Lianhua Technology has focused on developing Laboratory COD Analyzers since 1982. Our pioneer, Mr. Ji Guoliang, invented the rapid digestion spectrophotometric method, a major advancement on determining COD in sewage and industrial wastewater. His method reduced processing time while increasing method precision, setting a new standard in the industry for environmental protection. Over the last forty years, we have developed more than 20 series of water quality testing equipment, and we currently can test for BOD, ammonium, total phosphorus, total nitrogen, heavy metals and more. This speaks to the vast product innovation we’ve achieved. In excess of 20% of our global workforce operates in the Research and Development departments, and we have more than 300,000 clients worldwide. Our products find use in municipal sewage disposal, petrochemicals, and food processing industries, among others. While we look to the future and further international growth, our primary goal continues to be the protection of quality water and the provision of testing services.
