Application of Air Flotation Machine in Printing And Dyeing Wastewater Treatment

Air flotation machine, also called dissolved air flotation machine, is a sewage treatment device that uses small bubbles or tiny bubbles to cause impurities in the medium to float out of wastewater. Sewage contains some fine substances with a specific gravity close to that of water, and its self-weight is difficult to sink or float, and air flotation machine can be used. Air flotation machine developed by Runneng has the characteristics of low operating cost, strong applicability, wide application range and high processing efficiency. It can be widely used in the purification of sewage in paper industry, chemical industry, printing and dyeing industry, food processing, beer manufacturing, pharmaceutical industry, slaughtering and other industries.

A Jiangsu textile printing and dyeing company is located in Yixing city, Jiangsu province. It was established in 2003 and covers an area of 73,000 square meters. It is a professional manufacturer engaged in flannel printing, dyeing and bleaching. Annual production capacity is 38 million meters and the output value exceeds 100 million yuan. This company has domestic advanced production equipment and technology. It has 4 rotary screen printing lines, 2 dyeing lines, 31 pile machines, 2 pre-treatment production lines and 2 steaming machines. Printing and dyeing wastewater mainly consists of desizing wastewater, scouring wastewater, bleaching wastewater, mercerized wastewater, dyeing wastewater, printing wastewater, etc. These kinds of wastewater contain unreacted dyes, auxiliaries, products after reaction and detachments on fabrics, as well as carcinogenic and teratogenic organic compounds, toxic heavy metals, etc., with strong color and high component hazard. The existing sewage treatment equipment of this company cannot guarantee the effluent compliance. Therefore, Jiangsu customers invited Runneng to develop a suitable printing and dyeing wastewater treatment plan to solve the problem of unsatisfactory wastewater discharge.

Runneng sewage treatment engineers consulted Jiangsu customers on the main production process, learned the specific source of wastewater, treated water volume, treatment process, and went to the site for on-site investigation, sampling for water quality testing. And we finally determined to add a Runneng brand RN-OAQF-500 air flotation machine on the basis of the original wastewater treatment equipments.

Air flotation machine parameters

Air flotation machine model is RN-OAQF-500
Processing capacity is 500m3/h
Air flotation machine size is 20.9×4.3×1.8m
Number of aerators is 1 set
Total power is 10.3 KW

In May 2016, Runneng package and load the RN-OAQF-500 air flotation machine customized for Jiangsu customers and transport it to the scene in Jiangsu. After both parties’ inspection, the packaging, model and technical parameters of the air flotation machine are all in line with signed technical agreement. Our technicians instructed installer to install and debug for customer, and then enter trial run phase. At this stage, air flotation machine is in good condition. After inspection by staff, all of water quality indicators are in line with the “Textile Dyeing and Finishing Industry Water Pollutant Emission Standard” GB4287-2012. At this point, Jiangsu customer printing and dyeing wastewater treatment project was completed.
