We recommend providing a water quality report, treatment capacity, existing process, target discharge or reuse indicators, site space, and energy conditions.

You can first provide the industry, process section, treatment capacity, main pollutants, and project objectives. After initial discussions, necessary tests such as ion composition, COD, hardness, or metals can be added based on the technical route.

ED is mainly used for ion removal and brine concentration, DD is commonly used for waste acid or waste alkali recovery, and BMED is used to convert salts into acid and alkali. The final selection also depends on impurities, concentration, target products, and continuous operation requirements.

Pretreatment depends on risks such as suspended solids, organics, hardness, silica, oil, and oxidizing substances. It should be determined around protecting downstream membrane and evaporation units, stabilizing the feed, and controlling cleaning intervals.

When the material composition is complex, target selectivity is high, continuous operation data is limited, or large-scale scale-up is planned, prior validation is recommended. Bench-scale testing addresses feasibility, while pilot-scale testing further confirms fluctuations, energy consumption, fouling, and control boundaries.

The concentration of recovered materials, impurities, purity requirements, stable outlets, and downstream processing costs must be assessed together. A resource recovery solution has engineering value only when the treated output can enter a defined reuse or utilization route.

At the preliminary stage, an estimated range can be based on treatment capacity, water quality, target concentration, and process combination. Reliable data usually requires further verification using bench-scale testing or pilot-scale testing results, equipment efficiency, chemical consumption, and local energy prices.

Yes. An assessment can be carried out, but the existing process, equipment margin, interfaces, site space, control system, and shutdown window must be reviewed. The retrofit plan should define retained units, new battery limits, and operating arrangements during switchover.

Depending on the contract scope, it may cover process design, equipment manufacturing, module integration, FAT, on-site installation guidance, SAT, commissioning, and training. Specific performance indicators and responsibility boundaries should be defined in the technical agreement.

Yes. Cooperation can cover process packages, core equipment, modular systems, and remote technical services. Before project launch, local standards, supply boundaries, site conditions, language documents, and after-sales responsibilities must be clarified.
