Wise Words

Water is the basis of life and the blue arteries of the earth! Everything in the non-marine environment depends on freshwater to survive.

Sewage Treatment

At O'Brien Water Services we are approved distributors of Tricel Wastewater Systems. Tricel is recognized as one of the market leaders in the treatment of wastewater in Ireland. The Tricel is a relatively trouble free system with no moving parts in the actual tank itself.

 

The Waste Water Treatment Process.
1. Primary Settlement 2. Aeration 3. Final Settlement.

Stage 1.
Stage1 takes place in the primary settlement chamber where the wastewater is introduced. The solids drop to the bottom and are separated from the liquid. Anaerobic breakdown now begins to occur and improves the water quality.
Stage 2.
Stage 2 takes place in the aeration chamber where masses of naturally occurring bacteria inhabit specially designed filter media. These bacteria are sustained with air, which is continuously supplied from a purpose built pump in the top section of the unit. As the liquid flows through the filter media the bacteria feed on the impurities, consuming them, thus removing them from the liquid.
Stage 3.
The liquid now flows from the aeration chamber to the final settlement chamber. Small quantities of bacteria known as sludge are carried with the liquid at this stage. This sludge settles towards the bottom of the final settlement chamber where a continuous sludge return system pumps back to chamber 1. The remaining treated liquid now meets the required standard to be safely passed out of the treatment system.

Achieving European Standard EN12566-3
The Tricel® Sewage Treatment Systems have successfully passed these tests and is now approved to the New European standard EN 12566-3 Small wastewater treatment systems for up to 50 PT-Part 3: Packaged and/or site assembled domestic wastewater treatment plants.
The Tricel® system was placed through a rigorous 38-week test, by the certifier laboratory PIA GmbH-Testing Institute for Wastewater Technology in Aachen, Germany. The Biological tests carried out in Aachen on the Tricel® system provides us the knowledge that our product is still the best in the business with a treatment efficiency of 95.7% for BOD5 and 95.4% for S:S. Structural testing (leak test, crush test & durability test) was carried out by PIA staff at our headquarters in Killarney and the range of tanks up to P50 successfully passed all of the required tests.
