Introduction: Matching a 50g/hr ozone generator to an 8-10 m³/h irrigation flow depends on actual water flow, ozone demand from the water source, feed gas capacity, cooling water availability, and the treatment goal.
Matching a 50g/hr ozone generator to an 8-10 m³/h irrigation flow comes down to three real numbers: the water flow you actually run, the ozone demand created by your water source, and the feed gas supply you can provide. Most farm decisions start with a pump curve, a reservoir, and a specific problem: biofilm building up in drip lines, algae in a storage pond, or a microbial load you want reduced before water reaches the root zone. The right unit is rarely the largest one on the price list. It is the one whose output, concentration, and mixing setup match the flow you run and the schedule you irrigate. Confirming those numbers before you contact a factory keeps the quote accurate and the installation straightforward.
Three inputs decide the rest of the selection: flow rate, water source, and treatment goal. Flow rate should be the number your pump delivers during a normal irrigation cycle, not the pipe diameter shown on a drawing. For a farm running 8,000 to 10,000 L/hr through one treatment point, that range is the design target. You also need the peak flow. Many systems draw more when several zones open at once, and a unit sized for the average can fall short on those days. Record both the average and the peak before comparing models. Water source changes the demand side of the equation. Clean well water with low organic load needs less oxidation than a surface reservoir collecting runoff, crop residue, and dust. FAO water quality guidance makes the same point at the management level: source, salinity, and biological load drive how irrigation water should be handled, so two farms with identical flow numbers can still need different treatment strength. The treatment goal narrows the choice further. Controlling biological clogging in micro-irrigation emitters is a different job from sanitizing a large storage reservoir, and both differ from polishing recycled return water in a closed loop. Because dosage varies with water source, contact time, mixing efficiency, water temperature, and the target goal, testing your source water is what turns a general specification into a working setting. A basic lab panel on your source water, plus a clear statement of what you want the water to do, gives an equipment supplier enough to work with.
The GW-50 (No. GW-50G) carries four numbers that define the match: 50g/hr ozone output, 80-100 mg/L output concentration, a matching water flow of 8,000-10,000 L/hr, and a feed gas flow of 10 L/min. Output sets how much oxidizing capacity you have per hour. Concentration tells you the gas stream is strong enough to dissolve efficiently rather than mostly escape. The flow range tells you how much water that capacity is designed to travel with. When a farm’s irrigation flow sits inside the 8-10 m³/h window, the generator operates in its intended band instead of being stretched or throttled back.
The series runs 20g/hr, 30g/hr, 50g/hr, 80g/hr, and 100g/hr, so the real question is where your site sits inside that ladder. If you push the full 8-10 m³/h through one treatment point continuously, 50g/hr is the natural starting size. If you treat a smaller side stream, or dose intermittently into a reservoir across the day, a 20g/hr or 30g/hr unit can cover the daily volume at a lower cost. If your peak flow climbs above 10 m³/h, if the water carries a heavy organic load from a recycled source, or if you want to dose at more than one injection point, 80g/hr or 100g/hr gives you the headroom to keep treatment strength steady. Sizing on peak demand rather than the monthly average is what keeps performance stable through the season.
Ozone output depends heavily on what you feed the machine. The GW-50 calls for 10 L/min of feed gas to hold 80-100 mg/L concentration, and clean, dry, oxygen-rich gas is what keeps the discharge tube producing at its rating through a long shift. Damp or oily air pulls output down regardless of the nameplate rating. The second half of the job is dissolving the gas into water. A venturi injector, static mixer, or contact tank gives the ozone a chance to transfer into the water, and enough downstream pipe run gives it time to react before the water reaches an emitter. Heat is the third factor: this unit is water-cooled and needs 0.3-0.8 m³/hr of cooling water to hold output during continuous operation, so plan that requirement into the pump station layout from the start.
A precise inquiry gets a precise answer, and the information a factory needs is mostly information you already have. Start with flow: average and peak, in L/hr or m³/h, plus whether treatment happens inline continuously or intermittently into a tank. Then provide the water source and, if available, a recent lab result covering turbidity, organic load, iron, and manganese. Add your treatment goal in plain terms—emitter and line biofilm control, reservoir algae reduction, or general irrigation water sanitizing—along with your irrigation schedule and how long water sits between treatment and use. Cooling water availability matters too, so note the flow and temperature you can supply for the 0.3-0.8 m³/hr cooling circuit. Describe your feed gas plan as well: PSA oxygen, bottled oxygen, or dried air delivered at 10 L/min. A few commercial points are worth settling in the same message. Confirm the electrical supply for your region, since voltage, phase, and frequency determine how the unit is configured before it ships. Ask whether the quote covers the ozone generator alone or also the injector, mixer, and any monitoring instruments, so you are comparing like for like. Ask about MOQ, lead time, packing for overseas freight, and warranty terms—the GW-50 series carries a 1-year warranty. It also helps to mention the output range you may need later, because asking about the 20g/hr through 100g/hr variations in one conversation lets you plan multi-zone expansion without starting a second round of quotes. Green Ozone works as an agricultural ozone generator manufacturer and can review these numbers with you. The custom ozone generator manufacturer discussion becomes easier when your flow, gas, and cooling data arrive together.
Matching a 50g/hr unit to an 8-10 m³/h irrigation flow is a flow-to-power exercise, not a guessing game. Confirm your average and peak flow, identify what your water source carries, state your treatment goal, and check that you can supply 0.3-0.8 m³/hr of cooling water and 10 L/min of clean feed gas. If those five things line up, the 50g/hr output at 80-100 mg/L concentration is a strong fit, and the 20g/hr to 100g/hr variations let you scale for smaller side streams or heavier loads. Send your flow data, water test, and site conditions to the factory, and ask directly about the specific configuration, lead time, and terms that apply to your farm.
A:Start with the flow your pump actually delivers during irrigation, then confirm it falls inside the 8,000-10,000 L/hr window the 50g/hr unit is rated for. Check that the unit’s 80-100 mg/L output concentration and 10 L/min feed gas requirement match what your site can supply, and confirm you have 0.3-0.8 m³/hr of cooling water. If your peak flow or organic load runs higher, move up to an 80g/hr or 100g/hr model rather than forcing the smaller unit.
A:Choose 20g/hr or 30g/hr when you treat a smaller side stream or dose intermittently into a reservoir across the day instead of running the full flow continuously. Choose 80g/hr or 100g/hr when peak flow exceeds 10 m³/h, when recycled or surface water carries a heavy organic load, or when you plan to inject at multiple points on one farm. Running continuously at 8-10 m³/h through one treatment point sits naturally at 50g/hr.
A:Send your average and peak irrigation flow in m³/h, whether treatment is inline or into a tank, your water source with a recent lab result if available, and your treatment goal in plain terms. Add the cooling water flow and temperature you can supply, your feed gas plan at 10 L/min, and your electrical supply details. Also ask about accessories included, MOQ, lead time, packing, and warranty so the quote is complete.
