I. Project Overview
This project is located in Qingjian County, Yulin City, Shaanxi Province. The client's water source is groundwater, with a daily water consumption of 100 tons per day. Due to the geological influence of Northwest China, the local groundwater quality is complex, with excessive levels of sediment, hardness, salinity, and microorganisms, making it unsuitable for direct use in production and domestic water. A customized professional water purification system is required to ensure that the water meets standards.
II. Raw Water Quality Challenges
Through on-site investigation and water quality testing, the core problems of the raw water have been clearly identified, representing common groundwater quality issues in northern Shaanxi:
* The raw water contains a large amount of fine sediment, resulting in turbidity and high suspended solids content.
* The water hardness exceeds standards, easily causing scaling and blockage in pipes and water-using equipment.
* Sulfate and total dissolved solids are high, and mineralization exceeds standards.
* The water contains excessive microorganisms, resulting in substandard water hygiene.
* Conventional simple filtration equipment has limited processing capacity, easily leading to membrane element blockage, water quality fluctuations, and an inability to provide consistently compliant water supply in the long term.
III. Customized Water Treatment Solution
Based on the client's water quality characteristics, high sediment content, and daily water demand, we customized a combined process of inclined plate sedimentation tank and 10-ton ultrafiltration equipment. This employs a tiered treatment model of "pre-treatment sedimentation + post-treatment deep filtration" to specifically address local groundwater quality issues.
Inclined Plate Sedimentation Tank (Pre-treatment): Utilizing shallow sedimentation principles, it rapidly settles fine sediment and suspended impurities in the raw water, effectively reducing turbidity, significantly lessening the load on the downstream ultrafiltration equipment, preventing membrane clogging, extending equipment lifespan, and ensuring stable operation of the filtration system.
10-ton Ultrafiltration Equipment (Deep Water Purification):** Utilizing high-precision ultrafiltration membrane screening technology, it deeply removes fine particles, colloids, microorganisms, and other pollutants from the water, effectively optimizing key indicators such as water hardness and salinity, completely resolving water quality exceeding standards, and ensuring consistently compliant effluent quality.
IV. Core Technological Advantages
High Regional Adaptability: Specifically designed for the high-siltation, high-hardness, and high-mineralization groundwater conditions of northern Shaanxi, perfectly suited to the local water quality conditions of Yulin.
Stable Treatment Effect: The tiered purification process effectively addresses multiple issues including turbidity, scaling, and excessive water quality.
Lower Operation and Maintenance Costs: Automated operation, strong resistance to water quality fluctuations, low failure rate, and simple and convenient daily maintenance.
Precise Water Supply Matching: Equipment capacity matches the customer's daily water consumption of 100T/D, meeting routine water needs.
V. Project Operation Results
After installation and commissioning, the entire equipment operates smoothly and reliably, successfully resolving all issues related to turbidity, microorganisms, hardness, and excessive sulfate levels. The effluent is clear and clean, fully meeting the customer's production and domestic water standards. With its low energy consumption and low maintenance, it provides a long-term, reliable water purification solution, earning high praise from the customer.
