Plants that handle about 1 to 250 Kilo Liters per day as called small sewage water treatment plants. They can be easily placed in underground tanks and existing septic tanks. Operating and maintaining these small plants are quite easy and have a low running expense as well and the treated water from this plant can be used in flushing, after using disinfecting chemicals.

Many new buildings are occupied in an incremental manner which may take years to achieve full occupancy. With this in mind, the buildings should install a Modular Sewage Treatment Plant by planning ahead on the occupancy. Other than this, we have mentioned a few reasons why it will be beneficial:

• Individually operated reactor tanks
• Timed aeration process
• Biological treatment process with Activated Sludge
• Intelligent control over the whole process

Sewage treatment plant functions with an air supply in a given time in a certain volume and flows to remove a certain quantity of pollutants. When there is a new regulation the newly applicable standards should be applied to the design and the respective volume, time of retention and the air supplied should be adjusted to achieve the new treatment standards. Tertiary treatment is only to polish the treated water to give an improved aesthetic appearance, while secondary treatment is where the real treatment happens.

There are lots of vendors, consultants, and companies that are recommending ultrafiltration to have a better quality of water, which is nothing but a white elephant for the customer.
