Abstract

In general, the main problem of domestic wastewater treatment plant (WWTP) for office buildings in Jakarta is the incompatibility between the surface load of wastewater and the capacity of WWTP. At the beginning a capacity of WWTP is already predetermined and corresponding to the rate of wastewater generated. But because of the demands of the means for the benefit of various business, so that the capacities of the office building should be developed. This case occurred on PT. Usaha Gedung BDN. Four environmental parameters, namely TSS, Ammonia, Grease & Oil and COD, produced from the WWTP still exceeded the allowable quality standards. Therefore PT. Usaha Gedung BDN immediately needs WWTP capacity development plan which is adequate. Various types of technology have been widely available and ready to be used to overcome the problems of the WWTP. But on this occasion it is advisable to develop the existing WWTP facilities by adding a new WWTP unit. The first WWTP is functioned as the preliminary processing unit and the new WWTP will become an advanced processing unit. The use of a combination of anaerobic-aerobic biofilter will be relied upon to reduce pollutants that can qualify water quality standards in accordance with applicable regulations.keywords : problem identification, domestic wwtp, advanced processing

Abstract

In order to reduce the accumulation of waste in landfill, incineration technology could becomes one of the solutions. In addition to reduce the volume of waste, the energy generated by incineration process can also be utilized. Plant Incineration consists of four categories process, namely pre-treatment process, combustion process, energy recovery process and flue gas treatment process (Air Pollution Control system). Pre-treatment process is used to increase the average calorific value of waste. Pre-treatment process depends on the type of incinerator used. Combustion process in an incinerator must accommodate the principles of 3 T (temperature, turbulence, time). Process conditions for the type of incinerator grate in accordance with the principle of 3 Tare the waste residence time in the grate less than 60 minutes, gas residence time more than 2 seconds and the gas temperature over 850 C. In the combustion process will produce heat carried by flue gas. The heat will flow into energy recovery process to be utilized. From energy recovery process, flue gas will enter into the APC system to reduce air pollution caused by combustion process.keywords : incinerator, waste, energy recovery

Abstract

In monitoring the environmental quality, besides it needs the data analysis also requires the presentation of accurate data so as to display an useful information. If the data is not immediately available it is feared worsening quality changes that will lead to difficulties in recovery. Self-monitoring analysis results database design for wastewater treatment instalation in manufacturing industry packaging cans aims to create a new procedure in terms of the storage and management to create a new procedure in termsof the storage and management of data replaces the old method is still conventional. Database design also features graphic user interface (GUI) as a medium for user interaction with the database software. Database database software is designed with the Logical database design method in which the process of making a model of the information used in the company based on the model-specific data, but does not depend on the Database Management System (DBMS). DBMS is a software that allows users to define, create, maintain, and control access to the database. Results to be achieved with the existence of this database is that users can easily perform datastorage, update the data, speed up retrieval of earlier data, and assist to present a report. Given this self-monitoring analysis results database, the data can be stored properly and safely on the database to be managed in the future as well as complementary data sources in reporting self-monitoring of wastewater treatment.keywords : self monitoring, database,DMBS, data update, and wastewater treatment plant

Abstract

In the affluent countries, the main motivations for waste reduction are frequently related to the high cost and scarcity of sites for landfills, and the environmental degradation caused by toxic materials in the deposited wastes. The same considerations apply to large metropolitan areas in developing countries that are surrounded by other populous jurisdictions. The places that currently do not have significant disposal pressures can still benefit from encouraging waste reduction. Their solid waste departments (Dinas Kebersihan), already overburdened, cannot afford to spend more money and effort on the greater quantities of wastes that will inevitably be produced as consumption levels rise and urban wastes change.Solid waste managers in developing countries tend to pay little attention to the topic of reducing non-organic wastes because the wastes they collect are between 50% to 90% organics, dirt and ashes. These municipal wastes, however, are amenable to composting or digestion, provided they contain very low levels of synthetic materials (see the Composting part of the Sound Practices section). Solid waste departments thus have an interest in promoting diversion of synthetic recyclables from the waste stream.
