Korea Environmental Industry & Technology Institute (KEITI) announced that it developed technology to promptly and efficiently remove nitrogen (N), phosphorus (P) and fluorine (F), which are produced by wastewater from semiconductor industry.
The technology was the outcome of a joint project by Sung Jin Engineering Co., Ltd and the department of environmental engineering of Chungbuk National University with the support by the Ministry of Environment and KEITI.
The newly developed removal facilities for high concentration N·P·F is more compact than previous facilities and processing time became shorter.
The technology crystallizes nitrogen, phosphorus and fluorine into calcium fluoride (CaF2) and Struvite before removing them. It improves water quality and Struvite, which is organic byproduct, can be used as compost.
Dr. Jeong-hun Lee from Sung Jin Engineering said the high concentration N·P·F removal technology can also be applied to other industries which discharge serious wastewater.
