A coal chemical company in Xianyang, Shaanxi Province, suffered a major loss in 2024 due to its desire for a cheap solution. It purchased three standard water softening units from another region, but within just six months, the equipment broke down. The resin became caked with silt, iron, and manganese, boiler scale reached 2 millimeters thick, thermal efficiency plummeted by 22%, and monthly gas costs increased by an extra 120.000 yuan. The RO membrane even failed three years prematurely. By 2025. after switching to a localized solution from Xi'an DIEN, it saved nearly one million yuan in a year, recovering all its previous losses.
Chemical companies operate around the clock, and general-purpose equipment simply cannot withstand such high-intensity loads. In less than six months, the hardness of the effluent exceeded the standard range, forcing production to be reduced. Maintenance workers worked overtime daily for emergency repairs, the workshop director was frantic with worry, and the purchasing manager was ashamed and unable to lift his head after being reprimanded by his superiors.
Water Softening Equipment
Firstly, the hardness of the boiler feedwater exceeded the standard. This caused the scale on the boiler tubes to thicken, and energy consumption to rise sharply. Subsequently, heat exchange efficiency decreased, significantly increasing the risk of localized overheating. Safety inspectors lived in constant fear of accidents.
The situation was even worse in the fine chemical reaction process. Calcium and magnesium ions mixed into the raw materials, completely disrupting the reaction ratios and causing a sharp decline in product yield. The downstream RO membrane and EDI module suffered severe scaling and blockage due to substandard feed water. Replacing a set would cost hundreds of thousands of yuan, leaving the finance department green with envy upon seeing the bill.
DIEN's Solution: Survey Before Design
Before developing a solution, DIEN sends engineers to the plant to collect water samples for testing, assess the plant's production load, and measure the relevant space dimensions of the machine room. This isn't a matter of simply copying a template; rather, because each factory has different water quality and operating conditions, a customized design is required for each factory.
The factory in Xianyang has exceptionally high iron and manganese content in its groundwater. Therefore, a multi-stage filtration module was installed before the softening unit to intercept impurities. The resin was no longer contaminated, extending its lifespan by 40% and significantly reducing the frequency of consumable replacements. Traditional single-tank water softeners inevitably require a water outage during regeneration, forcing the production line to stop. However, DIEN uses a dual-tank design (one tank for operation, one for backup – click to learn more: one-tank-for-operation-one-backup water softening equipment), automatically switching between regeneration and flushing operations. The water supply remains uninterrupted throughout the entire process, ensuring the chemical industry's production rhythm is completely unaffected. Industries like coal chemical and new materials are particularly vulnerable to production stoppages, as even a one-hour shutdown can result in losses of hundreds of thousands of yuan. The dual-tank alternating design completely solves this headache-inducing problem. As a result, workshop supervisors no longer need to anxiously watch the clock while waiting for regeneration to complete, and production scheduling becomes much easier.
Modular Design Adaptable to Older Plants
Many older chemical industrial parks around Xi'an have cramped and small machine rooms, making large-scale civil engineering impossible. DIEN has designed its equipment with a compact, modular structure, requiring no infrastructure modifications and allowing direct integration into existing water supply pipelines. It can be installed in both new and old plants.
Water Softening Equipment
Xi'an DIEN, a custom water softening equipment manufacturer, adapts its products to various industries. The intelligent control system has been optimized for regeneration time and salt consumption ratios, ensuring stable and compliant water hardness. At the same time, industrial salt and water/electricity consumption is reduced by 30% compared to general-purpose equipment, resulting in considerable savings over time. Their engineering team is based in Xi'an, and their spare parts warehouse maintains a constant stock of readily available components. They can respond quickly to requests from Jinghe Industrial Park, Yulin Coal Chemical Base, and Baoji Chemical Industrial Park, providing localized service throughout the entire process, from free testing and on-site installation to 24-hour after-sales support and regular inspections. This avoids the frustrating wait times often associated with out-of-town brands.
Regarding the field of chemical water treatment, it's not simply about looking at impressive specifications, but rather about ensuring the equipment is perfectly suited to local water quality, production schedules, and existing plant conditions. The money saved on general-purpose equipment will ultimately be squandered on energy consumption, maintenance, and consumable replacements.
