Dissolved Air Flotation
The Dissolved Air Flotation unit from Wuxi Dajiang Environmental Technology Co., Ltd. is a wastewater treatment system that uses fine air bubbles to separate suspended solids, oils, and colloidal matter from aqueous streams. The system operates by saturating water under pressure with air, then releasing it at atmospheric pressure to generate microbubbles of 20 to 100 microns in diameter. These bubbles attach to contaminants, reducing particle density and causing them to float to the surface for mechanical skimming.
The unit can be configured with coagulation and flocculation dosing systems, gas-tight covers, and high-efficiency air saturation pumps. Typical removal efficiencies exceed 90% for TSS and 85% for oils and grease, making it suitable as a polishing step after primary treatment like CPI. The system is constructed from carbon steel with epoxy coating or stainless steel 316L for corrosive environments. Standard flow rates range from 5 to 500 cubic meters per hour.
This system is purchased by municipal wastewater plants, food and beverage processors, petrochemical refineries, and textile manufacturers requiring advanced effluent polishing. Buyers typically specify custom configurations based on influent load and discharge limits. Units are shipped disassembled for container transport. Trade terms include FOB Shanghai, with lead times of 6 to 8 weeks after engineering confirmation. Payment is usually via T/T 40% advance, 60% before shipment.

Sourcing Dissolved Air Flotation from Wuxi Dajiang Environmental Technology Co., Ltd. - China Import Guide
Before ordering, verify the system’s design parameters against your influent characteristics, including TSS concentration, oil content, pH, and flow variability. Request performance test reports under simulated conditions. Confirm material specifications for the tank and piping, especially if handling corrosive or high-salinity wastewater. Do not accept generic efficiency claims without supporting data.
Confirm Incoterms, lead time, and payment terms in writing. Standard lead time is 6 to 8 weeks after engineering approval. FOB Shanghai is typical; CIF requires clarification on insurance scope. Payment is usually 40% advance, 60% before shipment. Ensure the unit is disassembled for container shipping and that all components are labeled for reassembly.
Upon delivery, inspect for transport damage, missing components, and coating integrity. Verify that all piping, pumps, and scraper mechanisms are intact. Conduct a commissioning test with clean water to check bubble generation and skimmer function. Request a calibration certificate for pressure gauges and flow meters. Retain all documentation for compliance with environmental discharge permits.
