Tricel Wastewater treatment 

As the wastewater collected comes from toilets, showers, sinks, washing machines, dishwashers, etc., one can find a number of different pollutants contained within.

For this reason, in cases where the domestic wastewater treatment system is not designed correctly or appropriately operated, the effluent can pollute the local environment. Such issues result in damaged wells or water sources and cause problems for public health.

How to determine the size of your wastewater treatment ?

To calculate the size of individual sanitation. We will use a common metric. In Ireland, this metric is the equivalent to the population count

What is Population Equivalent or PE ? According to the definition of the OECD “Population equivalent (in waste-water monitoring and treatment) refers to the amount of oxygen—demanding substances whose oxygen consumption during biodegradation equals the average oxygen demand of the wastewater produced by one person”. To calculate we assume that one unit equals 60 grams of BOD per 24 hours.

How to calculate the population equivalent ?

The population equivalent will be calculated with the number of bedrooms in the house. This calculation is from the Code of Practice: Waste Water Treatment and Disposal Systems serving Single Houses for all installations inferior to 10 PE. The table below is going to summarize the calculation.

Why it’s important to determine the size of your sanitation Determining the size of your installation is essential. You probably think that any tank will do the trick. What is any sanitation product to suit your home? It’s wrong. To have sanitation standards, you must have a powerful product and a suitable size. What is the problem if my installation is not the right size? We will together look at the two possibilities below:

if your product is undersized, you may not get sufficient sanitizer quality if you choose an under-sized product. In fact, the wastewater must remain in the tank for a given period. If the product is too small, the amount of wastewater will increase, which will shorten the settling time and reduce water quality. This could also have negative consequences on the secondary sludge.

If your product is oversized: do you think having a larger product can reduce the number of desludging? You are right, but too oversized its product can also have negative consequences. Indeed, if the size is too large, the treatment quality will drop because there will not be enough wastewater supply for the treatment processes. The number of bacteria will not be enough to treat wastewater properly and have a sufficient effluent quality. (this is true only for wastewater treatment plants. For septic tanks, being too big is not a problem).

You understand determining the size of your product is an important step. For any request about a sewage treatment plant, contact your Tricel technician.

What is PE ?

PE represents the initials of Population Equivalent. Population equivalent: conversion value which aims at expressing non-domestic applications in terms of domestic loading based on 1 person creates 60 g/day BOD5 and 150l/day.
