Drain-Life Dosing in Ras al-Khaimah Hotel

Drain-Life Dosing in Ras al-Khaimah Hotel

In August 2016, Tetra was invited by a Marjan Island hotel in Ras al-Khaimah to conduct a short trial of the Drain-Life Grease Eradication System. Despite having an existing Grease Eradication Program from another company, the hotel was experiencing problems with FOG accumulation in the drainage network and high Biological and Chemical Oxygen Demand of its grease trap effluent, an issue which was brought to the attention of the local sewage authority.

Tetra replaced 7 dosing systems in the main kitchen with Drain-Life Microbial Grease Digester. Wastewater samples from the external main grease trap were taken at T = 0 days and T = 11 days and BOD and COD were analyzed by an independent laboratory. Drain line camera inspections were also conducted at these points.

After 11 days of dosing with Drain-Life, BOD and COD in the grease trap was reduced by 62% and 67% respectively.

Drain line camera inspections show that grease accumulation in kitchen drain lines was reduced from 40% to around 10% over the same period.
