The relationship between TDS (total dissolved solids) and conductivity depends on the water chemistry. For example, 1,000 mg/L of NaCl will give a different conductivity than 1,000 mg/L of MgSO4. The very rough rule of thumb is TDS, mg/L × 1.6 = Conductivity (µS/cm). The factor of 1.6 used in the equation has a typical range of 1.4 to 1.8, though wider variations are certainly possible.

When possible, the best correlation is developed from the analysis of specific water or waste stream for both TDS and conductivity from which a specific correlation factor is produced. Then, if the water chemistry remains fairly constant, conductivity can serve as a good indication of TDS. If the water chemistry changes significantly, the rule of thumb will not work.

what-is-total-suspended-solids-tss-netsol-water-solutions-9650608473.png

TSS stands for Total Suspended Solids. TSS is that suspended particles (Dry-weight) in water that is not dissolved, can be trapped by a filter by using a filtration system in a sample of water. It is also a major water quality parameter used to access the specimen by any type of water or waterbody, for example, ocean water or wastewater after the treatment in the wastewater treatment plant.

Total Dissolved solid acquired through separate analysis to determine water quality. In previous, TSS is also known as a non-Filterable residue (NFR), changed due to a nonproper understanding of other scientific disciplines.

How Does TSS Affect the Water Quality?

When you are talking about water quality, due to the high level of total suspended solids the temperature of the water is dramatically increased and the total dissolved oxygen level decreases. This all happens just because the suspended particles absorb extra heat from solar radiation than the normal water molecules do.

How TSS Is Measure in water or wastewater treatment

The most accurate and common method of measuring the TSS is by weight. A water sample is filtered, dried, and weighed. This method is most accurate in all other techniques of measuring Total Suspended Solids. Sometimes it is also difficult and takes more time for perfect results.

What is the Total Suspended Solids calculation Formula (mg/L)?

TSS in water or wastewater treatment plant calculated in milligram per litter as per the following given equation:

(Dry weight of residue and filter – the dry weight of filter alone, in grams) / ml of samples * 10,00,000

How to lower your Total suspended solids in Wastewater Treatment?

The most important measure in the Wastewater treatment plant is TSS. Total suspended solids level must have adhered to state environmental regulation. Because high TSS levels can harm wildlife and dangerous to human health. Your wastewater treatment equipment also can be damaged by elevated TSS.  By following some of the given effective ways to keep your TSS under Control.

  • Focuses on removing first TSS from wastewater
  • Used a properly sized EQ Tank (Equalizer Tank). This will help to maintain the flow and loading rate.
  • Control over the pH of the wastewater. It is the basic and most important to manage the pH Level. To know more read: What is ph in wastewater?
  • Use modern stainless steel or plastic make plate pack DAF.
  • Use of the regenerative air dissolution turbine pump uses minimal electricity to dissolve air into water. This may lead to producing 20-30 micron air bubbles.
  • Use high rated modern DAF which cleans by you to avoid facing clogging, solids separation problems, higher TSS, and high chemical feed rate.
  • Use performance-tested liquid chemistry which allows for full automation to lower the cost, and eliminates the wetting issue.
  • Locate properly chemical injection points and always test them.

By reading the above point you are able to know that how to control TSS, which is a crucial part of your wastewater treatment plant.

whats-is-the-full-form-of-wwtp-Netsol-Water-Solutions-9650608473.jpg

The treating process of wastewater or sewage takes into a place known as WWTP, which is stands for Waste Water Treatment Plant. It is also referred to as Water Resource Recovery Facility(WRRF) but if you are talking in terms of domestic wastewater it is known as Sewage Treatment Plant(STP).

Wastewater Treatment is a process of use for removing the contaminants from wastewater or sewage water and automatically works using a different process to convert it wastewater into an effluent which is acceptable for the water cycle.

Steps involved in wastewater treatment plant
Steps involved in the wastewater treatment plant

Wastewater treatment plant process

Any WWTP follows 8 major steps during the wastewater treatment process. WWTP major process is as follows-

  1. Screening and Pumpinghttp://www.sewagetreatmentplants.in/what-is-the-full-form-of-wwtp-s
  2. Grit Removal
  3. Primary Settling
  4. Aeration / Activated Sludge
  5. Secondary Settling
  6. Filtration
  7. Disinfection
  8. Oxygen Uptake
  9. Sludge Treatment

WWTP steps in Detail-

Now when you aware of the steps used in treating wastewater via STP or WRRF system. We discuss each step in detail-

1- Screening and Pumping –

Wastewater first comes through screening equipment where the material like – woods piece, plastic, rags, and other non-fluid objects are removed from it. After removing Greece and other objects wastewater is pumped to the Next Step: Grit Removal

2- Grit Removal –

In Second Step, the heavy and fine material eg- sand and gravel is removed from the wastewater.

3- Primary Settling –

During this step of treatment, a large circular tank knows as clarifiers used to do some work like step 2 but in a slow process. All the material is settled in the bottom of the tank and called primary sludge. This step also includes phosphorus removal by adding chemicals into it.

4- Aeration / Activated Sludge –

This water treatment includes most of the treatment. The biological Degradation process indulges to consume pollutants by microorganisms and transformed into nitrogen, water, and cell tissue. This biological activity is happening the same as the bottom of rivers and lakes, but this process is fast than the natural way which takes years to accomplish.

5- Secondary Settling –

Secondary clarifiers allowed treated wastewater to separate from biological from aeration tank, yielding effluent is now 90% treated. The activated sludge is pumped from the bottom of clarifiers continuously and send it again to step 4.

