Biological filter-removing rates of suspended particles in aquaculture wastewater by experimental bivalves.

Sedimentation rates (mg•d−1): the sedimentation rate of suspended solids in the FT system; Ratios of sedimentation rates: ratios of the sedimentation rate of suspended solids in a bivalve treatment to that in the control (without bivalves); Percentage of TSS reduced (%): percentage of TSS reduced in the outflow water in oyster or mussel treatment, compared with control treatment without bivalves. Values are given as means±SD. Values with different superscripted letters in the same column are significantly different from each other (PBiological filter-removing rates of suspended particles in aquaculture wastewater by experimental bivalves.
