Efficient shallow air flotation machine

The high-efficiency shallow air flotation device integrates condensation, air flotation, skimming, sedimentation and mud scraping. The whole is cylindrical, compact structure, shallow pool. The main body of the device consists of five parts: pool body, rotating water distribution mechanism, dissolved air release mechanism, frame mechanism, water collection mechanism, etc. The water inlet, water outlet and scum discharge outlet are all concentrated in the central area of the pool body. The water distribution mechanism, water collection mechanism and dissolved air release mechanism are closely connected with the frame and rotate around the center of the pool body. This device provides a complete set of equipment assembly and control system, through the combination of centralized control and decentralized control, so that the equipment to achieve the best operating state. The use of RQF shallow air flotation equipment In the water treatment process, solid-liquid separation technology and its equipment are one of the key items. Air flotation is one of the most effective methods for the removal of tiny suspended particles with a specific gravity close to that of water.

Product Details

Product Introduction

Product Features

The purification pool is shallow, but there is enough scum storage space, especially suitable for the treatment of high concentration sewage;

Large processing capacity, small footprint, no footprint, overhead, stacked or set on the building;

The water level and scraping depth are adjustable, the flow adaptation range is large, and the scum scraped is high in solid content;

Assembled structure for easy transportation, installation and relocation;

The rigidity is large, only one "well" shaped concrete beam support is required, no platform is required, and the civil construction cost is low;

There are three types of carbon steel (key parts stainless steel), partial stainless steel and full stainless steel. Carbon steel after all the first grade sandblasting by special heavy anti-corrosion treatment, can acid, alkali corrosion, the use of ten years in good condition as new.

Rotary joint adopts high-tech patented technology, no maintenance, wear and adjustable, long-term operation without water leakage, is a permanent design.

The moving parts are provided with multiple protections for long-term reliable operation in the open air.

Because the microbubble diameter is very small, the density is very high, can fully capture very small suspended solids, do not need to condense them into a large alum flower in advance, it can greatly reduce the dosage, some occasions even can not be put into operation, greatly reducing the operating cost.
