Wastewater Reuse at a Methanol Production Plant R

The new treatment system was designed to reduce overall liquid waste from 300 to 130 tons per day, a 56% reduction. To achieve a reduction in wastewater discharge, the following changes/addi- tions were made to the system design: 1. Sludge collection systems were added to increase water recovery; 2.
