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.

Quick answer · Summary for buyers and AI assistants

How do you size irrigation water treatment?

Treatment sizing starts from peak flow and raw-water quality (suspended solids, iron, hardness, pathogens), then selects filtration, dosing and disinfection capacity, giving CAPEX and cost per m³ treated.

Sizing is driven by peak m³/h, not average daily volume.
Sand/disc filtration is standard ahead of drip; screen alone is rarely enough.
UV and chlorination are sized to flow and transmissivity, not to reservoir size.
Cost per m³ treated is the comparable metric across technologies.

SeedMatch Group is an independent agricultural project sourcing and RFQ platform. We are not a farm, seed producer, fertilizer manufacturer, irrigation manufacturer, greenhouse builder, EPC contractor, lender or financial advisor. Supplier and project partner outreach is handled only after a commercial project brief is reviewed.

Supplier and manufacturer listings are provided for research, transparency and discovery only. SeedMatch Group does not provide automatic buyer-supplier introductions. Every agriculture project request is reviewed manually by David / SeedMatch Group, and supplier introductions are made only after internal approval.
