The company has 6 major categories, 36 series, 92 varieties of water treatment equipment specifications. Long-term commitment to reverse osmosis (RO), electrodialysis (EDR), ion exchange (H-OH), intelligent softening (ZNR), microfiltration (MF), nanofiltration (NF), ultrafiltration (UF), electrodeionization (EDI) and other water treatment, water reuse, sewage treatment and other technology development and innovation, product promotion and engineering undertaking; the company has strong technical force, a total of 26 national patents, Tsinghua University, Nankai University, Shanghai Jiaotong University research base; Eco-Environmental Research Center of Chinese Academy of Sciences environmental industry demonstration base.

Shandong Water Environment Technology Co., Ltd. and the most competitive domestic and foreign research institutes and enterprises to develop with independent intellectual property rights of high-performance aromatic polyamide hollow fiber composite nanofiltration membrane materials and components products, the Shenhua Ningxia Coal Industry Group Shenhua Shendong Coal Group Co., Ltd., Yanzhou Mining Group, Huaneng Group, CNPC, Sinopec Group and other units, proved that the device has good performance, stable operation and easy operation. At the scientific and technological achievements appraisal meeting organized by Science and Technology Department of Shandong Province, experts agreed that the decolorization rate of wastewater from secondary sedimentation tank of printing and dyeing wastewater treatment plant was 92.9% and the COD removal rate was over 80% The separation of dye, salt and water is effectively realized. The nanofiltration membrane is applied to the decolorization and the removal of organic matter. Several demonstration projects have been successfully implemented, which have good prospects for popularization and application. The project achievements have generally reached the international advanced level of similar products.
