Wastewater Discharge Disposal

At Wanhua, we vigorously carry out processing of wastewater and sewage, with our wastewater reuse rate increasing every year. We have invested more than 6 million yuan to build a reclaimed water reuse system in the Ningbo Industrial Park in 2010, and the wastewater up to standards from a sewage treatment plant are subjected to ultrafiltration and reverse osmosis treatment to obtain supplemental water of circulating water, thereby annually saving 900,000 tons of fresh water. Wanhua has independently developed a technology of the integration of treatment and reuse of waste brine to turn waste materials into reusable materials, so that the worthless waste brine is changed into raw materials of 100 yuan/ton, with obvious wastewater discharge reduction effects.
