Beijing Olympic Park River System looks like a water dragon, winding the entire center area of the park. The river is 2,700 meters long, covering an area of 165,000 m2. In view of these features, the design adopted natural water view maintenance system, high filtration and enhanced phosphorus removing technology and measures to purify, maintain and comprehensively treat the water, fulling the high standard requirements of the river system regarding recycling water utilization and its quality.

OriginWater Technology made its solutions to address the challenge concerning the water quality, proposing to apply its Natural Aquatic System (NAS) independently developed by the company. The NAS is an enhanced water quality ecological purification technology that adopts natural water ecological system purification principle.  

The NAS inoculates microorganism into water for purification to build water plant system with purification function, aquatic animal system, bottom sludge animal system and microorganism system, applying the biological decomposing function of plant - animal - microorganism composite ecological system to effectively and economically fulfil the objective of water purification; and taking on a beautiful natural water view with the landscape design.
