Concepts & Ideas of Importance



What Do You Want From Your WwTP?


Here’s the things I would look for: q Effluent quality q Community presence q O&M costs & sustainability q Robust & proven q Expandable to match growth



Effluent Quality: Technologies which….


• Ensure a high quality treatment consistently • Enables ability to reuse effluent • Provides future protection against regulatory

change



Community Presence: Technologies which…..


• Minimize footprint required • Maximize ability to hide



O&M Costs: Technologies which…


• Minimize labour requirements • Enable resource recovery to:

– offset energy – make use of bio-solids and waste streams



Expandable: Technologies which…


• Provide cost effective treatment for Day 1 • Easily expandable for year 20 • Expandable in increments to match growth

Our Technologies



Technologies which achieve the goals


• Primary Treatment: LEAP Primary • Secondary Treatment: LEAP Membrane Bioreactor • Solids Treatment: Advanced Anaerobic Digestion

Primary Treatment



LEAP Primary – Why Do We Want Primary Treatment?

Energy Savings •  Primary treatment removes TSS & BOD from raw wastewater •  Reduced organic load results in energy savings of 25% for

biological treatment

Resource Recovery • Primary treatment captures solids with high energy value

• Retained solids enable energy recovery with anaerobic digestion, incineration or other solids treatment

Primary Treatment with LEAPprimary

LEAPprimary replaces the function of primary clarification and fine screening in a typical primary treatment system

LEAP Primary

Coarse Screening

Bioreactor Coarse Screening



LEAP Primary •  Influent TSS forms a filter mat on the mesh belt •  TSS and BOD is retained by the filter mat •  Solids are removed from the belt

Capital Savings Reduce primary treatment capital costs for your facility

Energy Savings Reduce energy for biological treatment by 25% and enable energy recovery

Smaller Footprint Achieve advanced primary treatment in as little as 1/10th the footprint of conventional

Simplified Design Combine primary solids separation, sludge thickening & dewatering in one compact step

Guaranteed Reliability Extend downstream equipment life with enhanced influent solids screening

LEAP Primary - Benefits Summary

Secondary (Tertiary) Treatment



LEAP MBR: Why Do We Want MBR?


Footprint •  Plant footprint 1/3 conventional activated

sludge process Quality & Reliability

•  Process that consistently produces high quality effluent

Aesthetics

•  Smaller tanks are easy to hide & cover

Construction Costs

•  MBR requires less concrete and less volume/weight to support

•  Modular design allows for easier expansion

What Is a Membrane?

Modular In Nature

MBR Effluent Quality GE MBR effluent is used in

conjunction

with all major water reuse standards:

•  WHO standards for unlimited irrigation

•  International Maritime Organization bacteriological limits

•  EU bathing Water Directive

•  California Title 22 Code of Regulations

MBR: Used commonly for reuse water but also in areas which are sensitive receiving streams. Effluent quality could be as low as: • BOD <5, TSS <5, NH3-N <0.5, • Total Nitrogen <5, Total Phosphorus <0.15 • Turbidity <0.1NTU • High UVT 70% • Many plants no longer using UV systems for disinfection



Expandable…


• Simply add cassettes for minor flow expansions • Simply add trains for major flow expansion



Community Presence…..


• Ability to hide…a beautiful house….





• Look a little closer, this is a wastewater treatment plant…..5MLD WWTP





• A beautiful farm…20MLD WWTP

Solids Treatment



Advanced Digestion: Why Do We Want Advanced Digestion?


•  Treatment of waste streams generated in the process •  Treatment of solids so they can be disposed of safely •  Resource recovery – generation of biogas for energy

Technology Summary



The End Result: A WWTP which…

Anaerobic Digestion LEAP Primary LEAP MBR

•  Produces high quality effluent with future protection and water reuse capabilities.

•  Treats its own waste streams and other waste streams as well

•  Is compact and can fit into the community •  Can be energy neutral or even energy positive
