In the Copperbelt Province of Zambia, the testing center of a large Chinese-funded mining company once faced severe challenges: The old pure water equipment it used produced water with unstable quality, high fluctuations in resistivity, and occasional exceedances of bacterial indicators. This seriously affected the accuracy of high-precision instruments such as ICP-MS in detecting trace elements in the ore, making the reports questionable in terms of credibility and even potentially causing errors in resource assessment.
Core pain points of the customers:
The water quality fails to meet the standards, which prevents the issuance of internationally recognized testing reports.
2. The equipment has a high failure rate, is difficult to maintain, and there is a lack of professional support locally.
3. The operating energy consumption and the cost of consumables replacement are not transparent.
Baihupu Customized Solution:
After conducting a detailed analysis of the customer's raw water (a mixture of local municipal water and groundwater) and conducting a survey of the water usage points, the Bihupu technical team designed and delivered an intelligent ultra-pure water integrated system consisting of "enhanced pre-treatment + double-stage reverse osmosis (RO) + EDI + terminal polishing".
Phase 1: Intelligent Preprocessing
For raw water with high hardness and high turbidity, a combination of multi-media filtration, carbon filtration and softening is adopted, along with an automatic backwashing function. This significantly reduces the load on the subsequent main system and is suitable for the variable water source conditions in Zambia.
Phase Two: Core Desalination and Purification
The two-stage RO design ensures a desalination rate of up to 99%. The water produced by the primary RO is used as the feed water for EDI, ensuring that EDI operates at its optimal condition and produces stable, low-TOC III-grade pure water.
Phase Three: Ultra-purification and Supply
The EDI module continuously produces II-level pure water with resistivity ≥ 15 MΩ·cm, which then enters the circulating pipeline equipped with ultraviolet sterilization. At the critical water intake point of the instrument, a Bihupu intelligent terminal ultra-pure water machine is installed for final polishing of the mixed bed, immediately producing I-level ultra-pure water with a resistivity of 18.25 MΩ·cm and a TOC of < 5 ppb, which directly meets the strict requirements of ICP-MS.
Intelligent Control and Remote Support
The system is equipped with Baohupu's intelligent Internet of Things (IoT) control system. Customers can monitor water quality, flow rate, pressure and consumable lifespan locally in real time. The Baohupu China technical support center can also remotely diagnose the system status, issue early warnings for faults, and guide local on-site engineers for maintenance, thus perfectly solving the problem of overseas service response.
Implementation Results:
Water quality leap: The produced water maintains a stable and continuous flow, exceeding the ASTM Type I standard. The instrument's baseline is stable, and the reproducibility of the detection data has significantly improved.
Operational cost reduction: The system has a high recycling rate, low energy consumption, and an extended replacement cycle for consumables. Through intelligent reminders, precise replacements can be achieved, resulting in a reduction of approximately 30% in annual operating costs.
Service Assurance: Relying on remote support and local training, we have achieved "7x24 hours" technical support, resulting in extremely high customer satisfaction.
This case demonstrates that in the complex application environment of Zambia, it is crucial to choose a partner that combines cutting-edge technology, adaptive design, and strong remote support capabilities. Bihupu not only provides equipment, but also offers "water solutions" that allow customers to rest assured.
