As a Shaanxi-based industrial water purification equipment manufacturer with services covering the entire Shaanxi province, DIEN has its own 3.000-square-meter standardized production workshop. Completely abandoning the industry's common practice of rigidly applying standardized equipment to every situation, our technicians conduct on-site water sampling and testing at three different times of day (morning, noon, and evening). We tailor solutions to each company's specific needs, considering all raw water indicators, effluent standards, machine room dimensions, and peak production water usage. Our core products include dual-stage reverse osmosis pure water equipment, industrial ultrafiltration water purification equipment, underground integrated sewage treatment equipment, and circulating water side-stream filtration equipment. All equipment is equipped with a variable frequency linkage fully automatic control system, enabling unattended operation. The core membrane elements are selected for their high fouling resistance, adapted to the local high-hardness water characteristics, achieving a concentrate recovery rate of up to 80%. Our processes fully comply with Shaanxi's local sewage discharge standards for the Yellow River Basin, helping companies achieve compliant production while significantly reducing long-term water costs.
Reverse Osmosis Equipment
A large machinery processing enterprise in Xianyang requires a large amount of pure water for equipment cooling and precision workpiece cleaning in its production process. The existing single-stage equipment, used for four years, required shutdown for chemical cleaning of the membrane elements every two months due to the high hardness of the local water. Fluctuations in effluent quality resulted in watermarks on the workpiece surface, reducing the product qualification rate to only 92%. Monthly downtime for maintenance exceeded three days, and the effluent exceeded suspended solids standards, prompting the local environmental protection department to order rectification. After two consecutive days of on-site surveys, the DIEN Technology team customized a 20T/H dual-stage reverse osmosis industrial water purification system + pre-treatment enhancement + simplified wastewater treatment solution: The softening tank diameter was increased by 20% to address the high hardness of the Guanzhong Plain water. A multi-media filter and activated carbon unit were added to pre-filter sediment and impurities. The variable frequency system dynamically adjusts its operating power according to the production load, achieving a concentrate recovery rate of 78%. A simple sedimentation filtration module was added to the effluent to ensure stable and compliant discharge. Since its commissioning, the equipment has experienced zero unplanned downtime in 10 months, the membrane element cleaning cycle has been extended to 8 months, the product qualification rate has increased to 97.5%, and monthly savings in water, electricity, and maintenance costs are nearly 5.000 yuan. The wastewater discharge passed environmental inspection on the first attempt. The client's representative commented: "We compared five or six industrial water purification equipment manufacturers in Shaanxi, and only DIEN provided a solution after conducting three on-site water tests at different times. They didn't just offer a low price based on a generic configuration list. The equipment operates stably, with low noise and low energy consumption. Their after-sales engineers can arrive within 2 hours in the city. We will definitely choose Dean again for our future expansion of the new workshop."
As a Shaanxi industrial water purification equipment manufacturer deeply rooted in the local market, DIEN has a complete local warehouse with spare parts. They offer 24-hour on-site response throughout Shaanxi, providing free on-site water quality testing and customized solutions. From pure water production to compliant wastewater discharge, they ensure the entire process is implemented, safeguarding the water safety and environmental compliance of local industrial enterprises.
