The soluble sulfate ion in the acid wastewater was easily precipitated by calcium ion to form CaSO 4 and gypsum; then, the precipitated gypsum was removed by filtration. During this process, other inhibitory compounds were co-precipitated with formatted salts; however, the xylose in the solution was lost.

For highly acidic waters, forced draft degasifiers can be an effective way to raise the pH, by ,stripping, dissolved carbon dioxide from the water. Making the water alkaline helps coagulation and flocculation processes work effectively and also helps to minimize the risk of lead being dissolved from lead pipes and from lead solder in pipe fittings.
