Wastewater - Technical Breakout Room A​

Session A

10:30 - 10:55

SETTLING THE SCORE - The case for factory built, small footprint, primary settlement.
Joakim Nilsson - Jacopa

The presentation will consider the design option of providing a small footprint primary treatment process versus conventional civil works settlement tanks. Issues including Quality, Standardisation and Safety will be reviewed and performance evaluated including suspended solids removal, sludge production volume and footprint required.


Session B

11:30 - 11:55

Design and Hydraulic Details of Screens for Waste Water Treatment Plants
Dr Michael Kuhn - Kuhn GmbH c/o M&N Electrical & Mechanical Services Ltd

This presentation highlights the findings of 395 experiments carried out to study the design and hydraulic performance of screens in an open channel. It examines multiple influencing factors such as flow rate, bar spacing, bar shape, installation angle, frame and downstream water level.
When compared to the biological process of screening, the design of screens for Waste Water Treatment Plants and evaluation of their hydraulic performance has only been discussed by a small number of scientists and professional engineers dealing with wastewater.  This presentation is based on the findings of a thesis written in collaboration between Kuhn GmbH, the Institute of Physical Process Technology and the department of hydraulic engineering and water economy at the University of Applied Sciences in Saarbruecken, Germany.

Session C

13:00 - 13:25

Success with Screens at Pumping Stations 
Dale Foster – Huber Technology

This presentation will detail case histories about the successful use of screens and screening used at pumping stations to remove large items and solids from the flow, to protect the downstream equipment and process.
The presentation will look into the reasons as to why it is so important to address this area and the benefits that are gained.  This is a real problem area for the Water Industry and the pumping station failures associated with inadequate screening can lead to incidents of flooding and pollution.


Session D

14:00 - 14:25

Energy Efficiency Savings at Thames Water Reading STW
Simon Lambert - SEEPEX

SEEPEX has worked with Thames Water to improve process efficiency and reduce energy consumption of dewatered biosolids sludge handling.  Trials at Reading STW proved energy savings using new Smart Air Injection (SAI) technology of 15% - 61% compared to piston pumps.  This presentation provides details of the technology and the trial undertaken at Reading STW.​
