Should you use a lagoon for your water treatment system?
One appeal to using lagoons is that they generally require less energy than other treatment systems and have lower operation and maintenance costs. That being said, proper performance still requires some form of ongoing maintenance and upkeep.
How do saltwater lagoon swimming pools work?
You can find natural saltwater lagoon pools in places like Mozambique and Bolivia. You can also choose to have a saltwater pool installed in your own home. A saltwater pool gets cleaned using a filtering system called a salt chlorine generator. The system uses electricity to turn salt into chlorine, which cleans the pool.
Why is algae a problem in lagoon wastewater treatment?
Since algae interferes with efficient lagoon-based wastewater treatment and causes odors, it’s important to prevent it or at least keep it in check. Following are some popular methods for coping with lagoon algae.
How does a lagoon treatment system remove phosphorus from wastewater?
In a lagoon treatment system, phosphorus is also removed by assimilation into the biomass of algae cells. As the alkalinity increases during daylight hours, the phosphate is precipitated and settles out of the wastewater.
How do you maintain a lagoon?
Lagoon maintenance is easy, if the following precautions are taken:Keep the berms (outside and inside) mowed. ... The lagoon is not a trash dump. ... Do not allow paints, paint thinner or large quantities of chemicals to flow to the lagoon. ... Lagoons may develop odors when they “turn over” in the spring and fall.More items...
What effect does a water softener have on a septic system?
Studies have shown that water softener regeneration wastes do not interfere with the septic tank system drain field soil percolation, but because of the polyvalent water hardness cations in the regeneration discharges improve soil percolation particularly in fine-textured soils.
How does salt water treatment work?
The high concentration of sodium ions in the salty water displaces the calcium and magnesium ions the resin, and the resin becomes once again covered with sodium ions. The salty rinse water, calcium and magnesium ions are flushed down the drain, and the system resumes normal operation.
Why do you put salt in water system?
Hard Water Issues Without a sufficient supply of salt in the brine tank, water softeners cannot execute an optimal regeneration. That means softening capacity isn't fully restored, so hard water will continue to flow through the taps in your household, causing a variety of problems.
Does salt water damage septic system?
The heavy salt water can actually lift the sludge from the bottom of the tank, washing it into the downstream components. Septic tanks that receive water softener brine have been observed to have no distinct layers of sludge, scum, and clear zone, as they should have in order to perform primary treatment.
Does water softener salt hurt a septic system?
Water softeners and septic systems Some of these studies, like the ones that were done by the University of Wisconsin and the National Sanitation Foundation (NSF) concluded that water softeners do not pose a significant threat to septic systems.
How much does a saltless water softener cost?
The initial cost of a salt-free water conditioner runs from between $300 to $4000 depending on the size of the unit. Salt-free softeners work not by removing the calcium and magnesium, but rather claim to suspend the ions and preventing them from building up as they flow through your plumbing.
Do saltless water softeners really work?
Unfortunately, salt-free water softeners don't work because they don't exist! “Salt-free water softener” is a misnomer for salt-free water conditioners – all water softeners use some kind of salt to remove hard minerals from your water.
How do you soften pool water?
The first option to make your pool water softer is to drain some water and add some new, fresh water. Start by turning off your pool. Then drain just a few inches of water from your pool with a pump. If you have access to a fresh (not hard) water source, use that to replace the drained water.
How long should block salt last?
If your water softener is non-electrical block salt, you do not usually need to have it serviced until after 10 years, after which we would recommend a water softener health check every couple 1-2 years, to ensure your softener is working as it should.
Which is better salt or no salt water softener?
The choice is clear—only a salt-based water softener is proven to provide softer water, healthier skin, and no scale buildup or soap scum. A salt-based system is a better investment.
How long does a 40 lb bag of water softener salt last?
Your salt consumption will depend on the level of water hardness (minerals in your water) and the amount of water your household consumes. The average family of four with hard water (7-10 grains per gallon hardness level) will use about one 40-lb bag of salt each month.

What is lagoon water?
To start from the beginning, a lagoon is a large, manmade body of water that is designed to receive, hold, and treat wastewater before it’s considered safe and returned to the environment. In a way, lagoons are like holding tanks where sewage enters at one end and then beneficial bacteria and other organisms work to break down various organic components over time. These bodies of water are constructed and lined with material, such as clay or an artificial liner, that will prevent any leakage into the groundwater. While a lagoon can exist alone, they’re also commonly installed as part of a system in a series. This form of wastewater treatment comes in three main variations: anaerobic (without oxygen), aerobic (including oxygen), or facultative, which is a combination of the two oxygenic conditions.
Why are lagoons so good?
THE PROBLEM: Lagoon Challenges. Lagoons are great because they don’t require much daily maintenance and often treat rather naturally. However, there are some long-term issues that can’t be avoided, so a maintenance plan needs to be put in place.
Why is sludge in lagoons so slow?
This causes an issue because there is only a finite amount of space, often resulting in the need for dredging and removal that comes at a high cost.
What is a traditional lagoon system?
A traditional lagoon system is a two part system. A traditional system has: Plumbing from the house: pipes with clean outs that carry wastewater to the lagoon. Lagoon: shallow body of wastewater where final treatment and reintroduction of wastewater into the environment occurs.

How much wastewater can be seen in NDEQ?
NDEQ allows a maximum seepage of 1/8 inch per day. The wastewater has not been fully treated so it must be prevented from escaping into the groundwater. The hollowed out area is formed by dikes or berms of soil.
Why do we need a lagoon?
The idea behind a lagoon is to allow nature to decompose the BOD (fecal matter in most cities) and ammonia so that clean, clear water is going out in the effluent. Most wastewater lagoons have effluent limits on BOD and TSS, and a few also have limits on pH, dissolved oxygen and ammonia. In some industries, such as wineries, ...

Algal blooms in a wastewater lagoon, especially an aerated lagoon, provide little benefit and cause all sorts of problems: High TSS and BOD5: High TSS, or total suspended solids, and high biological oxygen demand go hand in hand, as each mg of algal TSS results in about 0.5 mg of BOD. Most of the effluent TSS and BOD in ...
Why is algae shading?
Shading: Because algae is reliant on sunlight to grow, anything natural or artificial that blocks light from entering the water will prevent it .
Why do algae have low oxygen?
Low oxygen: Algae create oxygen during the day and use it up at night, leaving less oxygen available for BOD-consuming bacteria to use. Sudden algal die-offs, either natural or caused by an additive, can also deplete oxygen and cause low dissolved oxygen (DO) conditions.
What is the most important factor in controlling the growth of algae?
Retention time: According to the late Linvil Rich, the founder of Clemson University’s Department of Environmental Engineering and Science and a pioneer in lagoon technology, hydraulic retention time [HRT] is the most influential factor in controlling the growth of algae. The shorter the retention time, the less opportunity for algae to grow.
Anaerobic Lagoons
If the wastewater is not aerated, the lagoon may function in an anaerobic mode in which organic matter is fermented to simple organic acids and eventually converted to methane.
Facultative Lagoons
Facultative lagoons may be actively aerated or simply have oxygen diffusing from the air into the surface water. Ideally, there are both aerobic and anaerobic bacteria present, active and contributing to the removal of contaminants.
Aerated Lagoons
Lagoons are frequently aerated with surface aerators that mix a zone around the aerator as well as increase the dissolved oxygen.
Conclusion
Every type of wastewater lagoon has its pros and cons, which is why there are so many options. But no matter which one you choose, you will need an effective solution for keeping your lagoon clean and running efficiently.
