Frequently asked questions
What is the difference between filtration and softening?
Filtration removes suspended solids and particulates from water using media such as sand, gravel, or membrane elements. Softening reduces hardness ions like calcium and magnesium, often through ion exchange resins. They solve different water quality problems and are frequently used in combination.
How do I choose between reverse osmosis and conventional filtration?
Reverse osmosis removes dissolved salts and fine contaminants at the molecular level and is used when high purity is required. Conventional filtration removes suspended solids and is less energy-intensive. The choice depends on your water quality target, feed water composition, and budget.
What standards should I check before buying disinfection equipment?
Check local health and environmental regulations, as well as recognized industry standards for disinfection performance. For UV systems, look for certifications that validate germicidal output. For chlorine systems, verify compatibility with your distribution system and any downstream material requirements.
What are the main cost drivers in wastewater treatment equipment?
Capital cost includes the equipment itself, installation, and integration with existing infrastructure. Operating cost includes energy, chemicals, maintenance parts, and labor. Equipment lifetime and downtime risk also affect total cost, so evaluate lifecycle cost rather than purchase price alone.
How do I evaluate a supplier for water treatment equipment?
Request technical data sheets, ask for reference projects, and verify that the supplier can provide installation support and spare parts. Check their quality control processes, lead times, and whether they have experience with your specific application.
What documents should I collect during procurement?
Gather technical specifications, compliance certificates, warranty terms, installation drawings, and operation manuals. Make sure all documents are in your working language and that performance guarantees are clearly stated.
