Flocculant Screening for the Pretreatment of Printing and

Abstract: Study on the pretreatment of printing and dyeing wastewater with PAC銆丗e 2 (SO 4) 3 and FeCl 3 was carried out. Effects of the flocculants dosage, pH on the treatment efficiency were studied. The results showed that with PAC, Fe 2 (SO 4) 3 and the FeCl 3 dosage rising, the treatment effect first decreased and then increased and when

CN105366786A - Silk printing and dyeing wastewater treatment

The invention relates to a silk printing and dyeing wastewater treatment process based on cellulose flocculant. Silk printing and dyeing wastewater is put into a storage tank and subjected to destabilization pretreatment through polyaluminum sulfate, the modified cellulose flocculant and a coagulant aid are added, the mixture is stirred, left to stand and precipitated, and a supernatant and

assured by raising the added flocculant amount. However, the increase of added flocculant very often has a negative effect on the rheological behavior of the sediment, as stronger and wider networks of flocculant and particles are formed. Fig.1 sets out the main steps of the screening method, as derived from the stated requirements.

Flocculent - Swimming Pool Water Treatment Chemical from

Flocculant creates larger clumps that sink to the bottom of the pool, and cannot be removed by your filter and this is the only point of difference. Swimming Pool Flocculants are common but there are other types of flocculants in forms of polymers usually used in Gray Water Treatment Plants, STP, and ETP.

Flocculation behaviors of a novel papermaking sludge-based

In our previous studies, several papermaking sludge-based flocculants (PSBFs) were synthesized from wood pulp papermaking sludge. The structure-activity relationships of the PSBFs have been investigated in simulated dye wastewater treatment, but their efficiencies in practical printing and dyeing wastewater (PPDW) treatment are unknown. Herein, an PSBF was prepared, and its performance is
