Perencanaan Instalasi Pengolahan Limbah Cair Rumah Sakit Aliyah 3 Kota Kendari

The purpose of this study was to determine the amount of liquid waste discharge at the hospital. Data from the number of hospital patient beds is 54 beds, so the activities taking place in Aliyah Hospital 3 in Kendari city produces a maximum discharge of liquid waste of 3.78/day. The form and design of processing liquid waste which is a rectangle with anaerobic- aerobic bio filter treatment system. Liquid waste processing with anaerobic-aerobic bio filter process consists of several parts namely the oil separator tank, equalization tank, early settling tank, anaerobic bio filter tank, aerobic bio filter tank, final settling tank and equipped with a chlorinated contractor tub. As for the size of each tank, which is like an oil separator tank (0,9 m × 0,5 m × 0,7 m), equalization tank (2,6 m × 1,3 m × 1,1 m), early settling tank (1,6 m × 0,8 m × 0,9 m), anaerobic bio filter tank (2,5 m × 1,3 m × 1,4 m), aerobic bio filter tank (1,8 m × 1 m × 1 m), final settling tank (1,8 m × 0,7 m × 0,7 m) and chlorinated tank (0,6 m × 0,3 m × 0,4 m). This process system was chosen because it is in accordance with the amount of liquid waste treatment system is safe, inexpensive and easy to operate.

Paper Mill Wastewater

The paper mill located in Indiana began operation in 1975. The initial effluent treatment system was aeration stablization and settling basins. The waste system discharged to the Wabash River. Primary solids from the clarifier are recycled to the mill. Secondary solids from the settling basins were applied to farm land. Original B.O.D. load entering the first aeration basin was 4,000 Kg per day @ 3786 cubic meters water per day. Present raw waste discharge is about 11,000 Kg per day @ 3786 cubic meters. The production rate has increased from 318 to 545 metric tons per day. The designed waste treatment system was 240 horsepower of surface aeration. In an attempt to keep up with the increasing B.O.D. load, surface aeration horsepower was increased to 450. This combination resulted in greater production of secondary solids (biomass). An anaerobic pilot plant study was conducted in 1978. Based on the study's results, the Indiana Water Pollution Control Division approved conversion of the Newport effluent treatment system to an anaerobic/aerobic system. In November 1978 we converted one aeration basin to an anaerobic cell. (The first paper mill in North America to have such a system). The other aeration basin received a total of 300 horsepower available aeration. From November 1978 to April 1979 we learned the operational controls and modified the anaerobic cell. In May 1979 the anaerobic pond efficiency was 80% B.O.D. reduction. Total effluent system efficiency has averaged 98% for the past 3 years. Aerobic biomass generation has been reduced 80 to 90% as measured by settleable solids. Recent studies and project modifications will reduce the aerobic biomass even further. In changing to anaerobic-aerobic treatment a seventy percent production increase has been possible without expansion of the wastewater treatment facilities.

Basically, nature has the ability to perform the restoration of environmental damage caused by increased human activity, but because of the limited carrying capacity, then the environment has decreased the quality from year to year. In saving the environment, technology plays a role in reducing the risk of pollution, increased efi siensi process, and creating processes and environmentall friendly products, monitoring and prediction of environment quality, environmental pollution control, restoration and environmental improvement. Waste Technology (end of pipe technology) are widely used to cope with environmental pollution, both for liquid waste, solid and air. Waste processing technology developed for the waste can be in accordance with quality standards thathave been established, while monitoring technology has been developed either manually or automatically. For recovery and improvement of technology has been developed remedies and restoration that rely on bacteria in nature.Keywords: end of pipe technology, reuse, recycle, reduce (3R), carrying capacity, and environment pollution

Trout Farms

The aim of waste modelling in aquaculture is to provide tools for simulating input, transformation, output and subsidiary degradation in recipients of organic compounds, nitrogen, and phosphorus. The direct purpose of this modelling is to make it possible for caretakers and water authorities to calculate waste discharge from existing and planned aquaculture activities. A special purpose is simulating outcome of waste water treatment and altered feeding programmes. Different submodels must be applied for P, N, and organics, as well as for the different phases of food and waste treatment. Altogether this calls for an array of co-operating submodels for a sufficient coverage of the options. In all the required fields there is some scientific background for numerical model approaches, and some submodels have been proposed. Because of its multidisciplinary character a synthesized approach is still lacking. Within trout farming this work attempts to establish the different submodels and outlines future possibilities for synthesizing the knowledge to a numerical model.
