North Texas Septic
When disinfection of secondarily treated wastewater effluent is required and you are using chlorine tablets it is important that you use chlorine tablets that are made from calcium hypochlorite and is certified for wastewater disinfection by the EPA. They are very reactive and will kill 99% of bacteria present in the effluent within 10 minutes. You can find these tables at your local hardware store or at septic supply stores. They are commonly referred to as Septic Tablets.
WARNING: DO NOT use swimming pool chlorine tablets in your disinfection system. The chlorine in these tablets are made from trichlorisocyanuric acid. Swimming pool tablets dissolve more slowly than septic tablets and do not thoroughly disinfect the effluent. Additionally, there is a danger of explosion using swimming pool tablets since the tablets will release an explosive gas called nitrogen chloride due to the fact that they are not totally immersed in water at all times while in use. The EPA does not approve swimming pool tablets for wastewater effluent disinfection.
Liquid bleach dispensers. You can save hundreds of dollars by using regular household bleach. This bleach contains the same active ingredients used in the expensive septic chlorine tablets. You must however install a liquid bleach dispenser approved by the TCEQ. The automatic bleach dispenser we market and install for our customers has been patented for over a decade. This automatic bleach dispenser was designed and constructed to withstand the harsh effects of bleach and provide years of trouble-free use. This is a proven disinfection device that meets the applicable requirements of NSF standard 46 for chlorine dispensers.
Certification requires the device to be used with 6% sodium hypochlorite (household bleach). The residential dispenser holds about 4 gallons of bleach. For a family of 4 that has average water consumption, the automatic bleach dispenser will use about one gallon of bleach a month. We can also accommodate your commercial needs with a larger version. This equates to approx. $12-15 dollars per year as apposed to the $90 for a small tub of tablets.
