    Clarifier operations costs are low since little maintenance and low power are required. Useless sludge obtained from clarification can be disposed of by one of three methods: (1) drying in shallow basins; (2) using a vacuum filter; (3) or a centrifuge. The first method costs from $1 to $3 per ton of dry solid

    Atmospheric CO2 is stored as calcium carbonate in the brick itself, guaranteeing permanent sequestration. These bricks are shaped hexagonally for added strength, and in a hypothetical next step, the team would add polyvinyl alcohol to solve mud-bricks’ historic susceptibility to breaking due to weight-induced pressure and weather-induced

    The reaction combines calcium from the phosphate rock with sulfate, forming calcium sulfate (CaSO 4), commonly referred to as gypsum. Gypsum is separated from the reaction solution by filtration. A dihydrate process produces gypsum in the form of calcium sulfate with two molecules of water (CaSO 4 2H 2 O or calcium sulfate dihydrate). During

    By careful addition of the sodium alginate solution to a calcium chloride solution, calcium alginate can be precipitated in the form of fibres. This fibrous calcium alginate can be readily separated on a metal screen, washed with water and when treated with dilute mineral acid, the Ca ++ ions are exchanged for H + ions, and it yields fibrous
