Automatic surface water quality monitoring stations serve as core infrastructure for watershed environmental management, cross-section assessment, pollution tracing and early warning. They are widely deployed in rivers, lakes, reservoirs, drinking water sources and transboundary monitoring sections. Shandong Dongrun Instrument delivers a full-process integrated turnkey construction solution. Complying strictly with surface water monitoring standards, our solution

The drainage conditions in chemical parks are highly complex, with a high risk of mixing between stormwater and process wastewater. Once leakage or illegal discharge occurs, it can create serious environmental risks. A reliable water quality monitoring system for chemical park stormwater and sewage networks is therefore an essential tool for environmental supervision and early

Small leaks in chemical plant circulating water systems may seem trivial, but they represent a significant hidden energy cost. A single 3 mm leak can discharge hundreds of tons of water per year. More seriously, leaks often allow process materials to enter the circulating water, causing COD and turbidity to spike. Once water quality is

To ensure production safety, many chemical plants habitually control the circulating water supply temperature at an “absolutely safe” low level—for example, keeping it below 28℃ all year round. However, this “over-cooling” comes at a high energy cost: for every 1℃ drop in supply temperature, the power consumption of cooling tower fans and circulating pumps increases

Boiler feedwater quality is a critical factor in power plant operation, as it directly determines heat transfer efficiency and equipment service life. Poor water quality can easily lead to pipeline scaling, corrosion, and deteriorated steam quality, resulting in increased unit energy consumption and unplanned outages. Therefore, boiler feedwater monitoring is a core part of water-steam

As an important part of smart water network construction, the online water quality monitoring system for drainage pipelines is developed and manufactured by Shandong Dongrun Instrument based on the actual operating conditions of domestic pipeline networks. It adapts to various drainage monitoring scenarios and realizes real-time water quality data and digital management. The system can

Industrial wastewater has long been the weakest link in the water pollution prevention and control chain, and is regarded as one of the most challenging problems in the water treatment sector. There are two main reasons. First, its complex composition and variable properties make pollution control extremely difficult. Second, treatment technologies are often site-specific and

Faced with operational and maintenance challenges for industrial circulating water systems, Shandong Dongrun Instrument specializes in water quality monitoring and automatic control. We have developed a professional intelligent monitoring & automatic dosing solution built specifically for circulating cooling water systems in industrial production. It effectively resolves common industry pain points: low accuracy of conventional manual
