Why do you need an RO storage tank?
An RO storage tank holds reverse osmosis water so you have plenty to use when you need it. A reverse osmosis system makes water slowly. It takes one minute to produce two to three ounces of RO water. If you were to turn on your faucet for a glass of water at the actual membrane production rate, then you would have to wait at least 5 minutes for it to fill. With a storage tank, your glass fills instantly.

What does a reverse osmosis system remove?
A reverse osmosis system removes dissolved solids like arsenic and fluoride through the RO membrane. An RO system also includes sediment and carbon filtration for a broad spectrum of reduction. The carbon filters in an RO system remove chlorine and bad taste and odors, and the sediment filter removes dirt and debris
Does a reverse osmosis system remove…
- Fluoride? Yes.
- Salt? Yes.
- Sediment? Yes.
- Chlorine? Yes.
- Arsenic? Yes.
- VOCs? Yes.
- Herbicides and pesticides? Yes.
- Many other contaminants? Yes. The contaminants listed are some of the most popular ones treated with an RO system, but the system also removes a slew of other contaminants.
- Bacteria and Viruses? No. If your water comes from a city treatment plant, then it should already be microbiologically safe. Reverse osmosis may remove some bacteria, but bacteria could grow on the membrane and potentially enter your water supply. To remove living organisms and viruses, we recommend UV disinfection.

Reverse osmosis system benefits
A reverse osmosis system is one of the most extensive methods of filtration. It removes 98% of dissolved solids, which makes it healthier to drink. A water distiller is the only other drinking water system that also reduces TDS, but it’s less efficient than an RO system.
- Harmful dissolved contaminants reduced
- Sodium reduced
- Bad tastes and odors reduced
- More environmentally friendly than bottled water
- Easy to install and maintain
- Fits under the kitchen sink

Does reverse osmosis waste water?
A reverse osmosis system sends water with rejected contaminants down the drain as wastewater, unlike other filters that trap contaminants. As water flows through the system, it’s divided into two streams. One stream carries the filtered water to a dedicated faucet, and the other stream carries the removed salts, dissolved pollutants, and minerals to the drain.
The brine or “wastewater” carries rejected contaminants from a reverse osmosis system to the drain. 4 gallons of water exits the drain for every gallon of water produced. But the brine water is used for a purpose, so it’s not exactly wasted. The wastewater in an RO system helps clean the water, just like a dishwasher uses water to clean dishes or a washing machine uses water to clean clothes. However, it’s our job in caring for the environment to minimize the amount of water sent to the drain and increase the efficiency of the RO system.
How to reduce wastewater in an RO system
- Add a permeate pump. Installing a permeate pump to a reverse osmosis system is the best way to increase its efficiency. Permeate pumps reduce the wastewater from an RO system by 75 to 80%. Not every reverse osmosis system is designed to use one, so make sure the one you choose is plumbed for an additional pump.
- Choose an RO system with an automatic shut off valve. An ASO valve stops the flow of water to the drain once the storage tank is full.
- Use the RO reject water for landscaping or artificial lakes. Drain water has higher levels of total dissolved solids (TDS), but it’s safe to use in your lawn or garden.
The Neo-Pure 4300 DLX is one of the most efficient RO systems because it includes a permeate pump and an ASO valve.
Is reverse osmosis good for the environment?
When the water you use drains from your home, chemicals and other contaminants must be removed before it’s recycled. Wastewater is either sent to a water treatment plant and diluted to make it easier to treat or to riverbeds for nature to filter through the hydrologic cycle.
A reverse osmosis system makes waste treatment more efficient. Reverse osmosis water drained from your home is already free of chemicals since they’ve been removed in the carbon filtration stage. The leftover brine water has just a slightly higher concentration of dissolved inorganics. RO systems speed up the recycling process because no new chemicals are introduced into the water supply after RO water drains from your house.
