RELAÇÃO ENTRE O ENTUPIMENTO DE GOTEJADORES E OS ATRIBUTOS FÍSICO-QUÍMICOS E MICROBIOLÓGICOS DE EFLUENTE DE LATICÍNIOS DILUÍDO

Resumo

The reuse of water stands out due to the current scenario of water scarcity and environmental degradation, however the physical-chemical and microbiological characteristics of the wastewater cause the emitters clogging of the localized irrigation systems. In this context, the objective of this work was to analyze the changes in the uniform distribution coefficient and statistical uniform coefficient of drip units equipped with five types of emitters, which applied diluted dairy effluent in public supply water in a ratio of 1: 3 (one part of diluted dairy effluent in three parts of public supply water). The experimental tests were carried out in the Laboratory of Pollution and Soil Degradation of the Universidade Federal Rural do Semi- AÌrido, where, by means of the mounting of an experimental platform containing five drip units, its performance was evaluated every 40 h until the time total of 200 h. The pH, electrical conductivity, suspended solids, dissolved solids, calcium, magnesium, total iron, total manganese and total coliforms were determined in this experiment. The results indicated that the Netafim Tiran dripper was the most susceptible to the clogging caused by the physico- chemical and microbiological agents of the diluted dairy effluent.
