Mixing Products for Water Pollution Analysis

Wednesday September 26 2018

Water pollution analysis is mandated by several regulatory bodies worldwide. In the US, the Environmental Protection Agency (EPA) is the leading authority on tolerable levels of pollution in distinct water bodies. This is regulated using the basis of the Clean Water Act, which has enabled the EPA to establish a range of pollution control programs for wastewater discharges in numerous industries. These tests are used to quantify chemical and biological contaminants in liquid media such as wastewater, ground or surface water, sediment, and biosolids such as sewage.

Mixing products are routinely used for water pollution analysis to encourage reactions between liquid analytes and chemical or biochemical reagents or to separate homogenous matrices and analyze their liquid-phase constituents separately. The latter process requires mixing products equipped with a separator outlet to partition liquid phases based on their density. These distinct concentrates can then be analyzed in isolation.

There are many EPA-approved water pollution analysis techniques for assessing the pollutive content of a liquid effluent. To meet the robust mixing requirements for water pollution analysis of various analytes and in accordance with pre-defined methods, laboratory mixing products must provide versatile and adjustable experiment parameters.

3D Floor Shaker: Versatility in Contaminant Analysis

Glas-Col’s 3D Floor Shaker is an advanced mixing product designed to simulate the conditions of a flask being shaken by hand, enabling a full range of mixing action with complete elimination of the task’s labor intensity. Up to eight 2l funnels can be shaken simultaneously with a three-dimensional range of motion and speed capabilities from 10 – 170 RPM. Work that would take several analysts hours to complete can now be fully automated and assessed with a speed display resolution of 1 RPM and an incremental speed setting of 10 RPM.

This mixing product is ideal for water pollution analysis via several distinct EPA methods. Holders can be easily clipped in-place with separatory funnels attached and rotated 180 degrees alternately to enable extraction of immiscible constituents. The same principle can be used to introduce chemical or biochemical reagents to the solution during the mixing process.

Our 3D Floor Shaker mixing products can be adapted to accommodate a range of flasks and mixing vessels. We also supply a range of additional mixing accessories to facilitate agitation, mixture, or extraction of more demanding wastewater samples.

The 3D Floor Shaker is suitable for a range of EPA methods, including:

  • Method 1664 for hexane extractable materials such as oil and grease;
  • Method 418.1 for total petroleum hydrocarbons (TPH);
  • Method 507 for assessing nitrogen- and phosphorus-containing pesticides in drinking water;
  • Method 508.1 for detecting the presence of chlorinated pesticides in samples through liquid-solid extraction.

  • This is by no means an exhaustive list of the suitable EPA water pollution analysis methods enabled with our 3D Floor Shaker range of mixing products, but it does provide an overview of the robust and versatile capabilities of the product line.
