Recently, China Classification Society issued the “China Classification Society Type Approval Certificate†for the 718 SCW series of marine domestic sewage treatment devices. This is the first time that the 718 civil property project has been approved by the National Classification Society, marking the level and capacity of the plant for mass production of domestic sewage treatment plants. The SCW series of marine domestic sewage treatment devices produced by 718 were submitted to China Classification Society in September 2005 for approval. China Classification Society reviewed the documents submitted by 718 and formed an audit team to produce equipment. On-site inspections were carried out on testing equipment, production processes, quality control systems and the technical level of the personnel involved. At the same time, the product approval type test was carried out by the surveyor on site. The results of the review, inspection and test are in compliance with the requirements of the China Classification Society. China Classification Society believes that the 718 has the capacity and conditions for mass production of domestic sewage treatment plants, and agrees to pass type approval.
