          ■ COD discharge improvement method
          Continuous activated carbon COD improvement
          In case that COD exceeds discharge rules, use continuous activated carbon device after post-treatment to reduce COD from 150ppm to 100ppm.
          ■ Improve discharged water quality of high-concentration Ni wastewater
          Evaporation dehydrator Better Ni treatment water quality
          Ni treatment limit lies at 0.1ppm approximately, yet common treatment method cannot reach below 1ppm.
          Use of evaporation dehydrator and vacuum evaporation can reach discharge limit and greatly reduce chemicals consumption and sludge production.
          ■ Better oil-containing sludge dehydration in oil-containing wastewater treatment
          Multiple round-disc dehydrator Better dehydration
          Belt-type dehydrator can dehydrate sludge, yet oil will stain filter fabric, cause blockage and dehydration failure.
          Use of multiple round-disc dehydrator prevents blockage, improves dehydration efficiency, and is also suitable for organic sludge as well as high-viscosity sludge.
          ■ Less RO membrane blockage in reclaimed water recycling
          RO equipment Less RO membrane blockage
          When recycling reclaimed water, RO membrane is more likely blocked and reclaimed water devices cannot run stably.
          Use of RO chemical FR110 may inhibit RO membrane blockage and enable equipment to run stably.
