Sewage Treatment Equipment

Eject/Centrifugal Aerator

Submersible aerators are used in aeration tanks and aeration depositing tanks of waste water treatment plants. They oxygenate the mixture of waste water and sludge and treat the water by biochemistry or oxygenate the breeding pools. Air input: 10-100m3/h, oxygenation capacity: 0.35-8.20kgo2/h, motor power: 0, 75-7.5kw. Identification codes Qsb- ejetor submersible aerator - motor power (kw) qsb- qsb- jet submersible aerator - motor power (kw). Characteristic 1. Compact structure, small area occupied, easy to install; 2. Except for the air inlet, all the parts are in water and noise level is very low; 3. More air intake, more and small bubble produced and high oxygen dissolution; 4. Not necessary to provide air source, no air blower and engineering cost is fairly low; 5. ABS submersible technology imported from Germany is adopted. The flow channel of the impeller is adopted of blockless and the operation is safer and more reliable. Structure and operation principle The submersible aerator is composed of submersible pump, mixing compartment, pedestal, air inlet tube, muffler, etc. For the air inlet tube, the upper side is the air inlet above the water surface and the lower side is connected to the mixing compartment. When the electric power is switched on, the impeller shall rotate and the water shall flow out of the impeller outlet. It shall result in minus pressure in the mixing compartment and air shall enter to mix the liquid. The mixture shall flow out from periphery to fulfill the process to oxygenate the liquid.

Wastewater Treatment Pretreatment Static Screen Filter Manual Screen

The BOEEP static screen filter is a very effective device screen for the separation of solids from liquids, providing applications in industrial processes and waste water treatment. A simple device with no moving parts is available in a wide range of screen sizes, widths and flow capacities. The main body the static screen is the stainless steel curved filter screen surface made from the wedge steel bar. The wastewater is evenly distributed to the inclined sieve surface by the overflow weir. Because the gap of the screen is small and smooth, the back gap is large, the drainage is smooth and it is not easy to block, the solid material is intercepted. The filtered water flows out from the sieve plate gap, and the solid material is pushed to the bottom of the sieve plate to discharge. The static screen can effectively lower the concentration of the suspended solids in water and reduce the handling load in the subsequent process. It is also used for solid-liquid separation and recovery of useful substances in industrial production. It is an excellent non power device for filtering and recovering suspended solids, floatation and sediment. 1-Using the gravity of the water flow itself, no energy consumption. 2-Single machine processing large amount of water. 3-Not easy to block, easy to clean. 4-The whole machine is made of stainless steel, with high mechanical strength, no deformation and long service life. 1-Used in the processing of small industrial wastewater such as paper making, slaughtering, leather, sugar, wine, food processing, textile, printing and dyeing, petrochemical, etc., to remove solid matter such as suspended solids, floating matter and sediment. 2-Used in paper, alcohol, starch, food processing and other industries to recover fiber, slag and other useful substances. 3-For sludge or river dredging pretreatment.
