Nanjing Lan river Treatment Equipment Co., specializing in the production QJB submersible mixer, QSB jet aerator, QXB centrifugal aerator, DSA new centrifugal aerators, various models of submersible mixers, submersible aerators Daquan, professional skills, professional quality, with a reputation to win your trust. Selection of data to be provided: 1, COD (kgO2 / h). 2, the aeration tank shape, size and depth (m). 3, the aeration tank water quality conditions (such as temperature, BOS, COD, etc.). How to order: DSA DSA series submersible aerator installation: DSA series submersible aerators are easy to install lifting, no special foundation bottom, aerators can rely on its own weight, stable place in the pond bottom, without a fixed or other device , concrete bottom of the pond and without special reinforcement. Use: DSA series submersible aerator is mainly applied to sewage treatment plants, in particular: the separation of biological oxidation of sludge digestion and alkaline wastewater, oil and grease. Advantages: light weight, diving depth, fine bubbles, easy dissolved oxygen rate, maintenance, installation, use and flexible, no requirements for pool shapes: smooth running, quiet, low noise. As the bottom of the mixing chamber to the passivation of stainless steel material, will significantly extend the service life. Run Features: DSA series submersible aerators for those in need of additional air supply of the sewage treatment process, is the most economical and most effective option. As a result of submersible motor design eliminates the need to invest in the equipment room. DSA series submersible aerator with a star impeller design, radial gas, water mixing channel, when the impeller rotates, while the intake air in the mixing chamber to form a vacuum, but with the water at the impeller agitation, the proliferation of channels, forming bubbles, the oxygen in the air into the water. Materials: Motor part: cast iron; shaft: stainless steel 420; Bolt: stainless steel 304; Impeller: 304 stainless steel; hydraulic components: carbon steel (according to user requirements to provide 304 or 316 stainless steel). DSA series submersible aerators are easy to install lifting, no special foundation bottom, aerators can rely on its own weight, stable place in the bottom of the pond, or other devices without a fixed, concrete pond bottom and need special reinforcement.
