• Abstract:

  Obtaining good quality water

  through treatment and reuse processes for

  human consumption, irrigation and industrial

  use should be a constant concern and of

  great strategic interest. For reuse of water, considering its purpose, the treatment is

  necessary to remove excess salts, hydrocarbons and other organic pollutants, toxic

  or corrosive metals and formation of scale in pipes and equipments. Water reuse

  strategies have been developed in an attempt to reduce costs and avoid environmental

  impacts in effluent disposal. Water treatment and reuse require alternatives to currently

  available processes, preferably at low cost and using inputs largely generated as waste

  from productive activities, such as fishing and agribusiness. In the perspective of the

  elaboration of filter elements, with variable compositions, this article deals with the

  production of clay-polymer composites based on powder of the green coconut shell and

  modified clays of the group of phyllosilicates (bentonite and vermiculite), for the removal

  of pollutants from aqueous media. The development of the work involved treatments

  and transformations in the powder of the green coconut shell, including its hydrolysis,

  for the later association of chemically activated clays, with monitoring by SEM, FTIR,

  FRX and XRD analyzes to obtain composites with potential for application in filter

  pellets. Adsorption tests revealed efficiency of the vermiculite-cellulose phosphorous

  composite obtained in the hard water softening.
