Complete Blower Package Results In Quiet Operation, Easy Maintenance

Until 2012, the Kaufman, TX, Wastewater Treatment Plant (WWTP) operated two separate aeration basins with mechanical surface aerators. As the plant’s equipment aged and required more frequent and expensive repairs and maintenance, the City of Kaufman followed its engineering firm’s recommendation to install a new, more efficient, fine bubble-diffused air system rather than simply replacing its old mixers with in-kind equipment.

RWL Water Provides Dissolved Air Flotation Technology To The Industrial And Municipal Sectors RWL Water Provides Dissolved Air Flotation Technology To The Industrial And Municipal Sectors

Dissolved Air Flotation (DAF) is a physical/chemical technology designed to treat wastewater containing particles that are slow settling, of neutral density, or buoyant. The DAF works by producing a stream of micro-fine bubbles that attach to solids and lift the solids to the surface where they can be removed by a surface scraping mechanism. This technology is particularly applicable to food and other industries where solids are fluffy, light and slow to settle such as fats, oils and greases. Our systems are designed and customized to handle a wide variety of influent water quality and flow rate. RWL Water provides robust systems that have a small footprint, and are easy to install, operate, service and clean.

System controls are critical to a wastewater blower system. Without them, a system with multiple blowers operating on their individual controls will run more than necessary and result in wasted energy. Maintenance costs increase and worst of all: process performance suffers.

Jet Aeration Jet Aeration
The Mass Transfer Systems bi-directional jet aerators are designed with jet aeration nozzles installed on both sides of the liquid / air jet aeration manifold. This configuration is most applicable for square or rectanglular tanks, larger lagoons, and sequence batch reactors where directional flow patterns are not desired

Energy Efficiency Boosted By Replacing Controls Not Blowers Energy Efficiency Boosted By Replacing Controls Not Blowers

At the wastewater treatment facility, the biggest energy consumer is almost always the multistage aeration blowers. Replacing these blowers with high speed turbo blowers can save energy but the short-term cost to replace the existing blowers, reroute pipe and set new foundations can make the change a hard sell.

ABOUT AERATION

 

A common first step in the secondary treatment process is to send wastewater to an aeration tank. In an aeration tank, bacterium is used to effectively break down pollutants into less harmful components. Wastewater aeration provides the appropriate oxygen level so that aerobic bacteria can thrive in degrading pollutants such as iron and manganese as part of the wastewater treatment process. Aeration can also be used to destroy anaerobic bacteria that perish in the presence of oxygen. Aerobes that can break down pollutants 10-100 times faster than anaerobes are used most frequently.

Aeration is also used to improve waste lagoons and other waterways such as lakes and reservoirs where oxygen deficiency contributes to taste, odor and pollutant problems. Equipment used for wastewater aeration includes low cascades, jet fountains, spray nozzles, blowers, submerged perforated pipe and porous plates or tubes. Whether the water is thrown into the air via a fountain or diffused by air bubbles being blown or drawn into the wastewater in an aeration tank, aeration works by increasing the area of contact between the oxygen in the air and water.

The most common wastewater aeration process in use today is the air diffusion process, where air is introduced from blowers through diffusion tubes suspended in a spiral flow tank, or in some cases, through diffuser plates in the bottom of the aeration tanks.
