The acrylamide copolymer flocculant may comprise either an anionic acrylamide copolymer flocculant or a cationic acrylamide copolymer flocculant or both.
Sealable flocculant ports are provided for inserting a flocculant into the mixing section of the housing.
The flocculant injection device injects a flocculant into the solute-containing water supplied to the pretreatment device.
The activated metal salt flocculant is produced by electrolyzing a metal salt flocculant or an aqueous solution containing the metal salt flocculant.
The stabiliser may be included during the production of the focculant or to an existing flocculant.
The composite flocculating agent consists of a chemical precipitating agent and an organic high-polymer flocculating agent.
Provided is a polymer flocculating agent.
An inorganic flocculating agent may be added into the processed water.
The invention relates to a process for treating hydrous sludges containing heavy metal salts and primary flocculating agents; the flocculating agents used are acrylamidoxime-acrylhydroxamic acid copolymers.
The processing method comprises the following steps: configuring a composite flocculating agent, charging the composite flocculating agent, regulating a pH of a solution, and performing mixing, flocculating and filtering.
The flocculent is preferably a cationic, non-ionic or anionic flocculent.
The flocculent tank is designed to be in fluid communication with the container, such that the flocculent flows from the flocculent tank to the container.
Water from feed point (7) passes through a flocculent retention chamber (8) and flocculent is added at high dosage.
A system comprising the sludge management apparatus and a flocculent tank for containing flocculent.
Optionally, an anionic or cationic flocculate may also be added.
To the biologically-treated palm oil effluent from the aeration tank (2), a flocculant supply means (10) supplies a flocculant.
The method comprises adding the polymeric flocculant to a sludge optionally after addition of an inorganic flocculant or organic cationic compound, and then dehydrating the sludge.
The polymer may be used as a flocculant.
The leach slurry is subsequently treated with a flocculant.
The resulting flocculant has a very high flocculation speed.
Lastly, the resulting mixture is dosed with a high molecular weight flocculant.
The originated suspension can be further activated by an organic flocculant.
Suction airlift pumping devices (118, 122) communicating with the collector (108) serve to elevate the flocculent to a trough (120), whereupon the flocculent is returned to basin (12).
Anionic polyacrylamide as flocculant and coagulant
Optionally, a flocculant is also used to further improve the observed synergism.
