PRIMARY BUSINESS
Four business areas, each with a distinct engineering entry
Start with the project need, then move into module selection, process routes, and supporting references.
Tubular Membrane Modules
Screen membrane material, pore size, channel, temperature, and cleaning conditions for the duty.
Tubular Membrane Process Solutions
Combine membrane sections, circulation, CIP, instrumentation, and controls around a defined engineering problem.
Industrial Wastewater & ZLD
Connect pretreatment, salt fractionation, concentration, and resource recovery in a verifiable project route.
Process Fluid Separation
Clarification, purification, decolorization, concentration, and recovery of valuable components from production fluids.

CORE TECHNOLOGIES
Core technologies across pretreatment, salt fractionation, and concentration
These technology sections are selected according to feed chemistry and project objectives; the homepage does not present them as a universal flowsheet or performance guarantee.
01
PEK Tubular Membrane Pretreatment
Establish a robust solids-separation boundary for high-SS, oily, and high-fouling streams ahead of NF, RO, or ZLD sections.
02
Continuous Ultrafiltration & Nanofiltration Fractionation
Configure UF and NF around selective solute separation and the actual salt system; rejection boundaries depend on feed data and test results.
03
HRCC Continuous High-Recovery Concentration
Define continuous concentration and scale-up around upstream pretreatment and the downstream resource-recovery objective.
PROJECT REFERENCES
Support engineering screening with public project facts
Customer names remain anonymous. Capacities are shown as public project records, while new-project design values depend on the submitted duty.
PEK Softening
Reclaimed-water and Phase-I RO-brine softening reference
235 m³/h reclaimed water · 106 m³/h Phase-I RO brine
Process Fluid Separation
Lactic Acid Nanofiltration Purification
20 m³/h · reference for a 50,000 t/a production line

RESOURCES & PROJECT PREPARATION
Prepare the information needed for technical review
Review the company and product resources, then provide feed quality, flow, and the target duty to support an efficient preliminary assessment.
NEXT STEP
Explore a route by project need, or submit the duty directly
Provide the industry, flow, feed type, target use, and available water-quality data for an initial route assessment.
