Extracting the maximum benefit from condensate polishing systems continues to be a top priority among many electric utility plants. With cost reduction pressures and increasing water quality standards, owners and operators continue to evaluate the resin handling procedures that affect corrosion product transport and contaminant ion impurity levels.
Performance studies show that crushed recycled glass can provide capital and annual cost savings over traditional sand filter media.
This article defines what organoclays are and details how they are being used to remove oil and grease from wastewater.
