Novel thermodynamic mechanisms of co-conditioning with polymeric

This study investigated the combined effects of polymeric aluminum chloride (PAC) and polyacrylamide (PAM) on sludge dewatering, aiming to unveil underlying mechanisms. Co-conditioning with 15 mg g ?1 PAC and 1 mg g ?1 PAM achieved optimal dewatering, reducing specific filtration resistance (SFR) of co-conditioned sludge to 4.38 ¡Á 10 12 m ?1 kg ?1 , a mere 48.1% of raw sludge's SFR.

polyaluminium chloride dosing effects on coagulation performance: case

Polyaluminium chloride dosing effects on coagulation performance: case

The average PAC dose, since its introduction in December 2016, was 33.2 mg/l, with minimum and maximum dosages of 14.1 and 43.8 mg/l. Since PAC's introduction, the turbidity of the flocculated water has remained fairly stable, within the range 3.5 to 6.1 NTU. When alum was in use, the range was 2.0 to 6.4 NTU .

The new life of traditional water treatment flocculant polyaluminum

Polyaluminum chloride (PAC) is an inorganic polymer material that has the advantages of a simple preparation process and special electronic structure. It is considered to be the most efficient and widely used occulation material for water treatment. In this work, PAC has been used as a Lewis acid catalyst fl

Effectiveness of synthesized aluminum and iron based inorganic polymer

Three inorganic polymer coagulants, namely, polyaluminum chloride (PAC), polyferric chloride (PFC) and polyaluminum ferric chloride (PAFC) were synthesized and tested for the treatment of simulated pulping wastewater. PAC exhibited the best performance for organics removal from the wastewater among all coagulants. PACs with basicity 2.0¨C2.7 ...

Organic and Inorganic Matter Removal Using High Polymeric Al

The ability of locally laboratory-synthesized polyaluminium chloride (PAC) with high Al13 content (PAC-Al13) to remove organic, inorganic matter and colour from potable water, agricultural and electroplating wastewaters was evaluated relative to commercial PAC (PACI). PAC-Al13 used in this study was prepared using batch titration of NaOH into AlCl3¡¤6H2O solution under vigorous stirring as ...

The SS content decreased to 15.1 and 7.5 mg/L at 60 min for wastewater treated by PACl/APAM and PACl/DMDAAC-AM polymer. SS content increase can be found during the settling process for raw and PACl coagulated wastewater. However, no obvious SS increase occurred for wastewater treated with DMDAAC-AM polymer.
