Contaminants to Remove (Including TOC, BOD, COD)

Proper identification of target contaminants allows for effective treatment design. Categories include:

Suspended Solids (SS): Removed through sedimentation or filtration.
Organic Matter: Causes color, odor, and biological activity. Key indicators:
- BOD (Biochemical Oxygen Demand): Oxygen required by microorganisms to break down biodegradable organics in water over 5 days. High BOD = high pollution.
- COD (Chemical Oxygen Demand): Oxygen needed to chemically oxidize all organics (biodegradable and non-biodegradable). Faster test than BOD.
- TOC (Total Organic Carbon): Total carbon from organic substances; useful for real-time monitoring.
Heavy Metals: Must be removed due to toxicity.
Pathogens: Require disinfection.
Oils and Grease: Removed using skimmers or chemical coagulants.

Design Smarter : 6 More Essentials in Water Treatment System Design

Required Water Quality

Ensure safe water quality for every application

Meeting WHO, EPA, and local standards to deliver safe, compliant water quality.

Contaminants to Remove

Identify and eliminate harmful water pollutants

From solids to organics and metals, effective removal ensures clean and safe water.

Technology Selection

Smart solutions for efficient water treatment

From pre-treatment to advanced processes, technology ensures reliable purification.

Raw Water Quality Analysis

Hardness, Conductivity, Turbidity, TOC, BOD, COD, TKN, Heavy Metals

Accurate testing ensures reliable treatment performance and consistent water quality.

Production Capacity / Wastewater Volume

Determining system capacity for water production or daily wastewater generation.

Optimize system sizing to balance efficiency, cost, and long-term sustainability.

Regulatory Compliance and Standards

Ensuring system design and operation meet all relevant laws and quality standards.

Continuous monitoring guarantees safe, efficient, and legally compliant operation.

Designed for efficiency and sustainability, our water and wastewater treatment systems lower energy and operating costs while enhancing reliability and extending system life. We are here to support you every step of the way.
