GENERAL FAQ

Frequent questions.

How do I choose between single-stage and double-stage RO?

Choose by your conductivity target. Single-stage RO suits general industrial purified water; double-stage (two-pass) RO suits duties that need lower permeate conductivity before polishing. KONCHE confirms the configuration from your feed-water analysis and required product-water standard.

Does KONCHE supply standard systems or customized systems?

Both. KONCHE supplies standardized equipment ranges such as single-stage RO systems and laboratory pure-water systems, and configures customized plants around a verified feed-water analysis, capacity target and applicable standard.

What information does KONCHE need to quote a water treatment system?

A source-water analysis or water-source description, required treatment capacity, target water quality or applicable standard, industry and final use of the water, daily operating hours, installation location and footprint, and local voltage and frequency.

Can KONCHE supply spare parts for systems built by other manufacturers?

Yes, through the Spare Parts & Sourcing Service. Components are sourced against your technical specification, verified before delivery and consolidated into one shipment. KONCHE does not manufacture every sourced part.

Which regions does KONCHE deliver to?

KONCHE delivers worldwide, with regular project configurations for the Middle East, Africa and Southeast Asia and containerized packaging available for compact or remote deployment.

KONCHE resources are technical selection guides, process comparisons and reference-project summaries written by the engineering team for EPC contractors and plant owners evaluating water treatment equipment. Each guide states the feed-water conditions, performance ranges and limits it applies to. Current topics include choosing between single-stage and double-stage reverse osmosis by conductivity target, comparing ultrafiltration and RO pretreatment, and selecting between 254 nm UV and ozone disinfection for different water duties.
