potentiality to remove hazardous organic micropollutants such as pesticides. The rejection characteristic of artificial water with 10 ppb concentration of endosulfan and organochlorine pesticides from upper Citarum water shed sample were investigated with a commercial low pressure reverse osmosis unit on laboratory scale. Rejection and flux were measured with a varied operational parameters ; pH, pressure, and feed concentration. Endosulfan rejection was achieved > 80% with all varied operational parameters. There was a little dependence permeate flux and percent of rejection on pH. An increasing pressure caused a higher permeate flux while there was no effect of an increasing pressure to higher percentage of endosulfan rejection. An increasing feed concentration caused a lower permeate flux due to an increasing osmotic pressure.  An increasing feed concentration also result in an increasing percent of endosulfan rejection. Organochlorine pesticides found in river water sample which are lindane, aldrin, and heptachlor were all rejected 100%. This may be caused by natural organic matter present in river water and hydrophobicity. Percent rejection was constant to pressure and pH variation. Keywords : Low Pressure Reverse Osmosis, Organochlorine Pesticides, Pressure, pH, Feed Concentration

Abstract

Regional Drinking Water Company (PDAM) of County Ogan Komering Ilir has two problematic water treatment units. The first is located in Danau Teloko and the other is in the Teluk Gelam. The main problem is that many organic pollutants (namely peat water) contained in raw water. Therefore, PDAM can not be optimal to supply all the needs of drinking water for the community. PDAM have tried to treat the raw water of peat with the process of flocculation and coagulation, but the results did not meet quality standards as drinking water. This research is a trial test to obtain the optimum condition for flocculation and coagulation processes in water treatment. The results were very succesful and get the optimum pH is about 7.5 and a chemical dose of 80 ppm Aluminum Sulphate as the coagulant. Turbidity of water produced is 4 NTU and visually looks very clean. Better to add a synthetic polymer (PAC) as an additive to the process of flocculation and coagulation. Based on calculations, PDAM Danau Teloko will require the amount of coagulant (Aluminum Sulphate) 138.24 kg per day to produce 40 liters of drinking water per second. Keywords : Raw Water, Flocculation, Coagulation,  Water Treatment Plant

Abstract

The increasing variety of industrial activities in Indonesia resulted in ground water reserves in some areas experiencing drought. Exploitation of ground water by industry and the community in some big cities like Jakarta, resulting in the decrease of ground water and ground water quality reduced caused sea water instrusion. While the potential of wastewater produced by industrial and household waste high today. Based on the matters mentioned above and see the use of ground water that will be even greater in the future, then one of alternative that a lot of attention in many countries around the world are using wastewater reuse, particularly urban domestic wastewater (municipal wastewater) as a source of raw water for water supply. BPPT as a government office has made use of wastewater reuse technology, however, when the performance of the appliance is not working properly for it is necessary for re-evaluation and selection of wastewater reuse technology for better and sustainable. Keywords : Wastewater Reuse Technology, Domestic Wastewater, Water Consumption Survey

Abstract

Hospital is playing an important role in serving people who need to get health. On the other hand its occurrence causes some problems as well. One of them is the infectious wastewaters which are potential to cause a dangerous effect for human life. A lot of hospitals in Indonesia do not have the proper wastewater treatment plant yet. The local hospital of County Timika has already had a wastewater treatment plant (WWTP), but until now the capacity of the unit can not fulfil the required level of environmental standard yet. One of the problems is the technically improper treatment processes. To solve the problems, the WWTP must be redesigned and modifief by using a combination technique of anaerobik and aerobic biofilter treatment processes.The newly proposed design process of WWTP for the local hospital in TImika has already prepared to be applied. Keywords : Medical Wastewater Treatment Process, anerobic/aerobic biofilter

Abstract

Industry is a potential source of water pollution, it produces pollutants that are extremely harmful to people and the environment. Many industrial facilities use freshwater to carry away waste from the plant and into rivers, lakes and oceans. Inorganic industrial wastes are more difficult to control and potentially more hazardous Industries discharge a variety of toxic compounds and heavy metals. The most pollutans heavy metals are Lead, Cadmium, Copper, Chromium, Selenium, Mercury, Nickel, Zinc, Arsen and Chromium. Heavy metals are dangerous because they tend to bioaccumulate. Mercury for example, causes damages to the brain and the central nervous system, causes psychological changes and makes development changes in young children. Normally Mercury is a toxic substance which has no known function in human biochemistry.There are several methods to eliminate or remove heavy metals in water such as chemical oxidation process, ion exchange process, adsorption process, an electrochemical process, reverse osmosis process and other alternative methods likes biosorption. Each method has strengths and weaknesses, therefore to choose the method of removing heavy metals in wastewater depending on pollutants conditions such as concentrations of heavy metals in wastewater, types of heavy metal, heavy metal concentrations in treated water, land availability, flow rate of wastewater will be processed and other parameters. In this paper discusses several methods of removal of heavy metals in industrial wastewater such as chemical precipitation and oxidation processes, adsorption and ion exchange process. Keywords : water pollution, heavy metal, industrial wastewater, removal methods
