Introduction The Principle

The VGS Grease Separator has revolutionized
greasy wastewater generated by the preparation
of food. Impurities from the water. This allows high density
contanimants to fall into a sludge retaining area at the bottom
This system has been developed to
solids and non emulsified grease and oil
wastewater. Is also removes most of the
and suspended solids. As a direct result, other
wastewater quality indicators are improved,
which include BOD (biological oxygen demand)
ammonia pH, Phosphorous, Sulphate and Nitrogen.

The Problem

Organizations that process or prepare food, generate
large amounts of trade waste containing grease and oil,
suspended solids and numerous other pollutants. This
wastewater is known as “Greasy Water”.

The current water authority policies require these
organizations to install onsite pre-treatment equipment
to improve the quality of greasy water prior to discharge
into the sewer system.

Grease traps progressively become less efficient, as grease,
oil and sludge accumulate. Regular cleaning of these pits
along with frequent pump outs are required to prevent
blockages, odor problems and health hazards.

The quality of wastewater discharged as trade waste can be
used by water authorities to charge food outlets for their
trade waste output. Fees and charges are calculated by the
quality and quantity of water discharged to sewer. If the
quality does not meet with the authorities guidelines then
associated fees and charges can be very costly

The VGS Grease Separator operates by ingenious control of both fluid velocity and pressure which gently coaxes effectively of the vessel, and for the free grease and oil and low densityin suspended solids to rise to the top section of the VGS heavy Grease Separator where it flows into a grease retaining tank.

The VGS Grease Separator offers the following benefits

• Unique system that continuously looks after itself
• Significantly improved quality of wastewater
• Reduced authority charges for wastewater quality and quantity
• Major reduction in the number of costly pit pump-outs (can be reduced to 2 per annum in some installations)
• Eliminates bacteria build up such as the ever common bacterial cellulose
• Reduced drain blockages and therefore reduces plumbing costs (by eliminating the grease in the drains and screening out solids, there is less likelihood of blockages to occur)
• Treated water can be recycled to save costs
• Available in a range of flows up to 1,000 gph
• Manufactured in all 316 stainless steel

Peformance

Testing has proved that the VGS Grease Separator system compared to existing grease traps, will greatly improve the quality of wastewater being discharged to sewer by conservatively 90% and better.

The VGS Grease Separator system is set on a pre determined time frame to automatically and continuously clean itself by removing the sludge build up from the bottom of the VGS tank, and to also backflush and clean the VGS spiral pack. Depending on the application a compulsory maintenance program is set out where by the holding pit screens and inline pump filters are serviced on a regular basis.
