Salsnes Filter Overview Salsnes Separation ( S.A.) Pty Ltd Devlyn Fraser Product Introduction The purpose of the Salsnes Filter 1) Separation dewatering of solids, leading to the reduction of the (TSS) Total Suspended Solids in municipal effluent 2) Separation dewatering of solids in Industrial effluent, with the aim of lowering the SS, COD and BOD, effectively lowering effluent billing costs, as well as possible reductions in operations maintenance costs. Technical Overview 2 Models, SF 2000 SF 6000 Manufactured in 304 316 S/Steel Hydraulic loading of 70- 575 m3 / Hr Endless Cloth Filter, Woven Polyester, 0.1- 1.0 mm pores (785 Microns Thick) 40-70 % removal of suspended solids The cake (dewatered Sludge) 25-45 % Dry substrate Weight : 375 Kg (SF2000) 725 Kg (SF6000) Energy Consumption: 2.5 Kw (SF2000) 4.2 Kw (SF6000) Process Description Effluent inflow through inlet tube Effluent filtered through an endless Filter Cloth Removal of 40-70% of suspended solids The filtered water is released through outlet-pipe Suspended solids are conveyed by filter cloth dumped into a sludge compartment Excess sludge removed from cloth by an Air knife Primary Sludge dewatering is facilitated by gravity during transport of the sludge to the trough Process Description Secondary dewatering of sludge is facilitated by screw press compacting the sludge in the press cylinder Excess water is drained via secondary outlet Compressed, dewatered sludge (cake) is released via a spring loaded lid on the press cylinder Excess Fat deposits are removed from cloth twice per day via Hot water spray (20 Ltrs Each) - Adjustable On/Off operating speed is controlled by pressure transmitter, measuring the level of inflow, to achieve optimal balance between inflow the filters filtration properties Process is completely automated, incl. Cleaning = minimal maintenance Applications A) Overview of Expanded process at Municipal : WWTP’S Applications Cont. Salsnes Filter removes SS in paral
