135m³/hr Reverse Osmosis Irrigation Water Treatment
1.Background：
1.Located in Canada—renowned for premium grape cultivation and wine production 82.36-acre grape plantation. Grapes demand stable, high-quality irrigation, requiring watering every 7–10 days during key growth phases .However, local raw water fails to meet grape irrigation standards: with 5.17dS/m electrical conductivity, 39.86mg/L sodium, and high TDS. Long-term use of this high-salinity water .To solve this, dongguan hiayuan water treatment reliable solution delivering consistent low-salt irrigation water (EC < 1dS/m) to meet the 82.36-acre plantation’s large demand. This led to the collaboration on the 135TPH reverse osmosis (RO) irrigation water treatment project.
2. Raw Water & Product Water Requirements:
2.1 Raw Water Quality Parameters:
pH Value :7.27
Electrical Conductivity:5.17ds/m
Sodium Content:39.86mg/L
Raw Water Requirement:lear and transparent, no obvious pollutionsuspended solids, turbidity and otherindicators need to be stable)
2.2 Product Water Standards:
Core Water Quality Index:Electrical Conductivity< ldS/m(Meetsagricultural irigation water requiremnents:135m3/hr (81.1ppm)
Water Production Capacity：Application Scenario:Farmland irrigation water supply
3.Reverse Osmosis (RO) Process Solution:
Three Φ2200×3600 carbon steel filters connected in series, along with three sets of electric butterfly valves, enable precise on/off control, flow regulation, and system protection of the water flow in the pipeline, suitable for high-flow irrigation of 135 m3/h. After media treatment, chemical scale inhibition extends the lifespan of core equipment, ensures stable water production, and improves TDS water quality. Using 84 ULP22-8040 and 36 FR12-8040 membranes of different models, it meets the requirement of EC < 1 dS/m for grape irrigation while reducing costs and avoiding frequent membrane cleaning that could disrupt the irrigation cycle.
Our design process flow is as follows:
3.1 Process Flow
Adopting “Pretreatment + Reverse Osmosis” core process, the specific flow is as follows:
Raw Water Pump (with frequency conversion control) → MultimediaFilter → Antiscalant Dosing Device → Precision Filter → High-Pressure Pump → ROSystem (with CIP Cleaning) → pH Adjustment Device
4.Project Advantages:
1. Efficient Desalination: RO system has stable desalination rate, ensuring product water conductivity < 1dS/m, which meets irrigation water standards
2. Stable Operation: Equipped with frequency conversion control and pressure difference monitoring devices to adapt to raw water quality fluctuations
3. Energy-Saving Design: Key equipment adopts high-efficiency motors, 184KW total power matches 135m3/h water production capacity, optimizing energy consumption ratio
4. Easy Maintenance: Equipped with CIP chemical cleaning system, facilitating daily maintenance of RO membranes and extending equipment service life.
