GZXZEP will exhibit at the 15th Leman China Swine Conference & 2026 World Swine Industry Expo, held from 22 to 24 October 2026 at the Zhongyuan International Convention and Exhibition Center (Zhengzhou Airport Economy Zone, Henan Province). Visitors will find our team at Booth W3111, where we will present our odor control and water treatment programs for pig farms and livestock operations.
Widely regarded as the largest annual gathering of the global swine industry, the Leman China Swine Conference enters its 15th edition this year. The 2026 program is built around the theme “Science-driven pig farming, green development,” with a conference agenda covering genetics and breeding, disease prevention and control, smart farming, nutrition — and, increasingly central to farm operations, environmental protection and emission reduction. The concurrent World Swine Industry Expo occupies a planned exhibition area of 120,000 square meters, with more than 1,000 exhibiting companies and an expected 150,000 trade visits from around 20 countries.
Pig farm odor control. Our plant-based deodorizer is dosed into the circulation water of the odor-control wall (scrubbing wall) already installed on the barn exhaust. As the water film trickles down over the packed media, it brings the exhaust air into contact with the treatment solution and adsorbs and neutralizes odor molecules before the air is discharged.
Odor assessment and formulation screening. Odor control is verified, not assumed. Our laboratory evaluates gas samples and water samples, screens deodorizing formulations, measures NH₃ and H₂S with a gas analyzer, and assesses how long a formulation stays effective under defined conditions — including parallel screening of several formulations on the same source sample.
Wastewater and slurry treatment programs. Beyond exhaust air, we supply treatment chemicals for swine wastewater, including emulsion breaking, coagulation, decolorization, foam control and biological treatment support, as well as microbial products and external carbon sources for denitrification.
Custom formulation. Where a standard product cannot meet the required result, our team evaluates the customer’s water sample, operating conditions and treatment targets to develop or adjust a formulation.
