Using treated wastewater from pineapple processing for irrigation

Abstract

    From the pineapple fruit processing operations emit large amounts of waste water per unit of raw material. Concentration of pollutants in this waste water is not too high, but can not discharge directly into the environment. To treat this waste water and re-use it in agriculture, biotechnology is usualy used. In areas where pineapple growth, water is often scarce, so the reuse of treated wastewater as irrigation water not only helped improve the efficiency of water use but also to raise public awareness about an environmetal friendly activity. To study the possibility of some kind of purple photosynthetic bacteria involved in specific waste water treatment processes to reduce pollutants in waste water as well as reduced operating costs and the ability to participate in the process of plant growth regulator is in progress. Capability to stimulate the crops growth of treated waste water adding purple photosynthetic bacteria has showed good results on Green Cabbage, Facol Been and Cayen Pineapple, the main fruit for tin procesing.
