after your process have do you have a granular activated carbon filter? We use these ALL the time to drop to TSS in the final product water but we have a treatment process upfront of course such as: traditional coagulation, flocculation, settling (usually through settling tubes), followed by a multi-media filter, followed by a GAC filter and disinfection and the water we produce meets Canadian regulations which are very strict. There are other technologies such as upflow clarifiers through a resin bead bed followed by filtration via a multi-media filter. Then of course there is electro-coagulation (which is slowly gaining popularity in Canada), dissolved air floatation (DAF) which is AWESOME for suspended solids removal (usually a coagulant is required in conjunction with a detention tank with a DAF unit), plus numerous other options. Please feel free to contact me as each water body I have ever treated is unique and they each require special tweaking to obtain the desired outcome.
