Iron Removal Media Filtration

DMX-065

Independent Laboratory Test Report

Sample Source: North Bore water - Iron Manganese Sand Media Trial (13th May 03)

Sample Use: Water Filtration

Test Method: Samples submitted by client are analysed on as received basis.

Analysis performed in accordance with MPL WILAB 5.0, 6.0 and 8.0

Analysis performed in accordance to NATA certification

Certificate of Analysis:

Analysis

Raw Water

Treated Water

Comments

Drinking Water Guidelines (1996)

Total Iron (mg/L)

11.8

0.005

Iron stains above 0.1 mg/L

0.3 ppm is regarded as acceptable.

High concentrations cause staining on brickwork, blockages in pipes & drip feeders, corrosion problems in bores.It also reduces the efficiency in hot water systems & radiators etc

Manganese (mg/L)

0.49

0.001

Manganese will stain above 0.1 mg/L

< 0.1 ppm is regarded as acceptable.

High concentrations cause staining on brickwork, drip feeders, plumbing fixtures, in the laundry, etc

N/S = No Specified Maximum given

+ = indicates sample received outside holding time recommended by AS 5667.1. 1998

The Comprehensive mineral analysis results (including heavy metals) for both water samples are attached.

28 parameters were tested.

Analysis was performed in accordance to NATA certification.

Results were compared to values taken from “Australian Drinking Water Guidelines” published by NHMRC and ARMC 1996 (*refers to updated value September 2001)

All analysed results for the treated filtered water were within “Australian Drinking Water Guidelines” except for pH - which was slightly low.
