1、 Industry challenges and user pain points

At present, the treatment of high ammonia nitrogen wastewater is facing severe challenges, and traditional processes have obvious bottlenecks:

1. Limitations of traditional methods: Blowing off method and ordinary stripping method have problems such as "pollution transfer", high energy consumption, and difficulty in achieving stable effluent standards; The membrane method is prone to fouling and blockage, and the cost of treating concentrated solution is high.

2. User core pain points:

Complex water quality: high salt content inhibits microbial activity, making direct biochemical treatment impossible.

High cost: additional carbon sources need to be added if the carbon nitrogen ratio is not suitable; Ordinary steam extraction consumes a large amount of steam and incurs high operating costs.

Difficult to meet emission standards: The effluent ammonia nitrogen concentration cannot be stably reduced to below 15mg/L.

2、 Our innovative solutions

In response to the above pain points, Dier Chemical Packing Co., Ltd. in Pingxiang City, Jiangxi Province has launched the "Combination Separation Technology", aiming to achieve the triple goals of standard emissions, resource recovery, and energy conservation and consumption reduction.

1. Core technological advantages

Deep deamination and stable compliance: Optimized distillation process and specialized high-efficiency packing are used to ensure that the effluent ammonia nitrogen content is less than 5mg/L and stably meets the first level discharge standard.

Resource recycling, turning waste into treasure: Ammonia nitrogen can be concentrated and recovered into ammonia water with a concentration of ≥ 21% (wt) at the top of the tower, which can be directly reused in production or sold as products, creating economic benefits.

Energy saving and cost reduction: The process system achieves comprehensive utilization of heat and innovatively uses secondary steam as a heat source, significantly reducing steam consumption and operating costs.

2. Research and development and strength guarantee

Dier Chemical Packing Co., Ltd. in Pingxiang City, Jiangxi Province has a large-scale tower internals testing base equipped with DN600 and DN300 thermal model test towers, which can provide you with:

Accurate experimental verification: Conduct experiments on specific wastewater for customers, obtain precise process parameters, and provide reliable basis for industrial device design.

Technical customized development: Develop customized solutions for special and difficult to treat wastewater.

3. Summary

The wastewater denitrification combined separation technology of Dier Chemical Packing Co., Ltd. in Pingxiang City, Jiangxi Province not only solves the pain points of traditional processes, but also develops towards a new direction of resource utilization, low energy consumption, and high standards.

We sincerely invite enterprises and experts facing the problem of wastewater deamination to inquire and exchange ideas, and provide you with a full process solution from experimental research to engineering application.
