The polyester plant of FEPV reuses water recycled from the cooling tower to reduce water consumption. In the case of high conductivity in cooling tower water or backwashing the sand filter, wastewater is discharged to the treatment facility, put through sedimentation and reused.  The plant determined that the recycled water can be used to recharge the scrubbing system of the flue gas desulfurization (FGD) tower to conserve water. To accomplish this, FEPV built the recycling pond and added a water pump with automatic control. Water discharged from the cooling tower would be used to recharge the scrubber in the FGD tower after going through sedimentation. The average monthly water recycled reached approximately 70kiloliters, conserving approximately 840kiloliters of water annually.
