Test Water: TDS: 250-300 ppm, pH: 7.2 to 7.6, Turbidity: <1 NTU

Various chemical salts were used to adjust the required input water contaminant concentration. A single cartridge was fitted in the filter, and 50L of water was filtered during testing. The filtered water and input water were analyzed using IS/APHA/USEPA methods as applicable.

Test Conditions

Input Water Characteristics:
- TDS: 250–300 ppm
- pH: 7.2–7.6
- Turbidity: <1 NTU
Various chemical salts were added to achieve the required contaminant concentrations in the input water.
Water head in the top container was consistently maintained throughout the test.
Sampling was conducted after filtering 50 liters of water.

Observations and Inference

The tested gravity filter equipped with HMR cartridges demonstrated excellent performance, effectively reducing a range of chemical contaminants, including regulated metals, pesticides, and volatile organic compounds (VOCs). The reduction levels achieved were in compliance with both national and international standards, ranging from 74% to 99%.

Methodology

Preparation:
- HMR cartridges were pre-wetted by soaking in reverse osmosis (RO) water for 1 hour.
- A single cartridge was installed in the top container of the gravity filter.
Test Procedure:
- Contaminants such as metals, pesticides, chloroform (as a surrogate for VOCs), and inorganics were added to the test water.
- The spiked water was introduced into the top container of the gravity filter.
- A filtration volume of 50 liters was maintained for sampling.
Operational Conditions:
- The water head in the top container was consistently maintained during filtration.
- Filtration flow rate ranged from 120 to 220 mL/min.
Analysis:
- Both the filtered water and input water were analyzed to evaluate the reduction of contaminants.
