Vehicle washing greese and oil trap design

Vehicle washing greese and oil trap design

Vehicle washing greese and oil trap design

(OP)
Dear all,
We require vehicle washing effluent greese and oil trap design. The effluent is per day 1,000 liters. We do have an existing design (attached here). but I feel it's over designed. Request you to please throw some light on this. Please let me know the optimisation can be done to the attached design.

RE: Vehicle washing greese and oil trap design

This design is problematic. You have a sand filter in the system which will get clogged quickly with residue.

Your flow is relatively small and there are lots of commercially available oil/water separators on the market that would be more efficient and likely less expensive than building the tank you have shown.

Many oil/water separators work on a flat plate/lamellar flow process...others work by vertical baffles with liquid flowing from the bottom to top through weirs or slots at the bottom of the baffles and the oil/grease floats to the top. It is important that the flow be very slow through these devices.

RE: Vehicle washing greese and oil trap design

Funny, I was just sizing one for a 3 bay garage for our public works department. By our State Plumbing Code I show a need for a 184 gallon unit and readily found commercial units at 250 gallons. In my case I'm just filtering floor drains and am not concerned with maintaining a specific flow rate through the unit.

Engineering Report - Top 10 Defect Types in Production
This 22-page report from Instrumental identifies the most common production defect types discovered in 2020, showcases trends from 2019 to 2020, and provides insights on how to prevent potential downtime in 2021. Unlike other methods, Instrumental drives correlations between a variety of data sources to help engineers find and fix root causes. Download Now
White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
