Large-Scale Irrigation Filtration System Project for a Palm Oil Plantation in Indonesia

## Project Background Indonesia is the world's largest palm oil producer, and palm cultivation is a key economic pillar of the country. The large palm oil plantation covered in this project is located on Sumatra Island, Indonesia, with a total planting area of 2000 hectares, and its main irrigation water source is drawn from a nearby river. During the rainy season, the river carries extremely high sediment loads, which caused frequent clogging of the plantation's original simple filtration system. This led to low irrigation efficiency and severely impacted the growth and yield of palm trees, creating an urgent need for the client to source an efficient, reliable filtration system to address the issue. ## Solutions Based on the client's source water quality and irrigation requirements, Henan Haojun Agricultural Technology Co., Ltd. provided a complete multi-stage filtration system solution: ### 1. Primary Filtration - Centrifugal Filters - Equipped with 3 units of LZHS 4-inch plastic centrifugal filters - Uses centrifugal force to separate large-particle sediment from river water - Achieves sand removal efficiency of over 95%, significantly reducing the load on subsequent filtration equipment ### 2. Secondary Filtration - Fully Automatic Backwashing Disc Filtration System - Equipped with 2 sets of LZHS H-type 4-inch 6-module fully automatic backwashing disc filtration systems - Flow rate of a single system reaches 240 m³/h - Adopts dual control of pressure differential and timing, realizing automatic backwashing without manual operation - Delivers filtration precision of 120 mesh, ensuring effluent quality meets drip irrigation requirements ### 3. Control System - Hydraulic Control Valves and Irrigation Controllers - Equipped with LZHS hydraulic control valves including solenoid on/off valves, pressure reducing valves, pressure sustaining valves and other components - Paired with intelligent irrigation controllers to realize zoned, scheduled automatic irrigation - Supports remote monitoring and mobile APP control ## Project Implementation The project took only 45 days from contract signing to full delivery: - Day 1-15: Equipment manufacturing and quality inspection - Day 16-25: Ocean freight to Port of Jakarta, Indonesia - Day 26-35: Customs clearance and inland transportation to the project site - Day 36-45: On-site installation, commissioning and client training Henan Haojun Agricultural Technology Co., Ltd. dispatched professional technical personnel to the site to guide installation, ensure proper system setup and commissioning, and deliver systematic operation training for the client's operation and maintenance staff. ## Project Outcomes Since the system was put into operation, it has delivered remarkable results: 1. **Improved irrigation efficiency**: The system operates stably, increasing irrigation uniformity from the original 75% to 92% 2. **Reduced maintenance costs**: The fully automatic backwashing function eliminates the need for frequent manual cleaning, cutting required operation and maintenance staff by 60% 3. **Increased yield**: Palm tree growth has improved significantly, with an expected annual yield increase of 15-20% 4. **High client satisfaction**: The client spoke highly of the system stability and professional services provided by Haojun Agricultural, and signed a letter of intent for cooperation on the subsequent Phase II project ## Client Testimonial "The filtration system from Henan Haojun Agricultural Technology Co., Ltd. has completely solved our long-standing problems of high sediment content in river water and frequent filter clogging. The system runs stably with a high level of automation, which has greatly reduced our operation and maintenance costs. We are also very satisfied with the professional technical support and timely response from the Haojun team." —— Engineering Manager, the Indonesian Palm Oil Plantation --- *Henan Haojun Agricultural Technology Co., Ltd. has focused on the R&D and manufacturing of agricultural irrigation filtration equipment for 14 years.
