Altering textile manufacture to minimize treatment needed for wastewater reclamation

Maria Eduarda de Carvalho Beja Neves, Purdue University


The research involved the uses of water and chemicals in the textile industry. A linear programming model was developed, capable of minimizing the cost of treatment needed for wastewater reclamation. This was accomplished through the selection of the optimum set of chemicals in respect to their removal from a wastewater by biodegradation, and by so doing, preventing the accumulation of inorganic dissolved solids in the reused wastewater, even with prolonged reuse. Different values were tested for the wastewater reclamation rate, and for the percentage of biodegradable materials used by the industry. The industrial processes themselves were considered as blocks, with different manufacturing objectives and using different kinds and quantities of chemicals. The cost of wastewater treatment was influenced by the nature of the chemicals and by the wastewater reclamation rate.
