Get the solids out...

• Filter with the wash pad– Everything dissolves in water.– Settled solids go anaerobic causing odors– Settled solids in a separator or pit collect more TPH,

Metals and COD making the disposal most costly.– Keep the solids from entering the system initially.– The less solids that enter the system, the less the user has

to remove from the system. LESS MAINTENANCE AND COST!!!!!

– Maintenance Instructions to the user is very important!!

Theory of Solids Separation

• Three Stage Separator– Capacity = 600 gallons

True to Life Solids Separation

• Three Stage Separator– Capacity = 60 gallons

True to Life Solids Separation

Although these separators work there are problems with their use.

• Sight unseen

• If in ground, the removal of solids becomes difficult so it wont be done.

• They harbor biological growth

Logistics

• Where are you?– Freeze potential– Rain patterns– Clay or Sand

• Covered or uncovered wash pad• Overflow to sanitary sewer or tank

What are you washing & washing off?

• Sand, clay, heavily organic soils

• Sanitary waste equipment or leachate

• Grass/HIP’s

• Heavy grease/oil, solvents

• Fertilizer

• Tank wash outs

System Basics

Gallons per minute Gallons per hour Gallons per day Hours per day demand Days per week demand Sanitary sewer availability Discharge or recycle

Site Evaluation Form

• It’s about communication

• It’s about buy-in (Customer Commitment)

• The beginning of the installation history

• Good planning

• Project guide

• Making the form do more for your project

Site Evaluation Form

• Electrical Requirements– Voltage

• 120, 208, 230, 460

– 1 or 3 phase– Amperage load

• Space• Flow rates• Usage level

Site Evaluation Form

• Chemicals– Lower water quality– Address application, now– Limit the number of chemicals used– Some uses may be eliminated

• Save money with conservation

• Discuss & note expected frequency of system cleaning and maintenance

Site Evaluation Form

• Learn from previous projects• Take your time with this step• Take digital photos• Typically this is rushed or skipped

Heavy Equipment Rental

• Look for large volumes of solids /Chem– Design the wash pad to filter the solids– Look for chemicals that are used to keep

equipment clean during the rental period– Look at each location and inquire about where

the equipment is being rented to
