Habulay Brine Evaporation Test

1.0 litre of Habulay saline water yielded 350 grams of pan-dried crystal salt

To confirm physical salt recovery ahead of lined pilot pond construction, Noolays evaporated a measured 1.0-litre brine sample from the Habulay Saline River Basin (Dihun Woreda, Nogob Zone), recovering 350 grams of crystalline salt weighed after pan-drying.

Test summary

Record NSP-EVAP-2026-01

Developer	Noolays Salt Producer Cooperative
Resource Location	Habulay Saline River Basin, Dihun Woreda
Date Recorded	21 October 2026
Brine Volume	1.0 litre (1,000 mL)
Pan-Dried Yield	350 grams crystal salt
Dissolved NaCl Basis	~318 g/L (near-saturated brine)

Commercial advantage

Why High-Salinity Feed Matters

Coastal seawater saltworks require ~85–90% of their land area solely to concentrate dilute seawater (~35 g/L) up to saturation. Starting with hypersaline continental brine dramatically reduces primary pond area, accelerates harvest cycles and lowers capital expenditure per tonne.

Ocean Seawater~35 g/L

Habulay Survey Baseline>250 g/L TDS

Habulay Brine Test~318 g/L NaCl (350 g pan-dried)
