The purpose of laboratory testing of the products of the smelter is to determine which components of the waste have a detrimental effect on the environment. The questions that need to be raised are:

(1) What is the product of chemical reactions and biochemical reactions in waste?

(2) What effect does waste discharge have on water quality?

(3) How is the toxicity of waste and its decomposition products to animals and plants in the environment receiving waste?

After performing a variety of testing procedures, waste can be classified according to the above criteria. These tests include an outer row of acid mineral water is detected, and detecting the metal dissolution bioassay.

SME heavy duty cantilever metal sump pumps are abrasive resistant pumps for extended wear life and reliability in sumps or pits.

They are designed for applications requiring greater reliability and durability than conventional vertical process pumps can offer.
The heavy duty cantilever design makes the SME Sump Pump ideally suited for heavy continuous handling of corrosive
