Sewage treatment plants primarily make use of bacteria and other microorganisms for the treatment of water. These plants make use of a number of chemical and physical methods such as hollow fiber membrane, and a range of membrane filter techniques for the treatment of sewage and wastewater.
As far as a typical biological sewage treatment plant om China is concerned, there are a number of operational challenges that can be present in the plant. The major challenge is that of energy consumption.
Indeed, energy consumption is one of the biggest expenses of a typical biological sewage treatment plant. It has been estimated that the sewage treatment consumes around two to three percent of a nation’s electrical power.
One of the best methods to reduce these costs is to reduce the demand for energy in a treatment plant. In this regard, a great impact can be made by making use of the right membrane filter technique, and the right technology from a reputed supplier. For instance, Hydro Blue Membrane Technology Co. LTD. is the highest reputed wastewater/sewage treat plant supplier in China and has been operating for a long time now.
Since Hydro Blue has been heavily involved in research and development related to wastewater and sewage treatment from a long time, the company produces a number of patented products for sewage plants. These products are optimized to reduce the energy requirements on a plant by significantly enhancing the efficiency of the process.
Another major challenge is the sludge production. A large amount of sludge is produced after the physical, biological, and chemical treatment of sewage. The disposal of this excess amount of sludge is a major challenge, especially for a country like China which is already very densely populated.
The safest and most long-term solution is to recycle the sludge, which may contain a range of useful nutrients and organic matter that can be used for agricultural purposes. A number of modern technologies are available nowadays, such as those supplied by Hydro Blue, that reduce the problems of sludge by lowering its production.
Another common problem is that of the staff. It is important for the operators at a sewage treatment plant to be trained adequately, and to be certified in their area. The staff is routinely involved in the inspection of leakages, and the maintenance of instrumentation equipment, valves, and all the electrical equipment on the facility. Operator management may account for 30% of the entire plant cost. One solution is to make use of automated technologies as much as possible. Even then, it is important to note that the need for a physical staff to be present on the plant cannot fully be removed. However, it can certainly be reduced by automating a number of major processes.
