Can Line Packer – 12pk History

  • Why Pretreatment System

– BOD Loading

  • Spikes in excess of 8,000 mg/L

– Phosphorus

  • As high as 50 mg/L

– Low pH

  • Acidic products, pH below 5

– Fluctuations Throughout the Day

  • High Sugar Days
  • Low Flow during Plant Downtime
  • High Flow during Production
  • Chemical Flow during Night

History

  • Constraints

– Lack of Land Space – High Priority on “Clean” Effluent – Fluctuations in Flow from Production Facility

  • Initial Attempts

– High BOD Capture for Slow-Release – Reduction of Waste Streams

MBR Installation

  • Membrane System Installed

– Maintain Healthy Biomass to Consume ‘sugar’ – Small Footprint – Very Clean Discharge

  • What is it?

– Many Small Membranes to Filter Out Clean Water – Hollow Fiber Tubes with Nominal Pore Size of 0.04µm

MBR Installation

  • Overall System

– Two Lift Stations – Equalization Basin – Aeration Basin (Digester) – Membrane Cassettes – Belt Press – Design flow rate 160,000 gallons per day, 220,000 gal. max

Permeate Flow to City of Howell Challenges

  • Fragile Sludge
  • Fluctuations in Sugar Loading

and Plant Flow

  • Solids Removal
  • High Oxygen Requirement
slide-18
SLIDE 18

Challenges: Fragile Sludge

Started with Feed-Back Control

– To ensure healthy biomass 100:5:1 ratio required (Carbon/Nitrogen/Phosphorus) – Phosphorus needs met with flow characteristics – Aqueous Ammonia added to Equalization Basin based on TOC Anaylzer results

Challenges: Fragile Sludge

TOC Analyzer

– Real time analysis of Total Organic Carbon of Equalization Basin

  • Total Organic Carbon: Amount of carbon bound in an
  • rganic compound and is often used as an indicator of

water quality

  • Rapid and accurate alternative to COD (chemical
  • xygen demand)

– Programming

  • Dose Aqueous Ammonia as TOC increases
  • Challenges:
  • Analyzer requires large amount of maintenance
  • Expensive to maintain
  • Cannot react quickly to large and quick increases of

TOC

Challenges: Fluctuations in Sugar Loading and Plant Flow

Fluctuations

– Plant runs 16-20 hours per day of various sugar and non sugar products – During off hours, cleaning is completed with large amounts of water and chemicals – Weekends with no plant production = no sugar for biology for 2+ days

  • Challenges:
  • Constant awareness of sugar loading
  • Addition of sugar during periods of plant downtime
  • Minimal sugar = death of biology

Challenges: Solids Removal

Filter press upgrade Spring 2008 – Double belt press

– Press wash water uses system water (reducing loading, increasing efficiency) – Change in polymer (custom blended) and Custom feed equipment built May 2008 – Solids exiting press transitioned from 5-6% up to 10-13% and have reached 14-17% – Flow across press has moved from 8-10 gpm to 30-50 gpm and now runs at 90-110 gpm. – Mixed Liquor Suspended Solids (MLSS) dropping to desired levels

  • f 7000-9000 ppm
  • Challenges:

– Expensive to haul away solids – Currently solids are not being recycled – looking into an alternative use for the solids

20 Challenges: High Oxygen Requirement

Aeration Upgrade – Two 150 HP blower motors running continuously (previously one 100HP blower) – Electrical upgrade to support blowers Increased Testing – TOC/COD, NH3, permeate testing – Automatic pH control – CST (Capillary Suction Time) monitoring

CST and associated permeability
