Best Practices for Wastewater Screening Design The Use of Weirs to Optimize Screen Design Wastewater screening is the crucial first step in the wastewater treatment process, designed to remove large solid materials and debris from the influent wastewater. This process is essential to safeguard downstream treatment units and prevent potential equipment damage, operational inefficiencies, and… Continue reading Guide to Wastewater Screening Design

Preliminary wastewater treatment requires a two-step process: screening to remove large debris and trash and grit removal to eliminate the smaller, heavy sandy particles from the influent.

What are Packaged Headworks Systems?
The screening and grit removal technologies presented in our last blog can be combined into several arrangements to integrate screening and grit removal to create a package headworks system. Most systems on the market have a screening section followed by a separate grit removal section.

Packaged headworks for wastewater treatment combine the preliminary treatment processes of screening to remove large debris and grit removal to eliminate smaller, heavier particles like sand, bone fragments, and ground debris.

In our previous post, we looked at the role that center flow and drums screens play in supporting MBR systems in wastewater treatment facilities. Now, we’d like to focus on the lessons we at Hydro-Dyne have learned over years of retrofitting other screening systems. Below, we share the knowledge we’ve gained from designing new systems for a variety of plants (MBR or otherwise).

A membrane bioreactor, or MBR, is a wastewater treatment process that combines a microfiltration or ultrafiltration process with a suspended growth biological reactor. Membrane systems require influent to be treated with ultra-fine screens with openings that are usually 2mm or less. This protection is important to remove the inorganic trash, fibers, and hair present in the wastewater stream before they get into the tank. Once in the membrane tank, they have no place to go.

At Hydro-Dyne, we only focus on screening headworks systems, so our knowledge in this area is at the highest level and depth you could ask for. We are committed to advancing screening technology and grit removal technology.

We recently explained how you can prevent corrosion in your headworks. We also let you know about how we treat the stainless steel we use to create the headworks equipment for wastewater treatment facilities around the world.

A poorly functioning wastewater screening system will lead to higher maintenance costs – and possibly catastrophic results for your facility and those it serves. Even if you avoid a total shutdown, those costs can eat significantly into your overall facility budget and cause your operations to be expensively inefficient. When equipment fails because you have an inadequate system, the downtime compromises your mission. But all of that is avoidable.

Your facility relies on its headworks to function as designed. Corrosion is one of the factors that can undermine this mission and affect the performance your entire wastewater treatment process.
