Research on water reuse possibilities in railways reservoirs washing process

Abstract

In this work wool and two types of hemp (crude and processed) were used in column test to figure out the best recycled sorbent to reduce color in railways reservoirs washing water (later RRWW). For every sample pH, conductivity, turbidity, iron and color were measured at laboratory. According to the results of column test it was discovered that 1,8 L of RRWW can be treated by using only one column. And the best sorbents to reduce color in RRWW is processed hemp and wood. With the help of these sorbents color was reduces in 3,7-3,8 times.
