Lab Test Results for Chlorine Removal in Hot Water Shower Filter with KDF Process Media
Lab Test Results for Bacteria from Sprite Industries
Shower Master (SR-1) 5,000 gallon test results:
LR: 81590 Utilizing 18 oz of KDF® 55D
| Purpose: |
To demonstrate free chlorine removal by a standard Shower Master (SR-1) shower filter over a minimum duration of 5000 gallons. |
| Equipment: |
- Shower master filter with standard shower head (SR-1)
- Two-way Diverter (SA-3)
- Standard shower head (S-1) with 2.5 GPM Restrictor
- Faucet hose/shower arm assembly
- Chem-Tech Pulsafeeder Model 100/020 with 15 gallon tank
- Collecting pan
- 10% sodium hydro chlorite solution
- Thermometer, 32-125° F
- Chlorine test kit/Titratin (Lamotte DT-DR)
|
| Set up: |
The faucet hose/shower arm assembly was constructed so as to attach to the hot and cold faucet at the input and the diverter (SA-3) at the output.
A Shower Master filter with a standard showerhead (SR-1) was attached to the two-way diverter's in-line port and a standard showerhead (S-1) to its angled port. A Chem-Tek pulsafeeder model 100/030 injected 10% hypo chlorite solution via a tee fitting, midway at the faucet hose. A collecting pan with thermometer was placed under showerheads for gathering samples. |
| Procedure: |
- The output water was adjusted to 103 - 105°F
- The chlorine PPM (parts per million) content from the non-filtered water was adjusted to 2.2-2.4 ppm
- The output flow for both Shower Master filter w/standard shower head and the standard showerhead w/no filter was 2.5 gallons
- Samples were drawn form a 2.5 collecting pan for both samplings
- Parts per million of free chlorine was determined by use of Lamotte Chemical Chlorine test kit, Model DT-DR, Direct Reading Titrator
- Initially, 103-105°F temperature water was sampled at the start of the days test run. Within a 30 minute period the hot water heater because exhausted. The water temperature lowered and stabilized at approximately 82-84°F. At the end of each testing period, the system was shut down to allow for a final sampling again at the 103-105°F temperature
|
| Results: |
Due to limitations of the testing apparatus two groups of data appeared.
- Normal showering temperature data at 103-105°F yielded a 96 - 100% removal of chlorine.
- Cooler than normal showering temperature data set at 82-84°F yielded a 83-91% removal of chlorine.
|
| Conclusion: |
The percent of chlorine removal is directly related to temperature. At normal showering temperatures, 103-105°F the Sprite Shower Master removed from 96-100% of the free chlorine. |
