Powerful antimicrobial chemicals (also known as disinfectants) are increasingly found in household cleaners, from laundry detergent to kitchen cleaners. Research has shown the most common disinfectants, namely Chlorine bleach, Ammonia, Triclosan/Triclocarban, Ammonia Quaternary compounds (Quats), and Nano-silver used in cleaners could have serious health consequences and disrupt your onsite treatment system.
The main sources of cleaners that contain harmful chemicals are (in order of concentration):
1. Automatic dish-washing detergent
2. Liquid fabric softener
3. Toilet bowl cleaner
4. Laundry detergent
Product Labeling Laws.
Current labeling laws don’t require listing what cleaning products contain. Compounding this, the EPA has required the removal of phosphates (nutrients that cause algae blooms in lakes and rivers) from cleaning products. However, the phosphates were replaced with quaternary compounds to still be effective against bacteria.
Many of these are the worst offenders that disrupt a septic system and some are actually labeled “Safe for Septic Systems.” If no information is given on the label, ask for an MSDS (Material Safety Data Sheet) from the product manufacturer.
More than 97 percent of water on earth is salty and nearly 2 percent is locked up in snow and ice. That leaves less than 1 percent of water to grow crops, cool power plants and supply drinking and household water. Governments, NGOs, residential and commercial builders and architects are turning to onsite wastewater reuse systems as a solution to increasing water scarcity and energy costs associated with the treatment and distribution of municipal water and wastewater.
NSF/ANSI Standard 350 and 350-1 establish material, design, construction and performance requirements for onsite residential and commercial water reuse treatment systems. They also set water quality requirements for the reduction of chemical and microbiological contaminants for non-potable water use. Treated wastewater (i.e. treated effluent) can be used for restricted indoor water use, such as toilet and urinal flushing, and outdoor unrestricted water use, such as lawn irrigation.
NSF/ANSI Standard 245 defines total nitrogen reduction requirements to meet the growing demand for nutrient reduction in coastal areas and sensitive environments. NSF/ANSI 245 covers residential wastewater treatment systems with rated capacities between 400 and 1,500 gallons (1,514 and 5,678 liters) per day.
We can evaluate any kind of system, regardless of treatment technology, in test facilities in the U.S., Canada and Europe.
To achieve certification, treatment systems must produce an acceptable quality of effluent during a six-month (26-week) test. System service and maintenance are prohibited during the test period.
