Holding Tank Sewage Treatment with BioTherm Eliminator
With the newly tightened environmental laws regarding sewage disposal for marine, motor homes, farms, trains, planes, etc. into holding tanks, the problem of odour control was a challenge, until now. The very nature of sewage itself and how it breaks down is fairly basic, so when we apply the principles of safe waste water treatment with BioTherm Eliminator, sewage resolves itself into a stench free system with clean tanks, piping, and operational accessories, which can be drained without trouble.
In order to speed up the sewage breakdown into liquid and eliminate odour; to clean the lines, fittings, valves, and tanks of the sewage debris which will cling to the walls and become a build-up and possible blockage in the lines, we need to add a small amount of BioTherm Eliminator into the system. BioTherm is an environmentally safe catalyst that eliminates the sewage stench, dissolves human and animal excrement, toilet tissues and animal roughage, and breaks down the hard calcium/magnesium deposits called Struvite, all of which tend to clog lines, tanks, septic fields, etc. BioTherm then flushes it all out as dissolved waste water. BioTherm Eliminator behaves like enzymes but without their limitations (enzyme catalysts have a limited success rate due to their biological limits to temperature and liquid pH extremes).
BioTherm Eliminator contains environmentally safe digestive chemistry that is very efficient in its treatment of organic wastes -including cellulose and Struvite, and provides organically safe bacterial nutrition to sewage which speeds up sludge breakdown, while removing the waste stench. Safe chemistry within BioTherm lubricates, cleans, protectively coats all surfaces, prevents corrosion, and provides environmentally safe antiseptics; all in a working zone from about -20°C to 80°C (0°F to 175°F).
- Sewage contains two types of bacteria: aerobic bacteria which need oxygen, and anaerobic bacteria which thrive in an airless environment; in fact anaerobic bacteria can't survive in an aerobic environment, and that's important to note. Anaerobic bacteria in sewage produce the stinking gasses while the aerobic bacteria break sewage down, but do not generate odour. Therefore, as long as there is a sufficient supply of air to the tank, the aerobic bacteria thrive and overpower the anaerobic bacteria, assuring that the holding tank system remains odour free.
- Holding tanks reek when they in effect become septic tanks. The reason is because septic tanks are an airless environment. To solve this we need only provide a sufficient supply of fresh air, in and out of the tank. I.e. normal residential homes, hooked up to a city sewage systems, use sewage vent lines of 3"; dia. minimum, the same size as the waste line. We note that many wastewater tanks suffer from inadequate fresh air vent line capacity, so an in-tank solution is required here.
- Anaerobic bacteria in sewage produce a variety of sulfur monoxides and dioxides (which are the malodorous gasses), methane, which has no odour but is flammable, and carbon dioxide which also has no odours but creates the environment in which the aerobic bacteria cannot live, and causes the anaerobic bacteria to thrive. Carbon dioxide is motionless and ambient; it lies like a blanket on top of any pool of sewage, whether inside a holding tank or a sewage pond. So, unless there is a sufficient flow of fresh air through the tank allowing it to disperse, carbon dioxide will suffocate the aerobic bacteria and create the perfect environment for the anaerobic bacteria to take over. The system then becomes septic, resulting in a foul environment.
Holding tank sewage treatment and odour control is accomplished by:
- Adding a small amount (90ml/90 L or 3oz/20 gal) of BioTherm Eliminator to the waste system which accelerates sewage breakdown into liquid and removes the stench. This will also clean the lines, fittings, valves, tanks walls, of sewage debris, preventing blockages.
- Ensuring the vent lines are always open so fresh air can enter.
