Brentwood Industries, Inc. products

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.

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.

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 trough and generating a flushing action to discharge collected material.

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.

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.

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.

Complexities such as stringent discharge limits, space constraints, and regional variations present a growing burden for plants facing demands to treat greater flows. Brentwood’s AccuFAS FBBR system offers a flexible solution for facilities requiring greater treatment capacity in existing basins, better nitrification with consistent seasonal performance, and biological nutrient removal to meet strict effluent total nitrogen limits. For industrial wastewater applications, such as food and beverage or poultry processing, Brentwood provides high-strength BOD roughing or full treatment.

A time-tested technology, trickling filters offer a simple, cost-effective, energy-efficient treatment solution. With more than 500 trickling filter installations worldwide, Brentwood’s media and components have been optimized to guarantee the best performance for any application. By maximizing surface area in a given volume, Brentwood’s structured-sheet media provides an ideal environment for microorganism growth.
