| This study aimed to evaluate the uniformity of drip irrigation systems with application of water and cassava effluent from a facultative pond. Were determining the coefficients of variation of emitter discharge (CVq) and Christiansen uniformity (CUC). The experiment was conducted at cassava processing factory in the city of Terra Roxa/PR, were installed two systems of 66 m², fed by one tank of 1000 L situated at 1.5 m above the ground and containing water (treatment 1 - T1) and effluent from facultative pond (treatment 2 - T2). These systems were stored and tested again after one year with water (treatment 3 - T3) and effluent from facultative pond (treatment 4 - T4), and performed thirty trials for each treatment, using the methodology of Keller &... |

| This study aims to evaluate the linear relationships between total solids (ST), fixed solids (SF), volatile solids (SV) and their electrical conductivity (CE) of influent and effluent in a biodigester used in the cassava effluent treatment. Were collected 20 samples from the input and output of a digester installed on an agribusiness in western of Paraná State. Samples were collected every two days and analyzed as parameters: electrical conductivity, total solids, volatile and fixed. The best linear relationship was obtained between CE and SF for the two collection points, which presented equation with r2 equal to 0.921 for the input and 0.694 to the output. By Pearson correlation test, there was a very strong interdependence between the CE and SF... |
