Side stream Filters

Side stream Filters normally used for industrial cooling tower. Cooling Towers, by design, flush airborne contamination such as biocides, heat, slime or silt into the system, where they deposit on heat exchange surfaces. Suspended matter in the cooling water also supplies living microorganisms with a constant food source for sustaining life and multiplying. Shubahm provide suitable cooling tower side stream Filter (SSF) which can remove all the physical contamination from the water which affects the life and efficiency of the cooling towers system.

Shubhamindia is One of the best Manufacturer and Supplier Of Sewage Treatment Plant in India, Gujarat, Ahmedabad, Baroda, Surat and Mumbai. We are also provide Sewage Treatment Plant (STP) in terms of Package, Conventional Sewage Treatment Plant, Prefebricated Sewage Treatment Plant and Underground Sewage Treatment Plant form.

There are areas within the cities, towns and villages that are impossible to cover under centralized wastewater treatment system, to offer perfect solution for the same, Shubham steps in this field. Shubham package stp type wastewater treatment system is compact, effective and economical for wastewater treatment in decentralized manner. PWTS-AM series is ideal for individual bungalows, low rise apartments, restaurants, offices, small factories, etc. NBF series is ideal for malls, hospitals, office building, institutions, townships/colonies, high rise buildings etc.

Operation Principle

1. Solid Separation Zone of package stp: This is the primary treatment process that separates solid and scum from wastewater.

2. Aeration Zone of package stp: Clear water flows into this stage. Oxygen supplied by air blowers is required for the digestion of bacteria culture thriving in and around the plastic media inside the aeration zone, thus reducing the amount of contaminants while generating more contacts with the bacteria culture on the surface area of media. The quality of water becomes better.

3. Sedimentation Zone of package stp: The next step of treatment involves the sedimentation where organic wastes are settled in the sedimentation zone. The settled waste in the bottom of the tank can then be pumped back to the solid separation as a return sludge to ensure that quality of effluent passes the required standard. Chlorine is sometimes introduced before discharging the effluent into public mains.

Shubhamindia is One of the best Manufacturer and Supplier Of Sewage Treatment Plant in India, Gujarat, Ahmedabad, Baroda, Surat and Mumbai. We are also provide Sewage Treatment Plant (STP) in terms of Package, Conventional Sewage Treatment Plant, Prefebricated Sewage Treatment Plant and Underground Sewage Treatment Plant form.

Conventional STP

Conventional STP involves three stages, called primary, secondary and tertiary treatment.

First, the solids are separated from the wastewater stream. Then dissolved biological matter is progressively converted into a solid mass by using indigenous, water-borne micro-organisms. Finally, the biological solids are neutralized then disposed of or re-used, and the treated water may be disinfected chemically or physically (for example by lagoons and microfiltration).conventional_STP

The final effluent can be discharged into a stream, river, bay, lagoon or wetland, or it can be used for the irrigation of a golf course, green way or park. If it is sufficiently clean, it can also be used for groundwater recharge or agricultural purposes.

Pre-treatment

Pre-treatment removes the materials that can be easily collected from the raw wastewater and disposed of. The typical materials that are removed during pre treatment include fats, oils, and greases (also referred to as FOG), sand, gravels and rocks (also referred to as grit), larger settleable solids and floating materials (such as rags and flushed feminine hygiene products).

Pre treatment also typically includes a sand or grit channel or chamber where the velocity of the incoming wastewater is carefully controlled to allow sand grit and stones to settle, while keeping the majority of the suspended organic material in the water column. Sand, grit, and stones need to be removed early in the process to avoid damage to pumps and other equipment in the remaining treatment stages.

Preliminary treatment processes include coarse screening, medium screening , shredding of solids, flow measuring, pumping, grit removal, and pre-aeration. Chlorination of raw wastewater sometimes is used for odor control and to improve settling characteristics of the solids.

Primary treatment Sedimentation

In the primary sedimentation stage, sewage flows through large tanks, commonly called “primary clarifiers” or “primary sedimentation tanks”. The tanks are large enough that sludge can settle and floating material such as grease and oils can rise to the surface and be skimmed off. The main purpose of the primary sedimentation stage is to produce both a generally homogeneous liquid capable of being treated biologically and a sludge that can be separately treated or processed. Primary settling tanks are usually equipped with mechanically driven scrapers that continually drive the collected sludge towards a hopper in the base of the tank from where it can be pumped to further sludge treatment stages.

Secondary treatment

Secondary treatment is designed to substantially degrade the biological content of the sewage such as are derived from human waste, food waste, soaps and detergent. The majority of municipal plants treat the settled sewage liquor using aerobic biological processes. For this to be effective, the biota require both oxygen and a substrate on which to live. There are a number of ways in which this is done. In all these methods, the bacteria and protozoa consume biodegradable soluble organic contaminants (e.g. sugars, fats, organic short-chain carbon molecules, etc.) and bind much of the less soluble fractions into floc. Secondary treatment system commonly employs an Aeration Tank wherein microorganism culture completely degrades organic as well as inorganic impurities in the presence of either Surface Aerators or Diffused Aeration system.Conventional sewage treatment plant 1

Secondary sedimentation

The final step in the secondary treatment stage is to settle out the biological floc or filter material and produce sewage water containing very low levels of organic material and suspended matter.

Tertiary treatment

The purpose of tertiary treatment is to provide  a final treatment stage to raise the effluent quality before it is discharged to the receiving environment (sea, river, lake, ground, etc.). More than one tertiary treatment process may be used at any treatment plant. If disinfection is practiced , it is always the final process. It is also called “effluent polishing”.

Prefabricated Sewage Treatment Plant

Posted on Updated on


Prefabricated Sewage Treatment Plant

Prefabricated sewage treatment plant or domestic wastewater treatment is the process of removing contaminants from wastewater and household sewage. It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce a waste stream (or treated effluent) and a solid waste or sludge suitable for discharge or reuse back into the environment.

prefabricated sewage treatment plant

Normally Prefabricated sewage treatment plant  requires large area for the proper installation. Conventionally STP has been installed into the bigger land. But nowadays industries and institution are installing Sewage Treatment Plant for the benefit of the environment. Land is the important part of any of the industries and institution i.e. hospital, hotels, schools etc. and they are not able to provide enough space for the conventional sewage treatment plant.

Shubham INC has developed innovation and revolutionary underground stp and Prefabricated sewage treatment plant  (sewage treatment plant) which consume very small area of the land and provide excellent output quality of treated water. underground stp and Package Sewage Treatment Plant mainly consist of Primary clarifier and settler, Aeration tank with bio media, tube setter, disinfection system, Tertiary Treatment, Ultra filtration, UV system and Ozonator.

Treatment scheme are vary upon application to usage basis. Usually institutions want to recycle sewage treated water for flushing and cooling tower application so they need very efficient treatment of sewage. Shubham INC. make underground stp and prefabricated sewage treatment plant type STP provides superior quality of treated sewage which can be recycled anywhere into different applications.
