Analysis of Treated Waste Water Management of the Pulp Mill of Phoenix Pulp and Paper Co., Ltd.

Abstract

The analysis of an appropriate rate of water to be supplied to the Project Green area is presented. Project Green is a project of Phoenix Pulp and Paper Co., Ltd. To use treated waste water from the pulp mill to irrigate eucalyptus field which cover an area of about 4,000 rai around the mill. Besides, an analysis of the existing irrigation and drainage systems are also carried out in order to recommend appropriate strategies to improve the systems, and some approach to manage the treated waste water of the mill are also presented. The calculation and analysis were done by using the water-balance concept in Hydrology and based on principle of Irrigation Engineering. It was found that the mill can supply total volume of the treated waste water to the field during October to July, But there are some excess treated waters water, after supply to the field, during August and September. Some of the excess water can be diverted to Huay Chod directly, then the mill can manage the less by using recommended appropriate approach. Furthermore, some follow up and morritoring strategies for the project are presented as well in order to carry on it in the future.
