    Sir. jab plant Running condition me hota hai tab secondary clerifier me sludge nahi uthti . Par jab plant band karte hai tab secondary clerifier me sludge uper ati hai. Small flox me. Ply reply

    • @SunnyB11111
      @SunnyB11111 3 роки тому +2

      Because when plant is stopped dissolved oxygen is consumed . But microbes need more oxygen so they extract oxygen from NO3 nitrates and release Nitrogen Gas N2. Which brings small flocs upward. This is called denitrification. If you use OXYSUPER. You can increase the Dissolved Oxygen Level and maintain it for some time . Hope this helps. Regards Team Superweld

    • @ETPKnowledgeJunction
      @ETPKnowledgeJunction  Місяць тому

      Wastewater injection system mein biocide dose karte waqt oxygen dosing isliye stop karte hain kyunki oxygen biocide ke effectiveness ko kam kar sakti hai. High oxygen level biocide ke saath react karke uske potency ko reduce kar deta hai aur unwanted by-products bana sakta hai. Isliye, biocide ko microorganisms ko effectively target karne ke liye oxygen dosing temporarily band kar di jati hai.

    I have one problem my STP low BOD...how to maintain BOD in STP ....

    • @ETPKnowledgeJunction
      @ETPKnowledgeJunction  Рік тому +1

      To maintain Biological Oxygen Demand (BOD) levels in a Sewage Treatment Plant (STP), you can consider the following measures:
      1. **Proper Aeration:**
      - Ensure sufficient aeration in the treatment tanks to promote the growth of aerobic bacteria. These bacteria consume organic pollutants and help reduce BOD.
      2. **Optimize Microbial Population:**
      - Regularly monitor and maintain the microbial population responsible for biodegradation. Adjust the microbial inoculum if needed to enhance treatment efficiency.
      3. **Controlled Loading Rates:**
      - Avoid overloading the STP with more wastewater than it can effectively treat. Maintain a balance between the incoming wastewater flow and the treatment capacity of the plant.
      4. **Nutrient Management:**
      - Provide essential nutrients like nitrogen and phosphorus to support the growth of microorganisms. Adequate nutrient levels are crucial for the biological treatment process.
      5. **Temperature Control:**
      - Maintain suitable temperatures for microbial activity. Warmer temperatures generally enhance the biological processes, but extreme conditions can negatively impact the treatment.
      6. **pH Control:**
      - Regularly monitor and control the pH levels. Microbial activity is often sensitive to pH, and maintaining it within the optimal range enhances treatment efficiency.
      7. **Regular Monitoring and Maintenance:**
      - Implement a comprehensive monitoring program to assess BOD levels and adjust treatment processes accordingly. Regular maintenance of equipment and infrastructure is essential for consistent performance.
      8. **Sludge Management:**
      - Properly manage and remove excess sludge from the treatment system. Accumulated sludge can interfere with the treatment process and affect BOD removal.
      9. **Use of Advanced Technologies:**
      - Consider incorporating advanced treatment technologies such as sequencing batch reactors (SBR) or membrane bioreactors (MBR) to improve BOD removal efficiency.
      10. **Staff Training:**
      - Ensure that plant operators are well-trained to monitor and respond to changes in the treatment process promptly.
      By implementing these measures, you can optimize the performance of a Sewage Treatment Plant and effectively control BOD levels in the treated effluent. Regular testing and adjustments based on monitoring results are key to successful BOD management.

    Aeration me ph barne se kayse roke

    • @ETPKnowledgeJunction
      @ETPKnowledgeJunction  8 місяців тому

      Controlling pH in an aeration tank is essential for maintaining optimal conditions for microbial activity and wastewater treatment. Here are some general strategies to control pH in an aeration tank:
      1. **Buffering Agents**: Add buffering agents such as sodium bicarbonate (baking soda) or sodium carbonate to the tank. These compounds help stabilize pH by resisting changes when acids or bases are added.
      2. **Alkalinity Adjustment**: Monitor alkalinity levels in the tank and adjust as needed. Alkalinity acts as a buffer against pH changes. If pH is too low (acidic), add alkaline substances such as lime (calcium hydroxide) to raise pH. If pH is too high (basic), add acid (such as sulfuric acid) to lower pH.
      3. **Aeration Control**: Adjust the rate of aeration in the tank. Increasing aeration can help raise pH by promoting the release of carbon dioxide, which can lower pH through carbonic acid formation. Decreasing aeration can help lower pH by reducing carbon dioxide stripping.
      4. **Controlled Addition of Acids or Bases**: Add acids or bases directly to the tank to adjust pH. This should be done carefully and gradually to avoid sudden pH swings that can harm microbial activity.
      5. **Microbial Monitoring**: Monitor the microbial activity in the tank, as microbial processes can influence pH. Adjust feeding rates or organic loading to maintain a balance between acid-forming and alkali-forming reactions.
      6. **Regular Monitoring and Adjustment**: Continuously monitor pH levels in the tank and adjust pH control strategies accordingly. Regular testing helps to identify pH fluctuations early and prevent them from reaching problematic levels.

