3D WASTEWATER TREATMENT PLANT | PT SIER

Summary

The video showcases Pate Seer's modern and eco-friendly approach to wastewater treatment and clean water recycling. Wastewater from industrial estates undergoes a multi-stage process, starting with collection and primary clarification to remove solids, followed by biological treatment in an oxidation ditch, and secondary sedimentation. Sludge is treated for reuse as fertilizer or fuel. The treated effluent is then recycled through aeration, clarification, ultrafiltration, and reverse osmosis to produce high-quality clean water. The final product is rigorously tested in the laboratory before distribution. Pate Seer emphasizes environmental preservation while providing sustainable water solutions for industries and communities.

Takeaways

• 🌊 Wastewater from factories in Paytasir Industrial Estate is first collected in a collector tank for initial processing.
• 🧱 The primary clarifier separates solid particles and reduces BOD and COD levels, with a processing time of 2–3 hours.
• 🦠 The oxidation ditch uses activated sludge bacteria in a biological treatment process to degrade pollutants and organic contaminants over 20–24 hours.
• 🏞️ Secondary sedimentation occurs in a settling tank, where heavier solids settle, and clarified water moves to the effluent tank for storage or reuse.
• ♻️ Sludge from the settling tank is returned to the oxidation ditch to maintain microbial populations necessary for breaking down organic matter.
• 🔥 Collected sludge is processed in a drying bed to reduce moisture content before being disposed of, used as fertilizer, or as alternative fuel.
• 💧 Effluent from the wastewater plant is recycled as raw water, beginning with aeration to enhance purification.
• 🧼 Water then undergoes sedimentation in a clarifier, ultrafiltration with membranes ranging from 0.1–0.001 μm, and further filtering to remove impurities.
• 🔬 Reverse osmosis (RO) is used to remove molecules and ions under pressure, producing pure fresh water, which is tested in a laboratory to ensure quality.
• 🏪 The final clean water is stored in a reservoir tank and distributed to tenants or consumers, emphasizing environmental sustainability and industrial responsibility.

Q & A

What is the main goal of the wastewater treatment process at Pate Seer?

The main goal is to treat wastewater from industrial sources until it becomes clean water, while ensuring environmentally friendly practices.

Where is wastewater from the Paytasir industrial estate initially collected?

Wastewater is first collected in a collector tank before any treatment begins.

What is the function of the primary clarifier in the wastewater treatment process?

The primary clarifier separates solid particles and reduces BOD and COD levels in the wastewater, taking about 2 to 3 hours.

How does the oxidation ditch contribute to wastewater treatment?

The oxidation ditch is a biological process that uses activated sludge (bacteria) to degrade pollutants and organic contaminants over 20 to 24 hours.

What happens in the settling tank after the oxidation ditch?

The settling tank allows secondary sedimentation, where heavier solid particles settle at the bottom, and clarified water moves to the effluent tank.

How is sludge from the settling tank managed?

Sludge is either returned to the oxidation ditch to maintain microorganisms for biodegradation or processed in a sludge drying bed for disposal or reuse as fertilizer or fuel.

What are the main steps in the clean water recycling process at Paytasir?

The steps include aeration, clarification, ultrafiltration, filtration, reverse osmosis, laboratory testing, and storage in a reservoir tank for distribution.

What is the role of the ultrafiltration (UF) unit in water recycling?

The UF unit removes particles ranging from 0.1 to 0.001 micrometers to ensure further purification before reverse osmosis treatment.

How does the reverse osmosis (RO) unit purify water?

The RO unit removes various molecules and ions by applying pressure on a membrane, producing pure fresh water.

How does Pate Seer ensure the quality of the recycled clean water?

Water samples are taken via a faucet from the RO unit and tested in a laboratory to confirm it meets clean water standards before distribution.

What environmental commitment does Pate Seer emphasize in its wastewater and water recycling processes?

Pate Seer is committed to preserving the environment by implementing modern, sustainable, and environmentally friendly treatment processes for industrial wastewater.
