The expression of excessive iron and manganese water quality is as follows: the well water is relatively clear when pumped up, and after standing or airing for a period of time, the water quality turns yellow and has a rust smell.
The development of the theory and technology of iron and manganese removal in groundwater has experienced three stages: natural oxidation, aeration contact oxidation and biological manganese removal. The first two methods have complicated technological process, difficult management and high operating cost. The cost of culture of biological method is high, the culture and domestication of bacteria need a long time, the operation is complicated, and it is difficult to popularize in the project. According to this situation, the company has developed a set of convenient groundwater iron manganese removal program, the specific content is as follows.
1, the role of the sedimentation tank is mainly to make the iron and manganese ions in the water and oxygen ions in the air chemical reaction time, the generation of iron trioxide/manganese dioxide and other precipitates. Make the water yellow, which is more conducive to the later filtration effect.
2, booster pump function is mainly to pressurize raw water, to provide power source for the system.
3,iron and manganese removal filter is mainly used to intercept trivalent iron or manganese compounds, through the further reaction of the deep filter material, so that the residual bivalent iron and manganese is adsorbed and intercepted, so as to achieve the effect of removal.
4, the main function of activated carbon filter is used to absorb the water in the raw water color, odor, residual chlorine, chlorine byproducts and organic matter, part of the pigment and chlorinated hydrocarbon substances, reduce the chemical oxygen consumption COD.
5, precision filter aperture is only 1-5 microns, can filter the fine sediment in the water, the suspended impurities in the water has a very obvious filtering effect
Through the above five steps, we can well solve the problem of excessive iron and manganese in groundwater. If you are not clear, please feel free to contact our technical staff for consultation.
