Effect of Temperature and Water Quality on Migration of Total Organic Carbon from the High-Density Polyethylene Drip Irrigation Pipes
Abstract:Three brands of high-density polyethylene (HDPE) drip irrigation pipes were tested about total organic carbon (TOC) migration to distilled water, dispensed water and nutrient solution. And four successive tests each of 72 h duration were carried under the different conditions. Test about effect of hold water quality in the pipes on TOC migration was made under 25±5 °C and in the dark. And the relation between water quality and TOC migration was significant (P = 0.04). To discuss about effects of environment temperature, (20 °C, 30 °C and 40 °C) three temperature gradients were set based on physical environment in greenhouse. At the same time, interactions between water quality, temperature and brands was also analyzed. Results showed that TOC migrating from different brands of pipes tended to improve with increased temperature during all of test periods. Considering comprehensive effect of temperature, water quality and brands, temperature was the most significant (P = 0.011), brand was the second (P = 0.019), water quality has the minimum effect (P = 0.016), and interactions among three factors were existed significantly (P = 0.043).
