For Type I systems, the TSS of samples after addition of calcium carbonate and after addition of the product shall be at least 90 percent less th

41、an the TSS of the samples after addition of calcium carbonate, but before addition of the product. b. For Type II systems, the TSS of samples after the addition of calcium carbonate and after addition of the product corresponding to QLshall be at least 90 percent less than the TSS of the samples aft

42、er addition of calcium carbonate, but before addition of the product.
