Improvement of coagulation¨Cflocculation process using anionic

A physicochemical treatment (coagulation¨Cflocculation) was applied to a slaughterhouse wastewater, using anionic polyacrylamide as coagulant aid to improve the settling velocity of the flocs formed with the coagulants used: ferric sulphate, aluminium sulphate and polyaluminium chloride.

A review on application of flocculants in wastewater treatment

A study has reported that the combined use of coagulant (ferric chloride) and polyelectrolyte (non-ionic polyacrylamide) resulted in the production of sludge volume with reduction of 60% of the amount produced when coagulant was solely used for the treatment of beverage industrial wastewater (Amuda and Amoo, 2007).

Polymers for Coagulation and Flocculation in Water Treatment

Coagulation/flocculation (CF) is a two-stage process that involves the destabilization and agglomeration of dispersed, dissolved, colloidal and suspended particles in the dispersion medium.

Efficient and sustainable treatment of industrial wastewater

Coagulation flocculation has demonstrated that it is an effective method and TBP can be used as a substitute to classical coagulant agents in industrial wastewater treatment. TBP as a natural coagulant did not require any coagulation pH adjustment and allowed more than 60% and 96% of COD and colour removals from industrial wastewaters respectively.

water soluble polymer flocculants: synthesis

Water Soluble Polymer Flocculants: Synthesis

Polymer adsorption can occur through hydrogen bonding (polyacrylamide on silica silanol groups), electrostatic interaction (cationic polymers on negatively charged sludge), hydrophobic interaction (poly (vinyl alcohol) on silver iodide), and ion bridging (anionic polyacrylamide on negatively charged clays with the help of divalent calcium ion). 7

Revisiting Chemically Enhanced Primary Treatment of ... - MDPI

Chemically enhanced primary treatment (CEPT) is a process that uses coagulant and/or flocculant chemicals to remove suspended solids, organic carbon, and nutrients from wastewater. Although it is not a new technology, it has received much attention in recent years due to its increased treatment capacity and related benefits compared to the conventional primary treatment process. CEPT involves

Printing Ink Wastewater Treatment Using Hydrodynamic

The addition of a 4 min hydrodynamic cavitation pretreatment step reduced coagulant addition by 33%, for the treatment of undiluted PIW (with 10 mg L ?1 anionic polyacrylamide), while removals were ranged between 96 and 98%. Economic analysis for the undiluted PIW showed that costs were reduced by ca. 20% with the hydrodynamic cavitation

The Use of Polymers in the Flotation Treatment of Wastewater

When a hydrophobic analogue, such as a copolymer of acrylamide and trimethylaminoethylacrylamide chloride (PDMAEMA), which has the charge linked to a methacrylamide unit via a propylene bridge (as shown in Figure 1B) was used, the required polymer dose was more than halved (15 mg L versus 40 mg L). This was interpreted as the hydrophobicity / /
