The EPA’s Clean Water Act prohibits the discharge of toxic pollutants in amounts that can adversely affect freshwater and marine organisms. Whole Effluent Toxicity (WET) tests are used to measure wastewater's effects on specific test organisms' ability to survive, grow and reproduce.
Time Consuming and Expensive
These acute toxicity tests generally involve exposure of living test organisms – including plants, vertebrates and invertebrates – to various effluent concentrations from a facility’s effluent stream, along with a control water sample. WET tests take from 24 to 96 hours to complete, and will cost you not just time, but often significant expense as well, requiring an expensive onsite lab setup or necessitating that the facility send samples to an outside testing lab.
PAM vs All-Natural Treatments
One of the key contaminants that may be found in treated wastewater effluent is residual chemistry from the synthetic polymer flocculants being used to remove heavy metals, organic matter like fats, oils and grease, and other solids and contaminants. Wastewater treatment facilities that utilize all-natural, chitosan-based flocculants like Dober’s HaloKlear, however, are realizing multiple benefits – including ease of residual testing.
A Better Way to Test
Dober offers a Residual Test Kit that enables your facility to prove, onsite, that no residual HaloKlear chemistry is being released back into the environment. The Residual Test Kit lets you view results in 10 minutes or less – and costs only a few dollars per test, significantly less expensive than an offsite lab test.
Validate Results on the Spot!
The HaloKlear Residual Test Kit uses proven test methods for detecting the presence of residual chitosan before it leaves your facility. No need to spend thousands on WET tests or lose production time waiting for results. The new, patent-pending HaloKlear Residual Test Kit is more consistent and reliable than other test kits, with results that are 25% more accurate than other kits.
