Document type: product selection information. The illustrations on this page are AI-generated diagrams, not project photographs or specific models offered for supply.
Request separate quotations for source-water treatment, drip protection, storage and supply, and nutrient-mixing interfaces. Select modules for the actual water source, crops and irrigation zones.
First determine which modules are needed
| Module | Task to address | Inputs before purchasing |
|---|---|---|
| Source-water sampling and testing | Identify issues requiring control | Water source, season, test report and crop information |
| Protective filtration | Protect irrigation against particles and relevant clogging risks | Dripper documents, actual flow and source-water risks |
| Necessary water-quality treatment | Discuss options for issues shown in the report | Measures requiring control and the basis for their targets |
| Storage and supply | Connect demand across time periods, zones and points of use | Flow by period, pressure and site conditions |
| Nutrient-mixing interface | Define the handover point between treated water and nutrient management | Agronomic requirements, mixing equipment and measuring points |
Record both water quality and hydraulic conditions in the selection table
Filter selection should consider water analysis, drip equipment and maintenance conditions.[R4] The selection table should therefore collect flow, available pressure, backwash conditions, dripper model and source-water risks, rather than only planted area in mu or greenhouse area.
Record EC, pH and alkalinity separately, with measuring points and units. The grower should provide crop, growth-stage and substrate conditions.[R2] Whether RO or other treatment is needed should then be discussed against test results and objectives, rather than treating an equipment package as the default for every growing project.
Eight items to confirm before supply
| Item | Include in the documents for this order |
|---|---|
| Treatment task | Which measure or operating issue each module addresses |
| Actual conditions | Water source, zone flow, available pressure and time periods |
| Equipment identity | Manufacturer, complete model and document revision |
| Filtration and backwashing | Rating notation, control method, backwash conditions and drainage |
| Controls and measuring points | Sampling and instrument positions, including EC/pH, and calibration arrangements |
| Storage management | Volume, usable range and maintenance arrangements |
| Nutrient-mixing interface | Who is responsible for the nutrient programme and equipment integration |
| Delivery acceptance | The conditions under which each module’s task is confirmed complete |
Make service handovers easier
Have water-treatment, irrigation and growing-management personnel confirm their respective responsibilities, then coordinate through the same monitoring-point record table. Completed equipment commissioning does not automatically establish crop performance or cut-flower vase-life effects.
The contact page on the GUDIAN Water website can serve as a common enquiry channel. Confirm supply, design coordination, installation and maintenance scopes separately for this project.
Frequently asked questions
Does every module on this list have to be purchased?
No. This is a functional checklist; actual selection depends on water quality, crops, irrigation system and site conditions.
Can a water-supply equipment supplier directly set nutrient-solution targets for every crop?
The grower and relevant agronomists must determine the nutrient programme for actual conditions. Water-treatment equipment must integrate with those requirements and cannot replace agronomic judgement.
Is a finer filtration rating always better?
Do not pursue finer filtration alone. Check dripper requirements, source-water risks, actual flow, pressure and maintenance conditions together to select a matching solution.
