Salinity
Electrical conductivity and dissolved salts affect crop water uptake and the required leaching and blending strategy.

QUICK ANSWER2×
Two approvals are required: the treatment design and the crop-water specification.
SEAMASTER engineers the treatment platform from the source and required output. The final irrigation-water target must also be approved against crop, soil, climate and irrigation method.
IRRIGATION WATER QUALITY
Six factors must be read together.
A single TDS or conductivity value cannot describe the complete agronomic or treatment risk.
Sodium relationship
Sodium must be interpreted with calcium, magnesium, alkalinity, soil conditions and infiltration risk—not as a standalone value.
Specific ions
Chloride, boron and other ions can become limiting for sensitive crops even when total salinity appears acceptable.
Scaling chemistry
Hardness, alkalinity, silica, pH and temperature influence pretreatment, recovery and concentrate behaviour.
Emitter protection
Suspended solids, iron, manganese, biological loading and precipitates can obstruct drippers and distribution equipment.
Crop & soil response
Crop variety, growth stage, root zone, soil drainage, climate and irrigation method determine the usable final-water specification.

PRELIMINARY CAPACITY LOGIC
Production follows daily treated-water demand.
Field flow and RO production are separated by storage. These are illustrative calculations before reserve and agronomic review.

BLENDING & NUTRIENT STRATEGY
Maximum salt removal is not automatically the agronomic optimum.
Where the raw water contains usable minerals but one or more limiting constituents, controlled blending may reduce treated-water demand and stabilise the final composition. The blend must still satisfy every crop, soil and emitter constraint.

IRRIGATION APPLICATION FAQ
Questions that protect crop and system.
01Can irrigation suitability be decided from conductivity alone?
No. Conductivity describes overall ionic loading but does not show specific-ion toxicity, sodium-related infiltration risk, scaling tendency, emitter fouling or crop and soil sensitivity. Review a complete water analysis with the agronomic conditions.
02Does RO permeate always need remineralisation or blending?
Not always, but very low-mineral permeate can change nutrient formulation, alkalinity, pH stability and corrosion behaviour. Blending, remineralisation or fertiliser adjustment must be decided from the crop, source water, irrigation system and agronomy plan.
03Should the RO plant match the irrigation pump flow?
Usually not. Irrigation can require a high flow for a short zone cycle, while the RO plant produces steadily into storage. Size the RO system from the total daily treated-water demand and available production hours; size storage and irrigation pumping from the field schedule.
04Can concentrate be reused for irrigation?
Do not assume it can. Concentrate contains the rejected salts at a higher concentration and may create crop, soil, groundwater or discharge risks. Any reuse requires a separate water balance, analysis, agronomic assessment and local environmental approval.
05Are the product-family conductivity limits crop limits?
No. They are catalog feed-water boundaries for preliminary equipment routing. The acceptable irrigation-water composition is a separate agronomic decision based on crop, soil, climate, irrigation method and blending strategy.
