Determination of amoniac, nitrite, and nitrate content in seepage waste water in landfill area in cold water, Padang have been done using spectrophotometric method. Sample took from sequencing ofseepage waste water treatment process. The results showed that the ammonia, nitrite, and nitrate content in seepage waste water were 137.612 to 400.298 mg/ L, 0.34 to 0.756 mg/ L, and 0.682 to5.842 mg/ L, respectively. The differences of ammonia, nitrite, and nitrate content in seepage waste water and ammonia and nitrite contents tend to decrease while the nitrate content tends to increase. The rate of ammonia degradation in water seepage was different for each sampling place where the rate of degradation was greatest in seepage water waste treatment II. This degradation is expected to reduce the level of pollution on the environment.

Treatment Facilities

It is obvious that hospital waste water is one of the most potential pollutant to the evironment. Thus the waste must be treated properly before it is disposed of to the public sewage facilities. However, limited fund usually become an obstacle when hospitals will construct waste treatment facilities, especially for midle and small typed hospitals.Considering the problem, development of proper waste treatment facilities which is cheap in terms of technology and price and easy operated is very important.This paper describes scheme of biological waste water treatment unit for hospitals which is suitable for Anaerob-aerob Biofilter waste water treatment process. By applying this system Anaerob-aerob Biofilter, concentration of COD, BOD and suspended solid material can be reduced significantly as well as detergen and ammonia. Keywords : rancang bangun, waste water, biofilter, Anaerob-aerob

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.

Informal Urban Settlements

The Vaal River Barrage reservoir is an important source of raw water for Rand Water which supplies at least 10 million people with drinking water daily. Return effluents from waste water treatment works, industries and informal urban settlements in the catchment has resulted in algal problems in the raw water and treatment process. In order to attempt to reduce the effect of eutrophication of South African inland water quality the Department of Water Affairs implemented in 1985 a 1 mg/l ortho-phosphate standard for waste water treatment works effluents. The amount of phosphate originating from the waste treatment works decreased significantly over the 10 years after the standard was implemented even though 40% of the time the works do not comply to the standard. This has resulted in no significant change in the chlorophyll values at Rand Water Intake No. 1. The algal species composition has changed with blue-greens becoming more dominant which has resulted in a higher incidence of algal related problems. The stabilizing of the chlorophyll values is not only as a result of lower ortho-phosphate levels but also due to residence times, turbidity and conductivity. To further reduce the algal concentrations at Rand Water Intake No. 1 the 1 mg/l ortho-phosphate standard will have to be enforced, the standard possibly reduced and diffuse sources managed on a catchment basis.

Microorganism Immobilization

The PAN-based carbon fiber (CF) was choosen as a bio-carrier in waste water treatment process, which was modified by anodic oxidation and electropolymerization using sulphuric acid and maleic anhydride (MA) respectively. The morphology and propeties of CF surface were characterized by laser confocal microsopy (LCM), X-ray photoelectron spectroscopy (XPS) and the degree of moisture (DM), and the consequence of biocompatibility nature on CF surface was therefore indicated by immobilization results of microorganisms. It shows that the surface hydrophilicity, oxygen containing groups and surface roughness of CF would contribute greatly to improve the immobilization ability of microorganisms on CF surface. And acid anodic oxidation is more effective on microorganism immobilization than MA electropolymerization.
