The crystals of dibasic calcium hypochlorite are preferably produced in a two-stage process. The first stage involves chlorinating a slurry of lime and separating the insoluble impurities from the mother liquor. The mother liquor is reacted in a second stage with further lime to produce the crystals of dibasic calcium hypochlorite under conditions encouraging the …

202411 · Algal fouling has become one of the most critical factors hindering the large-scale development of membrane processes in algae-laden water treatment. Herein, novel calcium hypochlorite (Ca(ClO)<sub>2</sub>)/ferrous iron (Fe(II)) process was proposed as an ultrafiltration (UF) membrane pretreatment t …

Calcium hypochlorite is an effective alternative to using bulk hypochlorite or gas chlorine for chlorination applications. It is typically less regulated, less hazardous and less corrosive than other methods of chlorination. The solution is produced in a lower concentration (~1.5%) which leads to slower degradation. The onsite generation of solution also provides for an …

202475 · Chemical Properties. Calcium hypochlorite compound acts as a strong base because it accepts H+ readily. Also, when dissolved in water, the hypochlorite anion accepts a proton from H2O by liberating OH– ion. The chemical equation for this reaction can be given by ClO- + H2O → HClO + OH-. This is also a compound, which is a powerful …
