Title

Investigation on the Effect of Filters Used in the Fish Farms on Water Quality (Case study: Fish farms at Shahrekord)

Pages

  57-67

Abstract

 Background and Objective: Fish farming projects are one of the human activities that can negatively affect the Water Quality of rivers. Therefore, reducing water pollution in Fish Farms is very important. In this study, in order to reduce the pollution of the effluent, various Filters of natural materials were investigated. One of the problems that these Filters may cause is the reduction of Water Quality by the materials used in them. The purpose of this study was to investigate the change in Water Quality of Fish Farms when passing through various materials to make Filters. Method: For this purpose, a series of PVC columns with a height of 70 cm were used to study the changes in acidity, electrical conductivity of water and all soluble solids. In this way, the pipes were divided into two halves from the middle and a layer of geotextile was placed between each pipe. Then various materials such as Zeolite, sugar beet pulp, wheat bran and fodder corn were poured into the tubes to a height of 10 cm and water was continuously passed through the columns for 15 minutes. Then, the inputs and outputs of the columns were sampled for 2, 5, 10 and 15 minutes. Findings: According to the obtained results, the values of electrical conductivity of water and total solids of water outlet solution initially increased and decreased over time, so that the mentioned values initially increased 275. 27 and 278. 4%, respectively, but eventually they came back to the initial value. Discussion and Conclusion: Comparison of the quality of the outflow water with the permissible values of the output to the river showed that in all the mentioned times, the mentioned values are within the permissible range and the materials used as a filter do not pose a problem on the quality of the outflow water.