      Activated process mein dissolved oxygen ka mahatva uske roop mein hai ki yeh ek mukhya karan hai aerobic microorganisms ke jeevit rehne aur kriyashaheel hone ke liye. Yeh microorganisms organic padarthon ko tudwane ke liye zimmedar hote hain. Uchit star par dissolved oxygen ka hona in microorganisms ke sanchit vridhi aur metabolism ko sudharata hai, jisse wastewater mein maujood organic pollutants ko prabhavi roop se todna sambhav hota hai. Iske alawa, dissolved oxygen ka hona avashyak hai activated sludge system mein redox potential ko banaye rakhne ke liye, jo nitrification aur denitrification jaise mahatvapurn urvarak nikalne ke prakriyaon ke prabhav ko niyantrit karta hai. Samanya roop se, uchit star par dissolved oxygen ka banaye rakhna avashyak hai activated sludge systems mein prabhavi aur vyavsayik sewage treatment ke liye.

    • @ETPKnowledgeJunction
      @ETPKnowledgeJunction  Рік тому

      Aeration tank mein kam dissolved oxygen ke peeche kai reasons ho sakte hain. Yahan unka vivaran hai:
      1. **Adhik Organic Load:**
      - **Reason:** Influential mein adhik matra mein kachre ke karan microbial gatividhi badh jaati hai, jo adhik oxygen ka upayog karti hai.
      - **Explanation:** Microorganisms kachre ko metabolize karte hain, jisme unhe saans lene ke liye oxygen ki zarurat hoti hai. Agar kachre ka dabav tank ke capacity ko paar kar jaata hai, to oxygen kam ho jaata hai.
      2. **Adequate Aeration Na Hona:**
      - **Reason:** Aeration systems ka upayukat ya asamay aadarsh hone par.
      - **Explanation:** Aeration, sufficient oxygen levels banaye rakhne ke liye avashyak hai. Agar aeration system ka size chhota ho, sahi taur par design nahi kiya gaya ho, ya kharab ho, to ye sufficient oxygen supply nahi kar sakta.
      3. **Tapman Ka Prabhav:**
      - **Reason:** Adhik jal tapman.
      - **Explanation:** Garam pani mein kam dissolved oxygen hota hai. Uchch tapman dissolved oxygen ko ghatane mein madad karta hai, jisse aeration tank mein prashikshit sthiti bana rahti hai.
      4. **Microbial Virodh:**
      - **Reason:** Microbial samuday mein vilinata.
      - **Explanation:** Agar microbial samuday mein vilinata ho, jisme oxygen khapat karne wale bacteria oxygen utpadit karne wale algae se adhik hote hain, to net oxygen utpadan ghat jaata hai.
      5. **Jeharile Padarth:**
      - **Reason:** Prabhavit karne wale jeharile padarth.
      - **Explanation:** Jeharile padarth microbial gatividhi ko rok sakte hain, jisse kachre ke matra mein kami ho aur usse anukool prabhavit ho sake.
      6. **Hydraulic Asamanta:**
      - **Reason:** Hydraulic asamanta ya short-circuiting.
      - **Explanation:** Asamay jal pravah ke karan ya vyavasthit roop se na hone par, aeration tank ke andar ke kshetron mein sufficient oxygen nahi pahunch sakta.
      7. **Poshak Tatvon Ki Kami:**
      - **Reason:** Microbial vridhi ke liye upayukt poshak tatvon ki kami.
      - **Explanation:** Microorganisms ko nitrogen aur phosphorus jaise poshak tatvon ki avashyakta hoti hai. Agar ye kami ho, to microbial gatividhi kam ho sakti hai, jo ki oxygen khapat ko prabhavit karega.
      Kam dissolved oxygen ka samna karne ke liye aeration systems ko optimize karna, organic matra ko niyantrit karna, sahi mishran ka dhyan rakhna, aur hydraulic ya microbial asamantaon ka samadhan karna jaroori hai. Aeration tank mein anukool dissolved oxygen sthiti ko banaye rakhne ke liye niyamit monitoring aur treatment processes ko sahi taur par adjust karna mahatvapurna hai.

    • @ETPKnowledgeJunction
      @ETPKnowledgeJunction  Рік тому

      Sewage or industrial effluent ka treatment karne ke liye, SST (Secondary Settling Tank) ya secondary clarifier ka istemal hota hai. Yeh tank effluent me rehne wale suspended solids ko settle hone me madad karta hai. Iska istemal kaise karna hai, uske liye kuch kadam hote hain:
      1. **Effluent Inlet:**
      - Effluent ko SST me saaf aur slow taur par inlet ke through dalna chahiye. Isse tank ke andar evenly distribute hoga.
      2. **Settling Process:**
      - Pani ko SST me thoda samay ke liye rakhna chahiye taki suspended solids settle ho sake. Is process ke doran gravity ke effects ka bhi istemal hota hai.
      3. **Sludge Collection:**
      - Settling ke baad, bottom par settle hue solids ko collect karna important hai. Is sludge ko regularly remove karna chahiye taki tank ka efficiency maintain rahe.
      4. **Effluent Outlet:**
      - Clear water ko tank ke upper part se outlet ke through bahar nikalna chahiye. Isse ensure hota hai ki saaf pani behtar taur par further treatment ke liye jata hai.
      Yadi aap kisi specific scenario ya facility ke liye guidance chahte hain, toh detailed design aur operation guidelines ki zarurat hoti hai.
