Low concentration of chlorinates maybe found in wastewater, contaminated soils and air due to different industrial sources. Low level of Volatile Organic Compounds (VOC)’s could be removed by adsorption, incineration and biofiltration methods. These methods have some disadvantages such as removal efficiency or high operation cost. Chlorine has been removed from the chlorinated aliphatic compounds under anaerobic conditions. The aim of this study was to investigate biological treatment of DCM and CT in high flow ...

This paper describes removal of Pb(II) ions from aqueous solutions using NaOH modified pine barks (Pinus nigra). Chemical modification and its enhancement effect on adsorption capacity for heavy metal treatment process have been investigated in this article. Changes of the surface properties after modification were examined by the FT-IR analysis. Maximum adsorption capacity was 49 mg/g at pH 8 and during about 180 min contact time (for 35 mg/L initial concentration with 2.5 g/L solid-to-liquid ratio) These modific...

Wastewater treatment plant design calculation is complex and time-consuming task. The person who is in charge of calculations should be sure about the criterias about the unit to be sized and should use appropriate inputs. Vital point of design is generally using the best input within the range to have more sensible results. Web based design calculations of wastewater treatment plant software has been coded. PHP and JavaScript languages have been used to achieve these advantages. With the aid of error checking, th...

Heavy metal pollution is very important problem in waste water pollution around industrial area. Cupper has been used in many industries with civilisation period and a lot of water sources were contaminated by dissolved component of cupper metal. It has incredible effect on the micro-organisms and also other living organisms in water environment. For this reason, copper content of industrial wastewater must be decreased to the limits given in the international regulations. There are many methods may be used for he...

Metropolitan city of Konya has the important agricultural activity. For this reason, it has been named “food store of Anatolia” as far as agricultural production is concerned. Many towns around Konya have to draw waters, for irrigation, from lower quality sources including municipal wastewaters. With the application to land of large volumes of minimally pretreated wastewater, it is evident that considerable potential for adverse health effects exists. Microbiological pollution could occur from food crop contam...

Recently, the noisy problem is increasing parallel to the improvement of the technology, which arises in the developed countries and makes the life difficult. It is recently one of crucial environmental problem that it is a sort of pollution, still least known and least struggled in our country. However, the investigations carried out on noise pollution have brought up that the matter is a problem of public health gaining importance increasingly. The aim of this study was noisy measurements, both to determine the ...

Recently, the effect of noise pollution appeared due to noise increasing from highway transportation, especially, the great majorities of the people living in city centers. Identifying the noise levels have gained great importance in terms of planning of the cities, regions, industries and our being informed how degree the noisy pollution have influenced our daily life. Development plans performed in our country have been carried out without taking into consideration the factor of noise pollution. One of the bigge...

A natural zeolite, Clinoptilolite was used to investigate its adsorption capacity for the lead (II) ions from artificial polluted tap water in this study. For the experimental studies, Clinoptilolite mineral which is 25-140 mesh size was used by activating with HCl, and lead ion removal efficiencies were examined. Experiments were studied under laboratory batch conditions were run at different pH values, temperatures. The highest removal efficiency was found as about 87\% at pH 5. Similarly, experiments were carri...

Many industrial processes and sewage treatment facilities produce odours, most of which are of decomposed sulphur compounds. Hydrogen sulphide (H2S), which is a very toxic and corrosive gas, may be the standard indicator among the obnoxious odours and therefore the amount released into the air is required to be regulated strictly. Hydrogen sulphide was efficiently removed from contaminated air by a pilot-scale bio-filter; a column prepared with soil, sawdust and activated sludge materials from the leather industry...

At present, there is a lot of interest in the use of dynamic simulation for optimization and operation of wastewater treatment plants. For this purpose, different mathematical models are used. Development of these models requires a complicated conceptual approach. It involves identification of all carbonaceous and nitrogenous components. The Activated Sludge Model No.1 (ASM1) presented by the IAWQ Task Group on Mathematical Modelling for Design and Operation of Biological Wastewater Treatment Processes is generall...

Different kinds of pesticide are used for protection of plant from different pests which are bacteria, insects, fungi, nematotes, worm’s etc. Generally they give some advantage farmers’ plant production, but they also have some important disadvantage with their residues on plant materials. Farmers mostly apply pesticides higher than the needed levels to quarantive the higher production. They sometime use the pesticides later than deformation period. This time some residue chemicals may still be on the applicat...

In this article, pollution of ecological systems with heavy metals and their hazardous effects were investigated as a view of waste management. Several industries from mining to electroplating produce large volumes of wastewater containing heavy metals. These wastewater cause accumulation of heavy metals through ecological circle in soil, plants and animals which directly enter human food chains presenting a high hazardous effect on consumers. They may cause severe damage of the kidney, reproductive system, liver,...

Heavy metals in wastewater are quite important because of being toxic effect for public health. Wastewaters that contain heavy metals are generally caused by industries discharged, either after primary treatment or even no-treatment farmers in Konya use wastewater for irrigation that discharged into canal. This causes soil pollution also decreases plant quality. Heavy metals can reach to humans and animals and causes toxic effects through food-chain. The aim of this study is determining heavy metal accumulation on...

Modelling of air pollution parameters, according to the meteorological data is a necessary for preventing the repetition of same problems. During recent years, neural network-based models have been shown to be powerful tools in the simulation of variations in air quality and provide better alternative to statistical models because of their computational efficiency and generalization ability. In this study, prediction of future daily SO2 concentrations in Konya (Turkey) using MLP (Multilayer Perceptron) artificial ...

Low concentration of chlorinated aliphatic compounds may be found in wastewater and contaminated soils from different industrial sources and in the air arisen from these type sources. Low levels of Volatile Organic Compounds (VOC)’s could be removed by adsorption, incineration or biofiltration methods. These methods have some disadvantages with low removal efficiency or high operation cost. Chlorine has been removed from the chlorinated aliphatic compounds by biological methods at anaerobic conditions. The aim o...
