How to clean and maintain a STP Plant?
Sewage treatment plants are a crucial component of water and sanitation facilities. They are put in place for collecting wastewater from residential or commercial buildings and treat it to purify the organic matter and remove pollutants. Following the rules set forth by the environment agency and preserving public health depend on the safe and ecologically responsible discharge of the treated effluent to groundwater.
Working principle of STP:
various physical, chemical, and biological treatment methods are used in sewage treatment plants to accomplish their tasks. Most of the time, a typical sewage treatment facility will start with preliminary treatment using screens and/or grit chambers to remove bulkier, heavier, frequently inert organic matter. Primary settlement containers are used after that to get rid of less dense solid matter.
When the water exits these processes, it should be clear of particles and fed into a biological treatment step, where high-density microbial communities break down the carbon and nutrients in the water. Before returning to open water bodies, the disinfected water may occasionally be treated with UV light or chlorine.
What are the difficulties dealing with STP?
In a sludge treatment plant, sludge is constantly generated. After being processed, the sludge is typically disposed of as wastewater. STP management can be difficult because there are so many details that need to be handled.
In STPs, issues with odor, overflow, and abrasion occur. The system was subjected to abrasion due to the sand particles, which were either excessively coarse, too sharp, or both. When some factories didn't have enough space for all the sludge they created, they also faced downpours. Let's now examine how these sludge issues in a sewage treatment facility might be prevented.
Cleaning and maintenance of STP:
It is crucial to maintain and repair sewage treatment facilities, and there are numerous small-scale sewage treatment plants constructed all over with various designs and sizes. Keeping the sewage treatment plant properly maintained and serviced is one of the main measures to prevent pollution. It is well known that many household sewage treatment facilities are neglected until they malfunction or pose a pollution problem.
The minimal maintenance needs for sewage treatment plants depend on the size, type, and age of the system. Typically, once or twice a year should be allotted for servicing and upkeep of sewage treatment facilities up to 18PE. Commercial sewage treatment facilities might need to be serviced more frequently.
All sewage treatment facilities are built to encourage the growth of aerobic microorganisms, but the approaches taken to generate and maintain these environments vary greatly.
Processes used in sewage treatment facilities include the utilization of air blowers, rotating discs, submersible pumps, and filter material. Every sewage treatment facility needs routine maintenance, and the maintenance needs mostly rely on the kind of treatment method being applied.
Cleaning of STPs:
STP tank cleaning services which includes six stages of cleaning services which are as follows
? Removal of wastewater
? Pretreatment level
? Primary treatment stage
? Secondary treatment level
? Final settlement
? Sludge treatment
Maintenance of STPs:
Even a good STP would need desludge and maintenance at least once a year, while low-budget STPs require regular cleaning and monitoring. It needs to be quickly filled up with water after desludging in order to balance the pressure inside and outside.
Rainwater must never, under any conditions, enter the STP. Flooding may result and germs may be flushed out.
Primary tank and soakaway emptying must be handled on a regular basis by society, not by the manufacturer's support team.
Below components should be checked during maintenance visits:
· Unobstructed, strong and efficient blower and ventilation
· Mechanical components replacement if needed
· Inspection for air filters and pipes inspection
· Diffuser inspection for bubbles
· Biomass color and smell check
· Final effluent quality
· Damage repair in all chambers
· Lid seal integrity
· Replacement of diaphragms and valve boxes
Using sewage from public drains, sewage treatment facilities create clean, odorless water that is suitable for drinking and bathing. All of the water we get from the tap is recycled, and the final steps of treatment are applied to the drinkable water.
Modern sewage purification facilities are highly automated, which boosts plant efficiency and lowers the possibility of human error. Without human involvement, networks, sensor technology, and automatic controls keep plants running.
