  • Polychem - Non-Metallic Telescoping Head Shaft

    Polychem - Non-Metallic Telescoping Head Shaft

    The Polychem non-metallic telescoping head shaft was invented and installed as part of the first 100% non-metallic system in 1984. At that time, the industry was just beginning to test plastic as a lighter, corrosion-resistant alternative to steel. Today, Polychem non-metallic head shafts have become the water treatment industry’s gold standard.

  • Polychem - Idler Stub Shafts

    Polychem - Idler Stub Shafts

    Polychem idler stub shafts are the lightweight alternative to traditional full-width steel shafting and cast iron wall bearings. We offer two base diameters and lengths to accommodate sprocket centerlines from 9 to 29 inches off the wall, allowing customized stub shafts to fit various tank sizes, system loadings, and existing structural conditions.

  • Polychem - Sprockets

    Polychem - Sprockets

    Brentwood’s Polychem sprockets are molded from a specially selected, high-strength Nylon material that outwears and outlasts UHMW-PE and polyurethane sprocket alternatives. All sprockets are equipped with standard integral teeth to maintain tooth alignment and are designed for use with Polychem collector chain.

  • Polychem - Collector Head Shaft Sprocket

    Polychem - Collector Head Shaft Sprocket

    The hunting-tooth profile of the NCS-720-S collector sprocket features an odd number of teeth at half the chain pitch, offering twice the life of full-tooth sprockets. The split design allows for use with full-width-span shafting and simplifies installation, while the integrally molded chain-saver rim decreases chain and sprocket wear.

  • Polychem - Solid Idler Collector Sprocket

    Polychem - Solid Idler Collector Sprocket

    Solid idler sprockets slide onto stub shafts for quick and easy installation and are held in place with retainer plates. The integrally molded chain-saver rim decreases chain and sprocket wear.

  • Polychem - Model NH-78 - Bull Gear Driven Sprocket

    Polychem - Model NH-78 - Bull Gear Driven Sprocket

    The NH-78 Bull Gear driven sprocket is standardly furnished with 40 integral teeth and designed for use with NH-78 drive chain. Polychem driven sprockets are one third the weight of bull gears with cast iron hubs, making them much easier to install.

  • Polychem - Flight Scraper

    Polychem - Flight Scraper

    Brentwood offers more flight scraper options than any other chain and flight manufacturer, enabling us to provide sludge collection solutions for any water or wastewater application. In addition to industry standard c-channels, Polychem’s flight offering includes the proprietary Ultra, Ultra Plus, Box, and Bridge flights for heavy loadings and deep sludge blankets. The Ultra Plus and Box flights provide sturdy and reliable options for wide tank...

  • Polychem - Model NCS-720-S - Sludge Collector Chain

    Polychem - Model NCS-720-S - Sludge Collector Chain

    Brentwood's Polychem NCS-720-S Collector Chain is among the strongest 720-series chains on the market. Precision molded from durable, glass-reinforced polyester, this lightweight chain withstands high sludge loadings in corrosive environments. Our collector chain can also be protected with barrel wrap for high grit or highly caustic conditions. By reducing barrel wear, the chain lasts longer and performs better.

  • Polychem - Drive Unit Assembly

    Polychem - Drive Unit Assembly

    Brentwood supplies drive units that are custom configured for each collector based on system requirements and regional and environmental conditions. Each system utilizes a motor and gear reducer and optional components such as overtorque protection to prevent drive system failure, a drive chain tightener to maintain tension, and a chain guard to protect rotating equipment above the deck.

  • Polychem - Model NH-78 - Drive Chain

    Polychem - Model NH-78 - Drive Chain

    Brentwood’s Polychem NH-78 Drive Chain is used to drive flocculators, screw conveyors, chain and flight collectors, and a range of other low-speed applications. Injection molded from glass-reinforced nylon, NH-78 is strong, lightweight, and resistant to corrosion and chemical damage. This non-metallic replacement for heavy metal chains is simple to install and maintain without special tools. Our drive chain can also be protected with barrel wrap...

  • Polychem - Torque Limiter

    Polychem - Torque Limiter

    The Polychem Torque Limiter is an easy-to-reset alternative to traditional shear pin devices. It provides reliable overtorque protection by transmitting torque through balls retained in detents against adjustable spring pressure. When torque exceeds a preset value, the balls leave their seats and roll free to completely disengagem the driving and driven components, preventing costly drive system crashes.

  • Polychem - Scum Removal

    Polychem - Scum Removal

    The removal of scum during clarification is an essential step to decrease organic loadings and scum buildup in subsequent treatment processes. Brentwood’s rotating scum troughs and skimmers efficiently remove all grease, scum, and floating material from the water surface in rectangular clarifiers and settling basins.

  • Polychem - Rotary Scum Skimming Troughs

    Polychem - Rotary Scum Skimming Troughs

    Rotary scum skimming troughs are the most economical method for removing all grease, scum, and other floating materials from the water surface in rectangular clarifiers. Scum troughs can rotate up to 75 degrees both forward and backward to accommodate changes in water level and collect surface material from either side of the trough. Slotted weirs are cut longitudinally along the top of the trough, evenly distributing flow throughout the length of the...

  • Polychem - Rotating Helical Skimmer

    Polychem - Rotating Helical Skimmer

    The rotating helical skimmer assembly is designed to remove all grease, scum, and other floating material from the water surface, including light, slow-moving scum that will not readily float to traditional scum troughs. As the helical skimmer continually revolves 360 degrees, its rubber wiper blades lift the surface scum up a curved steel or concrete beach and deposit the de-watered waste into a stationary U-shaped trough.

  • Polychem - Power Skimmer

    Polychem - Power Skimmer

    A power skimmer is a 2- or 3-shaft chain and flight system designed to remove grease, scum, and other floating materials from the water surface. Similar to 2-, 3-, and 4-shaft sludge collector systems, the power skimmer is operated by a gear motor, which translates rotation to collector sprockets to drive the chain and flight system. Flights transfer the scum up a beach plate through a scraping action and discharge it into a sloped...

  • Polychem SmartGuard - Collector Monitoring System

    Polychem SmartGuard - Collector Monitoring System

    The SmartGuard Collector Monitoring System for rectangular clarifiers identifies collector system overloads that cannot be detected by traditional shear pin or torque monitoring devices. SmartGuard’s strategic placement allows it to monitor regular motion, warn of potential danger, and shut down the system before damage can occur. This cost-effective, early detection approach helps water and wastewater plants to avoid costly system...
