Treatment systems

Match the method to measured conditions.

Treatment technologies solve different problems. A responsible recommendation also considers concentration, flow, pressure, maintenance and verification.

MethodCommon roleImportant considerations
Sediment filtrationSuspended particles and pretreatmentParticle size, loading, pressure loss and replacement frequency
Oxidation and filtrationSelected iron, manganese and sulfur conditionsWater chemistry, contact time, backwash flow and contaminant form
Ion-exchange softeningHardness and selected dissolved ionsCapacity, salt, regeneration, iron loading and wastewater
Activated carbonSelected organic compounds, taste and odorMedia type, contact time, certification, exhaustion and microbial control
Ultraviolet disinfectionMicrobial inactivationPretreatment, UV dose, lamp/sleeve maintenance and power
Reverse osmosisPoint-of-use reduction of selected dissolved contaminantsFeed-water quality, rejection claims, wastewater, storage and verification
NeutralizationLow pH correctionMedia consumption, hardness increase, flow and target pH

Whole-house treatment

Treats water entering the home. It often requires higher flow, plumbing work, drainage and a larger maintenance plan.

Point-of-use treatment

Treats water at a specific tap. It can be appropriate when the concern is primarily ingestion and whole-house treatment is unnecessary.

Treatment trains

Some wells need sequenced stages, such as sediment control before UV or oxidation before polishing. Order matters.
