Thanks to Australia’s heavily coastally oriented demographic, sand and fine grit are ever-present problems in municipal and industrial water and wastewater systems. What’s more, between 40 and 80% of the grit found in municipal wastewater is in the 105-200 micron size range, which is a problem because most grit removal systems are only designed to remove grit in the 200-300 micron range.
At the Ozwater 20 exhibition (from 5th to 7th May in Adelaide), local wastewater and screening authority CST Wastewater Solutions will be showcasing the latest advances in fine screening, grit removal and clarifier technologies, including globally proven Smith & Loveless technologies, for which it is Australian distributor.
Smith & Loveless’ latest Pista Vio system removes 95% of grit down to 105 microns, and features full variability of the inlet and outlet channels.
The system features a hydraulic vortex grit chamber design that uses a novel baffle system. This type of grit removal system – one of the first of its kind in the industry – provides the ability to design the inlet and outlet channels at any variable angle up to the full 360° of the chamber. Designers can arrange the system to fit existing sites, or maximise space during construction on new sites.
In addition to grit removal, CST will also be displaying its range of Smith & Loveless clarifier technologies at Ozwater 20, including centre feed clarifiers, peripheral feed clarifiers, and solids contact clarifiers, which can all be custom designed to customer specifications.
One of the latest Smith & Loveless clarifiers is the Clar-I-Vator, which is a high-rate solids contact clarifier for economical and efficient chemical precipitation in municipal and industrial water and wastewater treatment applications.
“The Clar-I-Vator has a number of design and process advantages. It minimises the amount of chemicals needed and provides a stable process operation that is less dependent on incoming flow variations,” says Michael Bambridge, Managing Director of CST Wastewater Solutions.
“It is simpler to operate and requires less ongoing maintenance compared with typical sludge blanket designs. It also produces the highest level of effluent quality due to the deep water clear zone,” he adds.
