Trash Pumps Engineers Edge

Trash pumps, also referred to as sludge pumps, grinder pumps, chopper pumps, or wastewater pumps, are designed to handle solidsladen fluids. These could include trash, mud, natural debris, fish and animal processing plant waste, and fluids containing sand, gravel, crushed stone, and concrete chips from construction sites.

Trash Rack, Trash Racks, Debris Screen, Trash Guard J.R. Hoe

A Trash Rack is a fabried steel component designed to block floating debris from entering stormwater and wastewater systems. Often featured on precast concrete outlet structures in stormwater retention and detention ponds, trash racks play an essential role in water management systems. Our trash racks are designed for efficient flow and successful screening of debris at inflow and outflow

Wastewater Pump Station Design Problems and Solutions

2014626&ensp·&enspProblem: Common pump station design practice over the past 50 years has been to provide two pumps sized for the peak design flow rate, one of which is a standby pump. For pump stations with long force mains, the friction loss when operating at the design peak flow rate is excessive, resulting in high energy costs.

However, plants utilizing mechanically cleaned screens should have a standby screen to put in operation when the primary screening device is out of service. This is standard design practice for most newly designed plants. Source: Crites and Tchobanoglous, 1998.

Inverted Siphon. Depressed Sewer. Design Calculations

Units: cm=centimeter, cfs=cubic feet per second, ft=feet, gpm=US gallons per minute, gph=US gallons per hour, gpd=US gallons per day, m=meters, MGD=Millions of US gallons per day, s=second Inverted siphons (also called depressed sewers) allow stormwater or wastewater sewers to pass under obstructions such as rivers. Our inverted siphon calculation allows up to five parallel siphons to go

HydraSieve Static screen for solid / liquid separation

The screen plate is supported by a frame which initially ensures quietness and even distribution of the effluent over the entire width of the unit and then accelerates the liquid down the screen plate. The filtered liquid is collected in the screen base. The screen plate and the frame form the HydraSieve screen.