6- Filtration –

By using micron polyester media effluent is polished. Disc Filtered material from the surface is periodically back-washed and returned to the head of the plant for treatment.

7- Disinfection –

This step assure that there is no harmful bacteria or viruses are present in treated water. Ultra disinfection is used to kills remaining bacteria to level at the discharge permit.

8- Oxygen Uptake –

In this step of WWTP, Now high quality and stabilized water are available in this process. if it is necessary to aerate to dissolved oxygen to the permitted level. The water before discharge to the river must meet the requirement set by DNR, pollutant removal is maintained at or greater than 98%.

9- Sludge Treatment –

The primary sludge is which is pumped to step three of clarifiers from the bottom of the tank. The treatment of the sludge process involves different steps. And produce minimum and organic waste.

The basic function of wastewater treatment is to speed up the natural processes by which water is purified. There are two basic stages in the treatment of wastes, primary and secondary, which are outlined here. In the primary stage, solids are allowed to settle and removed from wastewater. The secondary stage uses biological processes to further purify wastewater. Sometimes, these stages are combined into one operation.

What is a wastewater treatment system?

 

A wastewater treatment plant is a Combination of systems made up of several individual technologies that used for your specific wastewater treatment needs.

Sewage Treatment is rarely a static process, and a wastewater treatment system that is engineered to accommodate fluctuations in treatment needs will go a long way in avoiding costly replacements/upgrades down the line.

An efficient and well-designed wastewater treatment system should be able to handle:

  • process variations in contamination and flow
  • variations in water chemistry needs and required chemical volumes adjustments
  • possible changes in water effluent requirements

For a detailed information stage and flow diagram of sewage treatment plant/wastewater treatment plant, you can watch the complete video.

activated-sludge-process-of-stp-plant-netsolwater-solutions.jpg

Biological treatment processes are a crucial component in many wastewater treatment systems. They’re one of the foremost efficient and effective ways of reducing organic material within the wastewater. There are quite a few of them that are researched and used over several decades. However, one among the foremost widely used conventional biological treatment processes is that the activated sludge process (ASP). Many sewage treatment plants use ASP within their secondary treatment steps thanks to the human and animal organic matter in the inlet waters of wastewater treatment plants.

The term “activated sludge” comes from the very fact that the sludge contains live bacteria and protozoa that actively digest and break down sewage. it’s different from the sludge solids removed following a settling process therein way, with the addition of being odorless.

The process itself involves pumping the effluent from the first treatment clarification step into an outsized tank that contains the activated sludge. The mixture is subjected to aeration, either from submerged or surface aerators. This provides oxygen to the effluent that the bacteria can then use to interrupt down the organic waste. After a sufficient amount of hydraulic retention time, the resulting slurry is pumped into a clarification system or tank to settle out the remaining solids. The treated water is pumped far away from the highest to any subsequent polishing filtration and disinfection while the sludge at rock bottom is re-circulated back to the ASP tank to reseed the leftover activated sludge.

We have included the most potential disadvantages of the activated sludge process to be discussed below.

Hydraulic Retention Time

 

Perhaps the foremost important aspect of any wastewater treatment process is time. Any treatment solution needs time to run its course and certain treatments take longer than others. ASP is one of those solutions. Thanks to the ratio of sewage to sludge and the way the method occurs, the hydraulic retention time of ASP can take most of each day (12-24 hrs.) or up to many days (3-5) to realize appropriate levels of treatment results.

Sludge Retention Time / Recycling

Time also applies to the medium of the reaction. In this case, the medium is that the activated sludge. With regards to the sludge itself, an ASP is an open system and there’s a special mass rate entering the system than there’s exiting the system.

Overtime (without a recirculation system) all of the activated sludge within the tank would get pumped out. the thought is to maximize the time the sludge spends within the system. this point is to make sure there’s enough biomass to interrupt down the incoming organic matter; hence the necessity for recirculation.

Therefore, as most suspended growth biological processes or fixed film processes including MBBR have higher sludge retention times, ASP tends to possess lower sludge retention times.

Size

Due to both of the points stated above, reactor tanks for the activated sludge process (ASP) tend to be quite large so as to treat larger volumes of effluent. this needs large areas of land needed for his or her operation.

Changes in Volume or Character of Sewage

ASP can treat large quantities of varied organic materials, but the reaction depends on variables that make it quite vulnerable to an error in conditions outside of these it had been designed for.

In particular, changes in sewage volume and sewage characteristics may result in decreased treatment quality or treatment upsets. If a treatment plant decided it wanted to extend its treatment volume or began treating wastewater from a replacement and different source, the ASP reactors would typically be got to be completely redesigned accordingly.

Sludge Disposal

As are often expected from handling a treatment process that uses sludge to treat sewage, there are considerable volumes of sludge that require to be disposed of after this process. Larger sludge volumes mean higher associated disposal costs.

Operation / Supervision

Biology may be a complex subject; therefore, it stands to reason that a biological water treatment process would be complex in certain aspects. On a broad scale, the general process seems simple enough. However, the planning and operation of an Activated sludge reactor typically require experts in biological systems design to watch it. A system like this needs a touch more skilled supervision than simply watching out for mechanical failures and monitoring pH. There must be highly skilled operators and supervisors which will check for the viability and efficiency of the bacteria and protozoa within the sludge to stop system upsets.

Issues with Sludge Settling

Some of the most important issues with the activated sludge process reveal themselves in how everything settles call at the secondary clarification process. Sometimes, the solids don’t compact alright at rock bottom and therefore the sludge has high water content.

Sometimes, the supernatant (floating material) has higher turbidity than you would like which may affect the top effluent water quality. Other issues may result in decreased concentrations of return activated sludge.
