Averaging Dilution Tanks

The Halgan Averaging Dilution Pit is used for treatment of waste water from laboratories, schools, technical colleges, battery manufacturing or any application where acids or alkalines are used.
The sizing of the Halgan Averaging Dilution Pit  is calculated by adding total number of laboratory sinks and multiply by 5 litres e.g. 70 sinks x 5 = 350 litres. Allow 5 litres for every 300 mm length of laboratory troughs e.g. Trough length 3000 mm divided by 300 mm = 10 x 5 litres = 50 litres. Add the estimate flow from all fixtures to calculate Halgan Averaging Dilution Pit capacity e.g. sinks 350 litres + troughs 50 litres = 400 litres – Halgan Averaging Dilution Pit size is 400 litres  In other cases 1 hour retention should be allowed for.

Halgan Averaging Dilution Pit is manufactured from Polyethylene.

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.
