REMOVAL OF 2, 4-D FROM WATER, USING VARIOUS ADSORBENTS IN COMBINATION WITH ULTRAFILTRATION
MetadataShow full item record
The surface water bodies have become very much susceptible to pollution by pesticides due to their increased application in agriculture. Ultrafiltration is classified as a low-pressure membrane technology which effectively removes particulate matter and microorganisms and to a certain extent dissolved organic matter and color. This paper presents a pilot plant study of different adsorbents for removal of 2,4-Dichlorophenoxyacetic acid from water. The 2,4-Dichlorophenoxyacetic acid adsorption parameters by adsorbents were first determined by batch adsorption experiments. The decline in permeate flux without addition of adsorbents was greater as compared to that in hybrid process. Membrane adsorption capacity of 2,4-Dichlorophenoxyacetic acid was determined by taking samples from pipe inlet to membrane and from outlet of the membrane. From the difference in the inlet and outlet concentration in 2,4-Dichlorophenoxyacetic acid the membrane adsorption capacity was determined. The percent retention of 2,4-Dichlorophenoxyacetic acid with and without adsorbents was also determined.
