PROJECTS

Wotai Pharmaceutical Drug Preparation Efficiency Improvement Project

Wotai Pharmaceutical Drug Preparation Efficiency Improvement Project

A pharmaceutical manufacturer encountered insufficient adsorption capacity with their existing packing material during drug preparation, resulting in reduced process efficiency and inconsistent active ingredient recovery across production batches.


Shandong Binzhou Qihua Chemical Wastewater Treatment Micro-Electrolysis Project

Shandong Binzhou Qihua Chemical Wastewater Treatment Micro-Electrolysis Project

A chemical manufacturer in Binzhou, Shandong faced persistent wastewater treatment compliance failures. Rongjian developed a tailored micro-electrolysis iron-carbon packing solution, supplying over 100,000 tonnes of 14–18mm iron-carbon media forming a multi-pore structural matrix that permanently eliminates passivation and plate formation.


Zhichuang Wastewater Treatment Plant AO Bioreactor Performance Improvement Project

Zhichuang Wastewater Treatment Plant AO Bioreactor Performance Improvement Project

A wastewater treatment facility experienced frequent clogging in their AO (anoxic-aerobic) bioreactor with existing packing media, compromising biological treatment performance and effluent water quality.


Nanxiang Chemical Plant Cooling Tower Efficiency Improvement Project

Nanxiang Chemical Plant Cooling Tower Efficiency Improvement Project

A chemical production facility found that long-term use had degraded the packing in their cooling towers, reducing heat exchange efficiency and increasing energy consumption.


Shanxi Datong Mining Tailings Water Treatment System Optimization Project

Shanxi Datong Mining Tailings Water Treatment System Optimization Project

A mining operation in Datong, Shanxi required effective treatment of tailings water containing high concentrations of suspended solids and heavy metal ions to meet water safety standards.


Hengrui Chemical Cooling Tower Efficiency Upgrade Project

Hengrui Chemical Cooling Tower Efficiency Upgrade Project

A chemical plant found that severely aged packing in their cooling towers had caused a significant drop in heat dissipation performance, failing to meet growing production demands while increasing energy consumption and maintenance costs.
