One of the common problems in STP plants in India is the sheer lack of them and secondly, it is the inefficient operation of the plants. Too many plants in India fail within the first few years because these are not managed well. The reason lies mainly in the mismanagement of the plants, the lack of understanding of its operations and the lack of vision.
However, it is crucial that we pinpoint these challenges. With a critically depleting supply of water and an exploding population, the management of wastewater through STP cannot be ignored by either the public or the private sector. Understanding the challenges will go a long way in solving the challenges for STP plants manufacturer India:
Lack of training
STP plants today can come in pretty complicated mechanisms. Some of these use complicated technology that needs regular monitoring. Unfortunately, most personnel on the STP plants are rarely trained to handle such hi-tech plants. Even those who are trained are rarely given regular training on updated processes.
Typically, every plant must have staff with some basic working knowledge, someone with advanced knowledge and access to expert help. At the very least every member of the staff, including the operator and the supervisor, must have the working knowledge of the plant. They must know how to operate it, the role of each part, preventive mechanisms installed and the warning signs that indicate any malfunction.
After this come the advanced knowledge personnel. These are people who can troubleshoot the moment something goes wrong. This staff is trained to take immediate action in case of any trouble. Supervisors, in charge of the running of the plant, must have at least this advanced knowledge.
Finally, we have the experts who know the ins and outs of a plant. Because large plants that cannot afford to stay inactive for long, such experts must be on ground and accessible at all times. Smaller plants may keep someone from the STP plants manufacturer India on consultancy basis. These are usually the engineers or plant experts at the site. Experts are necessary to see that complex treatments procedures are carried out as per the plant’s parameters and in ensuring regular maintenance.
Lack of plant monitoring
STP plants need careful and regular monitoring at all times to ensure that the right conditions are met for plant operations and to see that it is working in the way it is meant to. Given the deplorable condition of feed water in most plants in India, the inadequate monitoring of the plants is dangerous.
This requires constant monitoring of feed water, especially the silt density index, pressure drop at different stages, normalized permeate flow and the percentage of salt rejection. These parameters are related to the supervision of the feed water, impurities that are found, the performance of the membrane, the percentage of fouling, the salt rejection and so on.
These are important parameters that give us an indication of the efficiency of the plant, its daily working. Regular monitoring is essential to ensure that any fluctuations are spotted immediately. Lack of monitoring will ensure that these signs are not caught in time, the performance becomes well below par and the plant eventually fails.
When it comes to STP plants, one size does not fit all. There are many parameters when deciding the type of plant suitable for a particular population or location. These include the population levels, level of water fouling, type of feed water, budget, space and so on. There are other factors that must be included to ensure that the plant uses its resources in the best possible manner and allows for easy monitoring.
The plants also need comprehensive instrumentation. This is important for both operational and monitoring of its functions. Different instruments are used to monitor feed water temperature, pressure, conductivity as well as permeate pressure, flow rate and conductivity. Plant design should not just allow for monitoring, but also facilitate regular cleaning.
This can be easily solved by hiring an expert STP plants manufacturers India. Alternatively, you must approach experts on STP plants, designs and operations. There are new methods and the requirements for personnel, design and training are changing all the time.
Sewage on board ships must be treated prior being discharged to the sea. For this, ships are loaded with STP plant that is used for treating the sewage and making it less harmful for the sea. Engineers are having better knowledge about operating the sewage plant prior using the same to comply with the rules and regulations of discarding sewage. A marine engineer should possess these things:
There are important terms that marine engineer should know. We will discuss them in detail.
Biochemical oxygen demand is a test used by engineers to determine decomposable substances and to test the sewage strength. Biochemical Oxygen Demand depends on the activity of bacteria inside the sewage. These bacteria consume organic matter under oxygenated environment.
It can be also explained as the amount of oxygen needed by micro-organisms in the organic matter stabilization.
Coliform is an organism present in human intestine and is also used as indicator organism of sewage pollution. If this organism is present in the water, it reveals the pathogen count, which are disease causing bacteria and responsible for dysentery, cholera, typhoid, etc.

There are dissolved solids, suspended solids, settle able solids, suspended level of raw sewage, and residual disinfectant. Dissolved solids cannot be seen through eyes but contaminate water.
Suspended solids are visible and can be removed by filtration process. These solids are high in organic matter.
Settle able solids will subside in quiescent liquid for about one hour.
Residual disinfectant should be low after treatment.
Biochemical digestion of sewage involves two processes- Anaerobic and aerobic processes. Anaerobic bacteria can grow in the absence of oxygen in air as they use chemically bound oxygen for survival. The bacteria break down the organic matter into water, methane, carbon dioxide, hydrogen sulphide, and ammonia. This process is known as putrefaction.
The products form out from the process are noxious and toxic. The effluent is quality less and by-products are extremely corrosive.
Aerobic bacteria need air for oxygen to survive. These bacteria break down the organic matter to generate safe products like carbon dioxide, water, energy, and inert residue to synthesize new bacteria.
These are the key terms used for STP plant on the ships. If you think we have skipped anything important, let us know in comments. Do feedback and ask if you have any confusion.
Pollution in its broadest sense inculcates all transformations that affect natural environment and put bad impact on life. The crisis hit by the continuously growing population and formation of industries that result in environment degradation. As per the packaged sewage treatment plant manufacturers, environment degradation is now a great threat to the quality of life. Water quality degradation is the unfavorable alteration of the chemical, biological and physical properties of water that prevents commercial, domestic, agricultural, industrial, and other beneficial uses of water.
Sewage and its effluents are the key causes of water pollution. Sewage is critically composed of human fecal material, industrial waste and domestic waste.
In a country like India where many parts of the country face draughts and face severe shortage of water, wastewater treatment plants act as a saviour. Wastewater Treatment India helps treat waste water and generate reusable water which in turn helps in using the waste water in various ways and also produce fertilizer which can be used as nutrients for the plants.
There are various ways by which water can be treated; in India it’s the municipal corporation which undertakes waste water treatment with the help of various Wastewater Treatment companies in India. The entire process of waste water treatment is quite complex and requires setting up of water treatment plants.
