Sources and Types of Wastewater in High-Rise Buildings

Wastewater in high-rise buildings can be categorized into three main types:

1. Domestic Wastewater
   Originating from bathrooms, sinks, and kitchens, this wastewater typically contains high levels of pollutants (high BOD/COD), organic matter, fats, and microorganisms.
2. Cooling Tower Blowdown Wastewater
   Generated from air conditioning and cooling systems, it often contains chemical residues such as chlorine, phosphate, and anti-scaling agents.
3. Cleaning Wastewater
   Resulting from cleaning activities like floor washing, laundry, and equipment sanitation, this water often contains cleaning agents, oil, and suspended solids.

Common Issues in Wastewater Treatment Systems

• Clogged Pipes and Grease Traps
  Caused by the buildup of fats, oils, and organic matter, along with solids like hair, food scraps, and plastic.
• Unpleasant Odors
  Typically due to the accumulation of hydrogen sulfide (H₂S) and ammonia (NH₃) gases in the system.
• System Overload and Inefficiency
  When the volume of wastewater exceeds the system’s capacity or the BOD/COD levels are too high, treatment becomes ineffective. Additionally, microbial activity may deteriorate over time.

Recommended Solutions

• Enhance treatment efficiency by adding high-quality microbial cultures.
• Adjust the wastewater flow rate to align with system capacity.
• Maintain proper Dissolved Oxygen (DO) levels.
• Regularly remove sludge from treatment tanks.
• Inspect and maintain mechanical systems like stirrers and recycle pumps.

Wastewater System Maintenance Tips

• Regularly monitor water quality parameters such as pH, BOD, COD, and Suspended Solids (SS).
• Clean grease traps and drainage pipes every 3–6 months.
• Clean aerators and treatment tanks frequently.

Using KEEEN Products for Odor and Wastewater Management

KEEEN’s Bio Organictech innovation stems from intensive research and features a proprietary selection of 8 specialized microbial strains (Augmented Microbes) capable of breaking down stubborn grease and complex organic waste. These strains work by breaking fats into fine particles, decomposing them into water, and performing efficiently under high temperatures without the need for nutrient feeding—unlike conventional systems.

Recommended KEEEN Products:

🔹 KEEEN Wastewater Treatment
A bio-microbial solution that degrades organic matter and reduces BOD, COD, and SS levels.

🔹 KEEEN Max Blend
A concentrated microbial booster designed to enhance system performance during startup or high-load periods.

🔹 KEEEN Odor Eliminator
Eliminates unpleasant smells in treatment tanks and drainage pipes.

🔹 KEEEN F.O.G. Digester
Effectively removes grease from general surfaces and reduces the burden on wastewater systems by replacing harsh chemicals.

By incorporating KEEEN’s solutions, high-rise buildings can ensure optimal wastewater treatment performance, minimize environmental impact, and stay compliant with urban environmental regulations.

Managing wastewater in high-rise buildings requires knowledge of both engineering and environmental practices. Common issues such as clogging, odor, and reduced treatment efficiency can be effectively resolved through proper maintenance and the application of advanced biotechnology. KEEEN’s Bio Organictech microbial solutions offer a sustainable, effective path to reducing the ecological footprint of growing urban infrastructures.
