Undersink Dilution Trap

The Halgan Under Sink Dilution Tank is used for the treatment of waste water from laboratories, schools, technical colleges or any application where acids or alkalinise are used.

Averaging Dilution Tanks

Halgan’s Averaging Dilution Tank is used to average/neutralise acidic/alkaline waste water prior to discharging to the sewer system. The inlet and outlet design provide a swirling effect in the flow of the waste water which assists in mixing within the Pit.

Cooling Pits

The Halgan Acid Neutralising Trap is used to stabilise pH levels of waste water that may contain high levels of acid before it is discharged into the sewer.

Clay Plaster Trap

The Halgan Clay/Plaster Trap is used for the treatment of waste water from dental surgeries, doctor’s surgeries, jewellers, technical colleges, schools, craft or facilities that use clay and plaster.

Fish Scale Trap

The Halgan Difference

Halgan provides custom grease traps to help any business find the perfect solution, whether you’re undergoing expansion, undertaking a renovation or starting from scratch. There is a wide range of grease trap sizes on the market, and Halgan is prepared to find the right one for you. Consider what size will suit your needs best, as a trap that is too large will waste space and may be an unnecessary cost to your business.

We offer small grease traps that can be installed simply and without too much cost to you, as no advanced lifting equipment is required. Alternatively, we can supply large grease traps that are perfect for large restaurants or butchers with a huge output of grease and oil.

Halgan grease traps meet all relevant certification requirements, including Green Star, Standards Australia WaterMark Certification, and Water Services Association of Australia (WSAA). On top of this, we have become the first pre treatment manufacturer in Australia to achieve AS-NZS 1546.1 Certification for some of our modular grease traps.
