Grease seperators advantages and uses

• Septic tanks serve to break down various waste
  materials naturally over time. Yet, they cannot
  handle liquid waste that comprises large amounts
  of greases and oils. An excess amount of oils and
  greases can impair the functioning of the septic
  tank, distribution box or the leach field
  significantly. This is why septic tanks are
  perfect for households and domestic buildings.
  But commercial kitchens in commercial properties,
  schools and various hospitality services need a
  better wastewater filtering solution.

Why Does a Commercial Kitchen Require a Grease
seperators?

• Facilities with commercial kitchens often produce
  a substantial amount of liquid and solid wastes.
  A large portion of this waste would comprise
  greases and oils. This is why commercial
  facilities do not use septic tanks for handling
  their liquid waste. Instead, they rely
  extensively on grease traps. 
• Grease traps overcome these issues easily. They
  capture these waste items before they enter the
  drainpipe. Over time, the wastewater will cool,
  while the grease will solidify. At this point,
  the wastewater will egress through a drainage
  pipe, leaving the grease inside the trap. With
  the passage of time, the trap will be full of
  solidified oils, greases and food scraps. Because
  it is full of these waste items, the trap might
  not function properly. To remedy this, the
  business owner will need to contact a grease trap
  pumping company for emptying the trap.

What are the Most Common Varieties of Grease
seperators Used These Days?

• There are three main types of grease traps or
  interceptors. These comprise
• The Hydromechanical Unit This unit relies on the
  principles of heat and gravity for separating the
  Fats, Oils and Greases (FOG) from the wastewater.
  Made of carbon steel or plastic, these units
  control the flow of water. This allows the hot
  water to cool. The baffle catches the FOG first.
  Thereafter, it stores the FOG inside the grease
  trap. However, these units require regular
  cleaning and emptying.
• The Gravity Unit This unit comprises two or more
  compartments, which use a larger amount of water
  to slow down the water inside the trap. The
  slowing of the water flow makes the FOG buoyant,
  thereby causing it to separate. These units are
  popular because they offer higher levels of
  efficiency as compared to the hydromechanical
  units. Estimates suggest that gravity units can
  collect as much as 90 percent of the FOG from the
  water. It is worth noting though, that these
  units are significantly larger than the
  hydromechanical units are.

• The Automatic Grease Removal Unit (AGRU) AGRUs
  utilize mechanical and electrical components for
  skimming the FOG from the water. Despite being
  smaller, these units offer higher levels of
  efficiency. They can eliminate as much as 99
  percent of FOG from the wastewater. They
  typically comprise internal collection devices
  for food particles, heating elements and external
  FOG collection units. AGRUs can be quite
  expensive as compared to the other two kinds of
  units. However, their higher levels of efficiency
  and lower dependencies on maintenance make them
  very popular. 
• To work at optimum levels, grease traps require
  regular emptying and cleaning. Commercial kitchen
  owners would need to utilise the services of a
  grease trap pumping company for this.

How Does a Grease seperators Work?

• As mentioned earlier, grease traps prevent FOG
  from contaminating sewer lines. They retain high
  temperature spent FOG until it cools, thereby
  enabling the separation of the solidified FOG
  from the wastewater to occur. In addition, they
  also retain large particle solids, which
  typically settle at the bottom of the trap. When
  a grease trap service company comes to clean the
  trap, it will empty the trap of these large
  solids and the solidified FOG.
• It is worth noting that grease traps have no
  direct connections with the drain of the sink
  that it is filtering. Instead, these traps
  feature a flow control valve. This valve keeps
  the water from reaching the grease trap too
  quickly before the trap itself. In addition, the
  trap will not have any filter that keeps the FOG
  and large particles out of the water. Moreover,
  the distance between the drains and the grease
  traps serves a specific purpose too. It enables
  the water to cool on its way to the trap.

• As the wastewater cools, the large particle
  solids will sink to the bottom of the trap.
  Similarly, the FOG will float at the top of the
  trap. In short, the grease trap is a receptacle
  that keeps the FOG floating at the top of the
  water, by making the water fill the well. 
• It is worth noting that a wall travels part of
  the way down the well on the input side. This
  ensures that the water needs to pass under this
  wall for exiting through the drain. Because the
  FOG floats, it cannot travel towards the drain.
  Similarly, because the larger particles are
  heavy, they sink to the bottom and cannot travel
  up to the drain on the other side of the wall. A
  grease trap cleaning company will remove both
  these waste items from the trap while emptying
  it.
