Wastewater seminars handle the tough questions on grit removal

Grit that is not properly handled can cause problems in pipes, pumps and other equipment in wastewater treatment plants, as well as incurring maintenance costs in the future. Although the grit chamber is the centre-piece unit and key selection in any grit removal scheme, other important aspects include the selection of grit handling equipment, arranging the grit piping, and selecting components for the second-stage grit washing and dewatering phase.

There are three important reasons to wash and dewater grit: odour reduction, improved grit-removal efficiency and ease of grit disposal. Properly designed systems are streamlined with quality component equipment to not only maximise the entire system efficiency but also minimise field maintenance and problems.

CST Wastewater Solutions, in a partnership with Smith & Loveless, is providing grit seminars in Brisbane, Adelaide and Sydney on 19, 20 and 21 February. The seminars will focus on all the important aspects of grit removal, including:

• Grit removal design recommendations
• Types of grit removal technologies
• Grit handling design
• Grit removal system hydraulics
• Enhancing grit removal performance

The seminars aim to educate engineers and operators on the latest technological developments and procedures for grit removal equipment. For example, the Smith & Loveless PISTA 360 wastewater grit removal chamber is said to extract an unprecedented 95% of grit as small as 105 microns. 

In addition to the PISTA chamber, which uses a V-Force Baffle to increase the effectiveness of the grit removal, CST Wastewater Solutions’ latest technologies include high-performance inlet screening, vertical screens, lateral membrane pre-screens and clarifiers.
