After determining the necessary dosage and location of the application, the aluminum sulfate is added to the surface of the lake near the wake of the outboard motor. This provides sufficient mixing of the aluminum sulfate within the epilimnion. [9] The necessary dosage of alum is determined by a variety of parameters.
A common example is phosphoric acid, which additionally converts some iron oxide into an inert layer of ferric phosphate. [3] Most of the rust converters contain special additives. [4] They support the rust transformation and improve the wetting of the surface. Applied rust converter
Enhanced biological phosphorus removal (EBPR) is a sewage treatment configuration applied to activated sludge systems for the removal of phosphate. [ 1 ] The common element in EBPR implementations is the presence of an anaerobic tank ( nitrate and oxygen are absent) prior to the aeration tank.
Phosphonates are also used as concrete retarder. [7] [8] They delay the cement setting time, allowing a longer time to place the concrete or to spread the cement hydration heat on a longer period of time to avoid too high temperature and resulting cracks. They also have favourable dispersing properties and so are investigated as a possible new ...
Trisodium phosphate (TSP) is an inorganic compound with the chemical formula Na 3 P O 4. It is a white, granular or crystalline solid, highly soluble in water, producing an alkaline solution. TSP is used as a cleaning agent, builder, lubricant, food additive, stain remover, and degreaser. [7]
It uses a specially fluidized and siliconized monoammonium phosphate powder. [1] ABC dry chemical is usually a mix of monoammonium phosphate and ammonium sulfate, the former being the active component. The mix between the two agents is usually 40–60%, 60–40%, or 90–10% depending on local standards worldwide.
