Frequently asked questions
- What does this water treatment calculator estimate?
- Peak system flow (m³/h), filtration duty and typical filter selection (sand/disc/screen), UV reactor sizing based on required dose and UV transmittance (UVT), and RO permeate/feed flow with an indicative membrane count. All fields remain editable.
- Which agricultural applications is it suitable for?
- Open-field drip irrigation, greenhouse and hydroponic feedwater, nursery and propagation facilities, fertigation head-works, and cold-storage or packhouse process water pre-treatment.
- How is UV reactor sizing estimated?
- Required dose (mJ/cm²) is combined with a UVT-based transmittance factor to derive an indicative electrical demand per m³/h; total lamp power scales linearly with flow. Final selection depends on validated reactor curves from qualified manufacturers.
- How is RO membrane count derived?
- Feed flow = permeate flow ÷ recovery. Membrane count = permeate flow ÷ per-element permeate rate (typical 0.5–1.2 m³/h for 8-inch BW elements). The tool is a first-pass screening — full projection requires feedwater analysis and a manufacturer projection program.
- Is this a bankable engineering study?
- No. It is an early-stage sizing screener. For tenders, financing, or EPC contracts, SeedMatchGroup pairs the output with a full engineering package and normalised RFQ to qualified global suppliers.
