Field Kit Chitosan Residual Test Kit (CRTK) is used for the detection of chitosan acetate and chitosan lactate in the treated effluent water. Since concentrated chitosan can exhibit aquatic toxicity on rainbow trout in clean laboratory water, it is important to know if there is any chitosan in the storm water after treatment and filtration. This test kit was recently improved to allow for quicker and easier presence/absence detection of chitosan. The chitosan acetate kit tests for concentrations greater than or equal to 0.2 ppm and the chitosan lactate tests for concentrations greater than or equal to 1.0 ppm. Each CRTK comes with 100 filters.
Field Kit BHR-P50 Residual Test Kit (CRTK) used to determine the presence of free residual aluminum in treated water. The method is for use as a field test to determine if the residual aluminum concentration in post-treatment water is above or below 0.3 mg/L. Results that indicate residues that exceed 0.3 mg/L signal that further inspection and maintenance is needed in the storm water clarification system. This test kit has all the materials needed for the detection of aluminum in water. The range and sensitivity for this test kit is 0 – 0.5 ppm AL3+ in distinct concentrations of 0, 0.1, 0.15, 0.2, 0.25 0.3, 0.4, 0.5 ppmAL3+.
