Polyferric sulfate is a kind of inorganic high polymer flocculating agent. It possesses various advantageous characteristics, such as high speed of precipitation, high density of alumen ustum, high rate of pollution removal and low amount of sewage sludge, thereby making it an important utility for water treatment.
This compound is soluble in water and is utilized as a flocculating agent mainly used in the purification of drinking water.
Similar to other adsorbents, the efficiency of chitosan as a flocculating agent are greatly dependent on pH, agitation speed, dosage, and contact time.
F and n values of the suspensions of different structural vehicles and flocculating agent are shown in Table 2.
Several of the papers in this collection are reviews of the state of the art in a biochemical engineering technology, namely biodiesel processing, membranes for the fishery industry, sludge reduction in the activated sludge process, molecular imprinted polymers, and ?-PGA as a flocculating agent and adsorbent for cationic dyes.
This polymer is used as a thickening and flocculating agent in water purification [10].
As flocculation occurs via the flocculating agent, the interface descends until solids are settled at the bottom.
Polyacrylamide (PAM) is widely recognized as a safe, cost-effective flocculating agent for suspended sediments (William et al., 1999).
When the water containing the overspray is pumped to the 'Aqua Cleanse' tank a flocculating agent is injected, this in turn combines with the polymer and over-spray particles and forms a buoyant sludge causing it to float to the surface where it is automatically skimmed into a disposal bag.
Power Engineering Company (Salt Lake City, UT) has patented a process for precipitating and removing suspended fat and protein components and other suspended solids from a given solution accomplished by the addition of an aluminate to complex with the fat and protein components and the addition of a flocculating agent to flocculate the aluminate/fat and protein component complexes into insoluble particles capable of removal by conventional technology, which insoluble particles can be rendered to produce tallow.
* 7000 gallons per month of aluminum hydroxide solution from a plating process is being used by a sewage treatment plant as a flocculating agent.
