Similar to Benchmark but with pre-oxidation by KMnO4 and Dual Media Filtration (GAC/Sand)
Cascading aerator and KMnO4 will provided a more complete removal of iron and manganese
Dual Media Filters GAC/sand – will be able to give better removal of organics with GAC filters, less likelihood of formation of disinfection by-product; able to give better filtered water quality
