First Milk Dairy Effluent

Client:First Milk
Suspended Solids Removal:85%
COD Removal:60%

Background

First Milk produces a wide range of dairy foods, including cheeses, raw milk, butter, and skimmed milk powder, for national and export markets.

They needed to replace the existing DAF unit at its Haverfordwest site during a busy period and with limited space. The work needed to be complete without disruption to production.

The Overall Objective

The existing DAF unit had become unreliable due to its age, but performed an essential duty by protecting the downstream biological stage from the effects of suspended solids, fats and associated COD. The replacement DAF needed to occupy a small footprint yet offer similar or greater capacity that the original unit. The switchover needed to be carried out in a matter of hours.

Solution

Siltbuster’s D100 packaged lamella DAF unit was delivered and positioned on site, with site assembly time minimised due to the pre-packaged design of the equipment. Once the equipment was ready, the final tie ins was conducted with a matter of hours, ensuring no disruption to production.

Performance was enhanced compared to the original DAF, with typically 85% suspended solids removal and 60% total COD removal.
