1. Waste Protection

2. Waste Protection We work with two types of waste :- Human waste (cake)
By product of sewage treatment process (ammonia)
Food waste
Over 6 million tonnes a year in the UK (various acids)
Two types of waste protection:
Protecting the environment
Protecting assets

3. Protecting the environment - Containment
Primary containment
Tanks used to store waste during disposal process
Secondary containment
Bund wall provides failsafe in case of primary containment failure

4. Protecting the environment
Shrewsbury (Feb 2013)
8 million litres of digestate
Primary & Secondary containment failed
River Teifi (Dec 2016)
Slurry leak into river
Thousands of fish killed

5. Protecting the environment - Bund lining
Problem
Inadequate secondary containment
Solution
Bund lining
Guaranteed structural integrity

6. Protecting assets - Not built to last
Waste transportation
Steel containers (RoRo)
Waste storage
Steel/concrete tanks

7. Protecting assets - Corrosion protection
Wessex water spend upwards of £2 million every 1-2 years on new steel containers.
Not any more … saving of around £7.2 million over 10 years.

8. Protecting assets - Corrosion protection
Corrosion hazards with Anaerobic digestion.
Hydrogen Sulphide (H2S) - up to 1500ppm
Mixed with water produces Sulphuric Acid (H2SO4)
Attacks concrete and damages steel
Often goes undetected

9. Protecting assets - Corrosion protection
Problem
Corrosion is part of the process
Solution
Long lasting protection
Guaranteed protection against chemicals
