Major advances in fine grit removal engineering to be highlight of Ozwater ’13

Advanced Smith & Loveless grit removal technologies strongly relevant to Australian wastewater treatment plants will be presented by CST Wastewater Solutions at the Ozwater ’13 international water conference and exhibition in Perth from May 7-9.
This follows a recent educational initiative by CST Wastewater Solutions and Smith & Loveless to host a series of grit seminars earlier this year focussing on grit removal, testing, pumping and dewatering. Well attended by the Australian professional engineering community, the seminars discussed the latest developments in grit removal system design, technology advancements and performance.
One of the main points discussed by Mr Chuck Miller of Smith & Loveless USA and particularly pertinent to the Australian market was the analysis of grit particle size for coastal regions. According to Mr Miller, as much as 40-80% of the grit contained in typical municipal wastewater is in the 105-200 micron size range, whereas most grit removal systems are only designed for removing grit in the 200-300 micron range.
The S&L PISTA and V-FORCE BAFFLE grit removal systems are designed to remove 95% of all grit particles down to 105 microns, setting a new industry benchmark for grit removal efficiency and performance.
Sampling and testing of grit removal system performance was another subject covered at the seminars. Most grit systems are supplied based on a Performance Specification, which is rarely tested and verified. After conducting over 150 certified field performance tests, S&L has developed a standard methodology for grit sampling.
Managing Director of CST Wastewater Solutions, Mr Michael Bambridge comments that while grit is not the most glamorous of subjects, it is critically important in the design of modern wastewater treatment plants.
CST Wastewater Solutions is an Australian supplier of Smith & Loveless technologies. CST has been providing a broad range of industrial and municipal water and wastewater solutions for 25 years, with projects also completed in Europe, Asia, Africa and America.
