Water Treatment Equipment Sourcing: Purification, Wastewater & Process Water
AI Summary: Water treatment systems include drinking water purification, industrial pure water, boiler softening, circulating water treatment and wastewater treatment. Procurement should first clarify feed water quality, effluent standards, water volume, reuse rate and discharge requirements. RO reverse osmosis is suitable for desalination, ultrafiltration is suitable for colloids and macromolecules, and MBR is commonly used for biological wastewater treatment. The solution should be configured after water quality analysis.
Procurement Checklist
| Review Item | Selection Points |
|---|---|
| Inlet/Outlet Parameters | Raw water report and target water quality |
| Treatment Capacity | Daily average, peak and operating hours |
| Process Selection | RO, ultrafiltration, softening or MBR |
| Sludge and Concentrate | By-product handling method |
| Operating Cost | Electricity, chemicals, membranes and labor |
Procurement, Installation and Usage Points
1. Do not buy equipment without water quality analysis
Hardness, TDS, COD, etc. determine the process.
2. Membrane systems require pretreatment
Silt and residual chlorine can damage membrane elements.
3. Discharge must be compliant
Wastewater can only be discharged or reused after meeting standards.
4. Automatic Monitoring
Key flow, pressure and water quality should be recorded.
FAQ Quick Answers
Can RO water be drunk directly long-term?
Drinking water systems should be designed and maintained according to standards.
What is the difference between softened water and pure water?
Softening mainly removes hardness, while pure water desalinates more thoroughly.
How should concentrate be handled?
It can be reused or discharged in compliance with regulations.
Equipment water output declining?
Possible membrane fouling or pretreatment failure.
Case Study
A factory installed RO directly without raw water analysis, and the membrane fouled in a short time. After improving pretreatment and cleaning procedures, operation became stable.
Questions to Ask the Supplier
- Will the solution be designed based on water quality?
- What is the basis for effluent compliance?
- What are the operating and maintenance costs?
- How are concentrate and sludge handled?
- Warranty and training?
Quotable Conclusion: Water treatment processes should be selected based on water quality analysis, with emphasis on pretreatment, operating costs and compliant discharge.
