LongBox Clarifiers

Newterra LongBox Clarifiers offer you modular, high-flow sediment and suspended-solids removal on groundwater treatment and dewatering projects. These innovative, rectangular clarifiers are also extremely well suited for potable water pretreatment, and the treatment of process water, mine groundwater and wastewater. They offer almost three times the settling area of conventional weir tanks more than twice their size, and 25% more settling area than similarly sized conventional tube.

Product Overview

Available with tube settlers or inclined plates, Newterra LongBox Clarifiers provide excellent removal efficiencies compared to traditional weir tanks and settling or frac tanks commonly used for sediment treatment on construction sites and in other applications.  They are built for easy transport on flat-bed trucks to sites and remote areas. Once on location, installation, setup and operation are fast and simple – even on uneven ground.

Features

Quick Leveling On-Site: Newterra LongBox Clarifiers allow simple field adjustments to accommodate non-level ground up +/-2” on the width of the tank and +/-4” across the length of the tank.

Operator Access Platform: : A integrated, fold-away catwalk provides safe, convenient access to the top of the clarifiers for inspection, determining sludge depth, cleaning and operational adjustments.

Easy-Access Sludge Removal: Side access to the clarifier allows access to the sludge below the clarifier media while standing on the operator access platform.

Higher Solids Load Handling Capacity: The innovative design features a shorter plate pack – allowing tighter plate spacing than long or tall lamella clarifiers.

Quiescent Settling Zone Configuration: Sludge from the quiescent zone and plate pack fall into same location for easier sludge removal.

Carbon Steel Construction: Sand-blasted epoxy liner provides long-term chemical resistance. Other materials of construction are available.

Newterra Sludge Extractor: This flexible, broom-like wand features a suction head for easy removal of sludge from below the clarifier media.
