100-Mu Greenhouse Vegetable Drip Irrigation Filtration System Project in Liaoning

## Project Background Liaoning Province is an important vegetable production base in northern China with well-developed facility agriculture. A local vegetable planting cooperative owns 100 mu of greenhouses, mainly growing off-season vegetables such as tomatoes, cucumbers and peppers, and adopts drip irrigation for irrigation. The cooperative previously used simple screen filters, which had poor filtration effects, caused frequent emitter clogging, and required frequent manual cleaning that was time-consuming and labor-intensive. The cooperative hoped to upgrade its filtration system, but with a limited budget, it needed a cost-effective, practical and easy-to-operate solution. ## Solution Henan Haojun Agricultural Technology Co., Ltd. provided a cost-effective and practical two-stage filtration solution based on the cooperative's actual situation and budget: ### 1. Primary Filtration - Y-type Screen Filter - Equipped with 2 units of LZHS 2-inch Y-type screen filters - Stainless steel filter screen with large filtration area and strong dirt-holding capacity - Serves as primary filtration to remove large particulate impurities in water - Simple structure, economical price and convenient cleaning ### 2. Secondary Filtration - Manual Backwash Disc Filter - Equipped with 2 units of LZHS 3-inch manual backwash disc filters - Three-dimensional deep filtration with a filtration precision of 120 mesh - Easy manual backwash operation: cleaning can be completed simply by turning the handle - Modular design, expandable as needed ### 3. Supporting Equipment - LZHS Venturi fertilizer injector: realizes integrated water and fertilizer application - LZHS air valve: protects the pipeline system - LZHS pressure gauge: monitors system operation status ## Project Implementation The project was implemented quickly and efficiently: - Equipment production: 10 days - Logistics and transportation: 3 days (from Zhengzhou to Liaoning) - On-site installation: 5 days - Commissioning and training: 2 days Thanks to the easy operation of the equipment, the cooperative's technical personnel quickly mastered the operation and maintenance methods. ## Project Results After the system was put into operation for one planting season, the cooperative achieved obvious economic benefits: 1. **Emitter clogging problem solved**: The emitter clogging rate dropped from 25% to below 3% 2. **Improved irrigation uniformity**: Increased from 80% to 91%, leading to more uniform vegetable growth 3. **Easy operation**: The manual backwash operation is simple, and the cleaning time is shortened from 1 hour per time originally to 10 minutes 4. **Increased yield**: The per-mu yield of vegetables such as tomatoes and cucumbers increased by about 12% 5. **Fast return on investment**: The equipment investment was recovered through yield increase within one planting season ## Customer Feedback "Haojun Agriculture's filtration equipment is cost-effective, practical, reliable in quality, and very easy to operate. Our workers learned how to use it right away. When we used screen filters before, we had to take them apart for cleaning every few days, which was time-consuming and labor-intensive. Now with the disc filters, we just need to do backwashing, which is super convenient. The vegetable yield has also increased. This set of equipment is well worth the purchase!" —— Person in charge of the Liaoning vegetable planting cooperative --- *Henan Haojun Agricultural Technology Co., Ltd. provides cost-effective, easy-to-operate irrigation filtration equipment for small and medium-sized farms and cooperatives across the country, supporting the development of facility agriculture.*
