Detailed Product Description: | Disc diffusers DESCRIPTION More microporous membrane diffuser aeration device is the latest developed in the 1980s, which means aeration bubble diameter is small, a large gas-liquid interfacial area, bubble spread evenly, will not plug the hole corrosion resistance than conventional products fixed spiral aerators, diffuser aerator and perforated pipe aerator to reduce energy consumption by 40%, or an increase sewage treatment capacity by 40%. Especially suitable for large and small urban sewage and factory construction, expansion and transformation of the old aeration tank. [Product Parameters flat, microporous membrane of spherical diffuser aerator Size: 260mm, 215mm Service Area: 0.35-0.75m2 / a, 0.25-0.55m2 / a running average pore membrane aeration: 80 -100 micron air flow: 1.5-3m3 / a h oxygen transfer coefficient: kla (20%) 0.204-0.337min-1 oxygen utilization :( depth 3.2m) 18.4-27.7% oxygenation capacity: 0.112-0.185KgO2 / m3h oxygenation power efficiency: 4.46-5.19KgO2 / kwh Aeration resistance: 180-280mmH2O product features film of all imported material (EPDM) low resistance film easily open aeration service area is large and smooth off the sludge aeration membrane tablets in sufficient quantity to extend mechanized assembly surrounding the overall strength of robust sealing performance and long service life maintenance and clean-up [of] disc disc aerator aerator maintenance: the diaphragm should be checked after a continuous operation by the operator, especially if continued use may produce pressure loss increases, or becomes bubbly rough shape. The latter leads to significantly lower oxygen transfer efficiency, because only part of the perforated zone excessive aeration. Diffuser should be noted that according to periodically remove sediment (carbonate, iron, aluminum, biological slime, etc.). These deposits increase depends on a specific operating condition wastewater and wastewater treatment plants. When the aeration tank is closed and emptied, the post or aeration device can improve the unit lifted, should ensure that the sludge will not precipitate on the membrane is dried and solidified. If the precipitate is dried film would undermine diffuser normal function. Clean up the aeration plate: a, biological precipitate mechanical cleaning recommended clean-up program is to use physical exclude its product, either by gently brushing, you can use high-pressure water jet cleaning machine wash 1) diaphragm and nozzle. the distance should be maintained between about 50 cm, in order to avoid too intense jets of water damage to the diaphragm. When phosphorus precipitation may not use pure pure aluminum sulfate and ferric sulfate, used chemical treatment diaphragm material. Detachable strong adhesive precipitate using a high pressure water jet cleaning machine washed away. b, chemical cleaning / OSHA specifications MSDS2) common method of chemical cleaning of calcium carbonate scale is an air flow acid detection. Using this process, the aeration tank may not be required drainage. Depending on the degree of the deposition surface of the membrane, the concentrated formic acid (85% by volume) should be added twice a year, the commercial-grade air flow into the metering pump. The air flow rate of each diffuser is adjusted to the maximum, in one hour, in each aeration pan add about 100 cm3 / 3.4 fl. Oz. (Fluid ounces) of formic acid. In order to subsequently remove acid from the system, a constant air flow rate rinse for at least two hours. The exact amount depends on the ratio of the degree of deposition, waste composition and working conditions, etc., the optimum amount required is determined by a variety of suitable methods. Pipes, valves and fittings connectors must be acid-resistant. Do not allow the use of chemicals and additives, the use of chemicals and additives will void your warranty commitments. 1) Follow pressure washer manufacturer's safety guidelines. 2) formic acid is dangerous and may lead to serious injury and death. It requires specialized equipment and training professionals. The use of formic acid to follow all safety guidelines. Yue Gongyi City Water Treatment Materials Co., Ltd.
