Typical cases

Reference cases from the current Haitron website, rewritten into a cleaner technical proof format for buyers and engineers.

Resource recoverySelective recovery path

Potassium Extraction from Concentrated Seawater

A strategic resource-recovery case focused on separating potassium from concentrated seawater and brine-like streams where selectivity matters more than simple ion removal.

Resin directionChelating direction

ChallengeHigh salinity streams contain competing ions that make conventional removal inefficient and commercially weak.

Approach

Use a selective resin direction, validate ion competition with feed analysis, then confirm regeneration and recovery economics before scale-up.

Seawater desalinationWHO / drinking-water compliance

Boron Removal in Seawater Desalination

Seawater RO permeate typically carries 0.5 to 1.5 mg/L boron, above the WHO guideline of 2.4 mg/L and well above stricter local limits (0.5 mg/L in some regions). Boron-selective resin polishes the permeate to meet these targets reliably.

Resin directionBoron-selective resin

ChallengeBoron passes through RO membranes more easily than most ions due to its small, uncharged molecular form at neutral pH. Seasonal temperature and salinity shifts in the feed further reduce membrane rejection, making a dedicated polishing step necessary.

Approach

Install a boron-selective ion exchange bed downstream of the RO stage. Validate resin selection against permeate boron concentration, target outlet limit, pH, temperature, and regeneration chemical. Confirm breakthrough profile and bed life before commissioning.

RO protectionMembrane protection

Groundwater RO Membrane Pretreatment

A pretreatment case for groundwater systems where resin selection protects downstream RO membranes from hardness, scaling pressure, and unstable feed conditions.

Resin directionSAC / WAC support

ChallengeUncontrolled hardness and ion load reduce membrane life, increase cleaning frequency, and make system performance less predictable.

Approach

Use resin pretreatment to stabilize the feed stream, then confirm resin family and model against hardness, alkalinity, flow rate, and regeneration capacity.
