Explore technical guides, application knowledge and engineering considerations for industrial water treatment projects.
Reverse OsmosisOctober 9, 20269 min readIndustrial RO recovery is a design decision, not a fixed percentage copied between projects. It links source-water chemistry, pretreatment, concentrate routing, membrane operating conditions, production demand and the owner’s tolerance for operating risk.

EDIOctober 9, 20269 min readEDI and mixed-bed ion exchange can both support high-purity industrial water duties, but they have different feed-water assumptions, operating routines and project interfaces. The right choice follows the approved point-of-use requirement and the quality of the upstream RO permeate.

EDISeptember 24, 202614 min readAn EDI water treatment system uses ion-exchange media, ion-selective membranes and direct current to continuously polish correctly conditioned RO permeate. It is a high-purity water stage, not a raw-water treatment method. Good results depend on upstream RO performance, feed-water limits, monitoring, distribution design and the agreed product-water requirement.

Pure WaterSeptember 24, 202615 min readIndustrial pure water system design starts with a verified feed-water analysis and a written point-of-use requirement. Capacity, pretreatment, RO recovery, double-pass RO, EDI, mixed bed, ultrafiltration, storage and distribution are then selected as a connected process—not as interchangeable equipment options.

Ultrapure WaterSeptember 24, 202614 min readA semiconductor ultrapure water system is a connected generation and distribution utility, not simply an RO skid. The design begins with approved point-of-use quality requirements, then aligns pretreatment, RO, EDI or other deionization, final polishing, storage, loop materials, monitoring and validation with the actual process risk.

Engineering & ProcurementAugust 31, 202612 min readA containerized pure water system is a delivery format, not a complete specification. It can reduce field assembly and simplify shipment coordination, but the process route, utilities, climate protection, access, lifting, installation interfaces and commissioning plan still need to be defined for the destination site.
Read ArticleReverse OsmosisAugust 31, 202612 min readChoose the treatment route from the required point-of-use water quality and the real feed-water analysis—not from a generic machine name. Single-pass RO is often an efficient starting point; double-pass RO adds a second desalting barrier; RO + EDI is used when a stable, low-conductivity polishing stage is required.

Reverse OsmosisAugust 31, 202611 min readIndustrial RO sizing is a water-balance and risk-management exercise. Start with the point-of-use demand profile, then work backwards through storage, distribution, RO permeate flow, recovery, feed flow and pretreatment. A quoted m³/h figure is incomplete unless its temperature, feed-water quality and recovery assumptions are stated.
