How to deal with the growth of bacteria and algae in circulating cooling water?

The circulating water due to nutrient concentration, water temperature and long time in the summer sunshine, to create the rapid propagation of bacteria and algae. The condition of a large number of bacteria secrete mucus mixture, can make the water floating dust bonding impurities and chemical precipitate together, forming sticky sediment biological sludge attached to the host the heat transfer on the surface of the condenser (heat exchanger and filler cooling tower in addition, caused by corrosion under the scale), the circulating water flow is reduced, reducing the heat exchange efficiency, increase the power consumption and the load of the main frame, which can clog pipe.
The harm of against bacteria and algae, alternately adding different types of 2 kinds of biocide antibacterial cleaning agent, these fungicides against various bacteria, algae with broad-spectrum killing of targeted, reducing the acid formation of nitrogen-containing compounds; a month or twenty days cleaning a cooling tower, the total number of bacteria was 105 /ml. Usually, the effective control of corrosion of circulating water, the premise of fouling and biological slime and other hazards, it is possible to run in high concentration, so as to obtain the maximum water saving water treatment and the best economic benefit. The water cooling circulating water is tap water, tap water moderate hardness, low alkalinity, have certain scaling tendency and strong corrosion resistance. In the process of water circulation, cooling water by evaporation concentration. When the concentration increased to 7 times less than the sewage water and supplement water decreased rapidly, day The effect of water is obvious, but the concentration is increased, and the scaling of water is enhanced. Therefore, scale inhibitor is needed to prevent scaling

Can be cleaned. Cooler fouling is generally divided into tube fouling and tube fouling of two, due to the circulating water with soft water, so the pipe scaling generally does not appear, unless you first use of circulating water is not water, cleaner again use soft water circulation. Most cooler fouling is outside the pipe scaling the reason, there are two types, one is in the circulating water i...

  • 1.Central air conditioning yellow water how to do?
    A:
    Central air-conditioning chilled water and condensate water are recycled water, the cycle will be adsorbed in the air of dust, foreign bodies, etc., water will generate microorganisms, so require regular replacement of water, if dirty very interested, or even to add special cleaning agent Cleaning; if condensation in the condenser more scale, will result in cooling effect of central air conditioning decreased, electricity consumption increased, so also regularly open the cleaning condenser. The way to do this is to change the frequency of cooling water and condensate and to clean the condenser……
  • 2.Circulating cooling water algae growth in a lot of how to deal with?
    A:
    Circulating water due to nutrient concentration, temperature and summer prolonged sunshine, bacteria and algae to create a rapid breeding conditions. Much like the mucilage secreted by bacteria, it allows dust and chemical buoys floating in the water to bond together to form slimy sediments. A biofouling sludge attaches to the heat transfer surfaces of the host condenser Heat transfer filler), in addition to causing corrosion under the scale, but also to reduce the flow of circulating water, reducing heat exchange efficiency, increase power consumption and host load, in severe cases will plug the pipeline……
  • 3.Cooler fouling can clean it?
    A:
    Can be cleaned. Cooler fouling is generally divided into two types of tube fouling and tube fouling, as circulating water generally use soft water, so fouling tube generally does not appear, unless your circulating water is not soft water, remove the detergent first Use soft water cycle. Most of the cooler scaling is outside the tube scaling, there are two reasons for its study, first, the circulating water pipe is too high, because the spray water is generally used groundwater that is hard water, so if the tube temperature is too high will make the spray water temperature Rise, the formation of scale in the pipe wall, the second is spray water itself with high Mg and other elements, especially in mountainous areas, the water is relatively hard……
