This is the first in a series of three papers describing combustion of biosolids in a 5-kW bubbling fluidized bed the ash chemistry and possible application of the ash produced as a fertilizing agent. This part of the study aims to clarify whether the distribution of main ash forming elements from biosolids can be changed by modifying the fuel matrix the crystalline compounds of which can ...
Silicon-phosphorus crystals only act to prevent scale formation and corrosion. Therefore the water filtered by using silicon-phosphorus crystal . must be filtered or boiled by RO membrane before drinking. The use of silicon-phosphorus crystals in drinking water terminals must also be . equipped with a timing drain to control the concentration of silicon-phosphorus crystals in the water. Because silicon
Method for reducing phosphorus in effluents and process waters in a pulp mill or a paper mill comprises: - adjusting the pH of the water to be treated with an alkaline agent (A) - supplying carbonate ions to the water - precipitating calcium carbonate from the water to be treated by the effect of carbonate ions supplied to the water - coprecipitating phosphorus together with the ...
