New Developments Chronicled with WEFTEC InterWEBviews™
Over the last several weeks we have conducted many hours of InterWEBviews™ and learned about new hardware, new systems, and new solutions to wastewater problems. The InterWEBview™ is a great way to learn about the latest technology.
Here is a list of InterWEBviews™ available so click and view and let us know what you think of this new journalistic tool.

InterWEBview™ Summary |
|
Acme Engineering Products
|
1819 |
Acme scraper type strainer is a low maintenance option for particles larger than 75 microns. It is effective as a pre-filter for a MBR in wastewater. It is effective when seawater is used for cooling. The housing can be constructed of FRP with monel internals for corrosive applications. |
|
Alfa Laval
|
2627 |
The ALDEC G3 is built around the Slimline design – a breakthrough in decanter centrifuge performance and capabilities. The smaller conveyor diameter makes room for more liquid in the pond, and allows higher bowl wall pressures, resulting in either drier cake or using less polymer. Patented Alfa Laval Power Plates also effectively reduce the power consumption of ALDEC G3 decanter centrifuges, making a big contribution to cost savings. The supply on a skid cuts erection costs and insures system integration. |

A new thermoplastic valve can easily replace existing cast iron valves in wastewater treatment plants. It can increase the replacement interval in corrosive applications to 5 years instead of 1. The slight price premium is quickly offset by not only by the reduced number of valves purchased over the lifetime but also the reduction in maintenance replacement labor. The new design can easily fit in to the space occupied by the existing valve. |

Packaged and field erected sewage treatment plants address phosphorous, nitrogen and total suspended solids. The new screenless Strata Sand filter is achieving high efficiency with low maintenance requirements. |
|
Atlas Copco |
1151 |
The screw compressors now installed in many wastewater plants in Europe and some plants here in the U.S. are demonstrating that at no more capital cost/cfm energy consumption can be reduced by 30% or more and therefore greatly reducing life cycle costs of aeration. |
|
BDP Industries
|
6827 |
The BDP belt press is unique in its layout. The gravity belt is at waist level and therefore no platform is needed. The rolls are placed vertically the advantage is the potential for direct discharge into a truck. |
|
Bord na Mona
|

Flat plate membrane bioreactor has advantages of low maintenance. Biological treatment with coarse bubbles combined with the fixed bed result in better contact at lower energy consumption. The use of waste clam shells from the food industry for use in the odor removal system provides effective H2S capture with low pressure drop due to the use of the complete shells. |
|
Bright Technologies
|
4649 |
Bright belt presses are constructed of stainless steel for longer life and lower maintenance. A number of patented features enhance the performance. |
|
Charter Machine Co. |
7644 |
The Sentry press has the capability to vary the speed of the gravity belt independently of the speed of the press belt. The result is drier solids and more flexibility including modes where just the gravity belt operates for thickening purposes. |
|
Dresser ROOTS |
5713 |
InterWEBview™ pending Dresser Roots compressors and blowers are widely used in the wastewater industry. Their WEFTEC promotional slogan is “innovation that will blow you away”. There are developments, such as IntelliView Controls, to provide system efficiency and ease of use. In general, ROOTS blowers are used on smaller applications and their centrifugal compressors on the larger ones. |
|
Festo |
7739 |
Festo is a worldwide automation company. In the field of process automation. They supply systems incorporating their pneumatic actuators. Pneumatics offer substantial reductions in life cycle costs. The pneumatic approach from Festo is being incorporated in the skids of filter suppliers and is being adopted by increasing numbers of wastewater plants. A total solutions approach including the valves and other components is attractive to the engineers and system suppliers. |
|
Gardner Denver
|
4612 & 2851 |
The Hoffman Revolution will be unveiled at Stand 4612 on Monday, October 4th. This high speed centrifugal is designed as the world’s most advanced energy management blower system according to the company. A wide range of Gardner Denver products will be on display at stand 2851. |
|
Grundfos |
5039 |
The launch of Grundfos Pumps Wastewater Business Unit and the introduction of Grundfos Pumps new S-range and SL Pumps, along with new Dedicated Controls. Also introducing SmartDigital for the dosing and disinfection market. Grundfos has a full wastewater package solution with submersible pumps, mixers for sludge and aeration, and dedicated plc controls, scada and monitoring devices. |
|
Kemira Water Solutions, Inc. |
3371 |
Kemira offers chemicals and services for a wide range of applications in municipal wastewater. Phosphorous control is an area of increased activity. Kemira is one of the largest suppliers of flocculants and coagulants and works closely with suppliers of dewatering equipment to optimize performance and cost. For H2S, control measurement equipment is included along with the chemicals and other services. The package allows the operator to achieve the desired removal with the right amount of chemicals. |

Ovivo Water |

For anaerobic digestion, the LM™ (Linear Motion) Mixers offer solutions to the challenges of mixing wastewater in both thin sludge and thick sludge applications, providing homogeneous mixing by creating a turbulent liquid-core of micro and macro eddy currents. The result is less energy consumption and more energy produced in the form of biogas. A 3 membrane gas holder provides large and secure storage of biogas. The EWT™ Sonolyzer™ ultrasound technology achieves effective sludge reduction. The advantage of ultrasound treatment is that it does not require chemicals or extreme environmental conditions (either pressure or temperature). Ultrasound treatment disintegrates the sludge through a process known as “ultrasonic cavitation”. |

Seepex |
3043 |
RSmart stator technology cuts down the replacement time for these progressing cavity pumps which are used to feed both sludge to the dewatering centrifuges and presses and to convey the dewatered sludge with up to 45% solids. |

World Water Works |
6319 |
The Waterworld DAF system has a Reduced Footprint, Maximum Solids Recovery, Minimum Operational and Reduced capital cost. The moving bed biofilm reactor is efficient and cost effective. |
