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

Rainwater‑sewage cross‑connections, wet‑weather overflows, and concealed illegal discharges are common pain points in industrial park water environment management. Industrial parks gather diverse manufacturing tenants with variable production schedules, which leads to random, intermittent wastewater discharge events that are extremely hard to capture by routine inspections. Traditional manual inspection cannot detect pipeline network anomalies in real

In the chemical industry, analytical samples often contain high-temperature, high-pressure, high-salinity, organic solvent, acid, and alkali corrosion characteristics. These conditions make it impossible for analytical instruments to measure samples directly, so pretreatment is required. Dongrun can provide customers with complete technical solutions, covering on-site sampling analysis, accurate instrument selection, R&D and design, integrated manufacturing, installation

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

Circulating Water Intelligent Control Solution for Clogging, Corrosion & Inaccurate Dosing Overview Faced with operational and maintenance challenges for industrial circulating water systems, the industrial circulating water quality monitoring and automatic dosing system from Shandong Dongrun Instrument delivers a professional intelligent solution built specifically for circulating cooling water systems in industrial production. It effectively resolves

The underground drainage network environment is complex, with dampness, water accumulation, debris accumulation, and poor ventilation. Ordinary monitoring equipment is highly susceptible to environmental interference and has a high failure rate, making it difficult to operate stably for a long time. The underground drainage network environment is complex, with dampness, water accumulation, debris accumulation and

On September 18, 2024, supported by the Indonesian Ministry of Public Works, the Ministry of Environment, and other departments, the 2024 Indonesia International Water Treatment Exhibition (INDOWATER) was held at the Jakarta International Expo Kemayoran. Dongrun Instruments, a leading expert in water monitoring and system intelligence control in China, participated in the exhibition with its
