Advanced inlet screening and grit removal technologies that claim to set new performance benchmarks for municipal and industrial wastewater treatment plants are being introduced to Australasia by CST Wastewater Solutions.
The technologies include the latest Smith & Loveless PISTA 360 wastewater grit removal chamber, which extracts 95 per cent of grit as small as 100 microns.
“The established standard for grit removal has been 95 per cent removal at 250 microns, so achieving the same removal efficiency at 150 microns (140 mesh) sets an entirely new benchmark,” said Michael Bambridge, Managing Director of CST Wastewater Solutions.
In addition to the PISTA chamber, which uses a patented V-Force Baffle to increase the effectiveness of the grit removal, CST Wastewater Solutions’ latest technologies include inlet screening, new vertical screens, lateral membrane pre-screens and clarifiers.
“The versatility and efficiency of our clarifier product has been demonstrated in a number of applications undertaken recently in partnership with Smith and Loveless, including an installation on a remote island, where two 11.m diameter clarifier mechanisms were provided for the upgrade of a sewage plant, says Bambridge.
Due to its remote location, the clarifiers were supplied in kitset form, including the steel tank, to minimise on-site work and optimise installation.
The grit removal and pre-treatment technologies are complemented by the pre-engineered Smith & Loveless TITAN MBR (membrane bioreactor) wastewater system for municipal and industrial applications.
The TITAN MBR system marries the wastewater treatment engineering expertise of S&L with existing submerged membrane technology.
Plants come in standard and custom designs, and result in smaller footprints than conventional systems. Integral zones can be added to meet particular effluent goals, including nutrient removal, disinfection, and post-aeration.
