Dan DeInking Flotation Cell

Published in: Latest News

R. Dan and Co., Inc. applying patent for Dan De-Inking Flotation Cell For Paper Making Waste Paper Stock Preparation

The Dan De-Inking Flotation Cell is a newly invented equipment to apply for a grant of Philippine Patent with the Bureau of Patent (BOP) of the Intellectual Property Office (IPO) of the Philippines. Today, processing of pulp stock in the de-inking flotation for paper making is confronted with challenges: high investment cost, high production cost and reducing quality of pulp product due to deteriorating but increasing priced recycled waste papers. Dan De-Inking Flotation Cell has been developed to cope these challenges. This flotation cell for waste paper processing is capable of effectively removing printing inks and other floatable hydrophobic contaminants, i.e., stickies, wax, etc. from the stock fiber suspension. Fillers and coating particles can also be removed by this flotation. Efficiency in terms of attained stock brightness (relative to ink / other contaminants removal), is at par with other types of leading flotation cells now operating in the Paper Mills and sold in the market worldwide. This was proven in the actual test results conducted last March 2007. Attained brightness on a certain waste paper pulp stock was at 74 – 76%ISO. This is due to its diffusor that can produce a wide range of air bubbles: small and large bubbles. Very encouraging performance of this cell is its low operating cost. Actual test result showed a 43% power savings. This is because of the two-pump (high pressure and low pressure) diffuser system adopted in the cell. Added features of Dan De-Inking flotation Cell are: 1. low investment cost. Technology to make and materials needed are locally available. 2. safe and simple to operate 3. easy to expand its capacity. Continuing effort to promote the use of Dan De-Inking Flotation Cell in paper mill Waste Paper Stock Preparation in the Philippines and in the future in neighboring Asian countries is currently being developed by R. Dan and Co., Inc.. One system is under installation in one of the Tissue Paper Mills here in the Philippines.
