Purpose:

Proper maintenance ensures reliable operation, compliance with environmental regulations, and extended equipment lifespan. Key areas:

- Mechanical & Electrical Maintenance

- Process Maintenance

- Preventive & Predictive

- Wastewater Chemical Analysis

Testing is critical to ensure discharge meets DOE/EPA/Local authority standards.

1. Basic Parameters

2. Nutrient

3. Organic Load

4. Heavy Metals & Toxic Substances

Typically, maintenance is done daily (routine checks), weekly (minor servicing), and monthly/quarterly (major servicing & calibration).

Chemical analysis is carried out daily for operational control parameters (pH, DO, TSS) and weekly/monthly for compliance parameters (BOD, COD, heavy metals).
