What is this service?
The waste water testing services generally involve analysis of sample on its toxicity level. The waste water coming from the industries needs to be treated before being discharged in to water bodies. The type of treatment depends upon the type and level of contaminants present in the waste water. Following are parameters on which waste water is tested before deciding upon the type of treatment:
Why it is required?
It is mandatory to treat the wastewater before discharging it into any kind of water body. The method of treating the water depends upon its toxicity level and type of contaminants dissolved in it. For all these reasons, industrial clients perform testing on wastewater.
