(free)Why Optimise? Technical aspects • Sludge thickening vs. sludge dewatering • Operational principles ST • Reference sludge thickening + results
Why Optimise? Operator comfort Limited operator time for analysis / poly adjustments Environment – atmosphphere Operational problems / challenges Variable process feed solids Changes in polymer concentration / activity Different sludge characteristics (e.g. sludge imports from different sites / septicity)
Thickening • properties of thickened sludge • prevent thickened sludge pump clogging • polymer consumption • SRT Digester • Gas yield Gas yield and operational aspects predominant
Dewatering create cost savings in • polymer consumption • sludge disposal Polymer savings aspects predominant
