The need for effective headworks systems – namely screening and grit removal – is more critical than ever for wastewater treatment facilities, driven by the increasing prevalence of flushable wipes and the necessity to safeguard newer, more advanced treatment methods. For municipalities with small and medium flows, Smith & Loveless offers a game-changing advantage: PISTAWorks.
Combining fine screening technology with a complete advanced grit-removal and dewatering system arranged on a factory-built skid, PISTAWorks delivers the confidence of a timely, on-budget installation. Preassembled and pretested, the stainless steel-constructed headworks system arrives on a skid, ready for easy installation, and shipped to the job site on a single truck.
PISTAWorks comprises state-of-the-art technology. It offers designers and end-users flexibility to incorporate the ideal screening technology for the application, selecting from mechanical bar screens, drum screens or basket screens, and from coarse to fine screening options. Likewise in the grit-removal phase, designers can select from a variety of Smith & Loveless PISTA Grit Chamber and grit washing/dewatering options yet still achieve a minimum of 95% grit removal efficiency for all flow conditions for particles down to 105 microns.
A win-win solution
PISTAWorks provides significant benefits to engineering firms, construction contractors and small to medium municipalities.
Regional engineering firms that serve small communities don’t need to invest time and resources in developing specialized expertise in screening and grit-removal technology and intricate headworks facilities, which may not be part of the firm’s normal project load. Working with PISTAWorks enables firms to broaden their service offerings without overextending their resources, while still providing clients with reliable, state-of-the-art headworks solutions. Consider elements of the system that are already engineered, like safety features, controls and wiring:
Safety features. PISTAWorks comes pre-equipped with essential safety components such as platforms, handrails, ladders and emergency stop mechanisms. These features, thoughtfully integrated into the design, reduce liability concerns and ensure compliance with OSHA regulations.
Integrated intuitive controls. Integrating all components into a single PLC-based control panel streamlines operations by eliminating the need for multiple, separate systems. A user-friendly graphical user interface and multilingual Spanish support minimizes system complexity, simplifies training, and improves the efficiency of troubleshooting.
Factory wiring. Factory wiring and UL certification simplifies installation. Preinstalled conduit and electrical components further ease the process by eliminating the need for contractors to embed conduit in concrete or manage extensive on-site electrical work.
Construction contractors benefit from simplified installation processes. Unlike traditional site-built systems, this preassembled solution comes ready to install, minimizing concrete pouring except the pad. This reduces construction risks, saves time and eliminates costly rework, enabling contractors to complete projects efficiently and confidently.
For municipalities, preengineered headworks systems ensure a state-of-the-art wastewater treatment solution that is dependable and easy to maintain. With proven system design and integrated controls, these systems offer predictable performance and streamlined operations.
A valued feature of PISTAWorks is its manual bar screen bypass, a built-in solution that ensures seamless operation even during routine maintenance or unexpected screen downtime. By switching to the manual bar screen, facilities can avoid shutdowns and maintain system efficiency. Some customers choose redundant screens to ensure continuous operation during maintenance or equipment downtime, eliminating the need for maintaining a manual bar screen.
